ENGINE
On December 29, 2022 I stopped at the bank for 2 minute and when I got back to my truck I noticed smoke coming out from under the hood. I immediately called 911 and luckily some nice people were able to get my hood up safely and the bank provided a fire extinguisher before the fire trucks arrived. It was engulfed in flames. The fireman said it appeared the fire started in the wiring at the engine. I had a recall fixed a while back for the engine block heater so I was worried maybe they didn’t repair the recall. A week after the fire I received a 2nd recall in the mail for the same recall. Today is July 9th and my truck is still in the shop waiting on parts that have been on back order this whole time. GMC told my insurance company they were sending someone down to look at it. Never heard anything back. This could have been so bad had I been driving it when the fire started. So here I am going on 7 months without my truck all while paying $942/month. I just want something to be done to speed up the repairs that my insurance has paid. Estimate is $22,000

STEERING, SERVICE BRAKES, ELECTRICAL SYSTEM
1st incident - tried to park turned in and steering went wild stability control light came on & others then truck shut down. 2nd Incident 2 days later- tried to turn off street (with grandkids in car) same thing steering about snapped my wrists off- check engine light came on and others then truck off this was all in a matter of seconds. I turned it on the info system on dash told me to roll down and then roll up window. Husband when driving noticed barking issues - really having to pump brakes (week before) We looked up recalls they are there for both issues for my year make but I have a bigger engine that the recall states so I am not covered yet it is doing all that same stuff for the recall which my husband put it what the truck was doing and found recalls just not for our engine size- THIS TRUCK IS NOT SAFE TO DRIVE AS WHEN YOU TURN IT WILL SHUT OFF IMMEDIATELY.

ENGINE
Truck started to jerk if driven over 20 mph. Before this the dashboard (electric) notification showed truck heating up but the temperature gage was not reading any overheating. Prior to this the whole electrical system in the truck started to mess up. The radio changed channels without actually changing the radio channels. Unable to connect the Bluetooth because it calls my phone contacts at random. Had to get a new transmission that cost 5,000 and this was recent. The truck is still jerking but is drivable over 20 mph.

SERVICE BRAKES
Brakes intermittently quit working at slow speeds. Sometimes while pushing on the brake pedal, the brakes don't respond, I have to increase the force placed on brake pedal. There is also a pulsating sensation at the pedal like the ABS is being applied, even though I am traveling at slow speeds, and it takes much longer to stop the vehicle. There are no warning lights that come on and there is nothing on the message center stating there is an issue. Has happened multiple time, usually in a parking lot, or in stop and go traffic. Also has happened when vehicle is in Reverse. Have never had the issue at highway speeds.

SERVICE BRAKES
2017 GMC Sierra K1500 with 59,xxx miles. Recently noted braking issues with vehicle in parking lots or at slower speeds. The brakes are difficult to engage. I do not notice this issue when driving at higher speeds. On 3/27/23, I backed the vehicle out of my driveway and had a near miss collision as it was very difficult to engage the brakes and stop the vehicle. After the near miss, the brakes, calipers, and rotors were inspected and all were in good working condition. I contacted the dealership where the vehicle was purchased. The representative from the dealership informed me that this braking issue was addressed as a previous recall for N192268490 ZPSR (Product Safety Recall) on 5/24/21. On 5/24/21, I took the truck into the dealership for another issue and this recall was addressed at the same time. I was not having any issues with the brakes at that time. The representative informed me that the recall was closed on the truck, and they now charge $200/hr if I want to bring the vehicle in for service. The current braking issues appear directly related to the reported braking recall issue that was reportedly repaired on 5/24/21. The vehicle is not safe to drive and would appreciate assistance from the NHTSA to safely resolve the issue.

