2024 GMC Sierra EV
Here’s a breakdown of reported issues and complaints for the 2024 GMC Sierra EV, categorized by major component. Given that the 2024 Sierra EV is a relatively new model, widespread, statistically significant data on common issues is still emerging. This information is compiled from early owner reports, forums, and automotive news.
The 2024 GMC Sierra EV marks GMC’s entry into the electric pickup truck market. The initial launch features the Edition 1 model, boasting an estimated 754 horsepower and 785 lb-ft of torque in Max Power mode. Future trims will offer varying power outputs and battery ranges. Owners are drawn to the Sierra EV for its futuristic design, impressive performance, and advanced technology, including the Super Cruise driver-assistance system. However, some early adopters have expressed concerns about software glitches, availability of charging infrastructure, and build quality issues, similar to those experienced with other first-generation EVs.
Electric Motor
Electric Motor (All Trims)
- High Pitched Sound at Certain Speeds
- Description/Symptoms: Owners have reported a high-pitched whine or noise emanating from the electric motors at certain speeds, typically between 30-50 mph. The noise is intermittent and doesn’t seem to affect performance, but is considered an annoyance.
- Solution: Diagnosis by a GMC service technician is required to pinpoint the source of the noise. Potential fixes could involve motor mount adjustments, component replacement, or software updates related to motor control.
- Estimated Cost to Fix: Unknown (likely covered under warranty for early issues).
- Recalls: None Found
Battery/Charging System
Battery/Charging System (All Trims)
- Inconsistent Range Estimates
- Description/Symptoms: The estimated range displayed on the dashboard can vary significantly from actual driving range, especially in cold weather or when towing. Owners report discrepancies between the indicated range and the miles they are actually able to drive before needing to recharge.
- Solution: GMC has indicated that range estimates can be affected by driving habits, temperature, and load. Software updates to refine the range estimation algorithm may be released. Drivers can also improve range by driving conservatively, preconditioning the battery, and minimizing accessory usage.
- Estimated Cost to Fix: Software updates should be covered under warranty. No cost.
- Recalls: None Found
- Slow Charging Speeds at Public Charging Stations
- Description/Symptoms: Some owners have reported slower-than-expected charging speeds at certain public charging stations. This can be due to issues with the charging station itself, or incompatibility between the vehicle’s charging system and the station’s hardware.
- Solution: Try a different charging station. Report the issue to the charging network provider. If the problem persists, a GMC technician can diagnose the vehicle’s charging system.
- Estimated Cost to Fix: Varies. Potential replacement of charging port components. Could be covered under warranty.
- Recalls: None Found
Suspension
Air Ride Adaptive Suspension (Edition 1)
- Air Suspension Failure
- Description/Symptoms: Air suspension system malfunctions leading to uneven ride height, compressor failure, or complete system failure causing vehicle to sag.
- Solution: Diagnosis by a certified technician. Air compressor and/or air strut replacement.
- Estimated Cost to Fix: $2,000 - $4,000+ (depending on components needing replacement).
- Recalls: None Found
Electrical
- Infotainment System Freezing/Crashing
- Description/Symptoms: The infotainment system occasionally freezes or crashes, requiring a restart. This can disrupt navigation, audio, and other vehicle functions.
- Solution: Software updates from GMC are expected to address these issues. A temporary workaround is to restart the system by holding down the power button.
- Estimated Cost to Fix: Software updates should be covered under warranty. No cost.
- Recalls: None Found
- Super Cruise Malfunctions
- Description/Symptoms: The Super Cruise hands-free driving system may disengage unexpectedly or fail to activate in certain conditions.
- Solution: Software updates are the primary solution. Ensure the vehicle’s cameras and sensors are clean and unobstructed.
- Estimated Cost to Fix: Software updates should be covered under warranty. No cost.
- Recalls: None Found
Exterior
- Misaligned Body Panels
- Description/Symptoms: Some owners have reported slight misalignments in body panels, such as the doors, hood, or tailgate.
- Solution: Adjustment by a body shop technician to ensure proper alignment and fit.
- Estimated Cost to Fix: $100 - $500+ (depending on the extent of the misalignment and labor costs).
- Recalls: None Found
Interior
- Rattling Noises
- Description/Symptoms: Rattling or squeaking noises coming from the dashboard, door panels, or other interior trim pieces.
- Solution: Identification of the source of the noise and application of sound-deadening materials or tightening of loose fasteners.
- Estimated Cost to Fix: $50 - $300+ (depending on the complexity of the repair).
- Recalls: None Found
Summary
The 2024 GMC Sierra EV, as a newly released electric vehicle, is experiencing typical teething problems. The most common issues appear to be related to the electrical systems (infotainment and Super Cruise), battery range estimations, and build quality, such as misaligned panels and interior noises. While some owners have reported more significant suspension failures, it is still too early to tell how widespread this issue may be. Many of these issues are likely to be addressed through software updates or warranty repairs. The overall severity of the issues ranges from minor annoyances to potentially more costly repairs, but the majority are currently covered under warranty. As the vehicle matures and more data becomes available, a clearer picture of long-term reliability will emerge.
