1 Electrical System problem of the 2008 Mercedes Benz CLS550

Failure Date: 09/02/2023

I see there was a recall on instrument clusters on my vehicle in 2001. My instrument cluster is completely black and I can’t see speed or any thing at night. You cant replace the bulb or cluster unless mercedes reprogram it which the price is rediculous. I did some research and seen that mercedes did some recalls for my vehicle but it doesn’t show up. I was told to contact you guys in regards to this.

3 Electrical System problem of the 2006 Mercedes Benz CLS550

Failure Date: 08/09/2021

Re 2006 Mercedes Benz cls500_ 211017_114326 on August 9, 2021, my brakes went out on the freeway when trying to Dodge debris and other vehicles, when the brakes  completely went out and caused me to run over major wood pallet debris, and scared for my. Life to get to the far right lane to make it off te exit with no brakes whatsoever. And causing major under-carriage repairs. Rather than hit the cars on each side of me, all I could do at that point was get over lanes with no brakes, and make it off the exit before I killed myself and/or someone else. The damage  done from the brakes going out, came to over $4000 in damage repairs to the under-carriage and left me without a vehicle for 45 days while in the shop this not only effected my income since  the vehicle was used for lyft,, but I also was evicted from my apt. 30 days later, while my vehicle was in the shop, and unable to work to pay my rent. Once getting the car back these past few weeks, even though repairs were done, the car has continued to threaten my life and others, as the brakes continue to randomly go out at a light, on the freeway, behind a merging car, and ive come so close to having another bad accident. Not to mention since the accident, I am now getting gasoline fumes that seep throughout my car while driving, so profusely, its causing me migraines. But most of all the risk of a fire!.

7 Electrical System problem of the 2011 Mercedes Benz CLS550

Failure Date: 11/17/2014

Today, I was informed buy the Mercedes Benz dealer service specialist at intake, at the only dealer in fayetteville n. C. 3203 bragg blvd. When taking the car in for service that the reverse camera for backing up safely, coaxial cable was damaged causing the camera to malfunction due to opening and closing the truck. Apparently, the truck slices the coaxial cable each time you open and close the truck until the cable breaks, stopping the connection of the camera to the viewer. I don't believing this defect in the use of the truck causing the cable to be cut up should be at the consumers expense to fix each time it happens from simply using our trunks. I also have a disability retirement due to injures to my neck and back working as a law enforcement officer, and that back up camera helps to insure safe back ups for people such as myself.
