Comments

Do you drive a 1976 GMC F?

Just because a car has been recalled does not mean it is not a reliable car. Millions of cars get recalled every year. Recalls often involve problems that are rare but could cause a serious problem if they occur. So the risk to any given driver is often remote, even though there may be a few high-profile incidents traced to the problem.
