2 Electrical System problem

Failure Date: 08/18/2023

All of a sudden, the car would not start and inserting the key and turning doesn't do anything. Turns out that like many other folks, the electronic steering lock module is faulty and preventing the car from starting. Found out that only the dealer can fix it and mercedes provides the replacement part. The cost is unaffordable at $2200 from the dealer and the part is back ordered and won't be available for approximately 2 months. This is completely unacceptable and mercedes should prioritize and fix this issue as a safety issue with a recall since it completely makes the car non-driveable and nobody but the dealer can fix this, which allows the dealer to charge any amount they like.

Electronic steering lock (esl) goes out damaged without reason, happened all of a sudden to my parked car. Car simply won't attempt to start and steering his completely locked.

9 Electrical System problem

Failure Date: 01/26/2017

Steering lock issue. Engine does not crank and car does not start. Upon inserting key, an message pops up asking to remove the key. Steering wheel is locked and car stuck in park. Due to the configuration of my parking garage and the fact that the steering wheel was locked, it took me several days and 4 different tow trucks to successfully tow the car 1. 5 miles to my local mb dealership. The diagnosis and repair of the faulty steering lock, which the service advisor says happens all the time with my model, took an entire week. I was told mb does not offer a loaner car in this situation. All in all, it took my 2 weeks to finally get my car working again. The repair was $1,200. Add in the 4 tow trucks, and 2 weeks of rental car and this was easily a $2,000 issue. Mb should issue a recall given that this issue is so prevalent and clearly a fault with the steering lock part.

Esl failure. Apparently this is a very common 1200$ issue with c-class. The key would turn but the car won't start. Had to be towed to the dealer who instantly knew it was the esl. There should be a recall on these issues. So many people are having the exact same problem!.

18 Electrical System problem

Failure Date: 05/12/2015

My vehicle went completely out of service and was unable to start due to a faulty electronic steering lock (esl). My vehicle only has 69,000 miles on it and this seems to be an issue with plenty of other c-class Mercedes Benz owners who have encountered the same issue. Mercedes benz is failing to take responsibility while also my exteneded warranty that I paid $2000 for has also said they will not cover this. I highly recommend not ever buying an extended warranty from privilege protection care. They place generic terms in parts of what they cover and if the dealer or shop has a specific name for your part, although it is the product or part of the same part that needs to be replaced, they will honor the warranty. Also their customer service was rude and not very helpful at all.

20 Electrical System problem

Failure Date: 06/25/2014

I have a 2008 Mercedes Benz C350. The rear passenger taillight malfunctioned causing me to be pulled over by the police. Mercedes benz has since recalled the faulty tail lights and is scheduled to release replacement parts to mb dealers next month. However, it seems the entire electrical system is defective. Sometimes the radio station changes when I adjust the cabin air temperature (air conditioner). The dashboard control panel constantly displays warning messages about failing headlights and side markers. Aside from the recalled passenger taillight which is visibly dimmer than the driver side taillight, the other lights appeared to be working fine. Yesterday the fuel gauge indicator and the coolant indicator on the dash came on - the antifreeze and fuel tanks are both full. I had a mechanic look at the lights, only to discover the plastic housing is completely singed and melted in the headlights and side markers, just like it is in the defective recalled taillight. The car is one over-priced fire trap - at this point I don't feel safe driving it. What is even more disturbing to me, is that Mercedes Benz is well aware of electrical problems with the c class. There are thousands of complaints about this issue online - posted to blogs and NHTSA website. Mercedes is trying to piece-meal out a remedy. Meanwhile, this is a big safety issue! when will NHTSA recall the entire mercedes c class line due to defective electrical issues?.

21 Electrical System problem

My radio plays but smell like something is burning when I turn it on (wires) radio stills plays but screen goes in and out was told I need new radio but was never told that radio may catch on fire .

22 Electrical System problem

Failure Date: 01/27/2014

I went to go turn on my car and it failed. No sound or anything. I called aaa they came and said the battery is good they just don't know whats wrong. I had to get my car tow without knowing what was wrong with it. I took it to the shop and it took them about a week to realize what was wrong with it. I called Mercedes Benz and they had no explanation to what was wrong with it or why it happen. They finally figured it out and they said it was an electric steering lock problem and that its for security reasons and that it can happen anytime. I also had to get a programing key. This cost was very expensive to not have an explanation. I also noted that a lot of c class users had this very same issue and we are not understanding why there isn't a recall.

25 Electrical System problem

Failure Date: 08/03/2013

Warning light came on to check right side tail and brake lamps. Warning sign to also check right turn signal. It appears that these come on after driving about 30s-1min. When opened up the right back light kit, the plastic harness holding the bulbs and wires is burning slightly and slightly charred. Light bulbs are working as they do initially turn on, but then go off after 30s-1min. Also light comes up on check rear left tail and brake lamps. But these work fine, and the left back light kit plastic harness appears normal and fine.

26 Electrical System problem

Failure Date: 08/01/2013

Keep getting the "check right rear tail and brake lamp", "check right rear sidemarker lamp", and "check right rear turn signal". The blinker will work fine, then after 10 minutes of driving it blinks very fast and the warning light comes on. Sometimes none of the lights on the right rear panel will turn on, sometimes they will. Or they will work for 10 minutes and then go out along with the warning signs. I looked at the bulbs today to see if any were burned, and the harness was burned and brown! I have smelled smoke a few times within the last month as well. This issue is getting worse. This is an extreme safety hazard and must be fixed immediately. Please advise!.

27 Electrical System problem

Failure Date: 07/26/2013

Inside dash warning saying "check rear right signal lights" and right signal flashes quicker than normal. Upon inspection, lights were working but bulb holder inside lights and connection harness was melted where the brown wire was. Unable to remove harness out because the connector was melted on. Smelled like fresh burnt plastic. Severe fire hazard!.

28 Electrical System problem

Failure Date: 02/16/2013

Passenger side tail light is considerably dimmer than the driver side. After examining the passenger tail light, I noticed that the connector of the wire harness connected to the housing that is housing all the bulbs is partially melted and it is extremely hot when the lights are on. I also checked the driver's side and it looks like the exact same thing is happening on there, too, but so far to a little lesser extent. Looks a lot like a fire hazard!.

29 Electrical System problem

Failure Date: 07/01/2012

My right tail light had been dim for awhile. I do remember from time to time smelling a faint electrical burn smell but didn't know where is was coming from. Finally when it went out, I pulled the lamp assembly which has what looks like a circuit board where the bulb mounts. The copper "traces" were fried. I took it to the dealership and they said "sorry, it's out of warranty, but we will be happy to sell you one". I said "no thanks, it will just fail the same way". So I took it home and repaired it properly. Now worried the other one will do the same.
