Engine And Engine Cooling Problems of Toyota Camry - part 1

While driving the car just shut-off in the middle of the road. If you tried to restart the car it would turn on rev the engine and shut off. The dash display displayed a message " precollision system malfunction" and "secondary brake collision malfunction". Safety wise if this had happened on the highway could have been very dangerous or worse. The car was inoperable and required a tow truck. Luckily we were not on a very busy road during the incident. The problem has been replicated and is currently being tested at joe meyers Toyota in houston, texas. When the message displayed on the dash, check engine light came on as well as the brake light on the dash.

I am reporting a safety-related transmission failure in my 2019 Toyota. The vehicle suddenly lost the ability to drive forward without any warning. There were no check engine lights, warning lights, or alerts before or during the failure. The vehicle would only go in reverse and became completely undrivable. At the time of the failure, my children and my elderly mother were in the vehicle, creating a serious safety risk. Had this occurred in traffic or at an intersection, it could have resulted in an accident. After the failure, I contacted over 30 transmission shops and mechanics, and none are willing to rebuild or repair the transmission due to known and recurring issues with this Toyota transmission model. I contacted Toyota directly and was provided a repair estimate of approximately $8,000, which is unreasonable for a 2019 vehicle and makes repair financially impossible. The vehicle was towed and remains undrivable. I am currently paying $30 per day for a rental vehicle, causing financial hardship. I am submitting this complaint so this issue is documented as a potential safety defect.

While driving home from work , on a major highway, multiple warning lights came on my dashboard and my car would not accelarate. I immediately pulled over and shut the car off, turned it back on and the car was again drivable, however all the lights were on. I went directly to my mechanic and dropped the car off, for further inspection. The next day I was informed that the error code came up as slippage and he recommended replacing the transmission. The car only has around 130,000 miles on it. I have read that there are class action suits against Toyota, and my car make and model are in the group. However I can not find an active class action suit to join, as I just want my car fixed and should not have to pay for it, especially if Toyota knew this transmission was faulty.

My 2025 Toyota Camry xse (hybrid) is subject to an open safety recall issued December 16, 2025. The recall involves a serious safety risk, and I was advised by the dealership not to drive the vehicle. At the time of the recall, the vehicle was approximately two months old with about 1,500 miles and in like-new condition. Because there is currently no available remedy, I was required to leave the vehicle stored at the dealership. I have been without use of my own vehicle since January 6, 2026 and am using a loaner vehicle solely due to the safety recall, not by choice. Toyota has stated a fix may not be available until at least q1 2026, with no defined repair timeline, and customers are being told to wait without interim mitigation. I am concerned about the inability to safely operate my vehicle and the long-term impact of extended storage on a nearly new hybrid vehicle, including hybrid battery health, fuel and fluid systems, seals, tires, and interior and exterior materials. Prior to the recall, the vehicle was routinely garaged and properly maintained, and extended outdoor storage due to the recall introduces risk of premature wear unrelated to normal ownership use. While the dealership has indicated the vehicle may be started periodically, this does not replace normal driving and ownership use. In addition to loss of use, I am required to maintain a $300 monthly loaner vehicle deposit while my vehicle remains unusable due to the recall. Toyota customer service has stated they cannot escalate or provide assistance and are instructed to close cases without resolution, creating ongoing financial burden through no fault of my own. Toyota has acknowledged similar recalls on other models lasting extended periods, yet no interim remedy, mitigation plan, or customer relief is offered here. I believe this raises concerns regarding recall remedy timeliness, consumer safety, and loss of use.

Known by manufacturer. There is a faulty coolant bypass valve that they are forcing customers to pay out of pocket for repairs totaling over $700.

On multiple occasions, when I accelerate — even lightly — the transmission of my 2019 Toyota Camry emits a persistent whining noise. The noise appears as I press the accelerator and increases in pitch and volume as I continue accelerating. As soon as I ease off the accelerator, the whining stops immediately. This behavior happens during normal driving — not under extreme conditions or aggressive driving — and regardless of speed (both city and highway conditions). This whining noise is not a normal transmission behavior for a properly functioning vehicle. I believe this indicates a possible defect or problem with the transmission (or transmission-related components) rather than wear-and-tear due to high mileage or neglect, because: •the vehicle has been regularly maintained (oil changes, scheduled maintenance, etc. ). •I have not abused the transmission, used it for towing, nor driven in severe off-road conditions. •the noise occurs under normal acceleration and is reproducible. I am concerned for my safety and the safety of others, because a failing transmission — or a transmission with design/manufacturing defect — could lead to unexpected shifting issues, loss of power, or other mechanical failure while driving. According to a safety-watchdog summary of NHTSA data, there are 338 complaints submitted to NHTSA for 2019 Toyota Camry models.

