NHTSA complaint #11092060, filed 2018-05, 131,000 miles

“My 2001 Toyota Corolla le with about 68,000 miles, my check engine light came on. I had my mechanic run the obd code, which returned the code of p0446 (evaporative emission control system vent control circuit). My mechanic determined the problem was with the charcoal cannister system that controls the emissions of the Corolla. When I was reading on here I found several people who have the same problem and I want this resolved to no expense to me. I don't have the money it will take to fix this problem.”

“I purchased a used vehicle from keyes Toyota one year ago. It was advertised certified, however when I bought the car they would not honor it. I have been back and forth to the dealership with repairs. Recently the check engine light came on and I spent over $700 replacing the 02 sensors and flushing my brakes. This did not fix the problem and I have to spend another $4-$500 replacing the air flow meter. The mechanic told me that these problem should not be happening to such a young car.”

“We have a 2001 Toyota Corolla that we purchased in july 2000 from don mcgill Toyota in houston. In nov 2008 we noticed that the check engine light would come on every month and so I took the car to autozone for a free diagnostic test each time with the result showing that the car has an electric short circuit problem. This is a defect in the timing chain and a part called a cam. To fix the problem it would cost me around 800 dollars. I reported the problem to the dealer don mcgill in houston and they simply ignored me. I then called up Toyota in california and they too ignored me. …”
