POWER TRAIN,ENGINE07/03/2025
Vehicle equipped with 6.2l v8 engine. Have been experiencing hesitation upon acceleration, decrease in power/reduced performance, trouble starting, abnormal shifting (particularly from 2nd to 3rd and 3rd to 4th gear) for about two months. On two separate occassions(once about 1yr ago and the second time about a week ago) during normal use of the vehicle, the car started to shudder and the CEL began flashing. Both times I immediately pulled over and shut off the vehicle. Fluids were good, car has never overheated, regular maintenance has been performed as well. When I turned the car back on, the light was off and didn't show any signs that there was an issue. Two days ago during normal use of the car at about 35mph, a loud knocking/ticking sound started. I was about 1/8 mile from my destination so I attempted to make it there. Driveway is uphill and when I accelerated to get up the hill the sound got much louder and ticking was twice as fast. Shut off the car, let it cool, and knocking sound was just as bad the next time I started the car. Had the car towed to prevent damaging the vehicle further. This car is financed and i have three payments left on the 54 month contract. Today i reached out to the dealer about the issue and asked if I should bring my car to their service dept. I explained how i have been experiencing most of the issues that GM has identified as warning signs that indicate a potential engine failure and I was told theres no way my car has a recalled engine and the guy laughed at me when I tried to give him the information I found on the NHTSA website. Not really sure who I'm supposed to call to get some help with this issue.

The contact owns a 2013 GMC Yukon XL. The contact stated while driving at an undisclosed speed, there was an abnormal sound coming from the engine compartment. No warning light was illuminated; however, the "Service Engine" message was displayed on the instrument panel. The vehicle was taken to a dealer where it was diagnosed that the lifters needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer where it was diagnosed that the lifters needed to be replaced once again. The vehicle was repaired however, the failure persisted. The vehicle was taken to a dealer again to be diagnosed; however, the cause of the failure was not determined. The manufacturer was notified of the failure. The failure mileage was approximately 150,000.

I received a safety recall notice for my vehicle and scheduled an appointment for repair, #N212328790. Upon arriving, the dealer advised me there was a very small crack in the dash and if the dash cracked during the removal or installation, GM would NOT reimburse for any damage to the dash. The default was with the manufacturer and if they didn't replace it correctly, I'd be out serious money to replace and maintain the value of the vehicle.

The contact owns a 2013 GMC Yukon XL. The contact stated that the air bag warning light was illuminated. The contact received notification of NHTSA Campaign Number: 21V053000 (Air Bags) however, the part to do the recall repair was not yet available. The local dealer was contacted. The dealer informed the contact that should the dashboard get cracked, replacing the dashboard would be at his expense. The contact called another local dealer, Cannon Motors LLC (100 N Thacker Lp., Oxford, MS 38655), who informed the contact about the dashboard possibly being cracked and the associated fees. The vehicle was not diagnosed or repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 156,000. Parts distribution disconnect.

The issue is that we have to sign off on liability for the dealer to install the new safety airbag to state that we are accepting a cracked dashboard. This is ridiculous and the manufacturer (GMC) should have to replace the dashbboard along with the air bag.
STEERING,UNKNOWN OR OTHER07/14/2023
TRACTION CONTROL WARNING LIGHT INDICATE STABILITRAC NEEDS SERVICE AND IS NOT ON. OBD CODE READS BAD STEERING SENSOR. ACCORDING TO OTHER GM OWNERS ONLINE THIS IS A CONSTANT PROBLEM WITH THESE VEHICLES. MANY SHOW THE REPAIR INSTRUCTIONS ON LINE. THE WARNING LIGHT HAS BEEN OFF AND ON FOR SOME TIME WHEN CAR IS COOL ITS OFF WHEN IT SETS IN THE SUN IT GOES ON. I HAVE CONTACTED THE TOPEKA KS GM DEALER TWICE THIS WEEK TO GET THE COST TO REPLACE THIS SENSOR AND AM TOLD THEY WILL CALL ME BACK BUT NO ONE HAS.
STEERING,UNKNOWN OR OTHER06/04/2023
UNKNOWN. Truck would not move out of gear as the gear shift was just moving up and down and not catching any gears

