problem #3

Regal LX 3.2L

  • Automatic transmission
  • 65,000 miles


No issues with vehicle until approx 65000 miles. Car would shut down with check engine, brake light lit.Would not start. Had towed to dealer no codes on failure and dealer could not duplicate issue but after tow and setting overnight ran fine. Picked up vehicle and second occurrence after 5 miles. Back to dealer; no codes. Dealer felt fuel pump issue and after $600 new fuel pump car operated for approximately one week before it decided to fail again. After letting vehicle set for over 30 minutes; repeated cranking attempts... ignition and was able to get the vehicle home. Complained to dealer and I towed back to their shop. Advised dealer that I discovered that similar issues on web related to mass airflow sensor or crankshaft position sensor. Awaiting to hear that problem could not be duplicated and what they recommend. Why not have a vehicle issue site where we have an accurate accumulation of knowledge over time.

Regal LS 3.8L

  • Automatic transmission
  • 248,000 miles

My car will stall when I am driving and all the dash lights will come on. Sometimes when I try to start it the dash lights will begin to flash as if they are on the blinker flasher and if the starter will turn over, the motor won't start but will buck and spit like it is totally out of timing. Sometimes the starter won't turn over, it is as if there is no power going to it. If I try to start it a few times it will return to normal, it starts and away we go. It has never yet failed to start.

It occurs at various times and seems to go in streaks. It will go for a long time with no problem and then it will have problems continuously for a period of a day or days. I see other people have stated that it is an ignition switch problem. Is this covered under the new GM ignition switch recall?

Regal LS 6

  • Automatic transmission
  • 67,000 miles

This is the Third Buick Regal I have had. The first one gave me no problem. Second one kept stalling and I spent over $2000 trying to fix it. I finally traded it in for this 2003 Buick Regal. I love this car BUT...It has started doing the same thing! It is now at a dealer's repair shop and it is going to cost me a gazillion dollars to fix!!!!!!! How come no one else has had this problem? Why hasn't anyone else complained about it?? Also, my air conditioning has developed a leak and I can't afford to replace it.
