Vehicle was idling in driveway during strong electrical storm. Lightning appeared to hit a tree nearby. Simultaneously, several dash warning lights came on and stayed on, including anti-lock brake, traction and stability control warnings. Call was made to insurance company and vehicle towed to Cadillac dealership. Service department said cause of the warning light was a bolt near wire to anti-lock brake power control module had worn insulation off, causing failure of power control module. If indeed lightning/power surge did not cause this problem, improperly located bolt or design would seem to be defective.
: the contact stated while driving the vehicle at various speeds between 5 to 50 mph the engine stalled without warning, this incident occurred four times. The vehicle has not been to the dealership to be inspected. The manufacturer has not been alerted. The dealer corrected the problem by replacing the battery and crankshaft sensor. Updated 02/21/06.
