2002 Cadillac Seville STS 4dr Sedan (4.6L 8cyl 4A)
I have had nothing but problems from the moment I drove my Cadillac Seville STS off the lot. My repair folder is over 3" thick - including continual vibration in steering at various speeds and reverbration in entire car and tie rods that were replaced numerous times. There is service bulletin out there - but dealers won't disclose this. I would NEVER recommend the Seville to anyone.
Be honest and let customers know of "secret" service bulletins.
