The Northstar engine until about 2002 had lugbolts that were too short. So it blows a headgasket climbing hills. $3500 to repair with new longer bolts. No old high mileage Northstars ,only dead ones. Engine not considered rebuildable. A Cadillac engine design mistake (30 yr Cad owner)

Worst motor ever. I've spent over 5k at the dealer and now it needed a new engine.

I had an accident with my previous 99 sts. I missed it so much I purchased the exact same car. Its a great car it drives identically to my previous cadillac. which was a suprise because I bought with 115,000 miles. My best advice in keeping a car running well is Change The Oil Every 3,000 miles! I put synthetic in my car and never go past 4,500 miles never. In this car the most expensive repair was a steering rack$500, I put in a bose door speaker $230 worth every penny, and had to replace a motor mount $110 installed. It helps to work for a dealership and get employee price. I burn 3/4 of a pint of oil between oil changes not bad. although these cars are known for drinking oil.

I bought mine new in 1999. 10 years later it's still going strong. 142,000 miles on it now. It had a few issues in the first 50,000 miles, all of which were covered under warranty, a leak in the trunk, the seat heater broke and a leak in the sun roof. right now the only issue is it needs a quart of oil between oil changes and the ABS needs repair.

I got my STS when it had 95,000 miles on it. I paid $9,500 and it was in great condition. I had some concerns about it breaking down and being expensive to repair. I put 20,000 miles on it this year and I have only had small problem. It needed new spark plugs and wires at 10,500 and a new water pump at 114,000. I had a small problem with the heater core getting clogged up, but I used some cleaner and it was fine. I keep blowing the speakers listening in music very loud, but I replace this with great after market speakers. It rides great and performs wonderfully. I rough idea and oil burning is to be expected. O love this car and I paid pocket change for it. Everyone thinks I spent $30,000
