This Complaint is not about a specific incident, but about excessively-brilliant (blinding) headlights. In the flow of traffic, the blinded drivers far outnumber the vehicle using blinding headlights. The area those headlights cover spreads out so WIDE, the blinded driver is not able to see the side of the road. Insurance companies may say this problem does not cause accidents; but, I believe that is because many drivers do not dare risk driving at night. Excessively-brilliant, blinding, headlights should be BANNED and Recalled. Those headlights are a terrible safety concern and should have been banned years ago.
Unknown—he only performed the inspection, as I am a Lyft driver and my account was suspended due to a recall issued by the NHTSA.
The contact owned a 2011 Toyota Corolla. The contact stated that while he was driving at 40 MPH, another vehicle that was speeding caused a multiple vehicle collision. During the collision, the contact was in the middle lane when the speeding vehicle crashed into a vehicle in the left lane, and that vehicle merged violently into the middle lane, causing the contact to rear-end the vehicle in front due to the driver abruptly stopping. During the attempt to stop, the vehicle failed to decelerate sufficiently. Upon impact, the frontal air bags failed to fully deploy, as they only partially emerged from the housing. The failure experienced was a loss of braking effectiveness at 40 MPH that resulted in a rear-end collision, during which the frontal air bags failed to deploy. The vehicle was towed to a family member's home. The tire pressure warning was the only warning light on at the time of the crash. The driver was injured. Injuries sustained were lower back, right side ribs, and neck pain that required medical attention. The vehicle was deemed totaled by insurance. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 124,000.
I am submitting a safety concern regarding airbag non-deployment involving my former vehicle, a 2011 Toyota Corolla LE (VIN: [XXX] ). This vehicle was subject to multiple Takata airbag recalls, including a 2018 front airbag recall and a May 2020 Takata non-deployment and seatbelt pretensioner interim recall. Beginning in Spring 2021, the airbag warning light illuminated intermittently. On May 30, 2024, diagnostic trouble codes B1813 and B1818 were recorded, indicating faults involving the driver and passenger airbag squib circuits and potential center airbag sensor assembly involvement. A recall-related repair was completed on June 6, 2024 with installation of a Harness Kit (04009-98112) under extended warranty associated with a class action settlement. Following subsequent service, the airbag warning light was no longer illuminated. After these repairs, the vehicle was later involved in a rear-end collision in which the airbags did not deploy. The vehicle was declared a total loss and is no longer in my possession. Given the vehicle’s documented history of airbag system recalls and prior SRS fault codes, I am submitting this incident for safety documentation and review.

p195 /65r/15 91 h. yokohama avid ascend. i bought 4 tires on 04/11/22 at kinderhook toyota my car had 61008 miles on it. on 08/04/25 brought my car to same dealer was told i needed new tires. multipoint inspection said front tires had 3 32nd of tread and back tires had 4 32nd of tread wear left. my car had 80678 miles on it. the tires lasted less than 20000 miles. they had an 85000 mile warranty on them. i can understand tires lasting maybe 60000 miles or so, but only 20000 miles? was told i can contact your office about this. could not find a different page for a non- accident problem. dealer said to contact yokohama customer service and kinderhook toyota would send the tires back.
The contact owns a 2011 Toyota Corolla. The contact stated that while driving at an undisclosed speed, the contact heard a loud knocking sound coming from the engine compartment. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the oil pressure sending unit had failed and needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 150,000.
Part of a customer support repair program through Toyota. It expired, and Toyota Customer Care at 1-888-270-9371 told me to file a complaint at NHTSA.gov. So I am filing a complaint. The paint is peeling on my car rapidly and I have missed the support program deadline because it was not happening in the timeframe they created for this problem. But there is no reason for my pain to be peeling like it is other than manufacture error.
