2020 Toyota Camry Engine Problems

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 NHTSA 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 NHTSA Rec INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

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.

This was a recall due to the coolant valve Thursday, my vehicle had went in for the recall I picked up my vehicle Friday morning I checked to make sure the part that they have changed nothing wrong with it or not. When I looked at the part a day after I noticed pink stuff is leaking from around it this was announced by Toyota This is the New part they had just made I’m assuming and it is still leaking I have a 2020 Toyota Camry. With 141,000 miles. And now I am having issues. Toyota needs to redesign this piece or have a further investigation on it.

vehicle will stall out in the middle of driving as if it does not have any fuel. Toyota could not pull the error code a second time replaced a random part and the next month the car continued to stall out.

Low pressure fuel pump defective. Engine dies and/or surges under load at cruise speeds, sometimes dies at idle. Engine shuts down merging onto highway. Occupant(s) could be hit when pulling out into traffic if engine dies. Problem has been reproduced. Dealership said fuel pump is not covered under previous recall, but Toyota has a TSB stating the VIN# is in the TSB range for the above mentioned concerns. No DTC's are set, no messages set.

The coolant bypass valve has failed and my car is at 30,000 miles. This seems like a common problem as I see a lot of other people mention needing this replaced on their Camrys and RAV4s. The dealership said they are replacing all of them on Camry’s, RAV4’s, and Corolla’s

Constant "ENGINE MAINTENANCE REQUIRED" warning. Dealer identified the engine coolant bypass valve as the source of the problem. Replacing the part resolved the issue.

2020 Camry has 34000 miles and the engine maintenance required comes on. The dealer says it is the coolant bypass valve. They will replace it but after looking online there are many reports of this happening to toyotas with low mileage. Coolant can corrode the electric components.

Engine: Fault Code P268115 - Engine Coolant Bypass Valve Control Circuit/Open: Circuit Short To Battery or Open. This is a huge ongoing problem with Toyota vehicles. You can do a simple search and find 100s of people with the same issue. This must be addressed and a recall issued for repair.

Incident: Just driving along when all of a sudden, the car engine turned off and check engine light came on along with warnings about brake system failures, fuels system failures and message to contact your dealer. Any attempts to restart the car failed. The vehicle was a 2020 toyota camry xse with 75000 miles. The vehicle was inoperable. CAUSE: There is a small air intake resonator box that connects to the air flow between the air filter compartment and the throttle. This resonator is made of plastic and the part that connects to the airflow main tube, had cracked and broken off and the broken piece got stuck in the throttle causing the vehicle to become disabled. This part is never touched when performing air filter maintenance and it was determined that over time, it just cracked and eventually broke off. This is a defect in the design and if this had happened at highway speeds could have had serious consequences.

Coolant bypass valve My check engine light turns on when the AC is activated.

Did not happen to this vehicle, but others the same year. I am a tech who has seen multiple failures of the crankshaft position plate which is mounted between the flywheel and crankshaft brake causing engine to shut down while driving due to crank position sensor not receiving signal. I am concerned because my wife drives one which is the vin I gave, that her car may cut off in traffic causing a accident. This part is defective with holes cut around it where the new replacement part is solid.This should be replaced at no cost to customers when vehicle warranty coverage has run out. Information below is for a vehicle that I worked on and have seen 3 others. One resulting in engine & transmission replacement due to excessive damage from plate coming apart. I work for Toyota & don't want my identity shared with them.

Acceleration felt weird when is performed from full stop or moderate speed to a “chase” speed (high revolutions), it doesn’t respond according to the action taken to the gas pedal. Also the crash sensor went off from time to time.

I have owned 5 Toyotas and a Lexus SUV and never had so many problems. This is a 2020 Camry Hybrid with only 20492 miles on it. It has had to be jump-started 3-4 times so far, but now it has a new issue: While on a road trip with my wife thru Utah, the car suddenly shuts down, bells ringing and messages appearing. Cruise control, Lane departure, and Headlight System Failure. This happened on a 2-lane highway with very minimal shoulder. I pulled over as far as I could, but still slightly in the lane. Turned off the ignition and after a minute or so, was able to restart the car. Noted that the sign on the road said "Next Services 129 Miles"! This was on July 11, 2022 at about 3 PM. Once car was restarted, we drove to our destination without further issues, however I would not use Cruise control for fear it would happen again. Got back to California the next day and took it to dealer to investigate the cause. Their conclusion: "Extreme heat caused the warning lights to come on, but history code indicates that the issue resolved itself. The vehicle is operating normally at this time but the system will be affected by high temperatures and direct sunlight"!!! The temperature on the road at the time was 95 degrees. Dealer contacted Toyota's technical assistance hot line to document concern Case #221930394. Per the service department, they called the field rep who said if everything was functioning at this time, then there was no action to be taken. First of all, I am 75 years old and do not expect this from a car with only 20492 miles on it, and especially not from a Toyota. I find the "solution" to be completely foolish - avoid high temperatures and direct sunlight!! Temperatures over 95 degrees and direct sunlight are common in many states. Can someone please get to the bottom of this? I am beginning to think that I bought a lemon. I am also reporting it to NHTSA, as it is a safety issue that must be dealt with. Thank you,
