“My 2006 Toyota Prius I just bought recently is having intermittent headlight problems were the headlights frequently turn off while driving at night. So far turning them off on and on again works, but it can be a safety hazard going down the highway. What can be done about this?”

NHTSA complaint #10926423, filed 2016-11, 105,000 miles

“On occasion, when I step on the brake to stop my car (usually when driving under 30 MPH), it feels as though the vehicle tries to accelerate. It seems as though the electronic portion of the vehicle is trying to engage and briefly accelerates when I am trying to stop the vehicle.”

NHTSA complaint #10637135, filed 2014-09, 120,000 miles

“I used a uhual tow dolly to move my car about 30 miles. When I turned on the car to remove it from the dolly the vsc, brake & ABS lights were on. I confirmed that my ABS do not currently work.”

“Almost overnight my Prius dashboard has developed oily patches. If you touch it your finger sticks, if you wipe it the cloth sticks. The dash cannot be cleaned. I worry about the off-gassing and any other health threat from the dash material decomposing, including decomposition inside the AC and heating vents. I worry about the decomposing dash affecting other elements of the car's dash, lighting, computer electrical, and other systems. The only known cure is to replace the dashboard which is an unexpected and unwelcome financial burden.”

NHTSA complaint #11051853, filed 2017-12, 182,869 miles

“Whenever I drive over rough surfaces the brakes won't engage for a few seconds. On several occasions I almost hit the car in front of me or I drove into an intersection and was almost in an accident. I asked a mechanic at the dealership about it and he said that is just how the car is, so nothing was done. It has been an on-going problem since I bought the car in 2006, so the approximate incident date below is irrelevant.”
