2022 Mercedes-Benz GLE Reliability Report

Rapid tread wear on the factory run-flat tires is the most costly complaint. Tires get replaced again and again within the first 2 years, with one report counting 12 tires, while dealers find no defect and refuse to help. Other reports describe uneven tread wear and a humming noise after rotation. Several nearly identical filings describe Yokohama tires showing tread separation and dry cracking with under 4000 miles, which the dealer refused to mount. Owners pay for replacements out of pocket.

Every detailed report here is about a fuel system recall, not a failure on the road. Notices arrived for campaigns 23V880000 and 23V445000, but dealers and the manufacturer confirmed that repair parts were not yet available. None of these filings describe a breakdown. The complaint is the wait, which owners say went past a reasonable time. Any car being considered should have both recall repairs completed and on record.

Hesitation and failure to accelerate at highway speed, with the check engine light on, lead to a cracked cylinder head diagnosis in one case, and that car sits at the dealer unrepaired. Overheating at 70 MPH is the other failure. It is traced to the cooling system and fixed with a new cooling fan at about 21,000 miles. Both problems force the driver to pull over on a fast road. One filing gives no details.

Misfires, shaking at idle, and sudden slowdowns while driving point to cylinder head trouble. Owners call it a known issue on the GLE 350 and say the related cylinder head recall leaves this model out. Other reports describe the engine stalling when the transmission fails to downshift fully. There is also unintended acceleration at low speed while turning, right after the brake is released, as if adaptive cruise control were still on. That surge repeats about a dozen times on one car and takes quick braking to stop.

Sudden brake loss is the most alarming report. The pedal turns soft, and within minutes the car will no longer stop. A second report describes the opposite problem. The car brakes itself to a stop at about 25 MPH with no driver input, while warning lights flash and the rear seat belts lock. That event happens at 3,535 miles and is never diagnosed. Both failures carry crash risk in traffic.

An open fuel pump recall is the main concern. Recall letters warn that the pump impeller can deform and stop the pump, cutting drive power and raising crash risk. The remedy is reported as still unavailable locally nearly five months after the notice, leaving the owner unwilling to drive far from home. The other filing blames the injectors and fuel pump without describing an actual failure. The recall repair should be confirmed before purchase.

Two opposite acceleration faults appear. In one, the car will not go faster than 20 to 25 mph even with the pedal floored. The dealer blames software, then hardware, which leaves doubt that the repair worked. The other, filed about a 2020 model, describes the car surging during a slow turn into a parking space. The brakes seem not to respond until Park is selected. Both create loss-of-control risk at low speed and in traffic.
