2007-2008 Chevrolet Impala Owners Suing GM Over Tire Wear
Is there a reason why some owners are seeing excessive rear tire wear on their 2007-2008 Chevrolet Impalas? A new lawsuit says yes, pointing directly to faulty rear suspension bars, and is seeking reparation from General Motors as a result.
The lawsuit was filed under one ower, Donna Trusky, according to The Detroit News, and stated that she had to replace her rear tires due to wear twice in under 25,000 miles. The wear has allegedly been attributed to faulty rods in the rear suspension linkage. Nearly 55 other owners have complained to the National Highway Traffic Safety Administration about the same issue. For the record, Chevrolet built close to 423,000 Impalas over the course of the 2007 and 2008 model years.
The issue isn't exactly a foreign one to GM. In fact, the company recalled police-spec Impalas in 2008 to address this very problem, but has yet to issue something similar for civilian vehicles. The automaker tells the News that the police-spec and civilian Impalas are different enough (i.e. different suspension parts) that regular cars didn't need the fix. The recall involved dealers realigning the rear wheels, replacing the rods, and replacing worn tires if necessary.
According to one of the owners who filed a complaint, there is a "fix kit" available to customers, but is required to be purchased by the owner, and is not covered under warranty. When we contacted GM, they let us know that a technical service bulletin was issued to dealers on procedures to fix the issue, there was no kit made available by the manufacturer.
