2000 Cadillac SLS Engine problems

Good morning;i had purchased a 2000 cadillac seville(sls)used and the car shut off as I was driving on a major highway. The instrument panel (digital)started flashing engine is hot,vehicle engine must be shut down. The car started loosing power and I was able to steer off to the side of road. I'm not sure if the engine would have overheated and caught fire or not? I returned this vehicle to used car dealer for refund. I was told to take it to a garage and I discovered the radiator cap was leaking. It was replaced....

Tl*the contact owns a 2000 cadillac seville sls. While driving 10 mph, the vehicle stalled then shut off without warning. The contact was able to restart the vehicle. The dealer was unable to duplicate the failure. The current and failure mileages were 70,700.

Engine seals leaked everywhere, dealer had to rebuild engine 1 yr ago, now engine block was reportedly "weeping" so the entire engine needed to be replaced. Only 60000 miles, cadillac did cover most of the costs. *Jb

Consumer stated vehicle would stall intermittently without warning. Vehicle had been checked by a dealer several times, but was unable to determine cause. Problem has existed since vehicle was purchased. Ts. Also due to the engine stalling the power steering, brakes, and all lights had become inoperative. Scc *jb

After my 35,000 mile service the engine began using oil. I have the oil changed every 3,000 miles at the local dealer. This last time I used 4 quats between oil changes. The dealer tells me this in normal for the northstar engine. I find this hard to believe. Please advise.*Ak
