Manufacturer file
What the Chevrolet records can tell us
The Chevrolet file currently stops at 9 nameplates: Blazer, Colorado, Equinox, Silverado 1500, Suburban, Tahoe, Traverse, Malibu, Trax. Those 95 model-year entries contain 22,997 owner complaints. The missing denominator matters because these records do not say how many vehicles were on the road.
Engine appears most often in the component tags, with 5,751 mentions. A single complaint may carry several tags. I use the total as a prompt to read that system's contract terms, not as odds that a repair will happen.
Across the same model years, NHTSA records show 346 recall campaigns and 92,288 manufacturer communications. Recall repairs are handled separately from a paid service contract, while communications include far more than defects.
