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 Tacoma Owner Comments

problem #1

Jul 142005

Tacoma 4-cyl

  • Automatic transmission
  • 54,000 miles


Intermittent check engine light and rough idle - 2003 Toyota Tacoma 2.7L auto, double cab, 55K miles check engine light came on. Took vehicle to local chain shop who diagnosed error code PO511 - idle air control valve (iacv). Toyota parts department prices this part at $226 and service manager indicated $249 for labor (not including tax). Vehicle currently has 55K miles on it and "engine" should be covered by 6 yr/60K mile powertrain warranty. Took vehicle to dealer (to have other recalls corrected) who indicated a $90 fee was required just to diagnose check engine light. Toyota customer service indicated the iacv was only covered to 3yr/36K and that I should pay dealer fee and seek "factory assistance" for any costs to repair. I contend that this type of a part - not serviceable/maintainable by the customer, should be guaranteed against failure for more than ~50K miles and repair should be covered by manufacturer.
