On passenger side, 4 of 5 wheel hub bolts (lug bolts) broke off during driving. The lug nuts did not come loose. The bolts actually broke off with lug nuts attached. This caused the wheel to separate from the car while driving. This caused an accident and $5,500 damage to the car. There were no warnings from the in-car information center.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story.
