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.

Epica LS 2.5L In Line 6

  • Automatic transmission
  • 6,214 miles


1/ check engine light continually came on. 2/replaced o2 sensors numerous times. 3/replaced throttle body, due to engine revving from idle to 2500 rpm for no apparent reason 4/ engine would stumble and stutter on acceleration at various times then magically clear up. 5/ while driving engine would just shut down. 6/wheel bearing hub assembly, had to be replaced on three wheels. 7/electrical system most lights worked with the exception of headlights remote key-less entry, alarm system and remote trunk opener. Re-wired light system to provide normal and high beam lighting. Repair failed after one year. 8/ Car started to have oil leaks. 9/ GM mechanics did not have the knowledge to properly fix this car. It was major trouble after the first year. drove under these conditions until I could no longer put up with it.
