How to read this before buying
Complaint volume is not the same as failure rate. A model that sold in large numbers, or one that has been on sale for many years, accumulates more complaints without necessarily being less reliable. Use these figures to learn which systems to inspect, not to rank one model against another.
The single most useful next step is to check the specific vehicle's recalls by VIN — a recall repair is free at any franchised dealer, but only if it has actually been done.
