The hazard
On certain vehicles, housing bolts for the variable camshaft timing system could break, allowing camshaft timing to deviate. If this occurs, the engine would revert to "limp home mode", limiting available engine power. This could increase the risk of a collision causing injury and/or damage to property. Correction: Dealers will replace affected bolts.
