- Reliability (3)3 out of 5 starsGMC generally offers good reliability, but some past Sierra models have had minor electrical or drivetrain issues. Long-term reliability expectations are solid, but not class-leading.
- Maintenance (3)3 out of 5 starsRoutine maintenance is on par with other trucks in its class. However, specialized off-road components on the AT4 trim might incur slightly higher costs for replacement or repair.
- Technology (4)4 out of 5 starsGMC's infotainment system is user-friendly and responsive, featuring a large touchscreen and wireless Apple CarPlay/Android Auto. Advanced driver-assistance features are plentiful and effective.
- Comfort (4)4 out of 5 starsThe cabin offers a comfortable and spacious environment, with supportive seats suitable for long journeys. Road noise is well-managed, contributing to a pleasant ride.
