| Description of the problem | In september of 2019, gmc issued a recall for several gmc vehicles regarding "service brakes, hydraulic:power assist:vacuum". As such, the vehicle was serviced at the dealership per the instructions issued by gmc. However, several months later, while operating the vehicle in reverse out of a crowed parking lot, the brakes failed to stop the vehicle. Placing the gear in neutral along plus the emergency brake, was required to stop the vehicle. The was an extremely close call to the safety of the surrounding bystanders in the parking lot. Upon discussions with both the dealership and gmc, it was reported that the current recall only reprograms the components (reference the letter issued by gmc and the nhtsa's web site for this recall). It was further commented by both the service manager at the dealership and customer service at gmc, that this will not address all vehicles identified in this recall, meaning more action may be required to fix the underlining issue. In this case, several components were needed to be physical replaced, namely the vacuum pump. In addition, it was acknowledged by both the dealership and gmc that a certain percentage of these vehicles identified in the original recall will experience similar issues (brakes failing to stop the vehicle). During the call to gmc customer assistance (866. 790. 5600), the senior manager refused to take the advice to inform all customers/consumers of this dangerous ongoing risk. Even though it's a known failure, gmc has yet to provide additional notification to consumers that the current recall may fail to address the underlining safety failure to the braking system. Gmc should issue a new recall to advice the replacement of the physical components of the vacuum brake assistance system by all effected vehicles immediately. Otherwise, they will not replace the parts unless the consumer experiences an actual failure. |
