“I bought a brand new 2019 Prius from the dealership that I work at. Only a month later, the pre collision system started become unavailable and the engine started making a loud cranking noise. I took it to Toyota and they told me that the pcs milimetre wave sensor was missing from the car. They also did not want to fix the engine problem or even look into it despite still having warranty left.”
NHTSA complaint #11315905, filed 2020-03, 4,500 miles“Prius stalls in the rain despite not being a recalled model. Pcs sensor is aftermarket, pedestrian warning alert noise is offline, suspension is cracked, engine makes creaking noise at low speed turning. I worked for Toyota as a salesperson and they really took advantage of me.”

The entire dashboard went off (blinders cannot be turn on. No indication of speed, no indication of vehicle level, etc). Anything that's on the dashboard went blank. I turned on and off the new card a few time, but the result was the same. Toyota technician couldn't figure out what went wrong themselves. …”
