My door actuators are going out on all my doors started with the driver door then the passenger rear door and now my driver rear door. This poses serious safety concerns, for example when Class Vehicles are involved in vehicular accidents because the occupants may become entrapped when the Door Actuator Defect prevents an occupant from unlocking the doors. Furthermore, this defect jeopardizes the safety of Vehicle occupants given that not all doors are capable of being manually unlocked from the exterior. Also another thing I would Like to add is that when I try to unlock the doors my only two working doors are my passenger front and back driver rear door but like I said it is starting to go out but I have to unlock them first then I have to use the key to the driver door just to get in cause if I do It the other way the car alarm will go off.

On Monday, January 5, 2026 at approximately 3:15 p.m. Pacific Standard Time, in the middle of stopped traffic (leftmost lane, southbound on Van Nuys Boulevard near the Saticoy Street intersection in Los Angeles, California), the vehicle, a 2023 Toyota Corolla Hybrid LE, suddenly started slowly moving backward. The driver pressed on the brake pedal, but the vehicle did not stop. In a panic, the driver removed the key from the ignition, which immobilized the vehicle. While in the middle of traffic, the driver contacted a family member for assistance and the vehicle was towed to the driver's residence. On the following day, January 6, 2026, the vehicle was towed to a service center for inspection. It is unknown if the warning messages observed January 6, 2026 were due to the vehicle being towed. At the service center, a tire was replaced and the brake system was flushed, at the owner's expense. Afterward, the driver continued to operate the vehicle. As of August 5, 2026, this incident had not recurred.

I purchased a 2023 Toyota Corolla LE as a Toyota Gold Certified Pre-Owned vehicle on March 8, 2026 at 61,387 miles. Within 30 days of purchase I began experiencing the following safety concerns: •Vehicle revs to 5,000-6,000 RPM unexpectedly •Violent jerking while driving •Vehicle stalls On April 7, 2026 I brought the vehicle to the selling dealership. The technician confirmed experiencing the jerking and stalling personally during a test drive but documented it as “common operation” and “operating as designed.” I disagreed with this assessment in writing on their service document. A second Toyota dealership subsequently found cracked motor mounts and transmission mounts in multiple locations on a 3 year old vehicle. Replacement of these components did not resolve the issue. Transmission fluid drained at service was nearly black in color on a Gold Certified vehicle that supposedly passed a 160-point inspection including transmission health check. The vehicle is currently at the dealership unresolved after nearly two weeks. The stalling and RPM surging present a serious safety hazard particularly at highway speeds. I am requesting this be investigated as a potential safety defect.

Component: VISIBILITY / SUN VISOR Vehicle: 2023 Toyota Corolla Both the driver-side and passenger-side sun visors in my 2023 Toyota Corolla have failed within approximately two years of normal use. The visors no longer remain in their intended position and instead fall downward unexpectedly. When this occurs, the visor drops directly into the driver’s field of vision, creating a significant safety hazard by obstructing forward visibility while driving. This condition can happen without warning and requires the driver to physically move the visor out of the way, causing distraction and increasing the risk of an accident. The vehicle has not been modified, damaged, or subjected to abnormal conditions. The visors were used only as intended. Sun exposure is a normal and expected condition for this component, and failure under these circumstances indicates a potential defect in materials or workmanship. Both visors failing in the same manner suggests a systemic issue rather than isolated wear and tear. The vehicle was taken to a Toyota dealership, where I was initially told the repair would be covered under the manufacturer’s warranty. However, the claim was later denied and classified as “wear and tear” due to sun exposure. Given the function of sun visors, this explanation is not reasonable. This issue presents an ongoing safety concern due to impaired driver visibility. I am submitting this complaint so that this defect can be reviewed and tracked for potential broader impact.

I am experiencing persistent and unresolved issues with the infotainment and display system in my Toyota Corolla, primarily involving Apple CarPlay overriding the driver display. Even when I manually disable the setting that allows CarPlay/navigation to take over the display behind the steering wheel, the system does not retain this setting. After turning the car off and restarting it, the navigation/map interface reappears and overrides the driver display again. This behavior is extremely distracting while driving and interferes with my ability to safely view normal vehicle information. It has created multiple situations where I felt at risk of a collision due to unexpected display changes and distraction. In addition, there are ongoing system malfunctions including: •Volume controls becoming unresponsive (the slider does not adjust sound), requiring the system to be restarted to function again. •Intermittent failure of the phone connection/charging port, where the device does not connect properly to the system. A prior software update temporarily addressed one issue, but the core problems persist. I have been attempting to resolve this through Ardmore Toyota dealership in PA for approximately one year without a meaningful fix or access to a qualified technician. This appears to be a recurring software or system defect that affects driver attention and vehicle operation. I am concerned this creates a significant safety risk for myself and others on the road. No one has taken me seriously even after I’ve gone to several Toyota dealerships over and over and I explained my concerns and they promise that I’ll be on a list of waitlist to be seen by a field tech technician however that has never happened and they are refusing to provide assistance.