The vehicle has experienced ongoing engine misfire issues while driving. The check engine light illuminated, and diagnostic testing identified a cylinder misfire (p0302). The vehicle shakes, runs rough, and has reduced power, especially during acceleration. These symptoms create a safety concern, as the loss of power and engine instability could affect the ability to safely merge, accelerate, or maintain speed in traffic. The issue has been confirmed by diagnostic scans performed by an independent service center. The problem appears to be persistent and not consistent with normal wear for a vehicle of this age and mileage. No collision has occurred, but the condition poses an ongoing safety risk while operating the vehicle. The issue has not yet been resolved by the manufacturer.

Car stalled while driving and needed to be towed to dealership. Dealership confirmed that there was coolant intrusion into the engine that clogged the fuel injector causing the car to stall while driving. Dealership informed us that car will need a new engine and transmission because of the coolant intrusion. The car stalled while driving and could have led to an accident or loss of life depending on where the car stalled and when. This coolant intrusion has been confirmed by the dealership and shown to us via video they took. The vehicle has only been inspected by the dealership and we called Toyota corp to have then review this as a safety issue. They informed us the call stalling was not a safety issue. Unknown on confirmed symptoms prior.

My fuel line came out while I was driving and almost cause my car to catch fire. Which caused my check engine light and other sensors to come on. After further inspections my vehicle indicated my fuel line/hose caused my engine to enter into limp mode explaining on my dash board as reduce engine power.

It’s reading the lda warning lights, secondary collision break malfunction, pre collision break malfunction, check engine light. Car is misfiring and could possibly cut off in mid traffic. Dealer said that the motor has a cracked head gasket. There were no problems prior to these issues.

My 2020 Toyota Camry se suffered a sudden and premature transmission failure at only 114,000 miles. I am a college student and I cannot afford a major repair like this on top of my monthly car payment. The car began showing hesitation and sluggish acceleration on cold starts for a few months, but then suddenly went into limp mode with the check engine and traction control lights on. The screen displayed a warning saying ‘malfunction in the electronic control of the engine/throttle/transmission. ’ the vehicle became unsafe to drive because it would barely accelerate. If this had happened while I was merging onto a highway, it could have caused an accident. Lakeland Toyota told me the transmission has ‘internal failure’ and quoted me over $8,000 for a replacement. They did not provide detailed diagnostic codes or open the transmission to confirm the mechanical failure — they just saw a code and declared it dead. As a student with limited income, this puts me in a terrible financial situation. I still owe monthly payments on this car and now cannot even drive it. After researching online, I learned that many 2018–2020 Camry owners are experiencing similar transmission problems (ua80/ua80e), including hesitation, shuddering, harsh shifting, and early failure. Some owners have reported full transmission failure under 100k miles. There is even a public petition documenting these issues. This appears to be a pattern, not an isolated case. A transmission should not fail this early on a Toyota, and this sudden loss of power poses a serious safety risk. The vehicle is currently at a transmission specialist for a second opinion, but this may become a widespread issue affecting thousands of Camry owners. I am asking NHTSA to investigate the 2018–2020 Camry transmission problems before more drivers experience unexpected failures in traffic.

The vehicle illuminated the malfunction indicator lamp (mil) and stored dtc p26cb71 – electric water pump speed stuck. The dealer confirmed the electric coolant pump actuator is mechanically stuck and requires replacement at a quoted cost of $1,257. 81. Toyota official TSB-0323-17 (published December 8, 2017) explicitly states that this exact repair for dtc p26cb71 is covered under the Toyota federal emission warranty for 96 months or 80,000 miles from the vehicle’s in-service date. Despite the vehicle being well within both time and mileage limits, the dealer and epa both refuse to honor Toyota’s own published 8-year federal emissions warranty, violating 40 cfr §85. 2107(a) which mandates that the manufacturer “shall repair or replace” any covered failed emission-related part at no cost to the owner. The failed electric water pump is an emission-related component because its malfunction triggers an obd-ii emissions dtc and can cause elevated emissions due to improper engine temperature control. The part remains installed in the vehicle and is available for inspection. No warning symptoms appeared prior to the mil illumination.

The contact owns a 2023 Toyota Camry. The contact stated that while driving at various speeds, the vehicle was hesitating and shuddering, and the check engine warning light was illuminated. The vehicle was taken to the local dealer, who diagnosed the vehicle with a transmission fault and that the transmission needed to be replaced. The contact was informed that the transmission failure was caused by a failure with the valve body and pressure solenoid. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 67,000.

