While driving in stop and go traffic on a city street moving straight forward and inching the brakes to move with the traffic flow I noticed that the brake pedal got very hard and the vehicle was continuing to move forward even though I had all my weight pushing on the brake pedal lifting myself off my seat this happened 3 times before I was able to reach adequate parking. I have taken the vehicle to a certified gm service shop and after inspection they instructed me that I would need to replace the brake system vacuum pump, the brake booster, brake master cylinder and the tubing connecting the items. Resulting in a $1170. 00 repair and the service rep also stated that this would take care of the issue but cautioned the oil and filter changes needs to be maintained according to the manufacturers standards. I have owned this vehicle about fifteen days as of this writing I did by it from a dealer whom said he was unaware of this issue. Why is the NHTSA or whom ever continuing to let the dealers sell theses vehicles with a known safety problem without addressing the proper repairs stated in the TSB pit5361b that gm has sent out to there service centers. Serious accidents could and should be prevented with this issue.
The 8th of November 2018 while traveling through austin, TX - in heavy traffic; I nearly rear-ended another vehicle - the brakes got real hard, but the vehicle kept rolling. The brakes acted like the engine was shut off. I tried them again after resumed speed- and I tested them - on the third pump - they were rock-hard again. A vehicle shop in san antonio was able to consistently replicate the problem. It was a bad vacuum-pump-assist. It cost me $455. 00, it could have been worse, the mechanic told me that oil from the engine could have damaged the vacuum booster and/or the master cylinder. He told me chevy knows about it - #pit5361b - but I never knew about it - I almost rear-ended another vehicle. Vehicle had 48,500 miles when it occurred.
