Toyota Camry check engine light comes on

Filed Nov 9, 2026 · Acceleration, Transmission · VA

While driving my 2018 Toyota Camry through Bowers Hill interstate interchange, where multiple major highways merge, my vehicle completely lost the ability to accelerate or maintain speed despite pressing the accelerator pedal. The engine continued to rev and RPMs increased, but the vehicle would not respond with forward acceleration. At the time of the failure I was traveling in an area with heavy, fast moving interstate traffic. I was forced to maneuver across four lanes of moving traffic to reach the far right shoulder while my vehicle was rapidly losing speed and unable to accelerate. This created an extremely dangerous situation because I could not maintain the speed of surrounding traffic or accelerate to safely change lanes. I was at significant risk of being struck by another vehicle. The failure occurred very suddenly with very little time to react. There was no check engine light on and otherwise my car seemed to be operating normally prior to this incident with the exception of a few hard shifts between first and second gear. After the incident, the vehicle was taken to a repair facility. The mechanic informed me that the transmission was not functioning and that a replacement transmission may be necessary. I was also informed that Toyota transmissions were on national backorder and that a service bulletin existed concerning the transmission. The exact cause of the failure has not yet been confirmed. I am reporting this incident because the sudden and complete loss of acceleration at interstate speeds presents a serious safety hazard. Had I been unable to reach the shoulder, or had surrounding traffic been less accommodating, this failure could have resulted in a serious or potentially fatal collision. Me vehicle was purchased from a Toyota dealership used with 42,000 miles and has only 114,000 miles currently. It is available for inspection upon request.

On XXX in [XXX], my well-maintained 2003 Toyota Camry LE (69,019 miles) experienced Sudden Unintended Acceleration (SUA). After stopping with my foot on the brake, I shifted into reverse without touching the accelerator. The engine surged to full throttle, launching backward into a parked car (totaled) and then surging forward uncontrollably around my cul-de-sac while I slammed on the hard, ineffective brake pedal. No Check Engine light was on before or after, and two local mechanics found no stored Diagnostic Trouble Codes (DTCs). I filed Toyota Claim #XXX. On XXX, Toyota’s contractor, Engineering Analysis Associates (EAA), inspected the car and read the EDR at Peruzzi Toyota. On XXX, Toyota denied my claim, finding no mechanical defect and noting an aftermarket floor mat over the OEM mat. Toyota's denial ignores key facts: (1) The aftermarket mat has a heavy nibbed rubber backing, cannot slide, sits well clear of the pedals, and never trapped the accelerator. (2) As proven in Bookout v. Toyota, transient ETCS-i software freezes ("task death") hold the throttle open without setting fault codes and self-clear when turned off, while an open throttle depletes engine vacuum and starves the power brakes. (3) Toyota excluded 2002–2004 Camrys from its Brake Override System software updates. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The 8-speed automatic transmission (UB80E) in this 2019 Toyota Camry SE loses Drive and Reverse once the transmission fluid warms up. When warm, the engine free-revs and the vehicle will not move in Drive or Reverse. When cold, it moves normally. There was no check engine light and no diagnostic trouble codes. The transmission fluid was found burnt. An independent transmission shop, Guaranteed Automotive & Transmission in [XXX], confirmed in writing that the transmission has an internal failure and quoted $8,552.13 for replacement. The failure began within days after the owner took delivery on XXX. The vehicle is now undrivable once warm. This loss of motive power can leave the vehicle stranded in traffic and creates a safety risk. This matches the known defect pattern in Toyota 8-speed transmissions, in which excessive heat in the torque converter burns the fluid and damages the clutch, described in Toyota Technical Service Bulletin T-SB-0008-21 and in current federal class actions naming the 2018-2024 Camry. The vehicle was purchased at auction through RideSafely ([XXX]). I ask the federal safety agency to investigate UB80E transmission failures in 2018-2024 Camrys. The transmission is available for inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This vehicle is experiencing the same problems since 2022 despite multiple attempts to have the vehicle repaired. The fuel pump was part of the recall and it was replaced in 2020. When these problems started in 2022, I was told they need the codes to figure out what’s going on but yet they still couldn’t give me an answer. There was only one code that they addressed which was to replace an engine coil but the car continues breaking down. This most recent time, I fueled the vehicle and it would not start when I was finished. This had happened at least 3 times, all after fueling the vehicle. The car will also shut down while driving, and it is extremely dangerous when power steering fails and there is no acceleration even with the pedal pushed down all the way to the floor in the middle of traffic. I am terrified that I will not only hurt myself but others when this failure causes an accident. One time, the vehicle broke down on a major highway during rush hour, but I was able to get to safety. Other times I had to call a tow because the car was inoperable. The dash lights up with “check engine” and “ics malfunction visit your dealer” each time. I have called corporate and made 15+ trips to get the vehicle diagnosed/fixed but still do not have any answers.

