Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Toyota Corolla Owner Comments

problem #3

Corolla 4-cyl

  • Automatic transmission
  • 35,000 miles


I currently drive a 2003 Corolla and the belt squeak a lot. I work at Toyota myself and I know that every Toyota Corolla belt squeaks. It's not due to the fact on the drive belt but the belt tensioner. I was told by the service advisor that only people that are under the warranty will be replace but that's a outrage. Toyota already knew that the belt tensioner was a bad design and they made a new version to replace the 1st design. I spent 140 bucks to buy the part and the squeak weak away. Every 9th generation Corolla should have a recall on this belt tensioner thing because my car was slipping and losing horsepower. I kept the old part in case you want me to ship it to you. I hope this problem will be resolved.

Automatic tensioner failed. Bearing makes terrible squeaking sound when cold. Getting worse as months go by. Also worse in cold, wet weather. Brought car to dealer. They said it's not covered in basic warranty. Didn't get extended warranty. Is this right" seems like a defective part. Seems like it should be covered under drive train warranty. Have seen same problem with 2 other corrolla's from similar years. Why doesn't Toyota replace this part as part of regular warranty"
