2024 Gmc Sierra 1500 — Known Issues & Recalls

Your vehicle shut off unexpectedly while driving at 35 MPH and began shaking abnormally, with warning lights appearing on the dashboard. The engine would not restart after you pulled over. The dealer diagnosed that your engine had seized and requires replacement.

Your engine suddenly seized and stopped while you were driving, leaving you stranded in traffic for 2 hours. The engine had been inspected under a safety recall just 4 months earlier and passed after an oil viscosity change, but it still failed without warning. The engine had to be completely replaced at the dealership. This issue prevented the transmission from shifting out of park, trapping the vehicle on the roadway.

Your engine suddenly locked up and stopped working about 2 months after a recall inspection, with no warning lights or alerts beforehand. The dealer found that the lower end of the engine had failed and replaced the entire engine under warranty.

Your 2024 GMC Sierra's 3.0L Duramax Diesel engine failed at 57,000 miles with audible ticking and metal-on-metal grinding sounds, along with a noticeable loss of power. The dealer confirmed the engine is out of specification and requires a complete replacement. However, due to a high volume of similar engine failures, your replacement engine is on backorder with no estimated arrival date.

Your engine has failed and needs to be replaced at only 71,000 miles, just 90 days after your transmission was already replaced. This premature failure of major powertrain components suggests a significant underlying issue with your vehicle.

Your 6.2L V8 engine stalled while driving on the highway, and this happened twice within the first 25,000 miles of your new truck. Each time, the entire engine had to be replaced, with the second replacement taking nearly 6 weeks. The cause of the engine failures is not specified in this report.

While driving on the highway with cruise control engaged, your truck displayed a message telling you to push the start button. The transmission then downshifted violently multiple times, with the engine reaching 6000 RPM. The start button wouldn't shut off the engine until you pressed it several times, and then the truck wouldn't restart. At the dealership, the engine seized while being moved into the repair bay. You had already followed a recall procedure and switched to thicker oil as recommended, but the engine failure still occurred.

Your engine makes a rattling noise and stumbles intermittently, and the transmission shudders and shifts hard at random times. Sometimes the transmission stays at 2,000+ RPM for over two minutes. The dealer has been unable to replicate the problem despite seeing videos, and GM's suggested fixes (oil change and software updates) haven't resolved it. A scan found a loss of signal code to the transmission control module, but no repair was performed.

Your truck is displaying a 'Service Transmission' warning on the dashboard and experiencing rough shifting behavior—the transmission shifts slowly, sometimes jolts hard into gear, and makes unusual noises during gear changes. Acceleration feels jerky until the truck reaches a higher gear. The dealer was unable to reproduce the problem during testing and cleared the vehicle without service, though similar transmission issues have been reported in other trucks of this model and addressed through recalls.

Your transmission is experiencing repeated shuddering, hesitation, and slipping issues. After multiple dealer repairs—including replacement of the pressure control solenoid, valve body, and torque converter—the problem keeps returning, most recently with engine RPM fluctuating. The dealer has not yet inspected or repaired the latest occurrence despite the repeated failures within the first 3,000 miles.

Your transmission is shifting roughly and at highway speeds it feels like the torque converter is losing lockup, which affects power delivery and fuel efficiency. A service light appeared on your dashboard. This likely requires transmission fluid check, torque converter inspection, or transmission control module diagnostics.

Your 2024 GMC Sierra 1500 is unexpectedly shutting off while driving or sitting still with no warning lights, causing complete loss of electrical power and engine stall. Opening the door triggers an immediate drain on the battery that kills all power to the vehicle. Even after replacing the battery five times and the body control module four times, the problem continues to happen.

Your gauge cluster has stopped working, so you can't see your speed or fuel level. This is a safety concern since you're unable to monitor your speedometer while driving. The fix will likely involve diagnosing and repairing or replacing the gauge cluster circuit board or its electrical connections.

While driving at 65-75 mph, when you accelerate to pass another vehicle, your front brakes suddenly lock up for 1-2 seconds and your tires screech as they slide, before normal braking resumes. This has happened 4-5 times during recent trips, with or without adaptive cruise control enabled. The issue appears to be a malfunction in the braking system that needs urgent diagnosis to ensure safe operation.

Your front upper grille detached while driving at highway speeds and struck your hood, leaving scratches and a dent. The detached grille became a road hazard that could cause accidents. This same failure has been reported in 2022, 2023, and 2024 models, though GMC's current recall only covers 2022 vehicles, and the company has not offered warranty coverage for this issue.

Your rear lights have stopped working completely — you have no parking lights, tail lights, or brake lights in the back. This is a safety concern since other drivers won't be able to see your vehicle at night or when you're braking. The fix will likely involve checking the wiring, fuses, and bulbs in your rear light assembly.

Your truck's blind zone alert system — which warns you about vehicles in your blind spots — stopped working multiple times and needed several repair attempts before the problem was fixed. The dealership found that a faulty wiring harness was causing the system to fail, creating a safety risk during lane changes. The repeated visits to diagnose and repair the issue resulted in significant out-of-pocket costs. Fixing this issue involves replacing the wiring harness that connects the blind zone alert system.

While driving 65 mph on the interstate, your chrome grille deflector detached and flew off, hitting your windshield and passing over your truck. This created a hazard for other vehicles behind you, though you were able to maintain control. The mounting appears to have fractured, possibly due to a manufacturing defect similar to issues recalled in 2022 models. Repairing this will likely require replacing the grille deflector and its mounting hardware.

Your fuel gauge stopped working correctly and showed inaccurate fuel levels, causing your truck to nearly enter a reduced-power mode with a "Refuel - EMPTY Now" warning. The dealer diagnosed the problem as a failed DEF (diesel exhaust fluid) tank. The repair hasn't been completed because the replacement DEF tank is on backorder from the manufacturer.

Your front and rear backup cameras aren't working properly, and your side mirror turn signal indicators stay lit but don't function reliably. You're also experiencing glare coming into the cabin during nighttime rain driving. The dealer replaced the rear wiring harness and repaired the seat and transmission modules, but the problems came back. The fix may involve diagnosing and replacing the camera modules, wiring harness, or the vehicle's electrical control modules.
