What stands out
Owners have filed 79 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Powertrain accounts for 29% of all owner complaints filed against this vehicle, across 8 categories tracked.
The failure pattern owners describe
The 2024 Silverado powertrain is plagued by systematic failures that owners describe as dangerous and unacceptable for a new truck. The transmission valve body is the most common culprit, failing suddenly between 5,000 and 15,000 miles without warning. Owners lose reverse capability, get stuck in limp mode capped at 25–35 mph, or suffer complete power loss at highway speed. Dealerships confirm the defect immediately, but the replacement part is on national backorder with no ETA—waits stretch to 3–6 months or longer. GM has not issued a formal recall despite acknowledging the issue internally; one owner's vehicle was included in recall 25V274 but she was never notified.
Owners also report transmission shudder at low RPM (1,100–1,300) and highway speeds that feels like a "rumblestrip," with vibration worse in 4WD. Dealers diagnose torque converter clutch slip but offer no permanent fix. Cold-start hard shifts, where the transmission jerks harshly into gear seconds after startup, plague newer units, worsening in cold weather despite dealers claiming it is "normal."
Engine failures with internal bearing damage occur at shockingly low mileage, leaving owners stranded and forced to wait for engine replacement while engines are backordered. One owner reports the 6.2L is experiencing failures not covered under active recalls that apply to earlier model years.
Throughout, owners cite lack of transparency from GM, unavailable replacement parts, no loaner vehicles, denied rental reimbursement promises, and salespeople claiming these issues are "normal" or will resolve with time. The consistency of these complaints across dozens of unrelated owners points to systemic manufacturing defects, not isolated incidents.

Failure modes owners describe
Transmission Valve Body Failure
Defective valve body in the 10-speed transmission causes sudden loss of drive, inability to shift into reverse, limp mode activation, and loss of power at highway speeds. Multiple owners report the part is on national backorder for months with no ETA, and GM does not appear to have a permanent fix yet.
When: Generally between 4,900 and 15,000 miles; some failures occur earlier without warning
Symptoms owners cite: Sudden inability to shift into reverse (most common); Loss of all motive power while driving; Vehicle stuck in limp mode with reduced acceleration to 25–35 mph; Hard, jerky downshifts or transmission shuddering; Check engine light with codes P2732 and P0700; Message displayed: 'Reduced Acceleration - Drive with Care' or 'shift to neutral and restart'; No warning signs prior to failure in most cases
Codes mentioned: P2732, P0700
Repairs/costs cited: Transmission valve body replacement required; part on national backorder with 3–6+ month wait times. Some owners report dealers cannot locate replacement parts at all. Dealers have suggested rebuilding transmission instead of replacing, which owners reject for new vehicles.
Recalls/TSBs owners mention: Recall 25V274 exists but was not communicated to owners; vehicle not flagged in GM app during routine visits. Service bulletins issued but no formal recall in place for many vehicles. GM has advised that software monitoring is being attempted but no permanent solution has been implemented.
Transmission Shudder / Vibration (Torque Converter or TCC Slip)
Engine shudder or transmission vibration at specific RPM ranges (typically 1,100–1,300 RPM) and low speeds (30–45 mph), often described as a 'rumblestrip' feeling. Worse in 4WD and on inclines. Multiple TSBs exist for prior model years but issue persists on 2024 models.
When: Starting as early as 4,500 miles; progresses over time
Symptoms owners cite: Shudder or vibration at 30–45 mph, around 1,100–1,300 RPM; Continuous vibration when holding steady speed or slightly accelerating; Rumblestrip or rough sensation during light acceleration; Vibration felt through steering wheel and fuel pedal; No warning lights in most cases; Not present in low gear (L9) or tow mode; Worse in 4WD and on inclines; less noticeable when decelerating or accelerating hard
Codes mentioned: TCC Slip (Torque Converter Clutch slip, diagnostic data)
Repairs/costs cited: Dealers report TCC slip on diagnostics but no clear repair path. Some suggest transmission fluid flush or control module reset. Active fuel management system blamed by some dealers but owners dispute this explanation. Repair attempts have been unsuccessful or incomplete.
Recalls/TSBs owners mention: TSBs identified for 2500/3500 models and prior Silverado 1500 model years but unclear if 2024 models are covered. No formal recall. GM diagnostic data sent to manufacturer for review with no resolution provided.

I purchased my vehicle in July 2024 brand new. I started to experience an engine shudder at about 4500 miles with the truck coasting or on the accelerator around 1500 RPMs. It first began at lower speeds around 40 mph, but now I feel it at high speeds as well. I brought my truck back to the dealership three or four times and they told me that the shudder was due to the active fuel management…
I purchased my vehicle from Mak Haik Chevrolet 11711 Katy Fwy. Houston, TX 77079 on [XXX]. Approximately 4 months my Check Engine Light came on and I brought my Truck to Mak Haik Chevrolet to have it checked out. The Service Department could not figure out why the Check Engine Light had came on. They did complete the Recall N242435631 regarding a need to update the radio and serial communication…
my vehicle suddenly experienced decreased acceleration on the highway. A warning message appeared on the dashboard indicating reduced acceleration. When placing the vehicle in Reverse, the vehicle was not able to move in reverse. The dealership diagnosed it as a valve body needing replaced.
The truck failed go shift into reverse. Had to push the vehicle out of the parking space. When I tried to go forward the vehicle shuttered and then shifted into limp mode. Dealership has had the truck for over 8 weeks now and I am told there is a national back-order on the new valve body because of the number of trucks requiring replacements.
Vehicle would not go in reverse or shift out of First gear Diagnosed as needing a transmission valve body replacement
Transmission pauses from 1st and 2nd gear. Causing to have no acceleration from a stop. Can cause safety issue to accelerate while pulling in front of traffic. Truck has been to the dealer. Dealer says no codes triggered but the pausing still persists and is only getting worse. Truck has been doing it since around 30,000 miles. Truck currently has 36,760 miles.
Only 6k miles. Couldn’t go in reverse or get out of 1st gear. Brought to dealer, they said it needs a new valve body gor the transmission and there are so many trucks with this issue the part is on b/o for 2 weeks-3 months! In the meantime I have not truck.
Truck was purchased Aug 2024 During first few months, I felt a shudder/vibration when either holding speed and/or slightly accelerating between 30-45 mph, usually at 1100-1300 RPM. Current Odometer 33,995 In the last month the truck has began to vibrate worse. I have a "Rumblestrip" feeling when at the same speeds. More noticeable on surface roads when following behind traffic at 30-45 mph.…
hard/delayed shifting, slipping, shuddering , like rumble strips at certain speeds. Jerking, bucking, or significant delays when shifting gears. Shuddering/Vibration: A feeling like driving over rumble strips, especially at certain speeds and when warm
