Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 1997 model year registers 383 complaints, marking the highest volume in the 1990-2002 period and exceeding the previous peak of 346 set in 1992. While the 6 recalls align with the 1995 and 1996 figures, Technical Service Bulletins climb to 142, continuing an upward trend from the prior year's 128. Dominating the feedback are 137 reports regarding Engine & Engine Cooling, with additional clusters in Fuel System and Service Brakes at 36 complaints each, alongside 9 reported fire complaints. This peak precedes a sharp decline in 1998, where complaints fall to 180, indicating that the 1997 model sits at the zenith of reported issues for this early production run. Consequently, buyers should approach this specific year with caution compared to subsequent models that demonstrate lower complaint frequencies.
