2012 Toyota Prius Owner Comments

problem #5

Sep 202014

Prius 4-cyl

  • 9,300 miles


Turning right from a stop sign stop, the car took off in an unintended acceleration and could not be stopped until it hit a curb. The force broke the ball joint of the driver's side wheel causing the wheel to turn approx 45 degrees. The car then skidded about 20 yards and came to a stop with the motor racing. It was a single car crash with no bodily injury.

The contact owns a 2012 Toyota Prius. While driving approximately 45 mph, the vehicle failed to drive in a straight line and drifted to the left and right. The contact had to constantly adjust the steering wheel. The dealer was unable to diagnose the cause of the failure. The manufacturer was notified of the issue. The failure mileage was 10.

On cold mornings the car makes a groaning noise from the rear for aprox a 1/2 block. My dealer was able to verify the problem when I left the car overnight parked outside. They said they are waiting for Toyota to come up with a fix. The car now has just over 10,000 miles but it has been going on for most of the time we have owned it.

When starting to drive the car after is has been sitting for about 3 hours and especially first thing in the morning, the vehicle makes a groaning noise which seems to be coming from the left rear tire area. It lasts for about the first 50 feet and then it stops making the noise. This has happened with temperatures varying between 40 to 75 degrees. When it is really hot in the morning, the noise is not present. The dealer has looked at the vehicle several times and they say that this is a national problem with no solution. I have owned this car for 4 days short of a year with 12,250 miles on it and it does it all the time. This is very frustrating because the car is fine otherwise.

  • 2,400 miles
Repeating several-second groaning or grinding noise heard from rear wheel area upon startup motion. The noise is severe and sounds like low-pitch metal grinding. It's potentially brake related but could be suspension bushings or other components rubbing against one another. It does not sound like typical brake glazing. The noise occurs in all weather conditions and typically after vehicle has been sitting for several hours or overnight. Noise continues for several minutes at stop and start. Noise is loud enough to startle an experienced driver. The absolute severity and indication of the sound is enough to question safe ongoing functionality of braking and/or suspension systems. Multiple reports are documented online at priuschat.com. Toyota does not appear to have a fix or resolution at time of writing, 10/2012. This is for 2012 Prius V model five.
