DETROIT - A lawsuit claims General Motors Co. treated the police better than average citizens when taking care of a defective part in 2007 and 2008 Chevrolet Impalas.
The lawsuit alleges that Impalas from the two model years have defective spindle rods, which connect the suspension to the rear wheels. The defect causes the wheels to misalign, which makes the tires wear out faster.
GM fixed the part on police versions of the Impala three years ago but didn’t correct the same problem in hundreds of thousands of other Impalas, according to the lawsuit filed last week in Detroit.
According to the lawsuit, GM sent a bulletin to dealers in June 2008 telling them to replace the spindle rods and tires on affected police vehicles. But GM allegedly didn’t offer the same remedy to non-police owners.
A GM spokesman confirmed that GM issued a service bulletin for police cars from the 2007 and 2008 model years because of rear suspension problems. But he said the company wouldn’t comment further.
