Dear Sir, I currently own a 2017 GMC Denali that had a potentially catastrophic failure with one of the alloy wheels that are on my vehicle. Mileage about 110,000 I recently went to have new tires installed on my vehicles when the tire shop manager came from the work area and said that he could not put a new tire on my one wheels. The reason the tire store could not put a tire on that wheel is because two of the spokes on the alloy wheel were broken. There were three spokes between the broken spokes. The are 12 spokes on the wheel and the two broken spokes were non adjoining. They were not next to each other. There were good spokes between the broken spokes. With a close inspection of the wheel there is no scuffing or impact damage to the wheel either on the outside of the wheel or the inside that would cause this failure. The spokes just cracked. The fact that the two broken spokes are not next to each other would seem to indicate that this was a manufacturing defect. I am writing to go on record of this failure of the alloy wheel on my truck. If someone would like to inspect the wheel, please contact me to arrange for a time to look at it. I have attached pictures of the wheel with the broken spokes. Regards, [XXX] You can see the cracked spokes at the 12:00 and 7:00 position on the wheel towards the center of the wheel.

I drive this vehicle on higher speed roads to work everyday. Roads also used by large tractor trailers and like larger vehicles. I was told by dealer that I had broken exhaust manifold studs at a previous oil change. While driving the truck it seemed to lose power for a short time but I was in traffic and assumed the loss of power at that time was related to a possible exhaust leak.I scheduled a appointment to have the repairs addressed. When I picked up the vehicle I was told that there was a ticking noise in the top of the motor. They stated it was the lifters and needed to be repaired for $7136 dollars. I researched the problem and found out how big of an issue this is specifically for the owners of the 6.2l (L86) engine. Highly concerned I schedule the repair and dropped the vehicle off. Shortly after the dealer called and stated the vehicle had bent push rod collapsed lifters damage to the cylinder head, camshaft and worn camshaft bearings now cost are $14350 or replace engine for $17000. I chose to replace top end. The next day I was called back and was told the bearing on the cam journals were down to brass and I would need new engine. Cost in just 24 hours not are $22000. This vehicle was maintained by this dealer also for all fluid changes. The belief is all the failures were related to the active fuel management system. (going from 8 to 4 cylinders ).

The rear window on my 2017 GMC Sierra shattered unexpectedly without any impact. The vehicle had been remote started in very cold weather and the rear window glass suddenly shattered while the truck was parked. There was no rock strike or external damage that would explain the failure. I later learned about GM Customer Satisfaction Program N192265660 regarding rear window defroster thermal events affecting certain 2014–2019 GMC Sierra and Chevrolet Silverado trucks. Based on the sudden failure and the conditions at the time, this appears consistent with that issue. The Auto Rear Defog feature in the vehicle settings was turned off, however the truck had been started using the remote start feature when the glass shattered. Photos of the shattered window are available. I am submitting this report because the rear window defroster system may cause the glass to overheat and shatter unexpectedly.

While the 2017 GMC Sierra was warming up via remote start, I noticed a smell of smoke as I walked by the passenger side of the truck. Then I heard a loud bang as I was walking around the rear of the truck. As I entered the truck from the driver's door I saw the back window, passenger side, shattered. The vehicle was then turned off. According to our dealership the vehicle was looked at under recall N192265660 and deemed safe in May of 2020. A call was placed to GM who said the recall expired in 2022. An offer was made by for payment assistance by the GM representative but could not say how much until we pay the dealership for a diagnostic. This is a know issue by GM. The location of the shattered window is situated inches behind where my child's head would have been had she been in the vehicle.The smell of smoke is extremely concerning because where there's smoke there's fire.

My L86 Engine had 250,000 plus miles and the engine went out. So we decided to rebuild the engine due to the truck being paid off and the cost of a new engine is much cheaper than a new truck. After the first rebuild the engine last around 10K miles. We pulled the engine back apart to find out that the crank bearings were shot along with the brand new GM crank that was purchased. After doing research, there was no enough clearance between the GM bearings and the GM crank. Basically the same issue that the L87 is having. After doing more research it determined by the part number on the crank and the part number GM provides on their website that the L86 and the L87 (engine with current recall) take the same crank. Therefore my L86 due to GM only making the L87 crank now and it replaces the original L86 crank we had to replace the engine a second time. I believe this relevant to all the L87 issues and any L86s that are being rebuilt. We ended up having to purchase aftermarket crank bearings to get the correct clearance on the second new GM Crank that was purchased. Truck is now running good now.

