  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…

  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;…
