FUEL/PROPULSION SYSTEM, ENGINE, POWER TRAIN
On January 17, 2025, I was approaching the entrance ramp unto Interstate 10, traveling along at approximately 40 miles an hour, when all of a sudden I noticed that my vehicle started decelerating as I was pressing on the accelerator, trying to merge onto oncoming traffic. The engine started shuttering and vibrating violently! I noticed all the warning lights, gauges and indicators had come on simultaneously! There was a loud clicking sound coming from the engine compartment and backfiring coming from the exhaust. I evaluate the situation at hand and conduct a risk assessment of trying to continue on with this problem but decided to move over to the median. I was almost run into from the rear due to lack of power in which I felt would have been the result of my truck just losing power without any warning. I drove my truck to a Chevrolet dealership after speaking with a Service Advisor, on January 20, 2025. The Truck was diagnosed as needing to replace Cam Rod and Lifters.

At roughly 146,590~ miles the truck began making a knocking noise while driving at any speed, complainant had the truck towed to independent shop and was evaluated. Was told by shop that the engine can shaft pitted and engine metal shards had exploded and shattered throughout the engine. Making the opportunity for engine stalling or risk of fire/ smoking while operating the vehicle extremely likely. Complainant was told there was no access to engine replacements or parts at this time and the wait time to receive one was 4-6 months. No warning lights ever went off. Engine was eventually replaced entirely when the part became available by an independent service dealer.

ENGINE
In November 2023 my check engine light suddenly started flashing, my service parking brake light came on, traction control light came on and service ESC message was on the DIC. Then my truck started running really rough. At the time I was going roughly 10 mph. I took it to the dealership and they found a lifter had failed. My truck was at the dealership for a month. Fast forward to now, February 2025 and today I got the exact same lights appear on my cluster and same message. I was driving approximately 50 mph and my truck felt like there was a lack of power and there was hesitation in the engine.

The National Highway Traffic Safety Administration Campaign 1D Number for this recall is 24V797. We can not get any answers from GM as to when it can be fixed. We use this truck for heavy towing constantly. We do not want to be in harms way. Can you help resolve this problem?

1. Transmission recall N242454440 Chevy 2500hd Diesel Silverado 2020yr. Jan 2025 valve body inside transmission was replaced, recall pending, parts not available, NOT DONE. 2. Currently having this issue but no recall information found for my Vin...The "P22F9" engine code on a 2020 Chevy Silverado 2500 diesel indicates a recall related to the NOx sensor, specifically a "slow response" issue with the sensor, which the Engine Control Module (ECM) might not properly detect; this recall requires a software update to the ECM to address the problem. Key points about this recall: •Affected vehicles: Primarily 2020 Chevrolet Silverado 2500 and 3500 trucks with diesel engines, as well as similar GMC Sierra models. •Issue: The ECM may not accurately identify faults with the NOx sensor, potentially leading to emission issues and reduced engine performance. 3. P1089 fuel deceleration problem, several repairs were done but problem still persists. GM engineer's told dealership having problems with computer duplicated codes in memory. Engine light goes on and off over 50,000 miles, vehicle runs great and no gas found in oil. At one point engine light was off for 14,000 miles. *P1089 should definitely be a RECALL ITEM! MISC: Yes available for inspection. No safety problems as of yet. All repairs were done at dealerships and confirmed by dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO * I have contacted GM management staff in Michigan Mr. Craig Gidden, senior executive liaison, which referred me to CA customer service and supervisor, all to no avail, absolutely horrible customer service! They did not want to provide their contact information etc. *Contacted the GM arbitration department, they provided a case number but will not provide or respond to my emails for supervisor and GM legal department information.

