2023 Chevrolet Silverado 1500 electrical problems

ELECTRICAL SYSTEM

A valve on the 3.0L Duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for GM and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that GM knows is their fault.

“Service transmission now unable to shift soon” message. Vehicle is stuck in park. Message appeared in May. Transmission stuck shortly after. Safety is at risk due to transmission being unable to shift due to faulty module that is widely reported and known to Chevrolet.

6/12/26 ( 2023 Chevy Silverado - 6.2 liter engine) While driving at approximately 40 MPH on a two lane road, the truck shut off. After multiple attempts, the engine failed to restart. The transmission locked up in park and would not release. This required the truck to be dragged up on the flat bed wrecker instead of rolling freely. Prior to this instance there have been several issues with the electrical system. 1. radio sound shuts off. does not come back on. 2. Head lights stay on for 10 minutes after vehicle is turn off. 3. Tail gate opens on it own. Tail gate doesn't open with fob. 4. door locks fail to operate correctly. 5. When drivers door is opened a beeping sound starts and doesn't stop until door is closed. I have reported these problems to GM & have two case numbers. The dealership reports that the 6.2 replacement engines have had multiple failures.

My 2023 Chevrolet Silverado 1500 experiences an intermittant, uncommanded mechanical drivetrain lockup and severe binding when accelerating from a complete stop. The vehicle rolls fine in a straight line for several feet, but the exact moment the steering wheel is turned slightly (a couple degrees), the drivetrain violently binds up. This creates resistance in the steering and acceleration, as well as a severe physical and audible metallic clunking slam and massive shockwave vibrations felt directly through the steering wheel, floorboards, brake/gas pedals, and driver’s seat. During the last event, the vehicle threw a "Service 4 Wheel Drive" dash message and refused to shift out of "Auto" mode back into 2WD. Because this is a pure mechanical interference/binding issue, it does not consistently throw active electronic trouble codes. A standard OBD2 code scan will show nothing. After turning the vehicle off for several hours and testing again, the problem persisted. After towing the vehicle to a dealership (6/10/2026) it sat for at least 5 days before dealership service looked at it. By this time, the active warning lights cleared. My initial servicing dealership refused to perform physical hardware or fluid diagnostics under my factory warranty, stating they would not look at the vehicle unless I paid $860 out-of-pocket or until the drivetrain "completely grenaded" on the road. Because this uncommanded lockup restricts my ability to steer the vehicle safely from a stop, it presents an immediate crash hazard. At the direction of General Motors Corporate, I am escalating this issue and moving the vehicle to a secondary certified facility (Feldman Chevrolet of Novi) on June 23, 2026, for a formal physical hardware and fluid tear-down inspection.

ON MONDAY, 6/15/26, WITH APPROX 45,400 MILES, I WAS DRIVING DOWN THE ROAD AND TRUCK SAID SERVICE TRANSMISSION. THE GEARS WOULD SHIFT, BUT IT LAGGED A LITTLE BIT. I SCHEDULED AN APPT FOR TWO DAYS LATER, AND ONLY DROVE IT WHEN I ABSOLUTELY HAD TO, WHICH WAS ONLY TWICE BEFORE MY SCHEDULED APPT. I GET IN IT TO DRIVE AND IT SAYS SERVICE TRANSMISSION- UNABLE TO SHIFT SOON, THEN ON MY WAY TO THE DEALERSHIP, IT SAYS ALL OF THAT, PLUS SERVICE DRIVER ASSIST SYSTEM. CHAVY'S QUALITY ASSURANCE TEAM NEEDS TO GET IT TOGETHER! THIS IS ABSOLUTELY RIDICULOUS.

In 2024 there was a recall for the tailgate locking mechanism - We did not receive that recall - but the part went bad causing the battery to drain - and it had to be repaired. We had to pay for the service $500.00 - We I asked the dealership about this recall they said it did not include my vehicle. But it was indeed that part that went bad. I lease the truck - I had every intention of purchasing after the lease - I am over the miles and was told it was out of warranty. I certainly would not complain about paying for it - but there was a recall last year for said part. Could some please reach out to me regarding this - Thank you

