Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 2004 GMC Envoy. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
CERTAIN MAXZONE HEADLIGHT ASSEMBLIES, DEPO BRAND, P/NO 335-1120L-AS, SOLD FOR USE AS AFTERMARKET EQUIPMENT FOR THE ABOVE LISTED PASSENGER VEHICLES. DURING PRODUCTION THE LAMP HOUSING SHAPE DEFORMED DISTORTING THE ASSEMBLY ANGLE OF THE REFLECTOR AND INFLUENCED THE AIMING POSITION.

Complaints across nearby GMC Envoy model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.
