2024 Chevrolet Silverado 2500 Problems

What owners report

Owners of this model year most often write about electrical and trailer-towing problems: the truck intermittently drops the trailer brake connection while towing, and audio/multimedia systems sometimes go silent or lose sound. A second cluster of complaints covers hard or violent transmission shifts and occasional reduced-power events, typically reported well past 50,000 miles. Brake and steering complaints appear at very low mileage, and some lighting faults are reported after the warranty period.

1. 1
   Electrical system

   Trailer brakes disconnect or drop out while towing

   • 49 complaints (34%)
   • median 2,000 mi at 0.5 yrs old (9 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2023–2026

   Owners towing travel trailers and fifth wheels describe a "Check Trailer Wiring" or "Trailer Brakes Disconnected" message that appears and clears repeatedly, and the trailer brakes stop working each time it appears. The message is often intermittent, and several owners say the dealer could not duplicate or locate the cause. Some owners report the trailer brake control module was replaced, with the message returning afterward; others note the truck works fine with a different trailer or that the trailer brake lights stayed on after shutdown. Commonly reported within the first few thousand miles of towing, in some cases on the first trip with a trailer.

   What to check: If you tow, hitch up a trailer and watch the driver information center for disconnection messages over a full drive. Ask the seller whether any trailer brake wiring or module work has been done.

   “While pulling my Vilano fifth wheel trailer to Alabama from my home state of Texas the driver information center alerted me that the trailer brakes were disconnected. Then a short while later it alerted that trailer brakes were connected. This situation continued for the entire trip to Alabama. When the info center indicated trailer brakes were disconnected, they were indeed not working. Several times I almost rear ended cars stopping in front of me. …”

   NHTSA complaint #11664955, filed 2025-06

   “While towing our 25ft travel trailer, I began getting warning from the trailer brake controller which repeatedly disconnected and, thankfully reconnected them after a brief interval. Luckily, the times when I had no trailer brakes did not require rapid stops. That said, towing a 7000 # trailer thru the mountains in a driving rain storm with no brakes randomly caused a bit of concern. After researching this I find this is a known defect and has TSB’s and voluntary recalls in place. …”

   Transmission and drivetrain

   Hard or violent transmission shifts; valve body faults

   • 33 complaints (23%)
   • median 54,500 mi at 1.8 yrs old (4 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2024–2026

   Owners describe harsh downshifts when slowing or exiting a highway, jolts during upshifts between roughly 50 and 60 mph, and in some cases rear-wheel lockup or a sudden loss of power with a "reduced acceleration" message. Several complaints state the dealer diagnosed a failed transmission valve body or shift solenoid plate, and some note the part was on back order for weeks. A few owners report the same symptoms returned after the valve body was replaced and reprogrammed. Reported from a few dozen miles up to about 60,000 miles, often while towing or under load.

   2 related service bulletins

   What to check: Test drive at highway speed and on a downgrade, feeling for harsh downshifts or lurches. Ask whether the transmission valve body has been serviced or replaced and request any repair records.

   “The transmission valve has gone bad a few thousand miles outside of warranty. This part has widely been recalled in Silverados up to 2022 but is not including 2024 yet. This is the same issue, that I also had with my Chevy Tahoe last August. Please include 2024 2500 Silverados.”

   NHTSA complaint #11710458, filed 2026-01

   “Transmission failure on interstate i90, truck down shifted violently and check engine light came on and warning on dash read speed reduced drive with caution. Took truck to gm dealer on August 1 2024 who said the transmission shift solenoid plate has to be replaced. Gm dealer still has my truck as of October 16 2024 and all I they can tell me is that the part is on back order and they have no idea when it will be available. …”

   Engine

   Stalling or stalling-like power loss while driving

   • 9 complaints (6%)
   • median 3,200 mi at 0.1 yrs old (2 state mileage, few)
   • filed 2023–2026

   Owners report the engine shutting off or losing power while driving, with multiple dash warnings and little or no brake and steering assist, and in some cases the truck would not restart. Dealer findings in the complaints vary, including a chafed engine-compartment wire, a failed fuel pump power control module, and collapsed lifters requiring engine repair. Several of these events occurred while towing a trailer. Reported from near-new mileage (under 1,000 miles) up to about 19,000 miles.

   2 related service bulletins

   What to check: Ask for the full service history and whether any stalling, charging or engine repair has been recorded. Have a mechanic inspect engine-compartment wiring for chafing and check for stored fault codes.

   “With 19,000 miles on my Silverado 2500 HD I was traveling down a hill towards a stop sign at a T intersection. About 100 yeads from the stop sign I had many flashing errors on the dash, very little brake and very little steering. The engine just shot off. Fortunately I was able to stop the vehicle right at the stop sign while traffic from right and left had no stop sign. The truck would not start after. It did have electrical power. I tow was needed. The next day the Chevy dealer did find a bulletin for a wire in the engine compartment chaffed. …”

   Exterior lighting

   Turn signal and exterior lamp faults after warranty

   • 5 complaints (4%)
   • median 68,620 mi at 2.1 yrs old (2 state mileage, few)
   • filed 2023–2026

   Owners describe a "Check Front Turn Lamp" or "service turn lamp" message with fast flashing, and in some cases the turn signal stops working until the vehicle is shut off and restarted. Some report that all exterior lights flickered on and off intermittently while driving after software programming work. Complaints state the repair is a full headlight assembly replacement and that a software reflash did not resolve the message. Mostly reported from roughly 60,000 to 78,000 miles, often outside the warranty period.

   2 related service bulletins

   What to check: Operate each turn signal and tester lamps on the test drive and watch for fault messages or hyperflash. Ask whether the headlight assemblies have been replaced and whether any warranty coverage remains.

   “I was making a right turn and my signal started flashing faster than normal and stated service passenger front turn lamp. There is no way of service without replacing the entire headlight which is $2000.00 for one side. Took to gm dealer about a month ago to diagnose the opposite side and they stated warranty will not cover it. The truck had approximately 76k miles on it when the driver side was looked at and the passenger side was with 78k miles. I have contacted gm warranty claims department twice now to put it all on record. …”

   • 5 complaints (4%)
   • median 31,200 mi at 1.5 yrs old (2 state mileage, few)
   • filed 2025–2026

   Owners report that on some starts there is no sound at all from the radio, turn signal clicks, or warning chimes, and that sound sometimes returns after a shutdown and restart. In one complaint the dealer described it as an intermittent loss of audio and it was not repaired. Related complaints describe wireless phone projection failing to connect until the key is cycled, and slowness or reset issues with the infotainment screen. Reported in the first weeks of ownership and intermittently thereafter, with no clear mileage pattern.

   4 related service bulletins

   What to check: Start the truck several times during a test drive and confirm radio, turn signal and chime sound work. Ask whether any radio or software updates were performed.

   “I bought my track about a year ago. Within the first week of owning it. Multiple times a week, when I start it there is no sound. No radio, music, blinkers, etc. Absolutely no sound. Some of the time once I get to where im going, turn it off. Once I start it again it's back. The other times takes a couple times to hear it again. When I asked the dealership, I was told it's a known issue. 9 months later it still does it. Some weeks once or twice. Other weeks up to 10 times. …”

Buying note. This model year attracts complaints about trailer brake disconnects, transmission shift quality and intermittent electrical faults, so a thorough test drive while towing and a check of service records matters more than usual. Ask specifically what warranty remains and whether any bulletins or programming updates have already been applied.