ELECTRICAL SYSTEM

Vehicle has experienced repeated electrical and safety system failures since purchase in 2023. Affected systems include forward collision warning, blind spot monitoring, parking sensors, cameras, and infotainment. Failures include complete loss of camera functionality (rear and front), infotainment system shutdowns or resets while driving, loss of audio, and volume malfunctioning (including sudden increases or no response). The vehicle has also generated false safety alerts, including forward collision warnings and blind spot alerts when no hazard was present. These issues have occurred while the vehicle was in operation, creating safety risks due to loss of visibility systems and unreliable warning alerts. In multiple instances, the system would become completely non-functional for extended periods, sometimes lasting days or weeks, before temporarily returning. The problem has been reported to a dealership multiple times and has been inspected and serviced. Repairs have included software updates and component-related work; however, the issues have continued to persist or reoccur. The failures are intermittent but recurring and have not been permanently resolved despite multiple repair attempts. The condition reduces driver confidence and creates unsafe operating conditions due to unreliable safety systems and loss of critical features while driving.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that on two separate occasions while hauling the camper, the "High Diesel Exhaust Fluid", Exhaust Fluid Range", and "Fill DEF (Diesel Exhaust Fluid) Now" warning messages were displayed on the instrument panel. The messages indicated that the Diesel Exhaust Fluid was low and needed to be replenished. The contact stated that the failure caused the instrument panel to freeze and not operate as needed. Upon attempting to refuel the vehicle, fuel failed to enter the fuel tank since the diesel tank was full. The vehicle was taken to a dealer, where the contact was informed that the failure was an electrical glitch and that there were no issues with the Diesel Exhaust Fluid system. The contact was also informed by the dealer of Technical Service Bulletin: 22-NA-150, which the contact related to the failure. The dealer reset the vehicle, which caused the instrument panel to return to normal operation. The manufacturer was then notified of the failure, and the contact was informed that vehicle was not included in the TSB. The contact was given a case number and was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 55,000.

Dear Sir or Madam, I am writing to formally report a safety-related defect involving the power unlatching tailgate switch on my Chevrolet 1500 truck and to request that this make and model be added to the current safety recall affecting Chevy HD vehicles. The power tailgate unlatching switch malfunctioned and would repeatedly attempt to open and close the tailgate while the truck was parked. On one occasion, this occurred continuously overnight. The following morning, my key fob was completely unresponsive, and the truck had zero battery life. The battery would not accept a charge, and the vehicle had to be towed to the dealership. Upon inspection, the dealership confirmed that the battery had been fully depleted and permanently damaged due to a short in the power tailgate switch. The faulty switch continuously drew power as it attempted to actuate the tailgate, ultimately destroying the battery. This failure created a serious safety and reliability concern, leaving me stranded with a completely inoperable vehicle. Given that this issue resulted from an electrical short and caused total battery failure, I believe it represents a significant safety defect. Based on the similarity to issues addressed in the current Chevy HD safety recall, I strongly believe this make and model should be included in that recall. I respectfully request that this matter be reviewed and addressed to prevent other owners from experiencing the same hazardous situation. Thank you for your time and attention to this matter. I look forward to your response. Sincerely, Charles Senn

My telematic control module has intermittent connectivity. The check engine light comes on and off and the go's, on star and wifi comes and goes as well. This vehicle has 52k miles on it and is only 2 years old. The shop I took this to said it is VIN specific so the dealer is the only place that can fix it. This is a safety issue due to no onstar as onstar claims to be a safety feature. This needs a recall because this issue is all over the place on gm products.

I am filing this complaint against General Motors (GM) and its affiliated dealership Kunes Chevrolet for the unauthorized installation of a surveillance/tracking device (LoJack) in my vehicle, which resulted in severe personal harm, digital exposure, and downstream targeting. On [XXX], I purchased a 2023 Chevrolet Silverado from Kunes Chevrolet in Morrison, Illinois. I was never informed that a LoJack tracking device had been installed in the vehicle. On [XXX], I appeared in person at the same dealership to confront suspicious activity tied to my vehicle’s GPS data. A service advisor confirmed the presence of a LoJack unit and printed a removal ticket, which should be recorded in GM’s internal service system under my name and VIN. This constitutes verifiable, documented acknowledgment of the unauthorized installation. Consequences of This Violation Include: •Illegal geolocation tracking without consent •Suspected sale or exposure of my driving data to third parties and possible defense-linked contractors •Multiple impersonation attempts, including suspected social and professional infiltration •Psychological harm, loss of employment, opportunities, and repeated digital sabotage •Multiple homicide attempts on my life •FOIA-confirmed military interest in my location (Air Force Case #: [XXX]) •IRS and identity manipulation, suggesting systemic misuse of my physical address, GPS logs, and digital footprint INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
