What 2000 Cadillac STS owners say
Electrical system
Owner complained about the design of the battery storage. The battery is located under the rear passenger seat. The ac- delco battery which was installed by the manufacturer is losing acid through its positive post, causing the battery to leak acid. The acid fumes are toxic and extremely flammable. Owner contacted the manufacturer who was aware, but was not trying to recall these vehicles.
Car stalls with no warning while driving, even at highway speeds. The dealers know that this occurs often on this model, but there is no recall.

2000 STS car stalls while driving or sitting at a stop. I have tried to contact GM with no results,can't even get anyone to return my calls.
