The fourth-generation GMC Sierra was introduced for the 2019 model year and is still being sold today. Upgraded with a new look, improved powertrains, and modern tech like Apple CarPlay and backup cameras, the 4th generation GMC Sierra has become a very popular truck, alongside the Chevrolet Silverado which got similar updates. With that said, owners and buyers should be aware of some common issues on the GMC Sierra 4th generation truck, to plan for future maintenance and potential repairs.
Transmission Issues
One of the most commonly reported issues on the GMC Sierra 4th generation relates to its 8-speed automatic transmission. Many owners have reported hard shifts, hesitation, or a shuddering during acceleration. While GM has issued updates and service bulletins to address these problems, it’s an issue that can resurface without regular servicing and proper fluid maintenance.
Brake System Problems
A number of GMC Sierra trucks have experienced premature wear on braking components. Owners have reported squealing, vibration during braking, or reduced brake performance earlier than expected. Staying on top of inspections and replacing brake pads and rotors at the proper intervals is key to avoiding more expensive brake repairs.
Engine Concerns
Some owners have experienced oil consumption issues, rough idling, or occasional stalling. These concerns are not widespread but highlight the importance of regular maintenance and oil checks, especially for trucks used in heavy-duty towing or off-road conditions.
Suspension and Ride Quality
The GMC Sierra 4th generation offers a smoother ride than many older pickups, but owners have noted issues with suspension components over time. Problems include premature wear of shocks or bushings, leading to clunking noises or a rougher ride. Given the Sierra’s size and workload, suspension upkeep is essential.
The Importance of the GMC Sierra Maintenance Schedule
While these common issues can cause some concern, regular service can help prevent minor problems from turning into major repairs. Following the GMC Sierra maintenance schedule is the best way to extend your truck’s reliability. This includes regular oil and filter changes, brake inspections, tire rotations, fluid checks, and more. By keeping up with routine maintenance, you’ll not only improve performance but also protect your investment.
