What 2003 Cadillac Seville owners say
Body & structure
I driving on I-20 west going approximately 70 MPH when right rear tire blew. I stopped in emergency lane and my car wouldn't stay cranked. There were 7 wires that were cut in half. I couldn't crank car because the wires went to fuel system and had to have car towed and someone travel 3 hrs one way to pick me up.
Front frame member collides with ground even on shallow driveways and drainage swales. Front end is much too close to the ground. Inspected several sevilles of this model and found deep gouges in front frame members. Is frame weakened? Dealer and GM rep say damage is normal and nothing can be done. Has happened since first month of ownership. Dealer technician says, "that's normal - they are all gouged and scraped like that."
