1990 Pontiac Grand Prix Engine Problems

Owner-reported complaints naming the engine system, filed with NHTSA

Data refreshed

Engine reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

CAR WOULD GET HORRID GAS MILEAGE, OCCASIONALLY STALL, EXHAUST SMELL UNDER HOOD, BLACK EXHAUST. THE CROSSOVER PIPE FROM EACH EXHAUST MANIFOLD HAS A COMMON CRACKING ON THE BELLOWS AND MUST BE REPLACED, THEY RUN $2500 FROM GM WHICH JUST CRACK AGAIN, OR $425 FOR JEFF M ONE THAT DOESN'T CRACK. THE PIPE CRACKS CAUSE FRESH AIR TO ENTER THE EXHAUST AND THE OXYGEN SENSOR THINKS THE CARS RUNNING RICH, CAUSING HORRIBLE GAS MILEAGE, OIL CONTAMINATION, AND STALLING. THE EXTRA HEAT FROM THE CAR RUNNING RICH CRACKS THE TURBO HOUSING. *NM
