The battery Warning light was on and the radio was not working either. I had the vehicle inspected by the Mercedes dealer and was told the batteries were being drained because the BCM (Battery Control Module) I was told there was nothing they can do because Mercedes discontinued the replacement parts. So I started to investigate the BCM https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-2096196 Fri, 30 May 2025 00:00:00 GMT When pulling into an intersection after stopping at a 3-way stop the car unexpectedly went into neutral gear. An oncoming car had to stop suddenly to avoid a collision. I was able to shift the car back to drive and got it home. Now the car will not start and there's a warning message on the dash saying to get the car to a dealer. The car is now at the Mercedes dealer. Apparently the problem ex https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-2078064 Fri, 28 Mar 2025 00:00:00 GMT 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 https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-2065180 Thu, 13 Feb 2025 00:00:00 GMT Complete brake failure while driving. No one was injured but the vehicle could not be stopped until the transmission went into limp mode with still no brakes. Now the ABS and SRS lights on. Brake pedal to the floor. I completely have new brakes speed sensors fluid exchanges and more. The current recall doesn’t seem to cover my vehicle. I contacted the dealership and they said there are no open rec https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-2046692 Mon, 09 Dec 2024 00:00:00 GMT 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: 16V8 https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-1997622 Fri, 07 Jun 2024 00:00:00 GMT 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 https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-1982919 Fri, 12 Apr 2024 00:00:00 GMT 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 https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-1875879 Fri, 24 Feb 2023 00:00:00 GMT The contact owns a 2011 Mercedes-Benz SL550. The contact stated while driving at various speeds, the dashboard suddenly illuminated red indicating that the tire air pressure was alarming. The contact also felt an imbalance with the weight of the vehicle as if one side of the vehicle was lower than the other. The contact discovered that the rims had fractured. The failure had occurred while driving https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-1856941 Fri, 02 Dec 2022 00:00:00 GMT This particular model 2009 Mercedes SL 550 hardtop convertible 5.5 liter motor has two batteries and accessory battery that battery that’s located in the trunk in the main starting battery that’s on the firewall. These batteries are both new in OEM recommended. If the car sits for 24 hours, it will not start. The electrical system is completely drained.

The seam around the vent is peeling up, the top part is looking really bad. The top part of the instrumental console, the leather cloth has fell and you cannot see the face of the panel.

The color is great, just coming aprt from the seams. https://plaincars.com/make/mercedes-benz-sl550 https://plaincars.com/make/mercedes-benz-sl550#complaint-1840194 Mon, 12 Sep 2022 00:00:00 GMT The contact owns a 2007 Mercedes-Benz SL550.
