Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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

“Toyota Prius 2019 can only change its map mode freeway exit inset while driving at 55 MPH. I must take my eyes off the road to find and press the correct buttons on the navigation screen. Seems to be a problem with all generation 4 Prius's. You cannot change it when parked. The picture shows the options when parked.”

“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.”

“A few weeks ago, at around 10pm, when I was driving on the freeway, my car’s engine temperature warning light suddenly on. The next day, I immediately sent my car to the dealer for a check up, the report stated ‘’ coolant reservoir very low. Pressure tested system found exhaust center pipe leaking coolant internally’’. I was surprised by the problem as I only drove this car for around 3.5 years with 70,000 miles, after talking with friends and doing research, I just realized that was problems for many Toyota owners. …”

NHTSA complaint #11516804, filed 2023-04

“Body of car has rust perforation starting from the inside working out. This is on the roof, so water incursion will effect airbags and electrical system. FIrst noticed rust bubbles a few years ago, but did not think much of it. Now two body shops have said roof panel needs to be replaced. This is big stuff!”
