TIRES, TIRES:TREAD/BELT
I purchased a set of Firestone Destination A/T2 tires from Firestone in Southaven, MS. I had the tires for less than 16 months. I took the tires in for inspection & was told the treat belts had separated from the tires. The tires are a hazard. the tires are 275/55R20. Driving on the interstate, I had to pull over as it felt as though the truck would overturn/rollover. They must be recalled. I contacted Firestone, they were of little to no assistance. Unable to obtain a refund or credit. I googled info on firestone tires & a plethora of information exhibited the same thing, problems with tread separation.

FUEL/PROPULSION SYSTEM
The CP4 pump failed while driving causing vehicle to stall. Upon failure, lost power to steering. Luckily we were on an access road for a rest area and not yet on the interstate. This resulted in a 14.5 thousand repair. No prior warning to pump failure. GM has recently settled a class action related to this pumps failure and has never recalled trucks with this pump to avoid failure.

ENGINE, FUEL/PROPULSION SYSTEM
I have not experienced a failure as of yet. But the CP4 fule pump is prone to fail. With that failure the engine is destroyed as well. So why is there no recall to get the CP4 fuel pump replaced? GM has been sued correct? A settlement of $35 million due to the failure of the CP4 fuel pump. So why is there no recall to address the issue before it happens? I have contacted GM directly and got no assistance. They just told me to fill a complaint. My Vehicle is a 2016 GMC Denali 2500 with the Duramax motor. This issue needs to have a recall! Why should owners of these vehicles with the CP4 fuel pumps have to wait until it fails and cost thousands of dollars to get assistance or reimbursement. Would appreciate any help with this matter. Thank You.

FUEL/PROPULSION SYSTEM, ENGINE
My 2016 GMC Sierra 2500 with a 6.6-liter Duramax diesel V8 engine suffered a complete engine shutdown—an issue that is both hazardous and expensive to repair. Fortunately, mine failed in a parking lot. No warning lights or symptoms were present. Failure is instantaneous and can occur any time rendering the vehicle inoperable on high-speed highways, Intersections, etc. Failure always leaves vehicle occupants stranded, creating an unsafe and dangerous situation. My vehicle was towed to a GMC dealer. Repair costs could be as high as $15,000. The 6.6-liter Duramax diesel V8 engine is equipped with a Bosch ‘CP4’ high-pressure fuel pump. These pumps are unreasonably fragile and prone to catastrophic failure causing instant contamination of the entire fuel system with metal shavings. General Motors has agreed to pay $35 million to settle with owners following a class action lawsuit that accused the company of installing defective Bosch CP4 high-pressure fuel pumps in certain Chevrolet and GMC pickup models. This action covered only owners in California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas.

ELECTRICAL SYSTEM, STEERING
While attempting to park my 2016 GMC Sierra 1500 at less than 5 mph, the steering wheel suddenly jerked on its own, the StabiliTrak warning light turned on, the dashboard flickered, and the entire electrical system briefly shut off. The anti-theft light also came on during this incident. After restarting the vehicle, it temporarily returned to normal, but this kind of malfunction is extremely dangerous — especially if it were to happen while driving. It’s very upsetting that GM has not included the 2016 model year in the recall for this exact issue, even though many owners are clearly experiencing the same symptoms as the 2014 and 2015 trucks that were recalled. This needs to be addressed for safety and fairness.

ENGINE, FUEL/PROPULSION SYSTEM
Motor stopped dead while driving on a local Interstate Hwy. Was able to negotiate the truck out of traffic without crashing. Not an easy thing to do in speeding rush hour traffic. Had the truck towed to a reputable repair shop and discovered the CP4 fuel pump had failed and shattered throughout the fuel system. Repairs in the amount of $13,520.30 incurred to get the truck back in service. The attached invoice includes $167.87 for other maintenance not related to the CP4 fuel pump repair. This is a known problem and safely hazard. A class action suit settlement is related to the CP4 fuel pump against multiple truck manufacturers. # [XXX] and can be found at [XXX] . Minnesota is not included in the class action and GM will not address my complaint. Why has this KNOWN safety issue not resulted in a recall?

ENGINE
Having the same issue as the recent recall on the 6.2L v8 engine failures. This has been an ongoing issue from well before the 2021 and up manufacturing dates according to many online complaints. My vehicle now needs a motor due to complete failure.This came out of nowhere with no warning very recently. It is not drivable and a new motor is not in my budget when I still owe money on the truck. GM needs to step up for the rest of these failures.
