“The vehicle I believe has an ECM (engine control module) problem. Since the first incident where the vehicle wanted to shut off at a stop light, the vehicle erratic RPM fluctuation when the vehicle is at a stop or hesitates when taking off. Toyota has done a recall on some of the 2005 thru 2008 models and I believe this model should be included since it uses the same ECM and has the same engine as the other models”

“My 2004 Toyota corrolla seems to be steering improperly. Upon turning the steering wheel to a straight position the whole car seems to swerve and become almost uncontrollable. I have just barely avoided serveral accidents and in wet condtions the problem is worse. I replaced the tires and had them check the alignment on the vehicle and it still continues to be an issue. …”

“I was driving at 70 MPH on the interstate when the car stalled out. We were able to pull to the side of the road luckily. It did start again but stalled again if I went over 40 MPH. I had replaced the transmission the week before and had a transmission place check it out. They said the transmission is fine and that the error code is for the ECM. I had taken the care back to my transmission place (certified transmission in bellevue ne.) and he had the same answer for me. I attempted to work with Toyota on this through their customer complaint dept. …”

“Foul egg/sulfur smell while car is operating. Smell is noticeable in the interior and exterior of car. At times, this smell is so strong that I begin to feel ill. Returned to dealer. Dealer instructed me to try different gasolines. This did not work. Returned to dealer. Repeatedly spoke with service manager, etc. The suggestion to change gasoline was all the dealer could offer. This has not worked and I'm concerned that the sulfur smell may be causing a health problem.”

NHTSA complaint #10054665, filed 2004-01, 111 miles

“My 2004 Toyota Corolla suddenly had engine problems while driving, making a horrible metallic clanking as the car stalled. After having it towed to the nearest repair facility, the diagnosis was that pieces of the engine literally broke apart as if the metal was fatigued. The mechanic could not explain how this happened with only 117,000 miles on the car. It took over a month to find a used engine and scrape together the money needed for repairs. The entire engine was replaced, for a total of $2500. I was also forced to rent a car during this time, and the car rental amount is around $600.”