I am writing to formally request a recall or resolution for a significant defect in my [2011, Toyota, Corolla] vehicle, which I purchased in 2011. Over time, the paint on my vehicle has begun peeling extensively, affecting not just the aesthetics but also potentially the resale value and durability of the car. This issue appears to be a widespread problem among vehicles of similar make and year, suggesting a potential manufacturing defect. Given the extent of the paint deterioration, I kindly request that Toyota Company acknowledge and address this issue through a recall or appropriate corrective measures. Vehicle Details: Make & Model: Toyota, Corolla Year: 2011 VIN: [XXX] Current Mileage: 80,000 Estimated I would appreciate a prompt response regarding my request. Please let me know the next steps in addressing this concern, including any available remedies Toyota may offer. You may contact me at [XXX] or [XXX] at your earliest convenience. Thank you for your time and attention to this matter. I look forward to your response. Best regards, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2011 Toyota Corolla. The contact stated while driving 20 MPH, the accelerator pedal was released, and the vehicle made an abnormal sound. The check engine and traction control warning lights were illuminated. Additionally, the vehicle hesitated to accelerate while driving. The vehicle was taken to AutoZone, where it was diagnosed that the transmission valve body needed to be replaced. The vehicle was then taken to the dealer, where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 86,000.
1.- Bolsa de aire. Si me lo solicita, por supuesto puedo llevarlo a inspección. 2.- Se puso en riesgo ya que pudo haber sido otro tipo de accidente y las bolsas de aire no se activaron. Yo usaba el cinturón de seguridad. 3.- No ha sido confirmado por un distribuidor local. 4.- No no ha sido inspeccionado por el fabricante. 5.- No hubo ningún tipo de luces o indicador de la falla de las bolsas de aire. I had an accident because a dog ran away on a road and hit my car in front and I was going at a speed of approximately 20 mph, breaking my front bumper and the airbags did not activate.
While driving on a straight road steering wheel suddenly jerk hard left and right several times for just a few seconds and then went normal. This caused the car to cross lane into oncoming traffic. Fortunately steering went to normal before causing head on collision. I took the car into local Toyota dealer to be checked. They could not duplicate trouble. No warning lamps lit up and no fault codes per dealership technician.
While driving my car seat seat (driver side) starts to over heat. I do not have heated car seats.but within the past few weeks I have noticed that my car seat started to heat up. At first I thought it was because it has been sitting in the sun all day, but as the driving progressed in the fact this is happened three times I feel that there is a flaw In the interior.
Fail to pass Texas vehicle safety & emissions inspection.
Sunroof exploding while driving. Could cause safety issues if inner compartment was opened when the incident occurred. The vehicle has not been inspected yet but I will have a glass company replace the sunroof asap. No symptoms of any fault was present before the incident occurred.
Paint peeling on the roof.
My Transmission On My 2011 Toyota Corolla Has Been Experiencing So Troubles .when being put into gear to drive it acts as if it's in Neutral and put on reverse the same thing . At first it was driving fine and Then a week later when you put it on driver I notice my rpms when getting ramped up but my it was slowly going up to 20 miles pre hour and you can fill it slipping. Now my car is undriveable
The contact owns a 2011 Toyota Corolla. The contact stated while driving approximately 70 MPH, the air bag warning light illuminated. The contact also stated the air bag warning light was frequently illuminated; however, the warning light no longer was illuminating. The vehicle was previously repaired under an air bag recall. The vehicle had not been diagnosed or repaired since. The manufacturer was not notified of the failure. The approximate failure mileage was 43,600.
The contact owned a 2011 Toyota Corolla. The contact stated while her husband was driving at 15MPH, another vehicle ran through a red light and crashed into the front driver's side of the vehicle. No warning lights illuminated. The air bags did not deploy. The police and the fire department arrived at the scene and a police report was filed. The contact stated that no injuries were reported on either side. The vehicle was totaled and towed to the service center. The manufacturer was notified of the failure. The failure mileage was approximately 150,000.
The contact owns a 2011 Toyota Corolla. The contact stated that the headlights and fog lights were blinking then became inoperable. The air bags, oil, and fuel warning lights were illuminated. Additionally, the tires were losing air. The contact had to plug an item into the aux for the glitch to stop. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified but no further assistance was provided. The failure mileage was approximately 72,000.
