  I am reporting a severe, recurring safety hazard on my 2020 Toyota Corolla. The vehicle suddenly displays 'Drive-Start Control Malfunction' and completely cuts off engine power in motion, leaving the car stranded in active traffic. This happened after accelerating from a STOP sign on a main avenue. This is an inherent manufacturing defect present since delivery. In total, this chronic electrical surge has burned through 6 batteries and 3 Engine Control Modules (ECMs) at different mileages. Within the first weeks of purchase, it burned its first battery, which was replaced at Toyota and documented under the VIN history. Dealer staff deceptively called it 'normal,' leading me to replace subsequent batteries at AutoZone. [XXX] Toyota received the vehicle 4 times for this exact failure under Service Advisor [XXX]. They replaced the ECM twice, replaced a destroyed battery on a third visit just 400 miles later, and during this fourth visit on XXX, they only diagnosed the current burned ECM. Under Order XXX, I paid for 4.5 hours of specialized diagnostic labor, but the shop negligently just swapped parts and ignored the root cause. On XXX, an Operations Chief from Toyota Corporate called me under active BEC Case #XXX. He issued a final, verbal denial for Goodwill assistance based solely on mileage and age. Crucially, the Operations Chief explicitly admitted during the call that Toyota does not know what is causing the ECMs to burn out and does not know how to perform the proper diagnostic procedure to isolate the electrical root cause. He gave me to understand that my only option was to pay to replace the computer again and just put the car back on the road without a real fix. He actively refused to provide this denial in writing, forcing an unsafe vehicle back onto public roads. I have all four invoices to prove this chronic pattern.

  What component or system failed or malfunctioned: complete slave cylinder failure resulting in loss of braking and ability to shift. Luckily I was traveling at a low rate of speed when this happened, but if this happens to anyone on the freeway or while turning against traffic for example they would have no control of their car and could be seriously injured. I took it to the dealership and they diagnosed it as a slave cylinder failure at only 70k miles. This is incredibly pre-mature. The vehicle has not been inspected by the manufacturer, only the dealership but I am trying to escalate the issue. No warnings at all, I regularly get my car serviced on there were no instances of the clutch acting strange or brakes losing power (because the clutch and brakes share the same fluid reservoir) prior to this incident.

  I am unable to lock or unlock the driver’s side door of my 2020 Toyota Corolla using the key fob because the door lock actuator is no longer functioning properly. I must manually use the physical key to lock and unlock the driver’s door. I consider this a significant safety concern because the power locking system is no longer functioning as intended, potentially affecting my ability to quickly secure or access the vehicle, particularly in an emergency. I have contacted Toyota directly to report the issue and request assistance with the repair, but Toyota is currently declining to cover the repair. I am proceeding with having the vehicle repaired independently because I need the door lock system restored to proper working condition. I have also learned that other Toyota owners have reported similar premature failures involving the door lock actuator. I am requesting that NHTSA document and review this complaint to determine whether this represents a recurring defect or potential safety-related problem that warrants further investigation.

  DESIGN FLAW & SAFETY RISK: Toyota critically mismatched the standard battery to the vehicle's electrical charging profile; an AGM battery should be specified from the factory. Engine programming drops alternator voltage during cruising, deeply discharging the battery, and forces high-voltage surges (15V+) into it during deceleration. Because standard batteries cannot handle these rapid recharge loads during deceleration, the internal thermal load routinely overheats and boils the liquid electrolyte, even when brand new. This continuous boiling vents volatile hydrogen gas and discharges corrosive battery acid inside the engine bay. This structural flaw culminated in an immediate safety hazard when the battery physically exploded under the hood, creating a severe risk of engine compartment fire, chemical acid burns, and complete vehicle electrical blackout in active traffic. COLLATERAL DAMAGE & HISTORY: The chronic discharge and boiling of highly corrosive battery electrolyte severely damaged and corroded surrounding critical vehicle components. The acid completely corroded the transmission mount, the metal battery holder restraint, and the body paint. Furthermore, the corrosive boil-over burned off and destroyed several electrical connectors, plastic shrouds, plumbing hoses, and sections of the primary engine wiring cable harness. Since owning this 2020 Toyota Corolla, the vehicle has suffered systematic electrical degradation, requiring a full battery replacement at least once every single year. The exploded battery could not be safely retained due to its hazardous, ruptured state. WARNINGS & INSPECTIONS: No dashboard warning lamps, battery alerts, or diagnostic codes were triggered on the display prior to the physical battery failure. The rupture and electrical blackout occurred instantaneously. The vehicle has not been inspected by police or insurance representatives as no crash resulted directly from the blast.

