Brakes were not 100% responsive starting in summer 2019; vacuum pump was replaced pursuant to recall in late 2019 and software error related to braking was addressed by dealer in january 2020. customer stated to dealer that brakes are still not 100% responsive, and that brakes will pulse a few times when pressed and before the vehicle actually starts to stop. dealer refused to consider that existing issues with last two recalls in 2019 related to brakes could be causing non-responsive brakes.
My wife was driving down a major road and a person pulled next to her at a stop to tell her that her brake lights were working only part of the time. gm had just serviced my vehicle and didn't catch it, and upon researching the issue, it is a known faulty design of the tail light assembly. the led brake light starts intermittently failing at the 2 year point, leading to drivers following drivers to not know that the leading vehicle is stopping. this is a common issue and the only response from gm is to make the customer buy a new $700 brake light assembly. the issue is so common that multiple companies have started brake light repair services and multiple youtube videos exist to walk individuals through the process of repairing their own brake lights. the cost of the repair is so steep that i hesitate to get the problem fixed, and though gm reportedly has developed a replacement light assembly that corrects the fault, they are not taking responsibility for the defective brake light assemble that these vehicles come off the assembly line with. the major danger is that we drive from the front of the vehicle and likely do not know our brake lights are intermittently failing--since gm cannot even catch this when they do service on vehicles (mine had been in the shop for an oil change a few weeks before the brake issue), then they are leaving a lot of customers driving without brake lights to avoid the cost of the repair even though they approved a faulty design.
Over the last several years, we have been hearing this clicking sound in our 2016 gmc yukon xl. additionally, we had experienced occasional times where the vehicles brakes would not function properly mostly in slower speed situations. in the last several weeks, the short range braking was hindered again as the break would 'stick' and not slow the car. several close instances of hitting either another car or family member. i then looked up on nhtsa if any recalls, and i noticed a recall which described exactly what we had been experiencing. we took the vehicle into the dealership yesterday and they told my wife it was fixed and sent her on her way to pick up my 5 children from school. a few hours later, the car just wouldn't break and my wife called me to actually go to the location on my child's practice so i could drive it home as she didn't trust the vehicle any longer. i took the vehicle back to the dealer the next day. upon their inspection, they said the vacuum pump was faulty and would cost $500 to fix. then i started to investigate further, and to my surprise, there appears to be a long standing issue with 2014-16 gm vehicles that have had faulty vacuum pumps. however, these haven't been recalled yet. the review also led me to the conclusion that the clicking sound we would hear appears to be related to this faulty part. unfortunately for me, my miles are beyond the warranty period but this has been a persistent issue for a long time. basically, it feels as if my family's safety was secondary while this known issue with the vacuum pump remained 'silent'. we bought this vehicle for the safety, dependability, and planned to use it up to 200,000+ miles. i am disappointed that a safety issue like the brakes would effectively be undisclosed to me as a car owner. i am hopeful gm will do all that is necessary to rectify our discomfort and lack of trust.
I had the recall (n192268490) applied to my yukon on 12 sep. i only experienced the problem described in the recall 2x prior to the recall. since the recall i have had multiple incidents much worse than than the original problem. tonight the brakes were so bad i over shot my parking spot and drove into some bushes. if a hard structure was there i would have damaged the car. this problem is repeatable. no warning lights come on but the "grade breaking on" light will come on. the break pedal was very soft and shuttered. i emphasize this is new since the recall was implemented.
Led brake lights failed and cannot be repaired. i cannot replace bulbs either. gmc wants $600+ to replace the light with one that has risk of failure, same as the original! no guarantee!
The right rear tail light brake lights have gone completely out. these are one solid housing and have to be replaced to simply fix the brake light. reverse and turn signal lights are ok. the housings cost 600-700 dollars each to replace which is a ludicrous amount to have to spend. in order to be within regulations for inspection, these have to be working. we feel there should be a recall as there are lots of complaints online about these housings.
The right rear brake light quit working. will come on when pushed against car. dealer said it was electrical in the brake light unit.
My 2016 gmc yukon xl recently began having a hard brake pedal when reversing out of parking spots, or when rolling downhill. a couple of times, when rolling forward downhill it malfunctioned causing me to run into a ditch. . the hard brake pedal had caused me to not be able to stop the vehicle several times. it would roll backwards (or forwards) until i shifted it in to gear or gave it gas. a few times i almost hit vehicles and pedestrians in my son's school carpool lane. there is no warning. no check engine light. just the horrible rock hard brake pedal which turns out to be a faulty vacuum pump per napa jimmy vasser chevrolet, that has now cost me $711.00 because it is not covered under warranty. my car has 54,000 miles on it. this is unacceptable.
