1999 Cadillac STS problems

Filed Sep 12, 2014 · Engine · 98,587 miles · KS

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.

Having problems with car keep charge, something is pulling or draining the battery, battery been replaced 3 times and still the same problems sometimes you get in the car and it start other time it won't. I commute 1 hour away from home and this is a problem. I have to keep calling allstate to give me a jump this is ridiculous. Something must be done.

1999 cadillac sevillests. 100,600 miles on odometer. While driving at slow speed (in town) , engine will stop entirely,.- I lose my power steering, brakes and everything else . When I get stopped, engine will start immediately. I'e had the battery checked, and am told all the connections were "fine". A gm dealer recently tuned the engine , and suggested that he replace the wiring" he did so. He did this @ two months before the trouble started. The dealer is out of business. I am afraid to drive the car -- suppose this had occurred while driving 65-70 MPH on the interstate. ??? Please advise me!!! Riving, engine will stop entirely - I lose my power steering, brakes, and everything else. When I get stopped, the engine will start immediately. Have checked battery connection and it checks "fine".

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.

Dt*: the contact stated while driving at various speeds the vehicle stalls without warning resulting in loss of power. Afterwards, the vehicle restarts in less than a minute. The stalling occurs intermittently and has gradually become worse. The vehicle was taken to an independent repair shop for inspection who was unable to determine the cause of the problem.