Sunroof suddenly exploded while driving 40 MPH on a highway No evidence of projectile was in the car. The glass was volcanoed up. It was around 50 degrees outside. I was immediately confused as to what happened. I was traveling in a merging lane and could have vered into the other lane and hit another car. Glass was Falling down onto me and the passenger seat. No police were called I took the vehicle to a glass repair. Insurance was not involved as my dectiable would not have been meet for the cost of the repairs. No warning or any symptoms the sunroof glass from the car. Itjust suddenly exploded for no reason.
I was notified of the air bag recall a year ago but the car dealerships in my area does not have the parts and I need to use my vehicle daily. So I am not sure what to do from here for that but I believe that the appropriate time to remedy this recall has past already and the fact that we have our children riding with us and we are unaware that their life is in danger or because we can not get it fixed is not acceptable. Then on top of that I am having issues like when my 2011 Corolla is sitting idle it will rev up the engine without touching the gas pedal and does this randomly and without warning and also while I am driving around 55 MPH on the interstate or highway sometimes it will dramatically drop and lose about 10- 15 MPH speed for no reason and this happens randomly as well. And this fluctuation happens during cruise control the most so I no longer even use that function. Also both headlights have moisture in them and are so fogged up now that visibility is almost impossible at night now. Also the weather striping around all my windows have dry rotted and broke off and there is practically nothing left of stripping anymore. Then the center dash above the radio just broke and gave out under my phone holder while driving, it broke into about 15 different pieces. I know that my phone or the holder is even close to heavy enough to cause the dash panel to cave in like that. I called to get a price on the dash and it was like $250+ and who can afford that for a piece of plastic. Lastly my driver and passenger seat will get stuck if you try adjusting them and sometimes it will let you move the seat but to do so you have to hop up and down for several minutes and throughout the adjustment to get the seat to move in any direction.
Car accelerates hard from stationary idle. happening for several weeks. yesterday accelerated from idle at a 4 way stop intersection almost caused an accident. very scary. not comfortable using it until problem remedied.
While driving on the highway, the car began to drift side to side, feeling like it IS sliding on ice. I feel very unsafe and hope to be able to get some answers to resolve the issue.
TL* the contact owns a 2011 toyota corolla. The contact stated that the vehicle independently accelerated while driving at an undisclosed speed, without warning. The vehicle was not taken to be diagnosed nor repaired. Neither the dealer nor the manufacturer were notified of the failure. The failure mileage was approximately 80,000.
To whom it may concern, we have experienced anomalous behavior in our vehicle that we believe IS due to malware. We were referred to report this from the public service announcement: https://www.ic3.gov/media/2016/160317.aspx#fn1 1. Our engine will suddenly accelerate and decelerate without our foot pressing on the accelerator to cause this change. It will also slowly change when cruising at a constant speed, the car will increase speed gradually with very light pressure on it. 2. Our cruise control will reset the speed at various times, we will be going 70 mph on the interstate and it will gradually slow down without us disabling it with a brake press or switching it off. (My wife does not use the cruise control and cannot verify this.) 3. Our radio will turn on suddenly without pressing the power button. 4. Our radio will eject a cd without us having the radio on. 5. Our air conditioner light will turn on and off intermittently without us turning it off. (I cannot verify this although my wife has observed this behaviour.) 6. Our air conditioner will function intermittently. Sometimes it will operate normally and other times it IS completely nonfunctional. Occasionally it will work at lesser levels but IS still functional. respectfully, norman and monique mapes
NHTSA’s Office of Defects Investigation opened these reviews into vehicles including this one.
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW. The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications. The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU. In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment. FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle. Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW. These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes. An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time. In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU. This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners. Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW. The risk associated with the ASIC is equally shared among all OEMS involved in the investigation. The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage. There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation. The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU. If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC. Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC. All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled. In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024. With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.
