  • 11,557 miles


Purchased a 2009 Toyota Corolla on Jan. 31, 2009. Immediately noticed "unwanted acceleration", the car wanted to go when stopped unless the brake was applied hard and did not slow down immediately when foot was taken off the gas pedal. Gas pedal did not always come all the way up when foot taken off, but would pop up if brakes applied hard. Cruise control did not work properly. Mentioned concern several times to Toyota service dept. They told me that what I was describing was normal for those cars. The car was in an accident on 12/22/09. Hit another car from behind. I think that the "not slowing down immediately when foot taken off gas pedal" was a contributing factor to the accident. There were no injuries but the car was badly damaged. Toyota sent recall notice but said VIN#'s beginning in J not affected. Our car begins with J. recently send letters to Toyota and waiting for reply.

In the past year, I have experienced sudden ┐jerks┐ during acceleration on at least two occasions, and had the vehicle inspected twice, in August 2009 and in December 2009. In both instances, Toyota mechanics advised they could not identify a problem. Additionally, throughout the past year, I have experienced noticeable problems with the electrical system, which raise concerns about the overall integrity of the electrics. There has been very frequent loss of power to the power door locks and manufacturer's radio. During the inspections, Toyota mechanics could not identify a problem in this area either.

  • 21,837 miles


The contact owns a 2009 Toyota Corolla. While driving approximately 5 mph out of her driveway, suddenly, the "malfunction" indicator lamp illuminated on the instrument panel. The rear end of the vehicle began to vibrate. The warning indicator light remained illuminated until the engine was turned off. The contact was able to continue driving normally. The vehicle was taken to an authorized dealer for inspection. The technician stated that the failure was contributed to rodents eating the soy based wiring. The vehicle was repaired for the identical failure on three separate occasions. The failure continues with no resolutions. The failure mileage was 21,837 and the current mileage was 22,200.

  • Automatic transmission
  • 32,000 miles
2009 Toyota Corolla, "S" automatic transmission. The problem was initially identified by me when my car would not catch while on a slope in drive. The transmission would roll back. The dealership said this was normal due to a loss of pressure, however it would do it even if I barley stopped on a gradual incline for a few seconds. This has caused me to roll back unless I had one foot on the brake and one foot on the gas while to keep me steady to start. This happened at from the time I purchased the car. Recently, I my engine has been running really rough and winding at a high pitch while driving. It now intermittently goes between gears and downshifts automatically into gears that are not appropriate for the speeds traveling. This causes a drastic down speed, and example is I will be on the freeway traveling speeds between 50-65 and it will downshift and reduce my speed to 40 mph or less, then I will try to accelerate and it will redline out, as if I am in neutral and I will have no control to regain speed until it automatically pushes itself back into gear, and then increases my speed at a rapid pace, without me putting my foot on the gas. At this point, I am required to place my foot on the brake to control my speeds. The dealership has taken my car back twice and claimed to have fixed it twice based on the reads, but I have had the same problem. The reads on the computer will say that it is an electrical malfunction... however they can not identify where the malfunction is coming from. Parts have not been replaced and no repairs have been made to fix this at this time. Toyota is not assisting with the recall and I am left with lots of shop hours. Thinking about registering for the lemon law about my car, I drive apx. 1000 miles week and my car is not saving, consistent, and is a safety issue since have no control while my car malfunctions. I can only react to what is happening. It also makes a loud clunking sound, and a high winding sound when redlining.
