2023 MERCEDES-BENZ Glc 300

I have taken the delivery of this car on May 2023 and has been having many issues including but not limited to rear seatbelt malfunction that needed replacement. Recent major issue is constant 'check engine light on' for various issues. Below is the 'F' and 'I' items from 'initial quick test log' as of [XXX] and also attaching detail log file. No resolution or action has been taken after several trips to the dealership in past couple of weeks and not being able to drive due to safety concern.

I am having the following issues with my digital lights on my 2023 GLC. Dealer states normal. It is unsafe and should have a recall/software update. VIN: [XXX] Dangerously inadequate forward visibility at night on low beam/inadequate beam pattern. Level of illumination not at legal minimum of visibility on low beam/ no long distance illumination yet creates excessive illumination of retroreflective signs creating distraction. Adaptive Driving Beam not functional. Extremely limited beam pattern on low beam. Topographic/dynamic leveling does not adjust beam so you are blind going down hill/up hill at night. Poor image/contrast for projection/symbols. Only triangle works. Cornering light not functional. Cannot see sides when cornering at night. Mercedes complaint reference # [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

DIGITAL LIGHT low beam inadequate distance for safe driving on unlit roadway. Low beam has unnecessary blacked out areas causing distraction. Low beams too low, especially driving down hills. Adaptive high beams revert to low beam without any apparent light to trigger camera/sensor. Dealer states they are all the same, nothing they can do, call MB USA. MB USA gave me a case number but do no seem interested in solving the issue

The digital lights are defective for the US market. The low beam doesn’t provide any light for night driving farther than x feet. It also has jagged edges across the beam that greatly effect night visibility. The adaptive part of the system doesn’t provide adequate lighting in the dark around curves, the car states it has cornering lamps but it does not/ is not activated for us market. When it’s completely dark, I cannot see the front sides for turning, the lights are a serious safety hazard. The headlamps also get condensation when wet and fog up and effect visibility where you cannot drive at night. The leveling sensor failed and subsequently rendered the auto high beam and adaptive lighting system inoperative. The car doesn’t do any of the listed safety projections it’s supposed o do, such as spotlight. One time it worked but when tested it was never able to see it again after a software update. Serious safety concerns regarding the over the air updates and advertised functionality vs real life performance

The moon roof will not close. There is also a sloshing sound of water in an unidentified area, it has not rained. The blind spot monitor function of the digital light projection works intermittently and is barely visible marking on the roadway. The exit assist also does not activate the ambient lighting when opening door and car Is approaching in the travel Lane. Digital lights have jagged output light beam and they are the illuminating the roadway as advertised.

Sunday, June 25, when I was driving the car on the road, the engine shut off and the car stopped running. 3 warning lights show on screen: engine light; 48v Battery Service Required; 12v Battery service required. I used the break to park the car on the roadside after that. I tried many times to restart the car, Waited over one hour and 40 minutes it finally started again, the engine warning light was still on until the second day morning, and I was able to take pics as evident. 1. What component or system failed or malfunctioned, and is it available for inspection upon request? Yes, but on the second day, the MB service dep told me that the car was having a system update (while I was driving the car and it turned off the engine by doing that) 2. How was your safety or the safety of others put at risk? I was still driving with 40m/h+ on the road, my car suddenly having a malfunction. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? No, I called MB USA, they started a purchase buyback application, but still let me drive that car. 4. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No. The 3 warning lamps showed when the engine shut off while I was driving. There was no other symptoms of the problem prior to the failure. The car is new, 2023 GLC 300, the dealership is AutoNation, only has 2400 miles on it do far, one month only so far.
