How long do they last?

Complaint records show when problems get reported, not how long a car survives. Where owners gave an odometer reading, faults on the 2011 were reported at a median of 45,000 miles. Treat that as the point problems start being noticed, not a lifespan.

Common questions

Which Chevrolet Avalanche years should you avoid?

What is the best year for the Chevrolet Avalanche?

How many recalls does the Chevrolet Avalanche have?

How this was calculated

Every model year is scored over an identical window: complaints filed with NHTSA during the first 60 months after that model year went on sale. Without this, older cars look worse purely because they have had longer to accumulate reports.

Limitations. Complaints are unverified reports submitted voluntarily by owners; they are allegations, not findings, and reporting rates vary between models. Model years with fewer than 60 months on the road are marked provisional and excluded from verdicts. Cross-model comparison is withheld pending production-volume data.
