CarComplaints instead ranks 2003 as its worst year, illustrating why neither ranking should be treated as a definitive reliability verdict. Use these year-level results to guide questions and inspections—not to decide whether a particular decades-old car is sound.
Which Pontiac Grand Am years look best in the complaint data?
ForCar analyzed 3,410 NHTSA owner complaints for 1995–2005 Grand Ams and divided complaint counts by distinct first-eleven-character VIN production runs. Its figures put 1998 at the lowest reported rate, with 1997 and 1995 next. This is a complaint-based comparison, not an official NHTSA reliability rating or a probability that a car will fail.

Values and counts are as reported by ForCar; the source identifies 1999, 2000, and 2001 as its three higher-rate years, and 1997, 1995, and 1996 as its three lower-rate years after 1998. The table retains the source’s displayed values rather than treating them as a definitive sorted reliability ranking. ForCar’s rate is based on complaint submissions and production-run prefixes, not confirmed defects or all vehicles on the road. ForCar’s Grand Am complaint analysis reports an update in September 2026.
Which years deserve extra scrutiny?
1999, 2000, and 2001 in ForCar’s comparison
ForCar’s highest complaint rates are for 1999 (5.21), 2000 (3.13), and 2001 (2.93) complaints per production run. That makes these years reasonable prompts for more careful questions and inspection, not automatic reasons to reject every example.

2003 in CarComplaints’ ranking
CarComplaints reaches a different conclusion, ranking 2003 as the worst year by its own criteria and engine problems as the worst category. Its page shows 378 complaints for 2001 and 187 for 2003 in its displayed model-year comparison, and identifies 2001 as the highest raw total. It nevertheless rates 2003 worse using other possible factors, including repair cost or lower mileage. These totals are from a separate site and do not match ForCar’s extract and grouping; do not combine the two rankings into one score. CarComplaints’ Grand Am complaint pages describe its model-year comparison and reported problems.
What problems should you check before buying?
Cooling-system and intake-manifold leaks
CarComplaints highlights intake-manifold leakage reports for 2003, coolant leakage and cracked intake-manifold gasket reports for 2001, and intake-manifold gasket failure reports for 2000. These are owner-reported problem groups, not evidence that every car from those years has the issue. Have a mechanic look for signs of coolant loss or leakage and assess the engine and cooling system on the specific vehicle. The site’s repair-cost estimates and reported mileages are not a quote or diagnosis for the car you are considering.

Diagnostic trouble codes
An OBD-II reader can retrieve diagnostic codes that may help direct further troubleshooting. A code is a clue, not a root-cause diagnosis or proof that a car is roadworthy; have a qualified mechanic interpret findings in context. RepairPal provides Grand Am-specific diagnostic-code material, year-level problem pages, maintenance schedules, and recall lookup. RepairPal’s Pontiac Grand Am resource is a starting point for those materials.
How to compare two Grand Ams
- Review service records. Look for documented maintenance and repairs, and ask about any recurring coolant loss or engine work.
- Inspect condition and history. Assess rust, structural condition, and signs of crash damage or poor repairs rather than relying on the model-year label.
- Arrange an independent pre-purchase inspection. Ask the mechanic to evaluate the engine, cooling system, and any symptoms or diagnostic findings on that vehicle.
- Check recalls by VIN. Use the specific car’s VIN to confirm current recall status; a model-year complaint page cannot establish whether an individual vehicle has an open recall.
- Use complaint data as a tie-breaker. If cars are otherwise similar, the year-level figures can help shape follow-up questions, but the better-documented, better-maintained car with stronger inspection results is the more useful choice.
ForCar’s figures and CarComplaints’ rankings are both based on complaint data, which do not represent every vehicle failure and do not confirm that a reported defect occurred in every car. Their different methods explain why 1999 and 2003 can lead different “worst year” lists.
