“I have a 2008 Toyota Avalon that I had only 4 months prior to the accident. The car appeared to be in excellent condition until my husband took it to the delta sonic carwash to have it clean.

NHTSA complaint #10311238, filed 2010-02, 5,278 miles“06/12/10-I started my car as usual with my brake depressed and attempted to put the car in reverse---it wiggled but would not move from the park position to the reverse position. After numerous attempts I was able to do so and take care of my shopping trip. Upon completing my errands the same event occurred with the shift lever once again.

NHTSA complaint #10336000, filed 2010-06, 31,377 miles“Cannot express my complete and utter disgust with my recent experience and overall experience since buying my 2008 Toyota Avalon. I expected quality from the product as the Toyota website states..however, since I have had this vehicle the 300 dollar a piece drivers side head light blew out along with both high beam lights.

NHTSA complaint #10317854, filed 2010-03, 48,500 miles“My husband got into the car the late afternoon of jan. 17, 2010. Turned the auto on and I thought the engine was exploding. I was inside the house and ran outdoors. Something under the hood was making an extreme loud rattle. If you took an old cow bell and shook it for dear life, you would get an ideal of what I am talking about regarding the sound. The check engine light and the vsc light was on. My husband cut the engine off, checked under the hood and found nothing. I was going to call the dealership to see if they wanted to tow the car in. …”
NHTSA complaint #10307108, filed 2010-02, 12,500 miles“I purchased a used 2008 Toyota Avalon limited from hornburg jaguar dealer in santa monica on 10/29/2009. At home at 8 am, on the clear, cool day of 11/1/2009 I had the car parked in my driveway to install the garage door opener. Wanting to move the car to the street I started the car using the required proceedure for a pushbutton ignition (like on my 2007 Toyota camry hybrid for 2 1/2 years). That is, I stepped on the brake and pushed the ignition button simultaeneously. The car started to move rapidly down my short sloping driveway (7 or 8 feet). …”
