There are 4 owner-reported speed control & cruise complaints for the 2017 Mercedes-Benz GLE-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Car took off after going over railroad track, and accelerated without driver being able to control it. The breaks and steering went out as well. It’s like car was being driven remotely. Crashed into fence, and there was no warning. The car accelerated. The car bounces back and forth when brakes are on, and again last year stopped in the middle of traffic. Water damage was leaking in as well after 8 months having this car. First major incident was December 2024, but rocking and began one month after purchasing vehicle in August of 2024. Acceleration incident; December 2024: 4 months after purchase; vehicle stopping in traffic: April 2025 8 months after purchase. Apparently new tires were put on. Almost had a blow out within 1 year and 4 months of purchase and found out when getting oil changed this past December 2025. Lights and radio randomly shut off, and gas’s tank is often locked or will not close. This car is scary, and has had problems that someone has covered up for a very long time. I have papers claiming everything was checked upon delivery; However; two incidences alone could have ended in multiple fatalities. Someone is responsible for hiding something something here, and this needs to be reported before someone or multiple people die that is due to a defect in the car. MCC 478-877-5740 478-737-2010
On July 3, 2024 I turned right out of a parking lot onto a busy road. The car sped up on its own and started speeding. It took me a couple of seconds to realize what was happening and put on the brake. The car ran through a red light, other cars were able to avoid hitting me. The car did stop then. There were no warning signs that this was going to happen. The dealership is going to investigate tomorrow. The car seems to be running fine since.
CAR NOT STOP .WHEN TURNING TO STOP MY CAR ACCELERATED ON ITS OWN.ON HIGHWAY
THE CRUISE CONTROL LEVER IS THE SAME AS THE TURN SIGNAL LEVER. WHEN SIGNALLING A TURN, IF I PULLED BACK AND UP OR DOWN ON THE LEVER, THE CAR WOULD LURCH AHEAD AT HIGH SPEED. THIS IS DEFINITELY A DANGEROUS CONDITION. THIS IS A DANGEROUS DESIGN DEFECT, AS THE CAR WOULD ACCELERATE QUICKLY. I HAD IT LURCH ON ME SEVERAL TIMES DURING THE 1 WEEK WHEN I RENTED THE CAR. THE FIRST TIME IT HAPPENED, THE CAR SPED AHEAD FOR ABOUT 10 SECONDS AT 65 MPH(I WAS GOING 50 MPH) WHILE I PLAYED WITH THE LEVER TO TRY TO DISABLE THE CRUISE CONTROL
