A class-action lawsuit has been filed against General Motors in U.S. District Court in Michigan over an issue related to the brake vacuum pump on certain 2013 to 2022 model year Chevy Malibu mid-size sedans.
According to Car Complaints, this lawsuit claims the factory cam-driven brake vacuum pump on affected Chevy Malibu models is defective and can cause a hard-feeling brake pedal and reduced braking performance.
The suit was filed by Virginia plaintiff Tiffany Johnson, who purchased a new 2017 Chevy Malibu in April of that year and later experienced a brake failure on the vehicle in September of 2021 when the vehicle had roughly 78,000 miles on the odometer. The repair shop replaced the vacuum pump at a cost of $118, however the pump failed once again in November 2021 when the vehicle had just under 84,000 miles on the odometer. These repairs were covered under the plaintiff’s insurance, although she still had to pay a $250 deductible.
A third brake vacuum pump and brake booster failure happened on the same vehicle in June of this year, the lawsuit alleges, which damaged unnamed “other components,” in the vehicle. The dealer replaced the vacuum pump, exhaust camshaft and gaskets in the vehicle this time, with the insurer again covering all repair expenses save for the $250 deductible.
As the Malibu uses a cam-driven vacuum pump, the suit claims that when the pump fails, “unintended mechanical resistance forms, affecting the timing of and/or damaging the camshaft and other engine components.” The suit also claims that GM is aware of the defective vacuum pump and the potential for it to cause damage to engine components, but has not done anything to address the matter. GM also allegedly refuses to extend the warranty on affected customer vehicles, Car Complaints reports.
This case will proceed in U.S. District Court for the Eastern District of Michigan. We’ll provide more information on the suit once an update is available.
