CAMPAIGN: EXHAUST SYSTEM CORROSION (INSTALL NEW KIT)
Subject: EXHAUST SYSTEM CORROSION
Models: 1989-91 Chevrolet & GMC Tracker
TO: ALL GENERAL MOTORS DEALERS:
General Motors of Canada has determined that certain 1989-91 Chevrolet and GMC Trackers may experience a perforation of the two-piece muffler/tailpipe due to corrosion if the vehicle is frequently driven on roads where large amounts of salt are applied during winter weather. Continuing corrosion of a perforated tailpipe can eventually result in the tailpipe becoming completely separated from the rest of the exhaust system. Exhaust gas leakage from a separated tailpipe can cause heat damage to the vehicle's rear floor material and carpeting.
To prevent this condition from occurring, dealers are to install an exhaust heat shield on involved vehicles.
