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.

Complaints across nearby GMC Sonoma 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.
VERIFIED EMPTY IMPORT SNAPSHOT
No exact NHTSA ODI investigation row was matched.

The canonical URL is this file’s permanent public identifier. Source IDs and timestamps show exactly what was matched and when; they do not turn the evidence into a verdict.
Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.
06 · Research paths
Diagnose first. Confirm fitment.
These are transparent searches, not diagnoses or endorsed parts. Recall remedies come before purchases; exact part fitment requires VIN, trim, powertrain, production date and OE number.

Check recalls and diagnostic information before replacing anything.
Awin US and R2 affiliate inventory are not published until a US programme, merchant and exact-fitment projection are approved. No offer currently has both merchant approval and exact vehicle fitment, so commercial links never count as evidence.
