2011 Chevrolet Suburban 2500

This year drew an ordinary 155 complaints for a Chevrolet Suburban 2500 — the model's median is 118. What they were about is the unusual part: 9% of them mention become, against 3.4% across the model's other years.

NHTSA opened a defect investigation into this model year.

What the complaints were about

• become — 9% of this year's complaints, against 3.4% across the model's other years (2.7×). Owners wrote it as: become, 000 vin.

Words owners used for the same problem are counted together, so a fault written four different ways is measured once. Grouped by which complaints they appear in, not by a list anyone wrote in advance.

What owners wrote

THE DASHBOARD IS CRACKING AND CAN BE POTENTIALLY DANGEROUS IF THE AIRBAG DEPLOYS. IF THE AIRBAG DEPLOYS THE CRACKED DASH COULD BECOME MULTIPLE PROJECTILE MISSLES.

THE DASH IS CRACKED AROUND THE CORNER OF THE PASSENGER AIRBAG. IN THE EVENT OF AN AIRBAG DEPLOYMENT, THE CRACKED DASH COULD BECOME A PROJECTILE AND CAUSE HARM TO OCCUPANTS.

How this was worked out

Every year of the Chevrolet Suburban 2500 was compared against its own history rather than against other cars, which removes popularity and age from the answer — a common car draws more complaints at equal reliability, and an older one has had longer to accumulate them. A year is flagged when it drew at least 2.5× this model's median and at least 50 complaints.

This is a fault record, not a review. Nobody files a federal complaint to say the car was fine, so it shows what tends to go wrong — not whether owners liked it, and not whether it is a good car.
