2019 Mercedes-Benz GLS-Class Complaint Log

When I attempt to shift from park to to drive or reverse or even neutral the car wont respond. this has happened a couple of times in the last two months. I press on the brake in order to shift and it wont respond to any commands . I then have no choice but to turn off the car and then turn it back on. that usually works. this is unsafe if i was at an open parking lot or even on the street doing a U-turn and I don't turn right then having to reverse and the car doesn't respond. very scary stuff.

See attached document for complaint.

Yes, Euro Motorcars Devon Mercedes-Benz. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, a diagnostic was done highlighting the problem. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, Active Curve System Malfunction. Oil in the Active Curve System is leaking. This leaking oil, in the presence of an ignition source, increases the risk of a fire.

NHTSA Campaign Number: 18V272000 Manufacturer: Mercedes-Benz USA, LLC. Components: SUSPENSION

While driving my car the check engine light comes on. The code is P06DA (OIL PUMP SOLENOID OPEN CIRCUIT - ELECTRICAL ISSUE). Dealer states repair is $5000!!! Car is not able to pass inspection due to the check engine light.

The panoramic sunroof spontaneously shattered while driving down the road. The glass blew out from the inside out. There didn't appear to be any issues with the sunroof before this. As far as safety, just the noise of the explosion was enough to surprise the driver causing a jerking of the steering wheel into the opposite lane of traffic which could have caused a head on collision. If the sunroof shade would have been open, the glass would have came down the drivers and passengers as they were going down the road. Saying this was distracting is an understatement. I called the local Mercedes dealership and was completely dismissed by them. They said it would have to be repaired by a glass company which is incorrect. The glass was replaced by the local collision center.

The manufacturer was notified of the failure. The failure mileage was 38,000.

9/9/24 after 5pm I'm driving my car and the check engine light came one. I have a small autel handy scanner always in my car. I checked it right away and gives me the code P06DA (OIL PUM SOLENOID OPEN CIRCUIT - ELECTRICAL ISSUE). I stop on the side for a quick check, no knocking noise from the engine and runs good. I checked on the website (Mercedes forums) and a lot of people had the same problem (lemon???). Most of them talking that thanks God the solenoid stuck on full open (higher pressure oil) so there's no damage to the engine. Repair cost around $5000!!!!! That problem must be taken seriously from Mercedes! Thank you

Vehicle triggered into limp mode while driving, Braking Assist Disabled, Traction Control Disable, Sound System Disabled. Sent to dealership for repairs. Dealer found water pooled in the passenger side footwell. Estimation 10-20k to fix vehicle. Matching the exact details of the recall issued against 2020-2021 Mercredes Benze GLS450. Water forms as a typical byproduct of a car’s air conditioning system and is diverted away from the car down to the ground through a drain hose. In the affected vehicles, the drain hose may be incorrectly installed, causing water to leak inside the cabin through the front passenger footwell. The component involved in this recall is the A/C drain hose with part number A1678323600. Recall risks Water entering the passenger compartment presents many risks to both the vehicle and the occupants. Rust could form from within the vehicle and the water can also potentially short out the electrical system. Apart from presenting an increased risk of fire, this can also cause the car’s electronic features to malfunction, which could affect the ability to unlock doors and call emergency services. The leak can also accidentally trigger the engine’s limp-home feature while driving, upping the probability of a crash. Warning signs Users may notice that the front footwell carpets have become wet under normal use, as well as misting on the windows.

I have been showing an error "Active Curve System Malfunction" intermittently since I bought this vehicle from Mercedes dealership, and I've started seeing oil leak from reservoir. I've seen this is a recall from 2013 to 2017 model, but I'm unable to see this as a recall on 2019 model.