I am reporting a serious safety hazard involving a 2010 Toyota Camry purchased from GA carz 4 less, llc through the govdeals. Com platform. The seller provided no disclosures of mechanical issues. Immediately upon receiving the vehicle, it exhibited violent engine knocking, shaking, heavy oil leakage, and repeated engine shutdowns. Two certified mechanics inspected the vehicle and confirmed that the engine has catastrophic internal damage involving camshaft timing system failure and severe internal wear. Both mechanics stated that attempting to operate the vehicle at highway speeds could have caused the engine to explode due to internal failure and pressure spikes. This was an alarming and dangerous finding, especially since the vehicle was advertised without any safety warnings or disclosures. Additionally, the carfax mileage in March 2025 was 193,653 miles, but the vehicle delivered to me showed over 208,000 miles—an undisclosed increase of more than 18,000 miles. This raises potential concerns regarding sustained driving after the auction despite severe mechanical issues. The seller listed the vehicle twice before selling it, suggesting possible prior knowledge of the engine condition. I later found numerous online complaints reporting similar instances of this dealership selling vehicles with severe undisclosed defects, indicating a broader safety problem affecting multiple consumers. The condition of this engine creates a risk of sudden shutdown, engine seizure, explosion, fire, and loss of vehicle control, which could cause serious injury or death. I am requesting that NHTSA review this matter, investigate the safety risks associated with these undisclosed engine defects, and determine whether this dealership’s practices pose a danger to the public. This complaint is being filed to prevent potential harm to future buyers and to document a serious safety hazard that I experienced firsthand.

2018 Toyota Camry at times vehicle engine will run under engine temperature, and other times, vehicle will overheat. This is intermittent issue and is not all the time. When vehicle is shut down. For 5, 10 minutes, it seems to work fine again for a week or two, and then starts to act up again. Toyota is aware of this issue with a defective electronic water valve part that control the flow of water into the engine. Toyota did send notice out should this issue happen they will do a free voluntary repair to replace that defective electronic water valve even after the original initial warranty expires. Bringing to dealer to check and I will update after the fix was made that is suppose to fix this over heating issue with engine code reading p26cb. If you have same issue with vehicle years in question with code p26cb you might want to contact Toyota. This is a safety issue should engine start to overheat while driving.

I am reporting a safety-related issue involving the ecm / torque converter on my 2012 Toyota Camry. This issue can cause loss of power, hesitation, or stalling which presents a serious safety concern while driving. The issue impacts drivability and can result in sudden loss of acceleration or engine stalling, especially at higher speeds or during merging. This creates an increased risk of collision for myself, passengers, and surrounding vehicles. I have experienced some scary occurrences with shuddering at high speeds, hesitation while near other innocent vehicles and stalling. I was never notified by Toyota about this recall or service campaign while it was active. I maintain current registration information and would have had the issue addressed immediately. Toyota acknowledged the campaign but refused support due to expiration, despite my lack of notice. I contacted Toyota and was instructed to file a complaint with NHTSA. Toyota declined to repair the issue under goodwill or policy exception. I am requesting that NHTSA investigate whether this defect should have been classified as a safety recall and whether consumers were properly notified. Sudden loss of power or stalling presents a significant safety risk and may warrant additional remedies or extension of the campaign for affected owners who were not notified.

I went a few months ago to Toyota to get an air flow valve replaced from a safety campaign for Toyota. My car engine light came on. Afterwards it never went off. My car shuts off after getting gas . Car doesn’t start for 20 mins. Coolant is leaking . Car idling high as if the valve that was replaced was faulty. The car acts like it’s gonna shut off. I take good care of my car & several people have the same complaints please investigate this. I don’t have the money to replace something that isn’t my fault.

Poor acceleration and lose of transmission control …. Complete safety hazard and the car has a failure to lose power while driving…. . A humming noise and the car jerks while shifting gears.

2019 Camry se would not accelerate and rpm’s would escalate without making car move. Car has had complete maintenance on a regular basis. There have been no prior lights on or alerts until my son’s car stalled in traffic almost leading to side collision. Once it was plugged up to computer shows faulty transmission (complete transmission failure) and engine coolant bypass valve which I know has a tbs report on yet my local dealership refuses to do anything with it unless they charge me to hook up to their computer first and deny any issues with this car. I have read hundred of others with the same complaint and numerous lawsuits yet Toyota refuses to recall and fix the faulty transmissions in these vehicles. Something needs to be done before someone is killed, as my son could have been when his car stalled in middle of traffic and transmission failed with no prior warnings.

I paid off my var in June. By the ed of August my cars engine started going bad out of no where. Started with oil and coolant mixing into the engine and then transmission started whining. Long story short I had to get both replaced. Oh yea my car only has 56k miles. Can you guys explain or give me any ideas on how this happened?.
