My husband drove my car home from work on April 18th 2022 and it was a bad rain storm that everyone. He had to drive through a couple of big rain storms. Soon afterwards he got around the corner from the house and the electric system failed lights started going off everywhere in the car, he lost steering and couldn-??t see and almost crashed and got the car home safely but it wouldn-??t shut off so he had to disconnect the battery for the car to shut off. On April 22 nd the car was towed to the dealership because it wasn-??t driveable and they check out the car and discovered water under the carpeting of the drivers seat near the wiring of the car. I submitted an insurance claim and an adjuster went out to see the damage and his thought is that it-??s due to a known problem for this car that-??s been reported by many people with this same vehicle. The Mercedes Benz c300- 2010-2014 years. I checked online and apparently many people have reported this same issue water underneath the car due to bad firewall manufacturered not sealed correctly which could be a manufacturers/ safety issue. My husband was almost killed thank goodness he made it home safe that night. I believe there are many people that have had this issue and someone needs to be done for safety purposes, and I believe the insurance doesn-??t want to cover the repairs because they are blaming Mercedes-?? Benz. My cars been in the shop a month and I still have no answer from State Farm or the shop Mercedes Benz.

Mercedes Benz C300W light bulbs are constantly blowing out. Primarily due to the heat accumulation in the headlights. The plastic parts are melting, dry and very brittle which causes bulbs to overheat and blow out. Left & right parking lights(4), side lamps(2) and license plate lamp(2) have been changed out at least 15 times per lamp. The dealership suggest I change out the head lamp casing costins approx. $2K with labor. Aftermarket $700 plus labor. The service department at three seperate shops have stated this is a common problem with the mb C300.

Tail light wiring for 2010 Mercedes C300 was replaced under the recall issued in 2014. Tail light wiring is currently experiencing burning/melting due to insufficient ground wire capacity (issue of original recall). Mercedes dealership will not replace the parts under recall procedures and is requiring payment for replacement. Tail lights currently intermittently work but experience total failure of all tail lights (including brake, turn indicator, etc) when not working.

Takata recall I have owned the car for about 1 1/2 years and the recall was from about 2012 I think from looking it up. I have called the hotline many time and got a run around. Was told every time parts would be available within a few months.

My right tail light keeps dimming and going back bright. I thought I needed a bulb but but it gave me a message today for everything on the right side but then the message went away. Last night someone told me the right light was dim then it got brighter. I've been smelling a faint burning smell but today it was kind of loud. I checked and it looks like the plastic and wire is melting on rte right tail light.

Tail light assembly burning up again. My 2010 mb C300 4matic sport had a recall to replace both tail light assemblies about 3 years ago. Now it is happening again and mb dealer wants $159 just for a diagnostic. Problems: Dash warning messages started to appeal saying problems with tail light, brake light, fog light, turn signal, reverse lamp... everything is out. Light bulbs looked fine but I replaced all bulbs anyway (from autozone parts), worked for a few hours, then warning messages showed up again. Replaced all bulbs again. Same thing. Then one day, messages stopped and everything is working again. Then a few days later, it started again. Went to a mb dealer (at chantilly, va) on 10/2/18 who wanted $159 just for a diagnostic test. I instead purchased a new tail light panel (lamp carrier P/N 204-820-15-00-05) at $20 before tax to replace on my own. Came home opened up the panel and found a burned wire. It even melted the black plastic housing of wire hardness and a black burned mark on the panel (carrier). Please see attached photos. This can cause a car fire. Also very unsafe driving because tune and brake lights are not working. Shouldn't mb fix this again at no charge? please recall again.

Took car for routine service at local mb dealership on 9/3/16 and was told both front parking lamps/lights are not working, further informed that it is not simple light bulb blow out but something has caused the whole molding/casing holding the light has melted and the entire assembly will have to be replaced. The service adviser stated that he has seen this type of problem before with this type of vehicle. I am not a technical person and can forward email and the details of issue as provided by dealership. I consider this serious safety and fire hazard and wanted to know if this problem has been reported to you before by consumers or by the manufacturer Mercedes Benz. Mileage on form is approximate

There are two problems that have shown up all at the same time just recently. Over the last several weeks it seems that everyday when I go leave in my car I am getting a new warning message about another light I need to check. At first it was prompting me to check the right rear tail light which appears to be working fine. But now the list has grown to include that tail light, a turn signal light, license plate light and a couple more even though to me it appears that all are working fine with the exception of the license plate light which is truly out. However the warning are listed for all these malfunctioning lights. The second issue is with the power steering. It started making a distressing noise one evening on my drive home, in which I was able to reach my home without trouble. However when I tried to leave the next morning the power steering on the car was completely not working and I was having such a hard time turning the wheel backing out of my drive that I thought it smart not to take it out on the road and pulled it back up into my driveway where it has sat for the last several days. Luckily my son is away at boarding school but he doesn't need his car there so I have had it available to get me to work and back until I had the time to look into the issue with my car which I am doing now.

A little less than a year ago my driver side inner parking light bulb failed, and about a week later the passenger side inner parking light bulb failed as well. When I went to replace them, the bulb and headlight assembly showed visible damage from where it appeared as if both bulbs caught on fire and melted into the headlight assembly, permanently damaging both driver and passenger headlight assemblies. There was the presence of charring on the bulb socket as well. I took the vehicle to the local Mercedes Benz dealership and they stated there was nothing they could do except to replace both headlight assemblies. If it were merely one bulb that failed in this manner, I would have chalked it up to maybe a faulty bulb or socket, but it is very odd that it occurred on both inner parking light assembly. Fortunately
