1997 GMC Envoy: what breaks, and at what mileage
What breaks on the 1997 GMC Envoy
Only 1 defect report has been filed with NHTSA about the 1997 GMC Envoy, which is too few to compute mileage percentiles or a risk score. The report reported other fuel system problem.
When each failure gets reported
Tick median reported mileage Solid middle half of reports Faint 10th to 90th percentile Colour how bad the failure is when it happens
How reports accumulate
Every report with an odometer reading, cumulative, from 0 to 200,000 miles. A curve that climbs early is a car with early problems, whatever its total.

Every reported failure mode
| Failure mode | System | Reports | With reading | 25th | Median | 75th | Per 1,000 | Typical repair | Severity |
|---|---|---|---|---|---|---|---|---|---|
| Other fuel system problem | fuel | 1 | 1 | — | 61k | — | 0.1 | $300–$2,200 | High |
This year had no usable recall paperwork, so the fleet-size estimate is the median of other years of the same model. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The odometer reading is the one the owner gave.
Other fuel system problem
Faulty gas gauge on a 1997 gmc envoy which first lead to inaccurate and random fuel level readings. Now it doesn't work at all, prompting the check engine light to be on constantly which means the check engine light is ignored since it is constantly on - this may mask other check engine situations from being noticed. *tr
Every year of the GMC Envoy
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 the reports on file say
The complaints recorded against the 1997 GMC Envoy are other fuel system problem (1 report, around 61k miles). With a sample this size these are anecdotes rather than a pattern, and they are shown because somebody looking at this exact car would rather see them than nothing.
Why this page is short
A model year needs about 8 reports before percentiles mean anything, and this one does not have them. Complaint volume tracks how many cars were sold and how long they have been on the road, so a thin page usually means a rare car, a new car, or a car whose owners do not file.
Other years of the same model do have enough: 1998, 2000, 2002, 2003, 2004, 2005, 2006 and 2007. The mechanical parts are often shared across those years, so their pages are the better guide to what this one is likely to do, with the caveat that a shared part is not a shared production line.
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.
