2008 Chevrolet Impala

If you’ve noticed that your Chevrolet Impala burns through its rear tires quickly, you’re not alone. “A class-action suit has been filed against General Motors Co., complaining that GM fixed rear-end problems on police versions of 2007-08 Impalas, but not those owned by some 400,000 other drivers,” reports The Detroit News. “The problem, according to the lawsuit filed in federal court in Detroit, causes owners to burn through rear tires.”

The Detroit News states that Donna Trusky of Blakely, Pa., saw the tires on her 2008 Impala wear out after just 6,000 miles, while other owners have complained about similar issues with excessive tire wear. “The wear has allegedly been attributed to faulty rods in the rear suspension linkage,” says Automobile Magazine. “Nearly 55 other owners have complained to the National Highway Traffic Safety Administration about the same issue.”

Autoblog reports that GM issued a technical service bulletin for 2008 Impalas sold to law enforcement agencies, but not to civilian vehicles sold in the 2007 and 2008 model years. “The lawsuit claims GM told dealers to replace both the spindle rods and the tires on affected cop cars and even authorized dealers to reimburse police departments that had already bought new tires,” writes USA Today. “But it says GM didn't offer the remedy to civilian owners.”