Faulty break lights. the led circuit is faulty and cracks which requires the entire light assembly to be replaced.
The vehicle has experienced at slow speed or backing a solid/stuck brake pedal that wouldn't move. the pedal was basically stuck, not moving at all. this occurred coming to a stop at like an intersection or as stated backing out of a parking spot. it felt as if the truck wouldn't stop and no matter how hard the pedal was pushed it wouldn't move for a few seconds.
Brakes get very hard to push and do not work well when going slow speeds or backing up. unable to even fix as i have been told the part is on national back order! so i'm stuck trying not to crash with faulty vacuum brake part! left rear seat motor works, but small plastic part broke so seat worn move and is stuck in one position.
Low speed brake failure: at low speeds the brake pedal became firm and the vehicle did not stop in an appropriate time. this led to two near accidents. both times the vehicle was in a line of cars that was stop and go picking up children at after school. serious concern that the vehicle will not stop and injure children trying to load or unload. the problem appears to occur only at low speeds only.
Beginning around 70k miles, my wife complained of brakes not working at low speed in parking lots, especially in reverse, with very hard pedal, occasional occurring. while i was driving, occurred multiple times at gas station at very low speed during stop over on a long road trip at 80k miles. upon taking to gm dealership for another issue, gm service technician verified the concern. vacuum pump replaced on 12/14/18. few miles since but test driving has not had another occurrence. vehicle failure confirmation and repair done at joe bowman chevrolet in harrisonburg, va.
Driving at low speeds (5 mph or below) the brakes failed to engage. the brake pedal was stiff and offered little press. pressing the pedal extremely hard brought the vehicle to a stop. this happened multiple times in a single day, almost causing an accident in traffic and did cause me to bump into our garage wall. when a i took the vehicle in to be serviced, the vacuum pump had to be replaced. our vehicle as 39,800 miles. this appears to be a known defect: technical bulletin pit5361b exists a class action lawsuit has recently been filed (https://www.carcomplaints.com/news/2018/gm-brake-vacuum-pump-failures-lawsuit.shtml) a quick internet search reveals multiple similar issues. cost to repair is over $900 at gmc dealer.
Attempted to slow down by stepping on brakes but the pedal was extremely stiff and there was no stopping action. had to almost stand on the brake pedal with all my force to get the vehicle to stop before almost hitting the vehicle in front. we had the vehicle towed to a dealer and they said the brake booster pump had failed and needed replacement
On 9/25/18 while applying brakes the brake pedal became extremely hard to press and very hard to stop the vehicle. thank god it was in my driveway this occurred. my significant other came home from work on 9/27/18 and changed pads, lubed caliper sliders, and verified proper caliper operation. spent 9/26/18 talking with the dealer and checking recalls. all these repairs were suggested by the local dealer, by them of course. upon test drive after new pads were installed, the same issue happened. driving forward the brakes operate as they should or at least feel normal.
Brakes do not work at low speeds. gmc told me that the parts had been bought back by gm and there was no way to fix it 8 months ago and now they state there is a special warranty added except my mileage is over the warranty! brakes either are hard as a brick to push or/and don't work at all. i was told to rev the engine when going slow or backing up in order to make the brakes function properly. that was the advice for a mother of 4 children. ac is also blowing hot air.
When starting and stopping (depressing the brake pedal multiple times) such as at a left turn (waiting for traffic) or a drive-thru window, the brakes stop working and the car rolls forward even when the brake is depressed. if you press really hard it will usually stop- but it definitely rolls forward when you are trying to stop. the dealership says that a vacuum pump is faulty but this could result in an accident as i almost rolled into oncoming traffic while waiting in line to turn left at a "left turn yield on green light".
Tl* the contact owns a 2016 gmc yukon xl. on several occasions, when the brake pedal was depressed at low speeds, the brakes failed to slow down the vehicle. the contact stated that the failure was intermittent. the vehicle was taken to southern pines chevrolet buick gmc (10722 us-15, southern pines, nc 28387, (910) 692-2002) where it was diagnosed that the brake lines and vacuum pump needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 60,000.