Failure of driver side front axle CV assembly. Part #166-330-33-00 with 36,000 miles on the vehicle Noise was heard when driving, pulled over heard noise as moved car forward and made left turn. Car was towed to Highway Tire and Auto near our house on a Saturday morning. Car test driven on their lot and immediately identified as CV axle. Part was only available from Mercedes dealership, yet all the other axles ( non driver side) were available from several parts distributors. Seemed odd maybe indicating a lot of these were being replaced?? This axle failure while driving at highway speeds could have resulted in wheel lock up causing serious accident and injury. When contacting Mercedes they seemed more interested in telling me it wasn’t covered under warranty, and there was nothing they could do about it since I didn’t have the repair done at their shops…. I asked them if they thought it was normal for an axle to go out at 36,000 miles and they said no. I asked them if they thought it was concerning and potential safety issue. And they never gave me an answer. After about 20 phone calls and 4 emails was finally able to escalate it to Mercedes Corporate office and a lady there Andrea, indicated she was executive referral manager and she would check with their engineers. She called back next day and said since I didn’t get it repaired at Mercedes, and since last time it was in a Mercedes shop was 15 months earlier there was nothing they could do about it. She said they might have found leaking fluid etc and could have fixed it. I told her I personally saw it up on the lift and there was zero leaking fluid or indications of wear on the outside. The car had also just recently gotten new tires and passed state of NC vehicle inspection. She said she was sorry but best she could do was offer $400 credit toward a future service at any Mercedes dealership. I think this has potential for serious parts defect and consideration for safety recall

At first, the parking brake assist would appear when vehicle was put into park or when starting. We would have to release the parking brake each time. Then, the parking brake assist light would not go on, but the parking brake assist would engage and or be sticking while driving causing a burning smell and damage to the rear braking system including brake pads and calipers. The independent repair professional described this as being a very premature issue for this vehicle considering the age and mileage. The electronic parking brake actuators electric motors malfunctioned and failed causing resistance on the calipers. The car was undrivable and required us to obtain a rental car for several days.

Vehicle was damaged by a school bus hitting the rear passenger corner. It damaged the rear tail light, brake light, turn signal and backup warning sensors. Parts to repair the vehicle are not available for the past 4 months. I called multiple times and the dealer cannot provide a date when the parts will be available. The total cost of repairs is $3200.00. To avoid paying rental car fees that the school would have to pay, I’m driving a unrepaired car. The cost to rent a car would exceed the cost to repair the vehicle by 3-4 times the total repair cost. It is a law that car manufacturers have parts available to repair vehicles damaged by accidents. I would like NHTSA enforce the law.

factory equiped jack lift failed, bearing and ring ejected and vehicle fall on the ground, contacted manufactory, and Mercedes indicated they probably can replace a new jack but no more action they will take, the vehicle has a gross weight about 6400lbs, and with air suspension, the vehicle will need to be lift higher than normal in order to replace tire, the jack lift is obviously not hold the pressue that make it a serious safety concern, Mercedes should look into it not just drop the ball.

Update Communication Module SIM Card Software - MBUSA ID: [XXX], NHTSA Recall ID: 22V365. I received the recall letter from MBUSA in July 2022. I took my car to a local dealership on 8 Aug 22 and they told me after approximately two hours they couldn't update/do OTA. They told me I would need to park my car outside to receive the update. Once I got home I checked the MBUSA & NHTSA recall sites and noticed this recall for my vehicle shows it as updated, but I knew the dealer hadn't accomplished it, because they said they didn't. I'm not sure who submitted it as updated on both websites. We have the MercedesMe Connect applications on our iPhones and it shows the status of our vehicle, allows remote starting, has anti-theft tracking as well as valet tracking and remote disabling capabilities. It also show the Over-the-Air (OTA) updates. It shows our vehicles LAST OTA as being 14 Oct 2021. I believe this software application shows current status of the OTA software and that this recall update on your website and MBUSA is incorrect. How do I go about getting this recall resolved. I can send you a screenshot of our MercedesMe Connect showing the current status of our vehicles OTA software. I've attached the screenshots of my MercedesMe Connect's OTA information. Hopefully nothing happens accident wise and the OTA not work...this would be a major liability for both MBUSA and NHTSA having faulty information in your database concerning this recall as being updated/corrected. If I don't hear from you all, I'll take this matter up with my auto insurer USAA. Thank you! Sincerely, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

