general problems of the 2003 Cadillac STS

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.
