What owners say
While driving my 2026 Toyota Camry LE Hybrid at approximately 10 mph in a parking lot, the vehicle accelerated on its own without any input from me. I applied hard braking to bring the vehicle under control. No collision occurred. The specific component or system that failed is UNKNOWN — I suspect the speed control, powertrain, or electrical throttle system, but this has not yet been diagnosed. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because the vehicle accelerated unexpectedly at low speed in a parking lot, an environment with pedestrians, parked vehicles, and other close-proximity hazards. I had to brake hard to stop it, which could have resulted in a collision with another vehicle, a pedestrian, or a fixed object had I not been able to react in time. The problem has not yet been reproduced or confirmed by a dealer. I reported the incident to Toyota the day after it occurred; Toyota opened case number 260811002989 and scheduled a diagnostic inspection appointment. As of this filing, that inspection has not yet taken place. There were no warning lamps, messages, or other symptoms before or during the incident. The dashboard showed no malfunction indicators at any point.
I had just bought the car from the Dealer and was to drive it back home. I got about 30 miles from the Dealership and the check engine light came on. It stated malfunction in the awd system so now on two wheel drive then it stated start control malfunction and finally hybrid system malfunction. I returned it to the dealership and they said that the first diagnostic stated it was throwing high voltage. Looking on line when I got home I noticed the recall of many Toyota camrys for the loose bolt causing this issue and there is yet to be a fix for it. The manufacturer should take all those cars back so they cannot be sold and cause a risk till they can fix it. It makes a dealership look bad and puts innocent people at risk if they are not aware of the issue.
Saturday may 23 at night my car started showing a message that states “Braking Power Low Stop in a Safe Place See Owner's Manual” I took it to Toyota on Tuesday may 2026 they said it was fine and nothing was wrong even after I said that message kept appearing at least five times each time I was driving the vehicle since Saturday. After they checked it the problem got worse and now it appears 95% of the time I’m driving. Not just that but on may 27 at approximately 9:10 pm my check engine turned on and also system lady took turned on and secondary collision break malfunction turned on. Along side many other warning comes and go but the main ones that stay are the check engine and the braking power low one. I am worried because this all started happening whenever I accelerated even just a little bit and it could end up causing accidents.
