2021 Chevrolet Traverse Reliability Score & Common Problems

Owners report frequent issues with the brakes on the 2021 Chevrolet Traverse, primarily involving squeaking and grinding noises. These symptoms are noted even at low mileages, with some complaints occurring as early as 1,247 miles and others around 15,000 miles. Several owners mention that dealers attribute the noise to the newness of the brake components, suggesting it may resolve with use, though some owners express dissatisfaction with this response. Additionally, there is a report of brake fluid leakage leading to an empty reservoir, which required immediate towing and poses a potential safety risk. No crashes or loss of control are reported, but the presence of fluid leaks and erratic braking behavior could be of concern to potential buyers.

Owners of the 2021 Chevrolet Traverse report issues primarily related to exhaust components, with multiple complaints about broken catalytic converters and exhaust pipes. Typical symptoms include loud noises, abnormal clicking sounds, and noticeable fuel or exhaust odors. One owner describes a brief loss of power while using cruise control, accompanied by a burning smell, though no crashes or fires are reported. These issues appear to occur at varying mileages, with one specific mention at 36,000 miles. Buyers should be aware of these potential exhaust-related problems when considering a used 2021 Chevrolet Traverse.

Owners report issues with the steering system of the 2021 Chevrolet Traverse, primarily involving steering assist reduction and related electronic stability control (ESC) malfunctions. Typical symptoms include warning messages such as “Service ESC” and “Service Power Steering, Drive with Care,” and difficulties in steering, especially at higher speeds, which may pose safety risks. Some complaints indicate the need for a steering rack replacement or a software update to address these issues. Additionally, one report links steering problems to a failing alternator, which affected battery charging and engine power, nearly leading to a highway collision. These complaints do not specify mileage, suggesting the issues may not be tied to vehicle age or usage.

Owners report issues with the airbag system in the 2021 Chevrolet Traverse, particularly in crash situations. Complaints frequently mention non-deployment of airbags during collisions, with one owner describing a steering wheel airbag that failed to inflate and another noting a complete lack of airbag deployment despite significant front-end impact. Both incidents involve crashes with injuries, highlighting potential safety implications. No specific mileage or timeline patterns emerge from the limited data, but the described failure to deploy airbags during collisions is a critical concern for potential buyers assessing vehicle safety features.

Owners of the 2021 Chevrolet Traverse report issues related to the fuel and propulsion system, primarily involving the exhaust and purge valve components. One complaint describes an exhaust leak due to a hole at the bracket location of the driver-side exhaust flex pipe, accompanied by rattling and increased exhaust noise, with repairs costing around $600. Another owner notes a persistent ticking noise from the purge valve, which the dealership states is functioning as designed, although the noise was not present when the vehicle was purchased three months prior. There are no reports of safety implications such as crashes or fires associated with these issues. These complaints suggest potential repair considerations for prospective buyers, especially regarding exhaust system integrity and purge valve noise.

Owners report issues with the seat belts in the 2021 Chevrolet Traverse, specifically involving the front passenger and middle seat belts. Complaints frequently mention that the front passenger seat belt does not latch properly and sometimes releases on its own. Additionally, the middle seat belt fails to retract. These issues are described without reference to specific mileage or timeframes and do not mention any associated accidents or injuries. Prospective buyers should be aware of these seat belt function concerns, as they may affect passenger safety.

Owners of the 2021 Chevrolet Traverse report issues with vehicle speed control, particularly involving sudden acceleration and difficulty in controlling speed. Complaints frequently mention symptoms such as the vehicle shuttering during takeoff, causing jerking motions that can lead to neck injuries and near accidents. One incident involved the vehicle failing to stop despite brake engagement, resulting in a crash and two injuries, with no prior warning indicators. These issues suggest significant safety implications, including potential loss of control and increased risk of collisions. Buyers should be aware of these reported problems, especially when considering a used model.