SERVICE BRAKES
This morning it was 16 degrees F I drove about 6 city miles at about 35 mph. I was 1.5 miles from home when leaving a stop light the truck bogged down and was only going up to about 25 mph with the tach at 2000 rpm. It seemed at first that I was driving with the parking brake on but most V8's have enough power to override the parking brake. This acted as if I was pressing hard on the foot brake while driving and giving it a lot of gas. I probably would have had to floor it to go any faster. But was afraid of damaging something. Put on the flashers and drove about 15 mph with the tach at 1500-2000rpm. The dash displayed "Brake system failure 62 mph top speed", "Service ESC", "Parking brake failure" and "Service trailer brake system", The brake pedal was changing its height by itself. Pulled to side of road and pumped the brakes several times, shifted the transmission through park, neutral, reverse and drive and it seemed to operate normally. Pulled onto road and it was bogging down the same. Pulled to side of road again. Then started driving again with flashers on and the tranny shifted as normal, but the brake pedal went to the floor. Pumped the brake pedal and it still went to the floor. Drove slowly while checking the brake occasionally but still went to the floor during the 5 blocks to my driveway. The brake had no effect. My driveway slopes slightly upward so I stopped safely. All four wheel centers and brake rotors were too hot to touch after slowly driving the 1.5 miles this occurred over. About 15 minutes later I turned on the key and the dash displayed "Brake system failure 43 mph top speed", "Service ESC", and "Service trailer brake system". Fortunately there were no vehicles close in front of me when this started and many were behind me when driving with my flashers on due to quite a bit of traffic. This could have been a disaster had it occurred somewhere else. The local Chevrolet dealer that services it has not seen it yet.

Transmission shudders and has a delay in shifting/starting movement of the vehicle. This problem was noticed at 98k miles about a thousand miles after I purchased the truck from a dealership. It has been inspected, and repairs scheduled, but the transmission is still on back order after 5 months of waiting. No part ETA is available from Chevrolet corporate. This issue is a safety concern due to the fact that the vehicle could hesitate to accelerate in the event of needing to take evasive maneuvers to avoid an accident/road hazard.

FUEL/PROPULSION SYSTEM, ENGINE, POWER TRAIN
Vehicle purchased December 2020 Flashing check engine light that stays on- light did not stay on long enough for dealer to see, said they couldn't find any issues. The first time we had it towed and when they looked at it the light was no longer on. They were able to tell us what was going on with the vehicle when the light came on but said there were no problems. Flashing check engine light that turns off- "no light = no problem" dealer says. Eventually they printed pages showing engine misfires which we were initially told was no big deal. Later I was told I should get spark plugs changed, which I did. So far, flashing light has not reoccurred. Burns 3 or more quarts of oil between oil changes which I was assured by more than one rep that that was normal (on numerous occasions). Air conditioning quit working. Heater not working well and not at all on idle. The only setting I can really use to defrost and keep my feet warm is the "floor only" option. Mixed doesn't work, defrost only will freeze feet. Gas smell while vehicle at idle. Initially noticed when using auto start but have since noticed it does it with regular start as well. All issues have been brought to dealership, I will have to contact them for all the exact dates.

STEERING
We were driving on the highway when we attempted to make a turn the Steering wheel would not turn. We almost had an accident. I, [XXX], the Driver, had to swing out, and force the steering wheel to turn to get out of traffic. The service steering system with care light and the ESC Light came on. My truck is not that old and should not experiencing this type of problem. This was a very frightening experience that I don't want to go through this anymore. I call the dealership that I purchased the truck from and learned that other models had a recall on the same issue, but my 2020 had no recall on it. So therefore, they did not have to work it in to fix it. So, I'm reporting the issue so that no one else have to experience what I did.

ENGINE, ELECTRICAL SYSTEM, SERVICE BRAKES
Vehicle has been in and out of service for the past 5 months with multiple alerts including "Brake system failure 43mph top speed," "service esc," "service brake assist." On major interstate car would not accelerate past 43mph putting myself, infant, toddler, and wife in danger. Multiple attempts have been made to repair the vehicle and nothing has been successful. Lifters, CAM, torque converter, EBCM, master cylinder, calipers, and the list goes on. When this happens the brake is extremely hard to press making it difficult to stop the vehicle. Issue has been reproduced by dealer and attempts have been made under warranty to repair. Car only has 36k miles on it and the issue began prior to that. GM ongoing solution is to bleed the brakes, which clearly has not resolved the issue. Still hear ticking and noises from engine. Something needs to be done to remedy this issue. This is a safety hazard for myself, my family, and everyone driving around me.
