Suspension Sensor faulty, $300+ repair
Stalls for no reason
Theft Deterrent system faulty, $600+ to repair, had to have it towed to dealer
Service Engine soon light goes on after gas fill up and stays on for a few days
Battery Post broke although located under seat. Had to have it towed to dealer. No Explanation from Dealer except to replace...Expensive!
Comfortable, classy looking. Loved the powerful engine but completely unreliable car. Handled beautifully.
My 01 STS I bought new. The only problem I EVER had was the crank sensors (wich caused it to stall), but that wasn't very expensive to fix. Sounds like someone had a bad dealer. But my STS just hit 110,000 miles. These are great cars. Just like any other vehicle you must maintain it. A "broken battery post" sounds like owner neglect. Oh and my battery post never broke.