After 38,000 miles and 8 years of normal service (mix of city, highway, and 10% towing), my 8L90 transmission began to shudder occasionally. The problem first became apparent when driving slightly uphill, on cruise control at about 50 mph, or while slightly accelerating on a flat road, with no load in the box, and no trailer. It felt like I was driving across a rough patch of asphalt or rumble strips. Every half mile or so, it would shudder. Slowing down or speeding up stopped the rumble. The problem proved not to be caused by tires, U-joints, or AFM. The problem in fact was caused by defective GM transmission fluid, which was sold as "sealed for life", and rated for 200,000 miles, as factory-installed. That proved to be BS. If not repaired, this problem would lead to transmission lockup and/or lack of propulsion, which could contribute to a vehicle crash. The problem was solved by installing AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid, Product Code: ATLTP-CA. If GM properly cared for their customers, to make up for false advertising at the time of purchase, GM should publish and pay for GM Service Bulletin #20-NA-142, for all 8L90 owners, instructing owners to replace their transmission fluid every 5 years or 40,000 miles, whichever comes first.

My vehicle has lurched forward upon the first engine start of the day, under no throttle, on several occasions, throughout the life of my vehicle. Shortly after starting my 6.2 engine in my garage, if I shift my 8L90 transmission into Drive as soon as the engine RPMs settle to idle, the vehicle will lurch forward, screeching the tires. Luckily, I had my foot on the brake hard enough such that no one was injured. The harsh transmission shift into drive is dangerous, possible injuring passengers or my garage door. I've learned that if I wait 5 to 10 seconds, allowing the engine to idle (while the transmission oil becomes pressurized ??), then the shift into drive is normal, without any lurch.

I just don’t understand how this truck has 0 recalls.

I was test driving this 2017 Sierra 1500 SLT and experienced issues while braking. Issues with brakes as the vacuum level drops the brake assist decreases which meant I had to use excessive force to get the vehicle to stop. No warning light, nothing to tell me there is a low pressure brake. This could result in a fatality if a small animal or child walks/runs in front of the truck while truck is moving forward or backwards at low speeds. The dealer doesn’t acknowledge any recall on this vehicle because it isn’t noted as such with GM. I worry that all of the other recalls (4 others) may be an issue too, which include Frontal Airbags not deploying during an accident, faulty wheel sensor causes opposite wheel to engage and cause the vehicle to pull to one side, fuel leak, and child seat anchoring restraint instructions not included in the owners manual.

My 2017 GMC Sierra Brakes started acting up a slow speed it would seem like there were no Brakes or Pedal would push very hard. I pulled into a parking space at the store and it was like I had no Brakes had to push pedal very hard and Thank god there wasn’t a car in front of me because I would have hit it. The truck has new front and back Brakes and Rotors put. The truck was throwing some codes and 3 out of the 4 codes pointed to faulty Vacume pump. I pull a camper and sometimes a side x side so this is very concerning and I hoping to get this expense covered by Recall like all the other Models with the same issues.

Vehicle went into limp mode. 36 check engine codes popped up all related to cam shaft and lifter issues. Vehicle was taken to a shop and it has been determined that the passenger side lifters and rollers have sized due to the active fuel management system. This is the L86 GM 6.2 liter motor, that has developed the same issues that the L87 motor is being investigated for. There where no tail tail signs or check engine lights that were on prior the the lifter failure.

General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.

Risk: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.

Remedy: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.

General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

Risk: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.

Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 17287.

General Motors LLC (GM) is recalling certain 2017 Chevrolet Silverado 1500, and GMC Sierra 1500 trucks. The owner's manual for the affected vehicles may be missing instructions on how to use the tether anchorage and child restraint anchorage systems. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 225, "Child Restraint Anchorage Systems."

Risk: If the instructions are missing from the owner's manual, the child seat may be installed incorrectly and not be properly secured, increasing the risk of injury in a crash.

Remedy: GM will notify owners, and dealers will provide a corrected insert for the owners manual, free of charge. The recall began on September 25, 2017. Owners may contact GM customer service at 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 17307.

In the affected vehicles, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

Risk: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.

Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on October 13, 2016. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.

General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.

Risk: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.

Remedy: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.
