2021 MERCEDES-BENZ AMG GLE53 Complaints

An authorized dealer returned a vehicle with loose hardware in a moving mechanical track, posing a risk of mechanical failure or distraction while driving.

According to the dealer, there are fault codes in the system for Transmission control unit failing. Thats what caused the vehicle to go into "limp" mode... That needs to be replaced. In an instant, the warning lights and reduction in power occurred simultaneously. The car slowed down and had to coast to shoulder of the highway crossing multiple lanes of traffic. The warnings that came on said “car cannot shift”, “battery failure warning” and when stopped; “do not restart the car.” The shoulder was very narrow and we could have easily been hit by the cars passing at high speeds on the beltway. We had to wait 2 hours for Mercedes roadside assistance to arrive. The dealer is saying it will be $6,000 to repair this.

Engine harness wires insulation is falling apart very early after 3 years. It’s causing arching inside the insulation. Issues is from overheating and can cause a fire. Isolation needs to be upgraded and wire harness needs replaced.

Vehicle unexpectedly lost power on a major highway. Limped into a service station, called for a tow truck. Several days later vehicle was repaired with a bill of $2800. Four weeks later, while driving, check engine light comes on. Contact dealership that completed repairs, brought car in. Now it’s the 48V Hybrid battery needs to be replaced, $4000. Based on some cursory research, this is a known problem in these cars. Mercedes Benz needs to be held accountable. The car was purchased brand new three years ago.

Purchased as a CPO directly from a local dealership. Vehicle has experienced multiple (10+), seemingly random failures of the Electronic Stability Control, Blind Spot Assist, Lane Keeping Assist and Active Break Assist under varied driving and weather conditions. On two separate occasions (one at 15+ mph and the other at 65+), these system failures were accompanied by a brief "limp mode" and immediate total loss of acceleration. The most recent loss-of-acceleration event occurred during lunch hour traffic on the highway, at highway speeds. The vehicle has been taken to the dealership to address these issues on 3 separate occasions. Visit #1: the communication fault codes were noted by the technicians, but they could not replicate the issues. The faults were cleared and the vehicle service was deemed complete. Visit #2 (3 days later and the first instance of acceleration loss): report from service department reads almost identical to that of Visit #1 except the notation that "...found several stored faults for communication with engine control unit." Again, the issues could not be replicated and the faults were cleared. Viewed as an unacceptable response by the consumer, the dealership retained the vehicle for further troubleshooting with the follow-on report noting, "Found no socket tension at Sockets 27 and 28 to PTCU. Removed and replaced sockets 27 and 28 at ME connector 6." The faults were, again, cleared and the vehicle was returned to the owner. Visit #3 (roughly 5 weeks after last visit and the second instance of acceleration loss, this time on the highway): The same complement of warning lamps illuminated, the car lurched, and there was zero acceleration. The vehicle was navigated to the highway's shoulder without incident and shut down. After 5+ minutes, the vehicle was restarted and acceleration functioning had returned. It was immediately driven to the dealership where it currently awaits repair.

We bought this GLE AMG 63 new, it has only 1100 miles and we have had two 48 V batters replaced; they just towed it again to the dealer 22 March because it needs yet another 48V battery; the techs say it’s a design problem but there is nothing they can do except get “approval” to have the 48V battery replaced. It has also shut down while driving causing us to pull over on freeway; We don’t five it (1100 miles) because we are concerned about safety issues from the 48V battery failing at unexpected times; firs, overheating and battery coolant issues…etc. We believe this falls under the Lemon law and should be recalled. Thank you for your time and I look forward to your feedback.

When vehicle is driven 70 mph and above the drive side of vehicle is making a whilst noise by ear of the driver, that is coming into the car. The gas cap door is not sitting flush with the body of the vehicle.

The contact owns a 2021 Mercedes-Benz GLE53 equipped with Continental Tires, Tire Line: Sport Contact, Tire Size: 255/40/ZR21, DOT: (Unavailable). The contact stated that on several occasions while driving 30 MPH on wet pavement at low speeds, the vehicle started to shake, and a loud abnormal sound was heard in all four tires. No warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed that the tire assembly needed to be replaced; however, there was no repair for the failure. The manufacturer was notified of the failure and the contact was advised to call the NHTSA Hotline. The failure mileage was approximately 18,000.

2021 MB GLE 53 AMG Coupe. Less than 7500 miles. Car wont start throws a red error saying see the operators manual. This is the second time in 5 months this has happened and is extremely frustrating given MB is fully aware of the issue. They say it is related to software but I just had my car at the dealer for another issue and all software was updated. This is a design flaw that MB needs to fix before someone dies. The issue can happen at any time, I have just been lucky enough that both times it was parked in my garage. I am now considering pursuing a full refund under lemon law, I no longer feel safe driving this car and each time it has been in the dealer for repair I am without a vehicle for 2 weeks. Very disappointing for a vehicle that cost almost 100k.

In the middle of driving it down the road when - without warning -- the instrument panel went black, the entire panel. My husband was on his way to the dealership to replace a tire when this happened. Though he was able to make his way to the dealer, we consider this event to be a serious safety issue, given that there was a partial power outage involving the components the driver relies upon to drive the car - for example, the driver's side instrument panel has indicator lights for the odometer, gas & oil levels and especially, the gear shift controls. My husband asked the dealer to look into the problem and was told a 10682 Electrical test was performed showing that the Head Unit had a fault. When tested again it showed no fault & no available software updates, so they cleared the Head codes and ran the test, which came up negative.
