What owners report
Complaints on this model year cluster heavily around engine problems — ranging from stalls and loss of power to seized engines replaced by dealers — and a second cluster around rough or harsh shifting transmissions. A further group covers electrical and infotainment faults: radios that go silent, cameras that quit, and OnStar/navigation issues. Most of these are reported on relatively low-mileage, recently purchased trucks, so buyers should go in already knowing what to check and ask.
- Engine
Engine failure, knocking and sudden loss of power
- 42 complaints (34%)
- median 23,867 mi at 1.0 yrs old (6 state mileage, few)
- filed 2025–2026
Complaints describe the engine making loud knocking or rattling noises before losing power, and in several cases the truck shutting down completely and needing a tow. Dealers reportedly diagnosed bearing wear, metal in the oil, or an engine failure, and told owners a replacement engine was required. Owners describe waiting weeks or longer for engines, and some note that the failure occurred without any prior warning light. Reports range from a few thousand miles to around 35,000 miles, with several owners describing the failure during highway driving.
What to check: Ask whether the engine has already been replaced or inspected, and request service records showing oil changes and any bearing or metal-in-oil findings. Listen for a knock at cold start and on a highway test drive.
2 excerpts from owner complaints in NHTSA records
“2025 GMC Sierra 1500 has had 2 engine failures since purchase date June 2025. Engine failed on a road trip with my family, leaving me stranded for hours. After the problem being resolved, engine failed once again after 5 months. On the dash it said loss of power and wouldn’t crank to turn ON”
NHTSA complaint #11717554, filed 2026-02“I purchased a 2025 GMC Denali a few months ago. At approximately 7,000 miles, the front brakes failed unexpectedly and were replaced by the dealership. However, by 14,000 miles, I began experiencing brake issues again. Before I could return the vehicle for service, I was driving on the turnpike when the engine suddenly seized without warning. This created an extremely dangerous situation—vehicles behind me nearly collided as I lost power and control. …”
NHTSA complaint #11688037, filed 2025-09 - Vehicle speed control
Unexpected acceleration or cruise control engaging at low
Mentioned in 7 of 60 sampled complaints
Complaints describe the truck surging forward uncommanded — in one case while idling in park, in others while maneuvering at walking pace — and cruise control setting itself to roughly 15 mph when the wheel toggle is bumped during parking. Owners report the incidents as intermittent and say dealers could not duplicate them or found no stored codes. Reported at low mileage, typically during parking, turning, or other low-speed maneuvering.
What to check: Check how the cruise control toggle behaves at very low speed and whether the feature can be disabled. Ask whether the dealer has any record of a reported surge complaint for that truck.
2 excerpts from owner complaints in NHTSA records
“Cruise control activates at speeds between 1-5mph, which frequently happens while turning, parking, or going through a drive-through. The cruise control activates by a toggle on the left spoke of the steering wheel, which can be easily bumped while doing low-speed maneuvers like parking. When bumping the toggle, the cruise indicator shows a set speed of 15-18 mph, and the vehicle surges forward trying to attain that speed. …”
NHTSA complaint #11758980, filed 2026-08“2025 GMC Sierra 1500 shifted from Park to Drive uncommanded, accelerated uphill, and crashed while idling, keyfob outside of vehicle, March 2025. ESIS couldn't replicate and falsely claimed I didn't put it in Drive, despite photos and no one inside.”
NHTSA complaint #11656822, filed 2025-04 - Transmission and drivetrain
Harsh shifts, shudder and transmission limp mode
- 11 complaints (9%)
- median 34,637 mi at 1.0 yrs old (1 states mileage, few)
- filed 2025–2026
Owners describe harsh or delayed shifts, a shudder or vibration at highway speed, and occasionally a transmission warning that puts the truck into a reduced-power mode. Some complaints mention the truck shifting oddly between two gears, and dealers were reported as unable to duplicate the complaint or as having no codes to act on. A few describe long waits for replacement parts once a fault was confirmed. Reported across a wide mileage range, from a few thousand miles up to around 75,000 miles, and often felt at highway speeds.
What to check: Test drive at highway speed and feel for shimmer or vibration through the seat and wheel, and note shift quality when slowing and accelerating. Ask whether any transmission diagnostics or software updates have been done.

“The truck keeps wanting to engage two gears acceleration and deceleration and still is happening i have taken it to the dealership an they can not find a problem took it home an its happening again so now its back at the shop now I'm waiting to hear back from them so this is the second time to the dealership”
NHTSA complaint #11718159, filed 2026-02“One evening while driving home from work, the transmission warning light illuminated on my dashboard, indicating that the vehicle would soon stop. The notification specifically stated there was a transmission problem. The following morning, I brought my truck to GMC for service. After running a diagnostic, GMC confirmed an issue with the transmission. A few days later, GMC informed me that they were waiting for a replacement part to arrive. The part did not arrive for almost a month. …”
NHTSA complaint #11758808, filed 2026-08 - Electrical system
Radio and audio cuts out or goes silent
Mentioned in 4 of 60 sampled complaints
Complaints describe the infotainment screen blanking at startup, losing radio or volume controls, and at times all interior audio including turn-signal chimes going silent for hours. Owners report visiting dealers repeatedly with the problem returning, and in some cases a reset or a software-related bulletin was applied. Others describe radio buttons on the wheel or dash becoming unresponsive. Mostly reported on vehicles with only a few thousand miles, often soon after delivery.
What to check: During a test drive, check the screen, volume, and turn-signal chime, and try a wireless phone pairing. Ask whether software updates or radio resets have already been performed.

“Got in started Truck and there is no Sound anywhere... none for blinkers, radio, warning lights if there to be any. ZERO sounds. This has been investigated by Hertrich Service--showed video of no sounds coming from truck speakers at all. This is safety hazard with no audio warnings or blinkers, flasher sounds at all.”
NHTSA complaint #11734260, filed 2026-04“The vehicle will loose all interior audio to include stereo, turn signals, and all other audio safety features for several hours at a time. GMC has done three repairs and still no resolution. Lack on audio impacts the safety of the vehicle. Has happened dozens of times and appears to be larger GM issue that is u resolved. Has occurred at least 20 times since I bought the vehicle 10 months ago.”
NHTSA complaint #11695335, filed 2025-10
Buying note. Records for the truck matter more than usual here: ask for engine and transmission service history and whether any software updates have been applied. A thorough highway test drive covering shift quality and cruise control behavior is worthwhile, and a pre-purchase inspection with an oil check is sensible.
Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
