Incident Highway Malfunction Occurs -?" [XXX] While driving at a steady speed on the highway, my 2020 Toyota Camry unexpectedly shifted gears on its own. I did not bump the gear shifter or interact with the controls in any abnormal way. The gear shift occurred without warning or driver input, while the vehicle was in motion. A -??Drive Start Control Malfunction-?? warning appeared on the dashboard at the time of the incident. Vehicle Towed to Toyota Service Center -?" July 11 2025 Following the incident, I brought the car to a Toyota dealership for diagnosis and repair. I spoke with a service advisor named Rebecca, explained the situation, and clearly stated that I did not hit or touch the gear. The vehicle was kept for inspection, repair and I communicatied with Toyota. Vehicle Picked Up -?" July 16, 2025 I picked up my car from the Toyota dealership on Wednesday, July 16, 2025. I had not yet heard back from Toyota about coverage or resolution. I chose to wait for further communication regarding whether they would take responsibility for the malfunction. Toyota Corporate Follow-Up Call -?" July 23, 2025 On Tuesday, July 23, 2025, Toyota corporate called to inform me that the repair would not be covered, citing that the vehicle is out of warranty. What disturbed me most was that the representative claimed I had told Rebecca that I might have -??bumped the gear, -?? which is completely false. I made it clear from the beginning that I never touched the gear shifter, and that the malfunction occurred while I was driving normally. This false statement was either a miscommunication or a lie -?" and it minimizes the seriousness of a potential safety defect. Response to Toyota-??s Misrepresentation -?" July 23, 2025 During the call, I told Toyota that misrepresenting my account was unacceptable and dangerous. If Toyota is aware that this vehicle model may experience uncommanded gear changes while in motion and fails to report.

This vehicle, and models with the same throttle body and air filter/air duct assembly have an issue. Where plastic parts from the vacuum box attached to the air duct come loose and get stuck in the throttle body. Causing the engine to rev up then die. I have dealt with this same issue twice in the last three weeks. Thank you for your time.

- Yuma, AZ, USA

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

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

I had a feeling sick while driving my car. I placed a smoke and carbon monoxide detector in the cabin. The detector went off. I tried different things windows up windows down, recuperate open and close and detector alarmed. I brought my car to Doggett Toyota they found a leak in engine that was running to exhaust. I paid for $117 for estimate and $337 for part. The service department is pressing me to let them use my carbon monoxide detector. I refuse. When I went pick up the car fumes plus soap smell is still in the car. Detector still alarm 229ppm.They only offer to rent a ccar which I cannot drive because of health reasons. Other 2020 are carmys are recalled because oil leak and possibly damage to engine block. I requested my car be examined for the same problems as recall. The service department says I need ask corporate to send there own mechanic and I pay for it. Hours of run around miscommunication. That car is not safe to drive. Dealership doesn't have carbon monoxide detector or means to detect the smoke in the cabin. Service members all over the place, texting on cell phone, walking away while on phone with corporate etc.

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.

- Haymarket, VA, USA

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.

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.
