2020 Toyota Camry: check engine light

Filed Sep 9, 2026 · Engine · AZ

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 check engine light illuminated on my 2020 Toyota Camry XSE 2.5L with approximately 132,798 miles. An OBD2 scan revealed fault code P26AE — Engine Coolant Bypass Valve 'B' Control Circuit High. This is a known widespread defect affecting 2018-2022 Toyota Camry, RAV4, and Corolla vehicles equipped with the 2.5L Dynamic Force engine. The plastic valve casing is prone to cracking, allowing coolant to seep into the electrical connector and corrode the pins, triggering the fault. Toyota has acknowledged this issue through a Customer Support Program offering free replacement on qualifying vehicles, however many owners are still being quoted $900-$1,300 at dealerships. The faulty valve affects the engine coolant flow control system and transmission cooling circuit. Warning light appeared suddenly after a routine fuel fill. Vehicle has not yet been inspected by dealer. Component is available for inspection upon request."

Hesitant and sluggish acceleration caused check engine light and activated limp mode. Code P0087 - fuel rail/system pressure too low. My VIN isn’t included on the major fuel pump recall, but I’m experiencing issue and being told it’s going to cost thousands to repair.

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 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.

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 the federal safety agency to investigate the 2018–2020 Camry transmission problems before more drivers experience unexpected failures in traffic

Started vehicle and went to back up. Car slammed into reverse and disply showed Drive start control malfunction. The service engine light came on. I removed the battery to reset the error message and the following dayi took it to the dealership. They checked it out and told me that they didnt find anything wrong with it since it wasnt displaying a service engine light. So i went home with it. The next day it did it again so i took it back to them while the condition was happening. Which insisted of the error message, serv eng light, gearshift indicator displaying drive and park at the same time. Also the door locks were continually locking and unlocking. They put a new water valve plus a neut switch assy and a new xmission lever in it and told me it was fixed. I picked it up and the next day it did it again. Returned it to them and they said that the new part was possibly bad from Toyota, ordered a new one, put it in and said it was all good now. I picked car up and 9 months later its happening again. Not sure what to do. Please help

On December 31, 2001, I was driving 2020 Toyota Camry LE at 20mph and the engine stalled. I kept pressing the gas but my vehicle wouldn't go. The check engine light was also on so we took it to a local shop where they mentioned the Toyota fuel pump recall. We then took it to a local Toyota dealer where they said my specific Camry was not included in the recall and I had to pay $1, 655.69 for a new fuel pump to be installed. My car exhibited the same systems as described in the fuel pump recall therefore I believe my car should be included in the recall and I should be reimbursed.
