Example complaints

“On dec 2, 2020 while driving on the freeway at about 45-50 MPH our sunroof exploded causing us to get to the side of the road. The shade was closed which saved us from exploding glass. There were no road hazards, no issues other than a spontaneous exploding of our sunroof. The orlando police dept was summoned and the roadrangers stopped to assist us. I took the car directly to the Toyota dealership in clermont, fl and they repaired the glass at no charge but told me had the car not been under manufacturer warranty I would have been responsible for the cost of replacement. …”

NHTSA complaint #11397301, filed 2021-02, 6,800 miles

“The gear would shift either from 'drive to neutral' or 'reverse to neutral' this happened more than 10 times when I had my sister, mother, and father in the car. 1) it happened when I was pulling out of the garage (about 20 degree angel) going up the hill. I went to pick them up, all 3 pf them went in. I had my foot on the brake and gear on drive, when I let go of the brake the gear shifted automatically on neutral. After, 3 tries, the car finally was able to go forward without struggle. 2) I was trying to back in one of the spot (flat ground), foot on the brake, gear on reversed. …”

“Back up alarm too loud, this is a safety issue. Fact it is so loud you can not hear the rear cross-traffic alert or any person outside the car yelling. Toyota needs to either develop a method so the owner can adjust the backup alarm volume or have the dealer turn down the volume free of charge.”

NHTSA complaint #11103383, filed 2018-06, 590 miles

“Connect the phone to stereo, activate device assistant, phone call or play audio from the device through stereo. The stereo will reboot. This has occurred a number of times during the first couple weeks of ownership. Doesn't matter if vehicle is in motion or not.”
