2023 Chevrolet Silverado electrical system problems

“Cluster screen is blinking and not showing speed or anything else. I did take it to the dealership they tried to reset it but that didn't work, I did talk to someone when I called the gm line but they said since I was a lil over t he warranty it was nothing they could do. GM help desk I believe, but I'm sure if the day is bot correct they have the call recorded to get the correct time and day”

“This truck and hundreds, if not thousands of others has many issues with the electronic shifter. Not only do they frequently fail, but Chevrolet does not have any parts available to the dealerships for weeks. These Duramax 3.0 diesel engines are also a huge problem with the emission system and DEF. They constantly fail and we are spending thousands to repair. My truck is stuck at a dealership in [XXX]. I had to rent a vehicle to drive back home to [XXX]. The dealer has no idea how long it will take to get a shifter from Chevy. Is there any help available. Why aren't these shifters under a major recall? I am literally stranded after paying $65,000 for a truck!”

“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.
