Three problems related to brake disc pads have been reported for the 2015 Chevrolet Suburban. The most recently reported issues are listed below.
In October 2017 we experienced brief periods where brake pedal became rigid and impossible to depress. The vehicle was taken to our local Chevrolet dealer. We described in detail the rigid brake pedal. The dealer wanted to do put new brake pads and turn the rotors. I thought it was strange that a vehicle with just over 40 thousand miles would need new brakes, but we had the work done. The dealer also wanted to replace the vacuum hose which powers the brake system. This work was also done. Next, on Friday March 23, 2018 we were traveling on an interstate at a high speed when the brake pedal became impossible to depress. We were very fortunate not to cause a serious accident. I had to have it towed to a dealer and rent a car. The following week we were contacted by the dealer doing the repairs. Our Suburban had a vacuum pump failure. This caused total brake failure. After some research I discovered that this vehicle's engine does not produce enough vacuum to power the brakes (unlike every other vehicle on the road). In any other car the only way you lose suction for your brakes is if the engine stops. In our Suburban the engine can be running fine and you may or may not have brakes. The warning system is totally useless as it isn't triggered until you experience total brake failure without any warning. While the vehicle was in the service department having vacuum pump replaced the dealer also explained that all four magnetic ride shocks/struts were locked in place and not functioning at all. This is another serious safety issue. I have never heard of shocks "locking up" . After some more research, I found this is a huge problem for gm vehicles. A problem that gm has failed to address. I have also had 3 major repairs on ac. Including ne ac lines and new compressor.
As we were driving from atlanta to miami, when we were getting off the highway the brakes on our 2015 Chevrolet Suburban failed to stop at 60 miles per hour, we almost reared-ended an eighteen-wheeler; with our family of five and our two dogs on board! all fluids had been checked on the car and the brake pads were recently changed. We just called and notified Chevrolet about this safety issue. We asked if there were any issues and/or recalls on our vehicle and the agent said that there were no issues or recalls regarding this type of vehicle. We made an appointment to have our car diagnosed as soon as possible. After researching online we found numerous posts on several sites from other Suburban owners reporting the same issue with their braking system not responding. What will it take for Chevrolet to acknowledge this brake failure system issue?!?! someone to get killed?!?! please look into this brake failure issue and address it promptly!!!.
I have a 2015 chevy. Suburban lt the brake pedal is hard to press and the car continue to roll even after I apply the brake despite the rotor and all the pads have been replaced. . . . . This is very dangerous.