MERCEDES BENZ HAS GROSSLY MIS-REPRESENTED THE ACTIVE BRAKE SYSTEM FEATURE. THE OWNERS MANUAL LEAVES OUT A KEY ELEMENT, WHICH IS THAT THE DRIVERS FOOT NEEDS TO BE OFF THE PEDAL FOR THE FEATURE TO ACTIVATE. I.E. THE FEATURE WILL ONLY WORK WHEN THE DRIVER IS NOT PRESSING THE ACCELERATOR. THIS IS A CRITICAL FEATURE AND ONE THEY SHOULDN'T OMIT. I EXPECT THE THE AUTO BRAKE TO COME INTO EFFECT WHEN I'M APPROACHING A CAR IN FRONT OF ME AT A A PACE THAT WILL LEAD TO A COLLISION. BUT IT DOESN'T WORK THAT WAY. FOLLOWING IS WHAT THE OWNERS MANUAL SAYS (NOTE THAT IT DOESN'T SAY ANYTHING ABOUT THE FOOT OFF THE ACCELERATION). "ACTIVE BRAKE ASSIST CAN HELP YOU TO MINIMIZE THE RISK OF A COLLISION WITH THE VEHICLE TRAVELING IN FRONT OR REDUCE THE EFFECTS OF SUCH A COLLISION. IF ACTIVE BRAKE ASSIST DETECTS THAT THERE IS A RISK OF COLLISION, YOU WILL BE WARNED VISUALLY AND ACOUSTICALLY. IF YOU DO NOT REACT TO THE VISUAL AND AUDIBLE COLLISION WARNING, AUTONOMOUS BRAKING CAN BE INITIATED IN CRITICAL SITUATIONS. IF YOU APPLY THE BRAKE YOURSELF IN A CRITICAL SITUATION, ADAPTIVE BRAKE ASSIST SUPPORTS YOU WITH SITUATION DEPENDENT BRAKING ASSISTANCE"

BACKUP SAFETY ALERT SYSTEM DESIGN IS INADEQUATE. EXTERIOR SENSORS ARE INSENSITIVE OR ERRATIC, WARNING BUZZER IS FAINT-TO-INAUDIBLE, ESPECIALLY IF THERE IS OTHER AMBIENT NOISE SUCH AS RADIO PLAYING, AND WARNING BUZZER SOUND LEVEL IS NOT ADJUSTABLE. WARNING LIGHTS THAT ARE COUPLED TO THE AUDIBLE ALERT ARE REMOTE FROM THE DRIVER, NOT VISIBLE WITHOUT TURNING DRIVER'S BODY AROUND 180 DEGREES, WHICH IS NOT POSSIBLE FOR MANY DRIVERS. SYSTEM SHOULD BE DESIGNED SO THAT WHEN THE CAR IS IN REVERSE GEAR AND IN MOTION ANY ENCROACHING PEDESTRIANS OR TRAFFIC OR OBSTACLES RESULT IN AN AUDIBLE WARNING COUPLED WITH WARNING LIGHTS THAT ARE VISIBLE IN THE DRIVER'S FIELD OF VIEW, WHICH WAS APPARENTLY THE INTENT OF THE DESIGNER. HOWEVER, THIS DESIGN AND ENGINEERING FALLS SHORT OF BEING EFFECTIVE, AS THE SENSORS AREN'T RELIABLE, THE BUZZER IS NOT LOUD ENOUGH, AND THE LIGHTS ARE NOT VISIBLE TO PEOPLE UNABLE TO TWIST THEIR BODIES AROUND TO LOOK DIRECTLY BACKWARD.
