Subject:
PRODUCT CAMPAIGN 91C29 - EXHAUST SYSTEM CORROSION

Model and Year:
1989-91 GEO TRACKER


To: All Chevrolet/Geo Dealers

General Motors has determined that certain 1989-91 Geo 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.