POWER TRAIN
I have persistent transmission problems documented on multiple dealer visits where I purchased the vehicle. The first one was after 6000 miles. A large clunk sound and vibration occurred after shifting gears in the 30 mph range. The dealer told me this was a know issue related to the transmission manufacturer lubricant conflicting with the GMC transmission fluid. They did a flush and replace and for a time period it settled down. I have 56,000 miles now and the latest complaint I made was when nearing a stop at 5-10 mph the transmission did a massive clink. I had two others in the vehicle that observed this over 20 times. I immediately scheduled a service to look at this. After 4 hours they told me nothing is wrong. Since then the transmission has a light clunk shifting at low speed so I wonder if they lied and flushed the fluid. They said no metal was in the fluid. Online websites show many posts of owners hanging this issue. I was never shown a bulletin on any reported issues and would like to see every one related to the 8 speed transmission. My standard powertain warranty has expired after 5 years. I fear the value of this vehicle is impacted by so many complaint, no action by NTSB, and questionable practices by two GM dealers that serviced my vehicle. I would like to see a recall as this isn’t just my issue. I would like to see what investigation NTSB has done on this topic. I have printed service re odds for each I have complained about the transmission and now believe the dealer was aware of the issue and GM bulletins coached them how to tell me there is no issue. The last statement made was also odd, the service advisor told me that the clink is because the transmission sometimes goes from 3rd to 1st and skips second gear. I was charged to have them look for a problem and if this a known issue to both GM and the NTSB shame on you both.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
There has been a recall on the assisted braking pump. My truck is not on that recall as of now. But I am having the same braking trouble at slow speeds. Is there any way the company will fix this issue.

ELECTRICAL SYSTEM, VISIBILITY/WIPER
Started my truck to go to the store. When me and my son got in we could smell like hot plastic burning. Figured someone was burning trash so we proceeded to the store. About a mile down the road it sounded like someone fired a gun inside the cab of the truck. So being a combat veteran it triggered me! I instantly swung for the back seat thinking someone was back there and noticed the rear sliding window on the drivers side had blown and shattered. I found a recall online that gm had put out about this specific issue happening. So when I called Varney Gmc of Bangor Maine. They told me the recall had Ben done at 97000 miles and there was nothing they could do unless I paid for it…

ENGINE
Misfire with code PO300, Ticketing from engine at higher RPM/lose power and seems to be misfiring. Check engine light would blink and then shut off. Four rockers found to be bent push rod. - Replaced right and left side lifters and guides. Replaced Vlom and 1 push rod. Dealer diagnose and repair. Lifter failure due to engine switching from V8 to V4. Very expensive and very common problem with this type of engine. Truck is young with only 74,000 miles on it. Had to replace the transmission at 70,000 also.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
Fully enclosed LED tail light (turn and brake integrated into 1 LED "strip") with no visible moisture ingress/egress system showing retained moisture and no longer functional. Dash light for "rear signal brake light failure" appears. This rear light unit is NOT serviceable or repairable when a light goes out and is fully sealed aside from the reverse light (incandescent bulb and functions fine). LED's should have a lifespan that outlives the vehicle and a major incentive to have LED integration with lighting is the lifespan and reduced need for service. Now the taillight and brake light stop working and can not be fixed without spending <$500 per side. This is a safety issue that seems to be closely related to the issues with the GMC Yukon's of the same generation.

SERVICE BRAKES
The trailer brake system is displaying a warning. The truck has less than 50,000 miles and the tow option has never been used. I am told that it would be risky to use it without repair. this is a safety issue that should be a recall. I have checked and there are thousands with the same issue and it has gone on for years without being addressed by GM or NHTSA. It's time to step up and take care of this situation. There is no telling how many have been injured or killed by this. if nothing is done I will approach someone in the media.

SERVICE BRAKES
While parking I was backing up to straighten the truck in the space. When I went to stop I noticed that "normal" pedal pressure was not stopping the truck and I could tell vacuum was not available to boost the brakes, causing me to have to "stand on the pedal", almost causing me to hit the car behind me. I purchased the truck used four months ago and when checking recalls the nhtsa says none are open so I assume it has been addressed but didn't fix the issue obviously.

UNKNOWN OR OTHER
The radio in my truck acts on its own (buttons push by themselves). The problem is known and I’m fine with turning my radio off instead of paying a lot of money for a new one. I’ve been fine with it until recently. First problem I’ve let go for a while now which is that it turns on by itself while driving which is a distraction. But biggest problem now is not only did the radio turn on by itself but it also went into the backseat reminder and turned it off. I do have an infant and I hope to never forget. But when paying for a vehicle this is a feature you pay for. No one should lose a child bc of this. I’ve talk to a dealership about the initial problem and have done research on it. There is no warning signs. Vehicle has not been inspected by any others. I do have a video of the backseat reminder turning off without my control.
