ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL
The instrument cluster gauges start giving in accurate information and the whole dash start turning on and off. I found hundreds of people posting complaints about this issue with the 2018 mercedes cla 250 but mercedes refuses to acknowledge this issue and put out a recall probably out of greed and to not loose money. This is a dangerous issue. Mercedes wants to charge people appropriately $3,000 for parts and labor to fix this issue which is ridiculous. Please look into this. There needs to be a recall. This is dangerous especially for the people that cant afford this repair.

ELECTRICAL SYSTEM
I have sent the below email over 100 times to Mercedes To whom it may concern, I am writing regarding the purchase of a CLA250 4matic in December. I had a 120 point inspection done that did not show any issues with this car. As I was driving down a dark road around 1 am, my life was thrown in danger as the command shaft shut off and I could not see the dashboard or any lights in the vehicle. I was alone and on a dark road. After sitting for 15 minutes, I was able to get a light to come on and drove to my destination. On my way home, the lights were acting erratic and the brake lights, bright lights, engine lights, gas gauge, rpm gauge and caution lights were flickering the entire time. The car had no problems starting, however this continued to happen. I parked the car for several days and after starting it again, the dashboard was black, I could not see to put it in park. I tried several days later and got the lights to come on and after driving through the light, the parking brake was thrown in place as I was driving, almost ejecting me from this vehicle. I immediately turned around and parked the car for over a week until bringing it to your service location at Atlanta South. The car put my life in danger, almost ejecting me out of the car. Thankfully I was not on the highway driving higher speeds or I would have been killed.. I am asking for Mercedes Benz to cover the entire amount for the command which I was told during service check was defective and wiring issues within the command. The cost is over $2,900. I believe this is a manufacturing defect whether you have any recalls on it or not. I will file a safety recall complaint with the NHTSA Nation vehicle recall for these vehicles of this make and model advising that you could be killed while driving this car without further recall. I have had other Mercedes benz vehicles and never had this problem. This is a matter of life or death. The car is currently parked at the dealer after inspection.

AIR BAGS
My clock spring is no longer working, it made all the buttons on my steering wheel stop working and i am afraid the airbag will deploy at random since there was a recall on cla models 2015-2018. I own a Mercedes cla 250 2018 but it is not showing a recall on my specific vehicle. Not only that but they no longer sell just the clock spring for my car, im assuming because of the recall. I am scared that my airbag will randomly deploy while im driving or that it will not deploy at all in case of an accident. It was diagnosed by an independent mechanic There was no other messages except when my left side airbag service needed message popped up

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, ENGINE
I am driving around 55K miles in this car, and my check engine light comes up. I head to a local place to get a code check. The guy looks it up and tells me this is pretty much with EVERY Mercedes CLA around that mile point.. So, I look up on reddit and other forums, and it's exactly what he said. Pretty much the PCV valve is faulty and costs around $1800-2500 to fix after 50-60K miles which causes emission problems and other safety concerns if not taken care of. It makes no sense how this is not a recall. Of what I read, Mercedes knows all about this and has done nothing, just leaving the drivers to take care of a problem that they did nothing to cause. I am not sure if this is for the NHTSA or what, but it is kind of unacceptable.
