My Mercedes started smoking from within the cabin. I traced it down to the speaker in the car. I contacted the Mercedes dealership and told them that my speaker was burning and smoking. The service advisor knew exactly the problem and said that the factory amplifier went bad and is causing an electrical issue in the car. He had seen this before. However, Mercedes is not considering a safety issue nor doing a recall. However, I was told I should not drive the car and have it towed. So, if my car can catch fire while driving from a faulty amplifier, that would be a safety issue. I was told this would be an out of pocket expense.

It was here the entire 30days warranty I had. Im upset! It was smoking and cracking and making all sorts of noise along with the horn and buttons do not work. Mercedes says no way to fix this and can not drive this unsafe car. I have not had this car 10 full days!! Its still there. They are saying I should pay for this and it clearly states that mercedes will. Help!!!!! My car was in motion. My car is still at the dealer for this issue help!!

I had been driving on the freeway, got off onto a side road and when approaching a stop light while braking: my car completely died (while in drive). The motor shut off, the electrical dash system lights all went off and the hazard triangle system came on (with the symbol of an exclamation mark(!) inside the triangle). After about a minute and a half, I put it in park, and it restarted. Scary! I had a full tank of gas.

I leased my vehicle in november of 2013. The vehicle is driven to and from work and in the beginning I never had a problem. A few months ago I was driving down the freeway at 70 MPH and all of a sudden the check engine light came on and the vehicle lost power. The vehile would violently shake whe trying to accelerate. I manged to continue to drive for about another 30 minutes and made it to the dealer and turned the car off but once they restarted it the car ran fine. Since then then car will randomly loose power all of a sudden it has been to the dealer 3 or 4 times and they keep it for a week and then give it back and say that they were not able to recreate the issue. I have almost been hit once so far and when I let my brother use the car he was almost hit while making a left turn because of the random power loss. I have contacted mbusa and spoke with someone named juan. I continued to call him ans take the vehicle to the dealer everytime it happened expressing my concerns abiut the car as well as safety. Juan intiallly acted as if he cared but that was shor lived as he finally called back on 10/2/15 and explained that his managers and mbusa were unable to create the issue at the dealer level so there is nothing they will do at this point... At that point I realized that there is nothing that mbusa will do for me and that I will continue to forced to drive and pay for a very unsafe vehicle.