My 2018 Toyota Camry LE went into Limp mode while drive on the highway causing jerking while driving and tons of error codes on the dash, and issues with safety systems shutting off and accelration. After towing to a dealership, dealership gave me the following description of the defect: Coolant is coming through the cylinder walls due to a hairline fracture in the cylinder causing 2 of the 4 cylinders to misfire and coolant to mix with usual contents. We aren't able to identify where the cause of this problem is but it makes the most economical sense to replace the engine with a lower mileage engine and replace the neighboring parts to support the less old engine. I was quoted $8300 approximately. the same vehicle just a few years older are recalled already for the exact same thing - the federal safety agency Recall 20V064000. the federal safety agency Recall states: "The subject vehicles are equipped with a 2.5L 4 Cylinder engine (A25A) and may have been produced with engine blocks containing higher porosity levels. Higher levels of porosity could create cracks in the cooling passages, resulting in coolant leaking internally and/or externally. This may lead to engine noise, engine smoke, warning lights/malfunction indicator illumination, an audible chime sounding, and/or, in some cases, engine overheating and possible internal mechanical engine damage (e.g. seizing of internal engine components). If engine overheating or internal mechanical engine damage were to occur on involved conventional gasoline vehicles, a vehicle stall while driving at higher speeds could occur without prior warning to the driver, increasing the risk of crash."

Check engine light

I brought my 2018 Camry in because of check engine light and was told it was due to the vsv purge valve ($372) and the coolant bypass valve ($1100)- *note I later found out due to my own research that Toyota has an National Warranty Extensions on this part due to failure on 2018-2023 models! After agreeing to replace the costly bypass valve I was called and told the light was still on so they ran ANOTHER diagnostic test that now shows a "new" code that I need a new computer ($1400). The faulty part causes computer damage and I was advised online to speak to the service manager and ask for "consequential damage review" as well as have them cover the part since the warranty covers 10 years or 100k miles. Well of course I was denied because my car is over 100k (what 2018 wouldnt be) and told to reach out to Corporate who also said the same thing. What is interesting is this faulty part extension was just established December 2024 which would not help those of us who were already at the 100k mark when they found this error out. I just paid over $1000 today (not to mention all the times I brought it in before for diagnostic test) and my car runs EXACTLY THE SAME- BAD! AND THE ENGINE LIGHT IS STILL ON!!!!!! I will not give them another $1500 for a new computer. I am now looking for a specialized automotive electronics repair company to repair my computer for likely less than $200! Toyota's service department is a SCAM and I would not recommend buying their cars to anyone going further. My family has 3 Toyotas in our driveway now! I am very disappointed and need someone at Toyota to make this error better!

2020 Toyota Camry XSE, VIN [XXX], 2.5L 4-cylinder A25A-FKS engine, built at Toyota Motor Manufacturing Kentucky (TMMK) during the production window covered by the federal safety agency Recall 20V‑064 (Toyota campaign 20TA04), which addresses porosity in engine castings that can cause internal and external coolant leaks, engine overheating, and possible engine failure. Toyota’s VIN lookup returns this vehicle as not affected by the campaign, but the failure pattern matches the recall defect exactly. Timeline of failures and repair attempts: XXX, at approximately 92,832 miles, Camelback Toyota in Phoenix, AZ (RO XXX). Check engine light active. Diagnosed DTC P268115 (Engine Coolant Bypass Valve Circuit, Short to Battery or Open). Battery also failed load test. Overheating symptom noted on the same repair order. Coolant bypass valve replacement recommended. Following that visit, water pump and thermostat were replaced at Berge Toyota (Mesa/Gilbert, AZ area). Camelback Toyota stated the vehicle was fixed. Vehicle overheated again the next day after being returned as repaired. XXX, at 93,034 miles, Camelback Toyota (RO XXX). Oil and filter change performed under good faith goodwill service, transmission fluid exchange completed. Overheating condition persisted. Vehicle continued to overheat through the summer and into September 2026. Current dealer now recommends head gasket replacement and states that if the head gasket does not resolve the overheating, the engine block is cracked and the engine will need replacement. Dealer describes the engine as “sucking air,” indicating combustion gases entering the cooling system and/or a compromised block-to-head seal. This failure sequence — persistent overheating, multiple failed repair attempts across two Toyota dealers, replacement of water pump, thermostat, and coolant bypass valve without resolution, and dealer conclusion pointing to a cracked engine block — matches the failure mode described in the federal safety agency Rec INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)

Camera / Radar component - yes Camera / Radar unit is available When it failed, the dash lit up with lots of errors: engine check light, anti-skid failure light (even though the system was turned off), rotating errors included: secondary brake system malfunction, pre-collission system malfunction, LDA system malfunction, check engine. I was driving up a 6% hill on a four lane road at 65 MPH with the cruise control active. Was in the left lane passing two slower trucks when the engine just seem to die and the dash lit up with lots of errors. By the time I was able to get to the right lane and off the freeway, I was doing less than 20 MPH. It turns out that when the radar / camera unit failed, the computer put copious confusing errors and put the engine in limp mode. Very dangerous and I'm lucky there wasn't more traffic. When the computer detected the failure should have automatically disabled the cruise control and put out an error message saying it was now disabled. The other junk errors just confused everything. The computer definitely should not have put the engine in limp mode. It was only after I pulled over and had time to digest the errors that I actually figured out what had happened and how to handle the situation. After I pulled off, the center display which had been saying there was a message that would display after I was safely stopped, now had an message indicating I should turn off the cruise control. Problem was I could not determine if the cruise control was active or not because the indicator was blocked by errors, however the engine was still definitely in limp mode. I finally turned the engine off and back on to make sure the cruise control was off. All the rotating errors and error lights were still on, but the engine was now out of limp mode and the car was again drivable.

The fuel pump has a malfunction. The car started jerking and started to accelerate by itself when I was driving it. Yes the problem reproduced. The vehicle is currently under inspection by the manufacturer. Yes there were multiple warning lights including the check engine light.
