Mercedes-Benz
Gls

i've purchased brand new 2024 gls 450 mercedes benz and this is the 3rd times i have to bring my car to the mercedes facility to add a quarter of oil and jerky shifting so i dont feel safety and comfortable to drive this car anymore. i need help or my money back, what do i need to do?.

On [XXX], my wife and I were driving our 2023 Mercedes-Benz GLS 450 when I pulled over after sensing vibration on the highway. Upon inspection, all four tires were found to be severely worn, with the right rear tire completely bald and showing exposed steel belts. I have attached photos of the tires. The vehicle had been serviced at Mercedes-Benz of Wesley Chapel, FL at 10,000 miles in January 2025, and the dealer noted the rear tires were at 3–4/32" tread depth. Despite this, we were not warned that the tires were unsafe. The dealership did not contact us, did not send photos, and did not recommend immediate replacement — even though they did follow that protocol on our other vehicle (a GLE 350) serviced the same day. This inconsistency in communication led us to unknowingly drive 4,000 miles — including 60 miles at highway speed — on dangerously unsafe tires. The dealership has admitted the tread depth was low at the time of service but is attempting to shift responsibility despite not alerting us to the risk. This is a serious safety oversight. If we had experienced a tire failure at highway speeds, we could have been injured or killed. This type of service-related negligence should be tracked, as it may indicate broader issues in service safety practices at this and other dealerships. The Dealer refuses to take responsibility for their negligence. I have had other issues with the quality of their service, including a recent engine failure on my GLE 350 while crossing a 4 lane highway. Wesley Chapel Mercedes Benz had serviced the GLE 350 two months earlier, including the ignition system. My wife was driving at the time and could have been hit by on-coming traffic. So I have has two dangerous driving incidents because of Mercedes Benz Wesley Chapel Florida’s Service Department.

Over the past 14 months, the emergency breaking system has gone off approximately 25 times during non-emergency situations. Most of the incidents have been when no other vehicles or impediments are anywhere close by. This has created a very significantly unsafe and ongoing situation for my family which so far are being ignored by Mercedes Benz.

car spontaneously caught fire while driving, without any warning, with smoke first coming from the air vents followed by smoke from under the bonnet then visible fire engulfing the front of the car, it was serviced 6 weeks prior without any concerning findings on the mechanical or electrical components. 911 was called and fire was extinguished and insurance claim filed, currently being investigated by insurance as to what may have caused the fire.

Head-up display unit inoperable on multiple occasions over a span of few months during the first year of ownership. Display panel occasionally went blank, including while driving.

The glass panel between the windshield and the sunroof spontaneously shattered. I wasn't aware of this and had just noticed increased wind noise while driving for a few weeks until I noticed that it was due to shattered glass panel. It is cracked almost all around and somewhat dislocated. Upon close inspection in can be seen that cracks run throughout the glass panel. There is no single point of impact of a possible foreign object, so I can rule out the possibility of something hitting it with high confidence. I took it to the dealership but they refused responsibility under manufacturer warranty, claiming it must have been an object hitting it and quoted $3,815.10 for repair. I have detailed pictures showing no impact marks.

The contact owns a 2024 Mercedes-Benz GLS450. The contact stated while the vehicle was idling, the vehicle shut off with several unknown warning lights illuminated. The contact also stated that a message to exit the vehicle was displayed. Due to the failure, the vehicle was towed to the dealer on four separate occasions. The vehicle was towed to the dealer and the contact was informed that the failure was related to the battery. The battery was either recharged or replaced while at the dealer; however, the failure returned soon after repair. The vehicle was not repaired and remained with the dealer. The manufacturer was notified of the failure but offered no assistance. The failure mileage was unknown.

I would like to report that there is a Key Fob connection problem with my car causing it to lock with the key inside the car. This could pose safety issues. I placed my purse with my Key Fob and phone on the passenger seat. I loaded other items in the car. I closed the door to walk around the car to get in the drivers seat. When the door closed, the car immediately locked. My husband had to come with his phone to open with Mercedes Me App. It was a hot day. Fortunately, my infant granddaughter was not in the car. I discussed this event with my local dealer. They informed me that it is happening to other 2024 cars because the fob has a new design which allows it to go into a sleep mode to preserve the battery. They informed that it happens randomly. They were aware of it happening to other customers. I phoned customer service with Mercedes USA. They had previous reports of this happening. They even mentioned that a child had to be rescued by breaking the window. They suggested that I report the problem to your organization. I was told that was the only way that it could be addressed by a recall. Both the dealership and the USA representative said that there was no way to prevent it from happening again. This problem can result in children being locked in the car. This can also result in being locked out of the car in areas with no way to summons help. I am very concerned. There is no warning that could prevent this situation. I will be happy to provide my car for inspection.
