2018 CHEVROLET SUBURBAN Service Brakes Problems

No official incident has happened yet, but the brake assist kicks in, yet does not work until it's revving engine to over 4000rpm, which causes a sudden jerk and scary sounds from engine. I have had a few instances where the vehicle did not want to stop almost causing an accident, and these have happened without anything in the car other than my daughter who is 2 and myself. The most recent problem is a weird rattling sound while going uphill. Before this going uphill is extremely sluggish, where I have the gas peddle almost to the floor, but nothing happens other than decrease in speed until it finally, about 30 seconds-1 minute, where it kicks into overdrive. Even then, speed does not increase by more than 5-10 mph depending on the incline. I have not brought it to get looked at yet, as I've seen these issues have been reported by numerous consumers without any recalls being sent out other than the breaking system update.

The Trailor brake system, engine light, stabilitrak control system and antilock brake system is on due to the wiring of this vehicle.

Vehicle starts dinging with warning - Service Trailer Brake System - and warning - Action Required Steering Assist is Reduced Drive with Care - ABS Light - Traction Control. Power steering goes out and assumedly ABS and Traction Control stop working.

My rear left tire locks when I’m doing sharp turns and I don’t see any traction control lights come on when that happens

My car was acting weird, brake pedal was extremely tough to decompress, speed then was affected, and ultimately the brakes failed.

When placing the car in reverse, the car started to go backwards quickly and I had to put all my weight on the brakes and it took about 40 feet for the car to stop.

The vehicle began to shake as if it would shut down. Then, the engine light came on. Then I received three text message alerts. We were shown paperwork regarding the service history that was done at Philips Chevrolet. Now we’re getting alerts regarding work that has to be completed within 7 days.

My wife and son were traveling on the interstate in Indianapolis and the brakes began to fail in our 2018 Chevy Suburban. The brake pedal was almost impossible to depress to get the vehicle to even slow down. She was afraid that she was not going to be able to stop and get in a crash. Fortunately, she was able to maneuver the vehicle to the shoulder as it finally slowed down enough. She was afraid to go any farther to an exit for fear of not being able to stop down a sloping exit. So she was able to come to a stop on the shoulder of the interstate. Their was a warning light that came on as this was happening, which was the ABS warning light. It was towed to Andy Mohr Speedway Chevrolet and they have diagnosed it as a failed vacuum pump. After doing research, I found that there is a recall on 2018 Chevrolet Suburban for the vacuum pump. However, the VIN on my vehicle wasn't included. The recall number is N192268490. The information listed in this recall sounds exactly was happened to our vehicle causing the very dangerous condition that could have resulted in a tragic crash.

I DRIVE A 2018 CHEVY SUBURBAN. THIS CAR HAD NO LIGHTS ON AND HAS LESS THAN 18K MILES ON IT. IT IS JUST OVER TWO YEARS OLD AND THERE ARE NO RECALLS ON THE VEHICLE. I WAS DRIVING WITH MY [XXX] CHILD AND WE HAD DRIVEN ABOUT A MILE. WE WERE ON THE FEEDER ROAD ABOUT TO GET ON THE FREEWAY. THE CAR STARTED SPONTANEOUSLY ACCELERATING ON ITS OWN. JERKING FASTER AND FASTER WITHOUT ME TOUCHING THE GAS. IT WAS LIKE WE WERE ON A RUNAWAY TRAIN. I PANICKED AND SLAMMED MY FOOT ON THE BREAKS. THERE WERE NO BREAKS - NO TENSION OR PRESSURE IN THE BRAKE PEDAL. THE PEDAL JUST CONTINUOUSLY SLAMMED INTO THE BOTTOM OF THE CAR. I COULDN'T STOP US. I THOUGHT QUICKLY AND SLAMMED MY FOOT ON THE PARKING BRAKE AS OUR CAR CONTINUED TO ACCELERATE QUICKLY WITH NO BRAKE FUNCTION. WE JOLTED TO A STOP AS CARS ZOOMED AROUND US HONKING AND YELLING. WHEN I TOOK THE CAR OFF OF THE PARKING BREAK, THE SAME PROBLEM CONTINUED. NO BREAKS AND SPORADIC ACCELERATION. IMMEDIATELY AFTER THIS INCIDENT A LIGHT CAME ON THAT SAID 'SERVICE STABILITRAK'. THE CAR WAS TOWED TO THE DEALERSHIP. I'M SHARING THIS FOR ALL CAR OWNERS TO REMEMBER THE POWER OF YOUR PARKING BREAK IN AN EMERGENCY. IT'S ONE THING TO BE ANNOYED WHEN YOUR CAR WON'T GO, BUT IT IS PURE PANIC AND FEAR WHEN YOUR CAR WON'T STOP AND KEEPS GOING FASTER - ESPECIALLY WITH YOUR PRECIOUS CHILD IN THE BACK SEAT. *JS PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
