Trims
NHTSA's VIN data lists these trims for the 2008 Envoy. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Problems owners report
Owners have filed 77 complaints with NHTSA about the 2008 Envoy. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
| Investigation | Part | Opened | Status |

| Recall query RQ17002 Loss of Headlights · covers 7 makes | Exterior lighting | Apr 24, 2017 | Closed Mar 29, 2021 NHTSA's summary names recall 14V755000, 15V519000 NHTSA's record and documents |
