Power train 40,000 mi 3.7 yr in service

I BOUGHT A 2005 CHEVY AVALANCHE. 3 YEAR 36,000 MILE WARRANTY, AT 40,000 MILES THE TRANSMISSION DISINTEGRATED. $3,000 OUT OF POCKET........ I EXPECT A LITTLE MORE THAN 40,000 MILES OUT OF A $35,000 TRUCK. NOW I'M GETTING MAIL ABOUT A SPEEDOMETER LAWSUIT, I'VE ALWAYS BEEN A CHEVY GUY BUT IF THIS IS WHAT I CAN EXPECT FROM GM MAYBE ITS TIME FOR A CHANGE! *TR

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
