1998 GMC Envoy: what breaks, and at what mileage
What breaks on the 1998 GMC Envoy
On the 1998 GMC Envoy, the failure owners report most often is wiper or washer failure, with 5 reports on file. Across every failure mode on this year, half the dated reports were filed before 80,000 miles. Overall it scores 59 out of 100, elevated risk for a 1998.
Elevated risk for a 1998 — 230th riskiest of the 271 1998 vehicles we can rate. 24 owner reports; fleet size estimated from this year's own recall paperwork.
What breaks on the 1998 GMC Envoy
Owners have reported 15 named failure modes on the 1998 GMC Envoy, and the three most-reported carry 42% of everything filed.
Wiper or washer failure leads with 5 reports and about 1.6 per 1,000 vehicles.
Other wheel or tire problem follows with 3 reports.
Other suspension problem follows with 2 reports, median 75,000 miles.
By system, the reports fall mostly into glass (5), lighting (4) and wheels (3).
At what mileage it happens
12 of the reports on the 1998 GMC Envoy came with an odometer reading, and half of those were filed before 80,000 miles.
Cumulatively, 17% by 50,000 miles and 92% by 100,000 miles of the dated reports had been filed.
The busiest stretch is between 90,000 and 100,000 miles, which alone holds 33% of the dated reports.
8% of the dated reports were filed below 36,000 miles, so this is mostly a story about older, higher-mileage cars.

What happens when these parts fail
Nothing in the reports on the 1998 GMC Envoy mentions a crash, a fire or an injury. That is the ordinary case and it is worth stating: most defect complaints are about a car that stopped working, not one that hurt somebody.
The average severity weight across every report on this year is 3.08, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: wiper or washer failure at $120–$800, other wheel or tire problem at $200–$1,500, other suspension problem at $350–$2,000 and other lighting problem at $120–$1,200. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
8% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 1998 GMC Envoy draws about 7.7 per 1,000 vehicles, which puts it in the 86th percentile of complaint rates among 1998 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.
The working figure is 3,116 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 1998 vehicles, which is what the risk score uses, is far more robust than the rate itself.
What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The odometer reading is the one the owner gave.
Wiper or washer failure
Wiper malfunction with exact symptoms that the newer gmc SUV are having. Mechanics are using the same part on all vehicles and it occurs spiratically. Dealers are saying this controlling device is common to have this occur. The wiper motor sometimes just stop or change speed on it's own and it has be occuring from 96 to current and they only want to replace certain ones. I own a 98 gmc envoy and this problem is happening. It doesn't happen all the time, but when it does it is dangerous to be driving in the vehicle especially traveling at higher speeds when it is raining.

Other suspension problem
Dt*: the contact stated while driving 45mph, the vehicle struck a dip in the road and the rear leaf spring assembly fractured which caused the vehicle body to drop to the ground. This incident occurred near the contact's home and the vehicle was not towed to a dealer. An independent repair shop mechanic inspected the vehicle and confirmed the fractured leaf spring assembly. The vehicle is waiting repair
Recalls on the 1998 model year
NHTSA has issued 2 recall campaigns covering the 1998 GMC Envoy, affecting an estimated 5,431 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover structure:body and exterior lighting. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
Recalls also distort complaint counts. Publicity about a campaign reminds owners that complaining is possible, so reports for a recalled component often spike after the recall rather than before it.
STRUCTURE:BODY
13,893 vehicles 2000-11-13- Defect
- Vehicle description: certain sport utility vehicles fail to comply with the requirements of fmvss no. 201, "occupant protection in interior impacts." these vehicles have a console cover/armrest cam latch that could release at less than the required load of the standard.
- Consequence
- During a crash, the console cover could open and the cover or items stored under it could injury an occupant.
- Remedy
- Dealers will replace the console latch mechanism.
EXTERIOR LIGHTING
3,116 vehicles 1998-09-28- Defect
- The daytime running lights were built with a candela value greater than 2,600, are located less than 100mm from the turn signals and hazard warning lamps, and are not deactivated when the turn signal or hazard warning lamps are activated. This does not comply with fmvss no. 108, "lamps, reflective devices, and associated equipment."
- Consequence
- This condition would make it difficult for drivers of oncoming vehicles to see the turn signal, increasing the risk of a vehicle crash.
- Remedy
- Dealers will install a new body control module and reprogram the vehicle with a new calibration that will turn the daytime running lights off when the turn signal or hazard warning flasher is activated.
Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.
How it ranks in the 1998 field
The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.
- Left fewer and less serious reports
- Right more, or worse

How 1998 compares with the other years
Elevated risk for a 1998 — 230th riskiest of the 271 1998 vehicles we can rate. Every score on this site is a rank inside its own model year, which is what makes a 2004 and a 2019 comparable at all.
Across the 10 model years of this car that carry enough reports to score, 2009 comes out best at 58 and 2000 worst at 76, with 1998 itself at 59.
No other year of this model scores meaningfully better than 1998, so if this generation is what you want, the year is not the lever.
Within the 1996–2000 generation specifically, 1998 is the strongest year at 59 and 2000 the weakest at 76.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 1996-2000 generation, 1998 GMC Envoy scores best at 59 and 2000 GMC Envoy worst at 76.
What this page cannot tell you
24 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 24 reports, 12 carried an odometer reading, so the mileages here describe 50% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
Questions this page answers
What are the most common problems with the 1998 GMC Envoy?
The most-reported failures are wiper or washer failure (5 reports, median 90,000 miles), other wheel or tire problem (3 reports) and other suspension problem (2 reports, median 75,000 miles). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.
Is the 1998 GMC Envoy reliable?
It scores 59 out of 100 on our risk index, which is elevated — 230th riskiest of the 271 1998 vehicles we can rate. The score is a comparison against other 1998 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.
Which year of the GMC Envoy is best?
Within the 1996–2000 generation, 1998 scores best at 59 out of 100 and 2000 worst at 76. Same body, same engines, different luck.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
