About this data
Problems, complaint counts, recalls and crash-test ratings come from the U.S. National Highway Traffic Safety Administration (NHTSA) public databases, last checked 2026-11-03. Complaints are reports from owners and have not all been verified by NHTSA.
How we score reliability: every model year starts at 100. Points come off for the number of owner complaints (on a log scale, up to 40 points), for each safety recall (2 points each, up to 15) and for complaints involving crashes, fires, injuries or deaths (up to 15). Popular vehicles get more complaints simply because more are on the road, so compare scores between similar vehicles. More about our method.
