Earlier this year, General Motors had a class-action lawsuit filed against it over claims that the brake vacuum pump used in certain GM full-size trucks and SUVs is defective. The original plaintiff in that suit, which was filed in the U.S. District Court for the Northern District of Illinois, claims affected vehicles may experience a sudden loss of vacuum pressure, which can cause the brake pedal to become hard and reduce overall braking power.
Now another lawsuit has been filed against GM in the U.S. District Court for the Northern District of Florida for the exact same reason. The plaintiff in this latest filing echoes the complaints made in the Illinois case, saying affected vehicles have a defective brake vacuum pump that may stop working, causing the brake pedal to become hard and reducing braking performance,
The plaintiff also says engine oil may enter the vacuum line connected to the brake booster, requiring both the vacuum pump and the brake booster itself to be replaced. The person claims they were left on the hook for a $500 repair to replace the brake booster, but have not made the repair as the replacement parts are just as defective as the originals.
According to Car Complaints, GM issued a Technical Service Bulletin (TSB) to dealer service departments addressing the problem back in 2015 – suggesting the company has known about the issue for some time.
“A customer may comment on a hard brake pedal or that increased effort is needed to depress the brake pedal,” the TSB said. “While performing normal diagnostics, fluid may be found in the brake booster and/or the booster vacuum line.”
The plaintiff in the case says the TSBs GM has released regarding the matter also contain “false, misleading, or deceptive information about the potential for curing the defects,” as the same problems will return once the dealership performs the suggested repairs.
This latest class action proceeding alleges the problem affects the exact same models as the initial suit. These include the following vehicles:
- 2015 to present Cadillac Escalade
- 2014 to present Chevrolet Silverado
- 2015 to present Chevrolet Suburban
- 2015 to present Chevrolet Tahoe
- 2014 to present GMC Sierra
- 2015 to present GMC Yukon/Yukon XL
