2020 Mercedes-Benz GLE Reliability Score & Common Problems

Owners of the 2020 Mercedes-Benz GLE frequently report issues with the power train, particularly involving transmission failures. Common symptoms include sudden loss of vehicle movement, stalling at various speeds, and jolting or thumping noises when shifting gears. These problems often appear at low mileages, with some reports indicating failures as early as 100 miles. Safety implications are significant, as some owners experience vehicle shutdowns while driving, which could pose a risk in traffic. Buyers should be aware of potential costs and downtime associated with transmission repairs or replacements.

Owners report issues with the airbag system in the 2020 Mercedes-Benz GLE, primarily involving the airbag warning light and malfunctioning passenger seat weight sensors. Complaints frequently mention the passenger airbag being disabled due to a failed weight sensor, with no estimated time for repair, affecting the seat belt reminder function as well. One complaint involves a crash where airbags did not deploy, resulting in two injuries, and mentions a failure of the Active Brake Assist system. These issues are noted in vehicles with mileage around 30,000 miles, and the lack of airbag deployment in a significant collision highlights potential safety implications for prospective buyers.

Owners of the 2020 Mercedes-Benz GLE frequently report issues with the suspension, particularly with the rear shock absorbers failing around 30,000 to 33,000 miles. Symptoms often include unusual noises such as rattling and sounds when driving over bumps. Some complaints mention that these issues are associated with a recall campaign that does not cover all affected vehicles. Additionally, owners describe instability when driving, particularly in curves, with reports of the vehicle swaying or losing control, which may increase the risk of accidents. These issues are particularly concerning for buyers considering the vehicle's handling and safety.

Owners of the 2020 Mercedes-Benz GLE report issues with the service brakes, particularly when using driver assist features. Complaints frequently mention unexpected and abrupt braking without reason while driving, which can pose a collision risk. Some owners describe complete brake failure, with one incident resulting in a crash at highway speeds. Symptoms include brakes becoming soft or spongy, ultimately leading to a lack of stopping power. Additionally, there are mentions of unrelated warnings about camera malfunctions and false alerts of nearby vehicles. These issues have persisted for some owners over extended periods, despite repeated service visits, indicating potential ongoing reliability concerns.

Owners of the 2020 Mercedes-Benz GLE report issues with the fuel system, primarily involving the fuel pump and fuel delivery module. Common symptoms include the illumination of the check engine light, and in some cases, the battery warning light, accompanied by messages advising against driving the vehicle. These problems typically arise around 29,000 to 79,000 miles. While no crashes or fires are reported, these issues can lead to the vehicle being inoperable, requiring towing and repair. Buyers considering this model should be aware of these potential fuel system failures and verify if any recalls apply to their specific vehicle.

Owners report issues with the rear seat belts of the 2020 Mercedes-Benz GLE, specifically noting that the belts can become faulty and cease to move past a certain point. Complaints frequently mention difficulties with the rear middle and rear right side seat belts, requiring repairs that may be costly. One owner highlights a delay in part availability for repairs, indicating potential wait times for resolution. No specific mileage range is provided, but the issues appear in newer vehicles, suggesting problems may arise relatively early in the vehicle's lifespan. While no crashes or direct safety incidents are mentioned, the inability of seat belts to function properly could pose a safety risk.

Owners of the 2020 Mercedes-Benz GLE report issues with the forward collision avoidance system, particularly related to its failure to activate in critical situations. Complaints frequently mention that the system does not provide warnings or automatic braking when approaching obstacles or other vehicles, even when the red triangle warning light activates. These issues are reported to occur during normal driving conditions, such as clear days on freeways or at night on surface streets, with some incidents happening at speeds around 30 mph. No specific mileage range is indicated, but the problems are described in new vehicles. The potential safety implications include increased risk of collision if the system does not engage as expected, which is a concern for prospective buyers.
