1999 Cadillac Sts

OUR STS STALLED SEVERAL TIMES, BUT THE SCARIEST WAS ON THE HIGHWAY GOING 65 MPH. THE CAR TOTALLY SHUT OFF, LEAVING THE CAR WITHOUT ANY POWER. WE WERE ABLE TO GUIDE THE CAR TO THE SIDE OF THE HIGHWAY AND THANK GOODNESS IT STARTED AGAIN. ON SEVERAL OTHER OCCASIONS, THE CAR WOULD SHUT OFF AND SOMETIMES WOULDN'T EVEN START UP RIGHT AWAY. THIS WAS VERY FRUSTRATING AND THE UNKNOWING, MADE DRIVING THIS CAR VERY UNPREDICTABLE. EVERY TIME WE BROUGHT THE CAR TO BE CHECKED THEY COULD NOT FIND "ANYTHING". FINALLY, AN INDEPENDENT MECHANIC SUGGESTED PUTTING IN A NEW STARTER AND THIS SOLVED THE PROBLEM. THANK GOODNESS. THE SEVILLE STS IS NOW RUNNING, BUT THE A/C HAS GONE OUT. THE CAR IS TOO OLD TO EVEN FIX AT THIS POINT. *TR

I BOUGHT A 1999 CADILLAC STS FROM A DEALER IN MORGANTOWN, WV. IT WAS A COUPLE OF YEARS OLD. NOW, IT HAS ABOUT 124,000 MILES ON IT. AFTER A FEW TRIPS TO THE DEALERS SERVICE DEPARTMENT RECENTLY, I WAS TOLD THE REASON MY CAR WAS RUNNING ROUGHLY WAS BECAUSE THERE WAS A LEAKING HEAD GASKET. UNFORTUNATELY, THE DEALER SAID, THEY WON'T TRY TO REPAIR IT BECAUSE THEIR EXPERIENCE WITH THE CADILLAC NORTHSTAR ENGINE IS THAT IF THEY TRY TO REMOVE IT, IT STRIPS SOME SORT OF BOLT OR THREAD, RUINING THE ENGINE. I HAVE BEEN IN TOUCH WITH CADILLAC BY TELEPHONE AND BY E-MAIL SEVERAL TIMES TO ASK IF IT IS TRUE THAT THEY HAVE DESIGNED AND SOLD A CAR THAT CAN'T BE REPAIRED. THEY WOULDN'T ANSWER ME DIRECTLY; INSTEAD, THEY SAID MY CAR IS OUT OF WARRANTY AND NO LONGER THEIR RESPONSIBILITY. FINALLY, SOMEONE CONCEDED THAT IT IS TRUE. I AM SHOCKED THAT A COMPANY LIKE CADILLAC CAN DESIGN AND DELIVER A CAR, KNOWING THAT CERTAIN MAJOR PROBLEMS CAN'T BE REPAIRED. *NM

Refinishing Aluminum Wheels This bulletin updates General Motor's position on refinishing aluminum wheels. GM does not endorse any repairs that involve welding, bending, straightening o re-machining. Only cosmetic refinishing of the wheel's coatings, using recommended procedures, is allowed. Evaluating Damage In evaluating damage, it is the GM Dealer's responsibility to inspect the wheel for corrosion, scrapes, gouges, etc. The Dealer must insure that such damage is not deeper than what can be sanded or polished off. The wheel must be inspected for cracks. If cracks are found, discard the wheel. Any wheels with bent rim flanges must not be repaired or refinished. Wheels that have been refinished by an outside company must be returned to the same vehicle. The Dealer must record the wheel ID stamp or the cast date on the wheel in order to assure this requirement. Refer to Refinisher's Responsibility — Outside Company later in this bulletin.
