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.

2003 Toyota Corolla Owner Comments

problem #1

May 232009

Corolla 1.8L

  • Automatic transmission
  • 117,000 miles


We happily own five Toyota's (4 corollas and a sienna) and just made a deal on a highlander to be received this week, so believe me I have no bias against them. My present problem on our '03 corolla bugs me though. I an not terribly neglectful about checking oil levels, but my son called to tell me that the oil light on the car was flickering and that the car had begun to make a knocking sound. My mechanic now says I need a new engine and that he believes the problem started before the oil got low especially since there was actually a quart and a half left in the pan when I checked it. Looks like a minimum of $2500 worth of trouble on a car that ought to have another 100,000 miles to go. This is why we buy Toyotas, so we don't have to face such expensive problems as these.
