While driving at about 40mph on a city street I complete lost steering, brakes and vehicle control. I suddenly started severely swerving/ spinning. I suddenly had no control over the vehicle. The vehicle threw a bunch of codes at once including: anti-lock brakes malfunction, pre-collision system malfunction, secondary collision brake system malfunction, braking power low, parking brake malfunction. I tried to turn off and restart the car and it did not reset any codes. I have brand new tires on the vehicle and just had an oil change and check up two weeks ago. There was no reason for this to happen other than a complete and sudden safety failure of apparently multiple systems. Vehicle is currently being inspected by local Toyota dealer.
Pre-collision system malfunction, hybrid system malfunction, awd system malfunction suddenly when restarting the vehicle. Towed to Toyota of downtown la dealership. Toyota of downtown la service tells me that the cpu on my relative new Sienna 2022 was fried from jump start when Sienna starting-battery was low. It was done by a aaa professional, I doubt that is the reason for the fried cpu. I believe Toyota engineers would not design/allow the cpu vulnerable to being fried from a jump start. This is a horrific design flaw if it is this way. This happens now, just 6 months after the 3 year warranty coverage. Toyota of downtown la service is telling me it is going to cost me $2900 to replace this cpu. I find this unacceptable.
When pulling out of a parking lot, the accelerator disables leaving the car unable to move in the middle of the rode for a few seconds. The happens intermittently and usually when there is traffic going both ways in the area. This has happened several times but has not been replicated with a dealership employee during test drive. After the accelerator disables, it will enable after a few seconds. It has left me sitting in the road with cars honking at me. Van is currently in the shop. Brake pedal was not deployed at the same time of acceleration.
This hybrid le model brake system is very poor. If we press the break pedal it stops 5-10 meter far. Urgently need for recall and rectify this major issue to avoid more accidents and property damage to others on the road .
I got the software recall fix last week. Today is the first time I have had any issues. 2 time today the emergency braking activated. First time I was leaving mcdonald’s parking lot. I waited for a car to pass then I took off to get on the road. The emergency braking system activated leaving me halfway in the parking lot and part way in the road. I thought that was weird. The a few minutes later I arrived at home and started backing into the driveway like I always do. As I was backing into the driveway a car started to pass on the road in front of me. The car emergency braking system activated leaving me part way in the road and driveway was the car passed. I have saved the ring camera footage of me arriving home in case it is needed.