Stopped at a light and went to pull off when the light turned green and the car would not move at the speed of gas I was giving it coasted into the Intersection. I had to turn the car off in the middle of an intersection, restart it and shift back into drive as I got down the road it did the same thing I’ll be in drive and go to apply gas and seems as though the transmission slips causing unsafe driving.

The truck locks start locking and unlocking on their own, the stabilitrac and traction control will cycle between on and off, the motor will shut off, it goes to limp mode, check engine light comes on, traction control light comes on, abs light comes on, it has stalled in drive throughs on the interstate, driving around town, the vehicle is at pat clemons gmc in boone iowa, they replaced the bcm and it is still happening, there is an nhsta campaign #14V61400 for a chassis control module recall, this vehicle vin is not in that, but it does exhibit all the symptoms mentioned in the recall, very much a safety issue as it can happen anytime, especially when it is raining or snowing, started about a year ago

I call this a "Panic breaking defect" I have experienced this on two different GMC vehicles manufactured 14 years apart. The first was a 1999 GMC suburban with mechanically operated throttle control. The second was my present GMC Yukon XL Denali with electronic throttle control. The defect: The close proximity of the accelerator pedal to the brake pedal makes it possible to have the right foot on both pedals at the same time. This results in high engine RPM and full breaking pressure, however, the anti-lock breaking system releases and re-applies the break pressure repeatedly allowing the vehicle to lunge forward a short distance on each cycle. To remove ones foot from the both pedals so as to apply it to just the break would result in the vehicle, engine being at high RPM, to allow the vehicle to speed forward resulting in a serious collision. True one could use the left foot, if able, on the break and then remove the right foot, allowing the engine to return to idle but on modern automatic transmission equipped cars where the left foot plays essentially no part in driving, such an action is not likely to occur. Also the ignition key could be turned off but with both hands employed to apply maximum pressure on the steering wheel to ensure maximum braking effort, that is not likely to occur either, besides that would result in lack of power steering and vacuum boost to the break system. A proposed solution: In a drive by wire environment it would be simple to send an idle signal to the throttle body every time the break pedal is pressed and this is the condition which occurs in a normal breaking situation. I have related this to the service manager of my local dealer and have also communicated it to General Motors Customer Support even offering to demonstrate the problem but have received no response. After all I am only a lowly customer and it matters not that I am also a retired Engineer!

Monday 5th 2022, (2pm)I was driving with the AC on high as I had just left the mall. The interior was hot. As I left the mall and came to a stop light...the car would rev at stop, and continue to do so until the light changed. I had the oil and transmission fluid changed at 135000. It is currently at 138000. I turned off the AC because it did not seem to work (to cool the car down) and rolled the windows down and open the sun roof. Tuesday 6th, I was leaving the store (4pm) and again I turned the AC on and approached a stop light. When I stopped at the light, the car started revving or idling in pulses again as it did on Monday, however as I went to turn right onto the street, there was no power steering at all. Startled, I pressed the brake, shifted into park, turned the SUV off. Then restarted the SUV and the steering had returned to normal. I kept the AC off and drove home.
AIR BAGS,STRUCTURE07/06/2022
Was told by my local dealer that they did not have to complete to recall unless I signed a document holding them blameless if they cracked my dashboard or cracked it worst than it already is. I declined to sign until I could investigate why I absolutely had to sign a document absolving GM of their bad design. I believe it to be unjust and insulting that we are required to choose between the safety of our vehicles vs the possible destruction of the interior due to GM's poor design. I did not get a picture of the document before I left the dealer but was told I could bring it back later if I wanted it fixed but I would have to sign the document.
