Cadillac Seville STS Problems

The Cadillac Seville STS is a luxury-type car manufactured by the Cadillac division of General Motors as a smaller sized top-of-the-line Cadillac. The Seville was lighter; thus more nimble and easier to park. However, just like other cars, the Cadillac Seville can have problems. When owners are faced with problems, questions arise. Read below the questions that have been answered by Experts.

In a Cadillac Seville STS, what is the procedure to remove the rear seat to access the battery
