ELECTRICAL SYSTEM, SEATS, UNKNOWN OR OTHER
My 2016 CLA 250 having multiple electrical and driving issues that are not recalled. I’ve researched online and found most of these issues are common. 1. Dashboard screen and radio console lights turn off completely. USB connection triggers electrical symptoms. Front and Back seat window control (driver) triggers electrical symptoms and sometimes corrects the problems. Trunk opens by itself while parked and/or stopped at red lights. The instrument cluster has times multiple warning lights turn on and stay on. At times the fuel needle drops completely down as if I have no fuel in the car. The instrument cluster lights stay on after I have turned the car off and locked it as if the system is confused. I have more issues but those are a few to name. I also have video and pictures to prove these things happen randomly then the vehicle can go back to operating normally. I’ve taken it to service and all they have done is reset the warnings.

POWER TRAIN
In November 2024, while at a stop, the car shut off. A few weeks later, while driving the car over speed tables/humps, the car shifted from drive into neutral. No warning or error lights appeared on the dashboard. It just showed that the car was now in neutral. I was able to shift back into drive and continue. Fortunately, I was in a residential neighborhood, going about 10 miles per hour and had only one car behind me. This happened again in December, with the same scenario and on the same road, so I took the car to the dealer. They did a diagnostic and was not able to duplicate the problem, but said there were some error codes and it could possibly be the starter, auxiliary battery or transmisson service, since I had not done one. They also stated there was a Coolant Thermostat electrical fault code. They scheduled me to come back in January 2025 since I needed a loaner car. They kept my car for a couple of days to do a more detailed diagnostic. In the end they replaced the auxiliary battery and did a transmission service because they could not replicate the problem. Said that there was nothing in the transmission fluid of concern and, the starter code had not returned. Stated that it could have been an electrical fluke. No other codes were showing. They did say that some time in the future I would need a coolant thermostat. Car ran well for a few weeks and then in February 2025, going over the same road with speed humps, the car went into neutral. The car has been in the shop for the last 7 days and they are trying to figure out what is happening. I am submitting this because I found many other people posting on forums about having the same issue. My concern is what will happen if my car moves into neutral while I am going at a high speed. It puts me, my family and others lives in danger if my car stops suddenly.

UNKNOWN OR OTHER, ENGINE, ELECTRICAL SYSTEM
Check engine light with error code P052E. From my research, this is a very common issue with this engine and one that either has been recalled or is planning to be recalled. According to some online forums for Mercedes Benz, Mercedes is being sued over this problem and has issued an extended warranty on certain models because of how common this problem has become. The list of models needs to be expanded to include other models experiencing the same problem.

Within 2 weeks after purchasing this vehicle the front stationary roof panel flew off the car. I noticed it when I parked at work in the parking lot. I do not know where the panel is. I retraced my route and did not see it anywhere. I work less than 2 miles from work with no turns. I am very concerned that the panel may cause water damage/leaking and even be a danger / damage to another drivers safety. I went to MB they said that there was no recall. They said that I should file claim to repair it. Claim and repair done be MB. NOW the same thing happened again. The panel has flown off again while I was driving on the highway around 3:00pm the panel nowhere to be found. MB said file a claim. 2 repair companies said the glue /sealant could be the issue. There were no notifications that this would happen. Pictures have been taken for both incidents. Upon referencing Vehicle Compliance & Analysis there is a recall Campaign Description: 23P2197658 NHTSA ID 23V854 I am having a difficult time getting my vehicle repaired without having to file another claim or paying for it myself.

UNKNOWN OR OTHER, STRUCTURE:BODY
I was driving down [XXX] and heard what sounded like an explosion/loud bang sound and shattered glass. I was unsure what happened and where the sound was coming since I was driving alone on the highway and was panicked. I knew glass had broken because I heard the glass shatter and felt the air from the outside coming into the car. I found a safe place to pull over on the shoulder of the highway and found that the sunroof had shattered and there was a large hole in my sunroof. Had my shade screen not been closed on the sunroof, the glass would have fallen on me and into the vehicle. The shattered sunroof not only terrified me while driving but caused me to be so distracted that I almost caused an accident injuring myself and/or others. After calling the police, they came to clean the large pieces of glass off of the top and provided a report number and told me I could finish my drive home with my husband following behind me. I called Mercedes customer care and reported the issue and was informed to have the road side service pick the car up to be inspected at the dealership. I have owned the car for 1 month and a half.
