2023 Chevrolet Silverado 1500 — Known Issues & Recalls

Your engine suddenly stopped working while you were driving on the freeway with no warning signs beforehand. The dealership confirmed this is a known issue affecting the 6.2L engine in your model year. You were able to safely pull to the shoulder, but you're concerned that Chevy may install the same engine and the problem could happen again. The fix will likely involve a complete engine replacement or repair by the dealership.

Your engine started making unusual noises and shutting off unexpectedly, with signs of locking up. This suggests internal engine damage or failure that requires professional diagnosis and likely replacement or major repair of engine components.

Your engine is making a loud, rhythmic metallic ticking or tapping noise from the top, which your Chevrolet dealer has confirmed. This noise is caused by manufacturing debris in the hydraulic valve lash adjusters that prevents proper lubrication of the valvetrain. This defect can lead to engine misfires, sudden loss of power while driving, and potential engine seizure — creating a serious safety risk, especially at highway speeds or during passing. The dealer is aware of this issue but has not addressed it with a repair or recall.

Your engine shut down while driving at 70 mph and displayed a "Hot Oil Shutting Down" message. The dealer found that the engine had failed completely and needs to be replaced. This happened after your truck was repaired under a recall campaign (25V274000) for engine and cooling system issues. The engine replacement should involve removing the failed engine and installing a new one.

Your 2023 Silverado 1500 has experienced multiple serious issues, including an abnormal engine sound and poor responsiveness while driving. Most critically, the cooling system has failed twice — causing the engine to overheat and triggering a "Reduce Acceleration" warning message — and there's an oil leak between the engine and transmission. Your instrument panel also goes blank intermittently, and the 360-degree camera stopped working (though this was repaired). Fixing these issues will likely require the dealer to replace cooling system components, reseal the engine-transmission connection, and diagnose the electrical problem causing the dashboard blanks.

While driving at 65 MPH, your truck suddenly lost power and displayed warning lights telling you it wouldn't exceed 55 MPH, then later 30 MPH. The dealer diagnosed a faulty DEF tank heater as the cause but couldn't complete the repair because the part is on national back order. The fix will require replacing the DEF (diesel exhaust fluid) tank heater.

While driving on the freeway, your transmission's valve body suddenly failed, causing the truck to lose power (feeling like it shifted into neutral) and the engine to rev to its maximum RPM. Your dealer confirmed this is a known issue and also needs to replace your Transmission Control Module, but both parts are on indefinite backorder. The repair will require replacing the transmission valve body and reprogramming or replacing the transmission control module.

Your truck is slow to engage when starting in cold weather, requiring several seconds before it moves. After driving at highway speeds, you hear clunking noises that sound like the transmission is shifting gears, but your RPM gauge doesn't change and the truck doesn't actually shift. These problems have gotten worse and happen more often over the past 6 months, though no warning lights appear on your dashboard. Your dealer diagnosed a failed torque converter and transmission valve body that need to be replaced.

Your transmission's valve body failed while you were driving, causing your truck to lose power and slow down significantly. Your truck's computer detected the problem and displayed error code P0747. The valve body will likely need to be replaced or rebuilt to restore normal transmission operation.

While driving on the interstate at 55 mph, your truck's throttle became unresponsive with no engine response. The engine then shut off completely and the transmission shifted into neutral, with no ability to restart. You were able to safely coast to the shoulder, but you had no warning and no way to safely limp the vehicle to reduce speed during this complete loss of power on a busy highway. The dealer may need to replace the engine and diagnose the underlying electrical or fuel system failure that caused the sudden shutdown.

Your truck lost power and entered limp mode on March 3rd. The dealership found metal contamination in the engine and returned it on March 17th, but the truck never drove properly afterward. It broke down again on March 20th, and they discovered the throttle body was faulty—a problem they should have caught during the first repair. You're concerned this may be a recurring issue with this model.

Your truck's tailgate opens by itself while parked, even though you're not pressing any buttons on the key fob or inside the truck. This random opening is draining your battery. The issue appears to be an electrical malfunction causing the tailgate latch to unlock unintentionally.

Your truck's battery keeps dying and has required 4 replacements in 4 months. You believe the power tailgate release system may be draining the battery when the truck is off. A mechanic should check the tailgate's electrical circuit for a parasitic drain and repair or replace the faulty component.

Your engine suddenly shut down completely while driving 60 mph on a highway, leaving you with no power to steer or accelerate — a serious safety risk with traffic around you. The engine wouldn't restart and the vehicle appeared to shift to neutral automatically. Your dealer confirmed the engine is covered under warranty and GM is sending a replacement engine, but as of your report, it hadn't arrived nearly a month later.

While driving on the highway, your truck's message center told you to restart and shift to neutral, but then said conditions weren't right to shift. You lost power steering and brakes, and after turning the truck off, it wouldn't restart — the lights flickered and the starter wouldn't engage. The tires seized up during towing, and the emergency brake kept resetting itself. The dealership found catastrophic engine failure at under 24,000 miles. This is your second major engine problem (the first involved collapsed lifters at 5,000 miles), raising serious concerns about the vehicle's reliability and safety. Repairs will likely require a complete engine replacement, though you've noted other owners report similar issues with replacement engines.

While driving at 75 MPH, your engine started running rough and shaking, then lost power and made a loud bang before the engine failed completely. The transmission also showed fault codes during diagnosis. Even though there's a related recall campaign, your vehicle's VIN wasn't included in it. The engine will likely need to be replaced or rebuilt, and the transmission may need inspection or repair.

After the recall service on your 6.2L engine, your fuel economy dropped by 5 miles per gallon with no changes to your driving habits or fuel type. You've consistently monitored your fuel mileage and noticed this decline started immediately after the recall was performed. The dealer may need to review the recall work and engine tuning to identify whether the service affected fuel efficiency settings.

Your DEF (diesel exhaust fluid) gauge isn't working correctly. After filling the DEF tank, the gauge won't show it's full, and it sometimes reads over half full but then suddenly shows empty within minutes, triggering a limp mode warning even though DEF is actually present. Your truck has also gone into limp mode while the DEF tank was actually full. The fix likely involves diagnosing the DEF level sensor, which may need cleaning, recalibration, or replacement.

Your truck's tailgate has opened unexpectedly while driving. The tailgate latch switch turns on and off repeatedly when the vehicle is parked, which is draining your battery. This is a safety concern since an open tailgate while driving can be hazardous.

Your truck's dashboard repeatedly displayed false warnings that your Diesel Exhaust Fluid (DEF) was low and needed refilling, even though the DEF system was actually fine. These warning messages caused your instrument panel to freeze and stop working properly, and they also prevented you from refueling your diesel tank because the system thought it was full. A dealer diagnosed this as an electrical glitch, reset the vehicle to fix it, and confirmed there was nothing wrong with the DEF system itself. The fix likely involved a software update or electrical system repair related to the DEF level sensor or warning system.
