On 09/01/10, we took our 2008 Prius in because there were two times the car didn't stop when we used the brakes. I told the service manager, the car was accelerating on its own. It was scary and I feared an accident. After they worked on the car, I was told that it was the floor mats that interfered with the accelerator pedal. It didn't make sense to me because I had to put my foot under the pedal to raise it up since it was stuck. I was angry they completely ignored the fact the car was accelerating on its own and acted as though the problem was handled. On 03/31/12, w. manchester/hindry, before 2:00 P.M., it had drizzled, I stopped at a light, drove ahead and at a fork in the road I tapped my brakes to slow down on a curve. Instead, the car kept accelerating. I stepped on the brakes but the car did not respond. The car kept gaining speed! I was at least 3 car lengths behind other car, plenty of time to stop but the car accelerated no matter how hard I stepped on the brakes. It was terrifying! I realized I was going to crash and there was nothing I could do to prevent it. I rear ended the Mercedes, the airbags failed to deploy. I had 2 boxes of books in the trunk that hit the back of my seat and knocked down the rear seats from the impact. The car was towed. Damages: $5,988.79. Medical: $25,000. Next month, a cracked pump was discovered at firewall, due to the accident. The black box showed impact was at 35 mph, (35-27) mph, 0.02 sec. Injuries: Concussion, whiplash, back spasms, double-crush injury, ptsd, depression, migraines. I couldn't drive or start physical therapy for 4 mos., until 07/27/12. My therapist worked alot to relax my muscles, I had traction, bought a traction device $400. And 6 mos. Of chiropractic for muscle spasms. 12/08/12, I had a nerve-test, it was abnormal for a double-crush injury. Prescribed xanax for ptsd, anxiety.

2008 Prius headlamps intermittent hid problem. This is a known and common problem with Toyota Prius 2004-2009. No recall for it that I am aware of, however they light will go out randomly. The cost of repair can been extreme. Toyota was sued for this, but did not make an official recall (www.girardgibbs.com/Toyota-Prius/). when driving my lights will go out for no reason. Turn the switch off and back on will sometimes correct the issue, but others times I have to wait a bit and retry. This is a danger and safety issue. I have read where repairs can run from 300 - 1100 per side to repair. In addition, the rear lift gate latch rubber is becoming very sticky. I have again read numerous complaints that it eventually melts and again Toyota has not put a recall in place for this. Lastly the mpg is horrible. In the city I get 27 to 36 randomly changes, there is no stability in the mpg. It is all over the board. I am the only driver. This vehicle was purchased at tustin Toyota in tustin California. They have refused all calls from me. They have not called back after 4 messages and two internet chat messages.

My car had hesitation issues since shortly after I bought it. It would bog down, and almost die in traffic. I would lose speed on the hwy/road & nearly get hit. Previously, the dealer replaced the gas tank because its "bladder" was bad @ 54,057 miles on 08/05/2011. The factory split the cost on this repair (which appears to occur more than they are admitting). The performance improved for a little while, but there has always been funny noises coming from my vehicle and the car would not power on at times. Other times, it would freeze or power off. The maintenance warning lights would come on and then turn off. Infrequently, air would come through the backseat vents like it is supposed to. Frequently, I would smell unusual smells after stopping my car. My car ate up the inside of a new set of tires very quickly despite being properly aligned. The HVAC blower motor was cutting on and off at times and making funny noises. Many times when it would cut off, I could open and slam the hood and the HVAC blower motor would engage, as if there was an electrical short in it. When the HVAC blower motor quit altogether, I took my car to the dealer. The dealer said that the mower had gone out. There was an actual problem with the hv electric water pump as well as a factory recall. Interestingly, the dealer discovered tat the engine motor water pump was also leaking. What a coincidence! now that all of these components have been replaced, my car appears to work normal again like it has not worked since I first bought the car.
