2013 Cadillac SRX dim Headlights: The latest information I got from calling GM Divisional Office 800-333-4223 was I had to take my SRX to a Cadillac dealer for a diagnostic check of headlights to determined is headlights are bad. I called a local dealer, diagnostic check is $135.00, if a wiring issue is required, a charge of $135.00 an hour is also assessed! IF headlights are determined to be bad and in need of replacement I would have to pay out of pocket for diagnostic check, possible wiring check and cost of new headlights and labor. New headlights and labor approx. $1,800. I was to submit paperwork to GM Divisional Headquarters for a possible reimbursement consideration. I was informed no guarantee on reimbursement only consideration.