I have a Hybrid version of the 2023 Corolla in the SE trim. Everytime the car is cold (engine just started), and I'm pressing the brake, I can hear some clicking noises similar to a CV Axle noise when they are bad. That braking noise goes away as the car heat up. The noise is sensitive to speed, it changes frequency with it. I haven't experience loss of brakes but I'm concerned with the noise and the possibility of it.

Description of problem/issue: Dear Reader: I recently purchased a new (certified preowned) vehicle and ever since then I have been experiencing some concerns with its handling on the road. This letter seeks to communicate this matter to the proper establishment for some possible recourse. On level roads while the steering wheel is centered straight up (near/over 40mph), the car tends to automatically glide to the left of the lane or coast quickly to the right and won’t stay centered in the lane very long without driver input to steer the car back to the center of the lane. Then when re-centering the car it roams in the other direction, and so forth (an oscillating effect). The issue is that the car diverts from the center of the lane and to maintain the center of the lane the driver has to constantly work at pulling the vehicle back to center. This is not the type of driving performance that I would expect on a new or certified new vehicle. It is both a nuisance and a hazard having to constantly steer the vehicle to center up in the lane. The car’s auto Lane Assist and Departure Assist and auto Steering Assist features are turned off during this time. And even when all these Driver Assist Features are turned back on the drifting/pulling pattern is quite pronounced or seems to be compensating in my opinion. A Google search of the term “2023 Toyota corolla pulls to both sides” produces some great results as to the possible cause and effect. I have never driven a vehicle that diverts so quickly from its own lane so shortly after the driver’s hand is removed from the steering wheel. Nevertheless, the issues that I pointed out remains very alarming and nerve-racking for me! For safety reasons I’m still not pleased with how the car handles on the road. I wonder if there are any Safety Recalls, current or pending, concerning any of the steering or alignment components/features that would help resolve this problem?

When driving at night, there is a shadow in the headlight, that shines onto the road and makes driving at night difficult. This shadow looks like it comes from a tall screw or bolt in both headlights. The lights work correctly, but the shadow causes the driver to have a dark "spot" in the beam of light, which then makes it hard to see clearly while driving in dusk, or darkening circumstances. I took the vehicle in to the Toyota Dealer where I bought it and had them investigate this. They said they couldn't repair it, as it was part of the construction of the headlight itself. The Toyota repair people did see the shadow when the lights were turned on to face a wall in a darkened garage bay.

- 11007447Some 2020 2024 model year Corolla vehicles may exhibit a vibration or rattle noise from the right-hand engine mounting insulator sub-assembly. This condition will usually go away when the engine Revolutions Per Minute (RPM) are above idle. This condition is typically found on vehicles in warm climates/weather. No Diagnostic Trouble Codes (DTCs) are associated with this condition. This condition does not affect the operation of the vehicle.
- 11007445The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain (see Figure 1), frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.
- 11007444To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
- 11007443Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: Minor damage: requires only buffing to repair. Moderate damage: usually requires neutralizing, color sanding, and buffing. Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

- 11006153Some 2020 2024 model year Corolla vehicles may exhibit a vibration or rattle noise from the right-hand engine mounting insulator sub-assembly. This condition will usually go away when the engine Revolutions Per Minute (RPM) are above idle. This condition is typically found on vehicles in warm climates/weather. No Diagnostic Trouble Codes (DTCs) are associated with this condition. This condition does not affect the operation of the vehicle.
- 11006151The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain (see Figure 1), frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.
- 11006150To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.
- 11006149Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: Minor damage: requires only buffing to repair. Moderate damage: usually requires neutralizing, color sanding, and buffing. Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.
- 11005153Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces. This material protects from acid rain, environmental fallout, and rail contamination.
- 11005149Vehicles may occasionally be subjected to contamination by airborne iron particles shed from railroad tracks, train wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface. These particles are often difficult to see on dark color paints but can be easily felt when brushing a hand across horizontal body surfaces such as the hood, roof, or deck lid.
