In this guide, we’ll break down the most frequent complaints, share relevant technical service bulletins (TSBs) and recalls, and explain how warranty coverage—especially extended coverage—can protect you from costly out-of-pocket repairs.
What to Watch for as Your Truck Ages and How to Avoid Expensive Repairs
The 2023 GMC Sierra 1500 is a refined, full-size pickup that blends rugged performance with upscale amenities. It’s a truck that appeals to both hardworking contractors and tech-savvy commuters—thanks to its broad trim lineup, multiple engine options, and advanced driver assistance systems. But as more owners put miles on their 2023 Sierras, a few common problems are beginning to surface.
Whether you drive an AT4, Denali, Elevation, or SLT, understanding 2023 GMC Sierra 1500 problems is critical if you want to stay ahead of repairs and keep long-term costs under control. In this guide, we’ll break down the most frequent complaints, share relevant technical service bulletins (TSBs) and recalls, and explain how warranty coverage—especially extended coverage—can protect you from costly out-of-pocket repairs.
As a carryover from the 2022 refresh, the 2023 Sierra 1500 builds on GM’s effort to modernize the truck lineup with a more upscale interior, improved infotainment interface, and smoother ride quality. However, real-world use is revealing a few weak points across trims and engine types.
Some owners have reported drivetrain concerns, while others have noted glitches in the infotainment or electronic systems. Though many of these issues fall within the scope of the factory warranty, some don’t—and once the bumper-to-bumper coverage ends at 36,000 miles, repairs can get expensive quickly.
Here are the top issues reported by owners, dealerships, and technician networks as of early 2024:
Problem Area | Description | Affected Models |
10-Speed Transmission | Jerky upshifts or clunky downshifts under light throttle or low-speed load | 5.3L and 6.2L V8 trims |
Infotainment Freezing | Touchscreen becomes unresponsive, lags, or randomly reboots | SLT, AT4, Denali |
Camera System Faults | Backup camera delay, distorted image, or blank screen | All trims with HD camera |
Steering Feel or Noise | Slight clunking or vibration through the steering column over bumps | All trims |
Electronic Parking Brake Faults | Warning light randomly appears or system fails to engage | Denali, AT4 |
These issues are most likely to appear after the first year of ownership—right around the time drivers begin nearing the end of the 36,000-mile bumper-to-bumper warranty.
GMC has issued several bulletins and recalls that confirm these problems. Here are the most relevant ones for 2023 Sierra 1500 owners:
These TSBs and recalls confirm that GM is aware of several electronic and mechanical issues affecting this model year.
Every 2023 GMC Sierra 1500 comes with standard factory warranty protection. However, the length and scope of coverage vary by component:
Warranty Type | Coverage Duration |
Bumper-to-Bumper | 3 years / 36,000 miles |
Powertrain (Gas Models) | 5 years / 60,000 miles |
Powertrain (Diesel) | 5 years / 100,000 miles |
Roadside Assistance | Matches powertrain duration |
Corrosion Protection | 6 years / 100,000 miles |
While this coverage is solid during the first few years, it doesn’t last long enough for most long-term owners. Bumper-to-bumper coverage expires just as electronic systems—like cameras and infotainment—start to show problems.
Once your truck is past the 36,000-mile mark, most non-powertrain repairs are your responsibility. Unfortunately, some of the most common Sierra 1500 issues fall into this category.
Repair Type | Average Cost | Covered Under Factory Warranty? |
Infotainment unit replacement | $1,200–$1,500 | No (after 36k miles) |
Camera module repair | $800–$1,100 | No |
Steering column assembly | $1,400+ | No |
Parking brake module | $1,000+ | No |
Transmission valve body | $3,000–$4,000 | Yes (under 60k or 100k miles) |
As trucks age, issues with electronics and advanced driver assist systems tend to become more frequent—and more expensive to repair.
Owner forums and service records show a consistent pattern of infotainment problems, transmission roughness, and sensor glitches. Many owners praise the overall drive quality and capability of the 2023 Sierra 1500, but note that reliability concerns grow once factory coverage expires.
One owner on a GMC forum shared:
“Love the Denali Ultimate, but already had the infotainment freeze twice on long trips. Dealer did a reset but said it might come back unless I update the software again.”
Another technician added:
“We’re seeing early camera faults and transmission complaints on the new 1500s—same problems as the 2021–2022 models. Most of it’s minor, but without warranty coverage, the bills add up fast.”
If you plan to keep your Sierra beyond 36,000 miles—or rely on it for daily driving, towing, or long road trips—extended protection is more than worth it. High-end trims come loaded with expensive components that are increasingly prone to failure as the vehicle ages.
Infotainment and camera systems alone can cost thousands to repair. Throw in any drivetrain or electrical failure and the repair bill could easily exceed the cost of an extended warranty.
