Mercedes-Benz
Sl-Class

I was driving on a country road when all of a sudden my car lost power all the warning lights camo on the dashboard. Smoke started billowing out from the back and front of the car. It turned off and I only coasted about a 100 feet. I could not safely pull off to the side of the road as the car had no power. Thankfully the road was not very busy and the tow truck collected the vehicle. Upon further inspection I saw a lot of oil on the road and the mechanics were able to confirm that the engine block was cracked and there were 2 large holes. Upon further research I was able to find a lot of similar cases with this specific M278 Mercedes engine and premature failures that happen because of bad cylinder coating. In later engines they update the cylinder lining to a more durable steel sleeves. I think this is a very well documted issue and a huge safety risk. There is a class action lawsuit running about the M278 engine and I think you need to get involved and hold Mercedes accountable for their poor design.

The contact owns a 2013 Mercedes-Benz SL550. The contact stated while driving at an undisclosed speed, the vehicle lost power steering assist functionality. There was no warning light illuminated. The vehicle was taken to an independent mechanic, who determined that the steering rack needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 16V899000 (Steering); however, the VIN was not included in the recall. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 60,000.

Had some issues with turn signals and a check engine light. My car is a 2013 SL63 AMG with 22700 miles. It sits in garage 95 percent of the time under cover. Took car to dealer and they replaced both batteries it fixed al of the lights except my turn signal. I asked the dealer why didn't you check the turn signal I got no response. I had to drive to Louisville the next day and on the way home I noticed my headlights were out and had to drive 75 miles with only fog lights. I took it to another mechanic who took the bumper off and was shocked and how much water was in my headlights and in my electrical components. He said I'm lucky the car didn't shut down or catch fire and sent me pictures of water and a brown sludge he said was some kind of manufacture fix to absorb water in the lens. He said he has never seen anything this bad on such a nice low mile car. I told him I have complained to dealer many times over the years about fog and water in my headlights and every time they would say its normal it will evaporate out of the lenses. But it also left spots and dirt inside the lenses you cant get to clean. It was so frustrating they would do NOTHING about it when I was under warranty. I researched online and found many other similar complaints with jerry rig fixes the dealers would try as they never want to replace the defective headlamp as the cost to much. This is a manufacture issue and they know about it and they just push it under the rug because they don't want to pay for the recall to fix all these cars. Its sad where is the quality anymore and the safety for consumers. I read a blog where the water shorted out his computer and he lost all controls of car steering and everything. Sad that they take profit of safety for it customers.

The rear subframe experienced excessive levels of rust which caused the rear left side to suddenly collapse. After the collapse, the car would fish tail at low speeds (i.e., less than 15 miles per hour). I am thankful that the collapse did not happen when traveling at higher speeds such as an expressway, which would have certainly caused an accident. The Mercedes Benz dealer refused to cover the cost of the work to replace/repair the subframe. The dealer stated that they would cover the cost under an “extended warranty” if the car was manufactured for the US, but, as I found out, the car was made for Canada based on the VIN #. This is the case even though the subframe in this model had the same rusting issue in the US and in Canada. Additionally, I purchased the car in Florida. I am surprised that there had not been a full recall on this issue especially since it appears to impact over 500,000 Mercedes cars. Drivers are on the road with this issue and are unaware of this issue unless they happen to bring their car in for service specifically for this issue. Additionally, not honoring the recall for the car because it was made for Canada even though I am a US Citizen, the car was purchased in the US, and the car operates in the US does not make sense. This issue is a hazard on US roads, and should be proactively communicated and remediated. Not doing so poses a safety issue. I am further surprised that the Department of Transportation has not taken an active role in this issue.

Started the vehicle and used the gear selector to shift to Drive. Car did not go into gear. Towed to dealer. Dealer found faulty “ism module.” Apparently a very common issue with these cars. So common that the part is in an “indefinite back order.” The replacement part is also revised because Mercedes knows there was a manufacturer defect with the existing part. I am being charged more than $1600 on a part that the manufacturer has already acknowledged was faulty and created a replacement for it.

Our power steering went out all of a sudden. We took this to our mechanic who said it was a recall for the power steering. Fletcher Jones Mercedes' looked at the vehicle did a computer update recall and said the power steering is not covered. The car is very unsafe and we need this fixed.

Cam sensor seals failed which leaked oil into the wire harness, O2 sensors, and ECM. This happens to be a common problem with M278 engine. The repair was $10,217 to fix this issue. The car would not pass emissions without this repair. Could oil into the electrical system pose a fire hazzard?

The contact owns a 2013 Mercedes-Benz SL550. The contact stated while the vehicle was being serviced at a tire shop, he was informed that the power steering assist warning light was illuminated. The steering wheel became difficult to turn. The contact took the vehicle to the local dealer to be diagnosed. The contact was informed that the steering assembly needed to be replaced. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 16V899000 (Steering) however, the VIN was not included. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 65,000.
