Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 30,000 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 provided federal record spans 1990–2011, omitting 1987 from the year-by-year timeline and preventing direct comparison to preceding or subsequent model years within this dataset. The earliest available data point from 1990 shows 61 complaints and 1 recall, representing a baseline that escalates dramatically through the generation—peaking at 487 complaints and 7 recalls by 2005—suggesting 1987 predates the documented surge in federal incident reporting. For 1987 specifically, Electrical System complaints dominate with 26 instances, while Vehicle Speed Control and Engine & Engine Cooling each account for 9; notably, fire complaints total 18 against only 2 crash complaints, though the data specifies no root causes for these incidents. This positions 1987 outside the high-volume complaint arc that defines 1992–2005, potentially indicating lower systemic defect rates relative to the generation's troubled middle years, though the elevated fire complaint count warrants specific due diligence during inspection. Given the absence of 1987 from the escalating recall and investigation trend visible from 1990 onward, this year likely offers greater mechanical simplicity and reduced exposure to the widespread issues documented in later models, making it a comparatively sound choice provided the specific fire history is verified.
