I drive a 2023 Chevrolet Silverado 1500 3.0L Diesel with the 10-speed transmission. The transmission control software failed to monitor/detect valve body wear or trigger a 5th-gear 'limp mode' safety net, resulting in three separate instances of sudden rear-wheel lockup at speed. The dealer was unable to replicate the issue during a service visit from 6/10 - XXX. The issue was raised as the transmission was shifting increasingly badly leading up to this service visit. The first full lockup occurred a few days after receipt of the vehicle on XXX driving eastbound on [XXX]. Off the gas, coasting downhill. Once everybody started speeding up, I increased the throttle gently and the truck shook violently. I initially thought I had been hit by another vehicle but realized it was the transmission. Speed was noted 24 mph. The second incident occurred XXX while traveling to [XXX]. Driving southbound between [XXX] and [XXX] at approximately 50 MPH in a coasting condition. Went to pass a slow vehicle and the vehicle jerked violently an locked the rear wheels. Initial assumption was that I had been hit. Was able to regain control and continue. The third incident occurredXXX while traveling from [XXX] to [XXX]. Driving eastbound on [XXX] at approximately 35 mph, when moving from a coast to acceleration posture, the vehicle again locked the rear wheels and jerked violently. Finally, onXXX when traveling southbound from [XXX] to [XXX], I stopped for fuel. When attempting to accelerate onto the freeway, the vehicle failed to engage 6 gear, stumbled, and then went into limp mode with a check engine light. On XXX a [XXX] dealer found code P0747 and addressed the issue with [XXX]. I was forced to rent a car to continue my journey to [XXX]. GM ultimately shipped my truck back to me one week later. The software 'fix' clearly did not work as intended and remains a serious safety hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This truck and hundreds, if not thousands of others has many issues with the electronic shifter. Not only do they frequently fail, but Chevrolet does not have any parts available to the dealerships for weeks. These Duramax 3.0 diesel engines are also a huge problem with the emission system and DEF. They constantly fail and we are spending thousands to repair. My truck is stuck at a dealership in [XXX]. I had to rent a vehicle to drive back home to [XXX]. The dealer has no idea how long it will take to get a shifter from Chevy. Is there any help available. Why aren't these shifters under a major recall? I am literally stranded after paying $65,000 for a truck! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine in my 2023 Silverado ZR2 (6.2L L87 V8) failed. It is available for inspection at Rick Hendrick Chevrolet ([XXX]). On XXX at about 67,000 miles, and the days leading up to it, the truck repeatedly struggled to start due to metal on metal contact, almost leaving me and my family stranded multiple times. Driving the vehicle produced a loud rattling noise at 2200 to 2700 rpm, and felt unsafe to drive. Especially with my family. The problem was reproduced and confirmed to be an engine failure by the Rick Hendrick Chevy dealership a week after being dropped off with an appointment. I have been told the engine needs to be replaced under the special coverage program (N252494003). The L87 recall inspection and oil change was completed on XXX also by Rick Hendrick Chevy. There were not warning lights or other symptoms leading up to this engine failure. The symptoms of struggling to start and the ticking noise as 2200 to 2700 RPM started that weekend before I brought to dealership. They got progressively worse. Dealership has said I will receive a new engine under warranty but no timeline for completion. Additionally I have not been furnished with a service loaner or option for one. Leaving me with no vehicle to replace it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine failed and was replaced at 38k. Transmission shudders, have been back to dealership multiple times for transmission shudder, have been told it was tires, torque converter, and valve body. When those items didn’t fix the issue, I was told it was the engine dfm and that it was normal and not a problem, AFTER they had already acknowledged the transmission issue by trying to fix it with a torque converter and valve body. Engine failed again at 54,604 miles while at high way speeds in rush hour like traffic in between [XXX] and [XXX], while pulling a camper. Truck oiled down the interstate and produced a blueish/milky looking cloud that caused drivers behind me to lock up their brakes because of bad vision, creating a hazard. I was told by gm that they wouldn’t tow the camper that I had to take care of that but they wouldn’t tow send a truck for my truck. Tow truck gets there and says my truck is too big and leaves. I called my own rollback to get my truck 3 1/2 hours later and they came and got it. Was stranded on the side of the interstate for 4 1/2 hours in 90 degree weather, to my knowledge the 2nd truck gm was supposed to send never showed up. Requested a buyback and was denied with no reason given. I have a lot of records if anyone wants them.

I had the 6.2 engine replaced at 38k miles. Now at 78k miles my new engine replacement is using 1.5qrt of oil within 4k miles. I am being told i have to watch the oil every 800 miles and report back to Chevrolet. I feel my investment is completely a loss of $60,000.00 + . I was told by the service tech that i will probaly have to have another engine replaced again.. My resale value is NO WHERE near worth anything and I am stuck.

Description of the Problem: My 2023 Chevrolet Silverado 1500 has a recurring transmission issue involving hard shifting and shuddering during normal driving. The transmission frequently hesitates, clunks, or jolts when changing gears, especially at low to moderate speeds. These symptoms occur consistently and have worsened over time. Safety Concerns: The harsh gear engagement and shuddering make the vehicle difficult to control smoothly. It feels like something will break while I'm driving. The unpredictable shifting behavior feels unsafe in traffic, during merging, and when accelerating from a stop, or driving on the freeway. I am concerned this may be related to widespread transmission complaints reported by other 2023 Silverado owners, including valve body and TCM failures. Service History: I have not contacted my dealership regarding the issue. Why I’m Reporting: I believe this transmission behavior presents a potential safety defect. I am submitting this complaint so the federal safety agency can review it as part of ongoing monitoring of similar issues reported for this model year.