  FAILED COMPONENT & AVAILABILITY: The manual transmission Concentric Slave Cylinder (CSC) failed internally. Due to caustic hydraulic fluid contamination and severe system pressure loss, I had to replace the internal CSC unit, the clutch disc, the pressure plate, the flywheel, the master clutch cylinder, and the hydraulic clutch lines. The failed components have been retained and are available for inspection upon request. SAFETY RISK: The plastic housing of the OEM slave cylinder cracked internally, spraying caustic hydraulic brake fluid inside the transmission bell housing and completely coating the flywheel, pressure plate, and clutch friction disc. This caused an immediate, sudden loss of hydraulic pressure, forcing the clutch pedal to drop and stick flat to the floorboard. This put my safety and the safety of others at extreme risk, as it suddenly prevented me from disengaging the clutch, shifting gears, or safely dropping the vehicle into neutral while driving in active traffic.CONFIRMATION & REPAIR: A certified Toyota dealership diagnosed the issue and issued an unaffordable repair estimate of $4,800 to fix this recurring manufacturer defect. Because of this extreme cost, I was forced to drop the transmission and perform the entire rebuild myself. The total out-of-pocket cost just for replacement parts was $3,200. The vehicle has not been inspected by police or insurance representatives as no crash resulted. WARNINGS & MILEAGE SYMPTOMS: There were no prior dashboard warning lamps, error messages, or clear physical indicators before either failure occurred. The loss of clutch pedal pressure happened instantaneously. This vehicle has suffered this catastrophic internal failure twice: the original factory-installed unit (part number 31400-19025) failed prematurely at 59,000 miles. The updated replacement part (superseded part number 31400-19027), which suffers from the exact same defective plastic composition, failed again just 40,000 miles later.

  Part is the coolant bypass valve. Toyota has been taken to court but dealership claims now that I’m over 100k miles I can’t do it. There was also a second part about 10 years but I wasn’t clear on the details of the outcome. Toyota has acknowledged this issue in court but failed to do so at the customer level in my case. engine light came on at 97k and now I’m at 104k which is over that 100k mark. Issue is I’ve only take my car to Toyota for repairs. They have known about this but failed to repair or notify me of it. I would have immediately brought my car in at 97k if. I had known. This puts not only me but my 3 kids and entire family at risk every time i drive. This is known to the dealership and they been taken to court for failures to notify customers of this known defect. It’s been inspected by Toyota the last time I took it in about a week ago at 104k miles.

  Windshield Wiper Intermittent setting stopped working, and wipers no long return to their home position. This appears to be a common issue with Toyota. When driving in the rain, the wipers will freeze in the up setting, which is very dangerous for it to occur during heavy rain on the highway causing visibility issues. No warnings of any kind given, the wiper switch appears to just go bad, or wear out over time.

  I am having a problem with my 2020 Toyota Corolla's brakes. I live in [XXX] . In the winter when the car is cold the brakes work normally. When the car has been driven for a while, the car has warmed up, and the brake fluid has thinned, the brakes behave abnormally. When I stop at a red light, after 20 to 40 seconds, the brake pedal slowly drops towards the floor. My understanding is that this could indicate a problem with the master brake cylinder. My fear is that there could be a sudden failure of the cylinder causing an accident. I brought the car to Rudy Luther Toyota in Golden Valley. When I brought the car in, it was warm and the brakes were malfunctioning. Unfortunately, they let the car sit for several hours, the brake fluid cooled, and the mechanic was unable to duplicate the problem.

  The clutch slave cylinder failed at 48,000 miles. On the freeway, I had difficulty shifting into gear and I had cars passing me at high speeds, putting my life and others' lives at risk. This part defect is due to the plastic clutch slave cylinder failing. This common issue is well-documented by numerous other owners, with the part failing before the routine clutch maintenance cycle. My car was inspected by an independent mechanic, who said the lack of clutch pressure is due to the clutch slave cylinder failing. The worst part is that there were no warning lamps or messages before this happened. Toyota is claiming there is no recalls for this part, whic his astounding because the clutch is essential for the 6speed transmission.

  when I use blinker windshield wipers turn on and sometimes when I call or somebody calls my cell phone I can hear them, but they cannot hear me. does not happen all the time, but I was concerned since there was a recall on certain toyota corolla that says a short circuit may develop in the OCS sensor, preventing front passenger air bag from deploying and my son who is a mechanic said both of these could be a problem with the wiring in the column and I thought it may be connected to the same recall as the air bags? the wipers coming on is happening more often these days and that is why I mentioned it to my son who is a mechanic. he will not touch it since it is still under my extended protection but he is concerned about it getting worse since the blinker is attached to the column. as far as using not being heard by callers or when I call I am concerned if I need to call in an emergency the ones I call cannot hear me. as far as when this started I do not remember but I know it's been at least 6 months if not longer, it just seems to be doing it more often lately

Service bulletins

Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.

• 11011642Some technicians may report an engine oil leak from the Engine Oil Level Sensor area
• 11007455Some 2005 2024 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines. This Service Bulletin is to provide a general overview and direction for the odor remediation process.
• 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.

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.

• 11003649The 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. While Toyota paint quality, durability, and resistance to environmental factors is continuously being improved, it remains the responsibility of the dealer to protect and maintain the vehicles paint finish from the time of arrival at the dealership until retail delivery to the customer.
