Defect investigations
Loss of rear lighting assembly
The Office of Defects Investigation (ODI) opened an investigation based on consumer allegations of loss of rear lighting in model year (MY) 2008-2011 Mercedes Benz C-Class vehicles.Complainants alleged that one or both rear lighting assemblies fail to illuminate (i.e., all lights housed within the assembly extinguish, including the stop, tail, and turn signal functions) or illuminate dimly.In some reports, complainants also alleged that the failure was accompanied by a burning smell emanating from the trunk of the vehicle.When examined, these vehicles showed evidence of overheating at the lighting assembly harness connector, including damaged (blackened) wiring and plastic.The rear lighting failures typically involved one side of the vehicle however in some cases both assemblies failed (although probably not simultaneously).ODI identified 5 fire and one injury allegations during the course of this investigation.Two fires occurred while the vehicles were parked.One originated in the vicinity of the driver?s side light assembly where the fire and associated damage was confined to the trunk area, and the fire self extinguished due to oxygen starvation.As a result of the fire, the vehicle was repurchased by Mercedes and salvaged.The second fire originated on the passenger's side and required fire department response to extinguish; the fire damaged the tail light and surrounding body panels as well as the trunk area and wiring.The vehicle was repaired and returned to service.Two firesoccurred while the vehicle was being driven.In the first instance, the driver detected an odor and pulled over to observe smoking and a small flame at the lighting assembly wiring in the trunk.The owner was able to extinguish the fire before any significant damage occurred.In the second instance, the driver smelled smoke, pulled over, and opened the trunk to find smoke and sparks emanating from the forward facing side of the tail light.The driver was able to extinguish the sparks and drive the vehicle to the dealer. A fifth fire was reported by a fleet manager who observed a vehicle with fire damage originating near one of the tail light assemblies.The injury incident occurred when a technician burned their hand while diagnosing a failed light.The technician touched the tail light wiring which was hot enough to burn him although the injury did not require medical attention.On April 10th, 2014, Mercedes notified ODI that it would conduct a safety recall to remedy the rear light assemblies in approximately 252,867 MY 2008 - 2011 C-Class vehicles including the C300, C350 and C63 AMG models.Each rear light assembly has separate bulbs that act as brake, tail lamp, backup and turn signal indicators.The bulbs are mounted in a bulb carrier which uses a common electrical ground circuit at the harness connection.According to Mercedes, oxidation due to the use of dissimilar metals on the harness and bulb carrier electrical connectors can result in increased resistance and a subsequent dimming or loss of lighting function.The heat caused by the increased resistance/oxidation can also lead to the melting of the surrounding plastic, or in some cases, present a fire hazard.In conducting recall 14V‑171, Mercedes dealers will inspect the left and right bulb carriers and harness connectors for the presence of dissimilar electrical connectors and/or evidence of related thermal damage; affected bulb carriers and/or harness connectors will be replaced free of charge.Mercedes notes that service replacement bulb carriers produced from January 2012 eliminate the dissimilar metal condition and that these bulb carriers will not requ

What 2008 Mercedes-Benz AMG Cls63 owners say
Most recent owner complaints, unedited.
A cast aluminum wheel on my 2008 mercedes benz cls63 amg cracked due to a casting defect. In the inside lip of the rim of the wheel at the outer diameter is a void, or hole, that was created by a an air bubble that was entrained in the molten metal but could not escape the mold before the metal solidified. This void makes the radius of the wheel at that point weak and susceptible to cracking under normal operating conditions. I am entering this complaint regarding the casting defect in order to present information that proves mercedes-benz must replace one wheel on my vehicle. The USA consumer action handbook contacting the federal safety agency is suggested. The handbook made one thing clear, the federal safety agency law states, if a safety-related defect exists, the maker must fix it at no cost to you, even if your warranty has expired. To be fair, I am only asking mercedes-benz reimburse me for the unsafe wheel with a refurbished one costing $450, rather than a new one costing $1200. Have further substantiation that mercedes-benz wheels are prone to cracking: a study of the federal safety agency complaints from 2000 through 2011 reveals that for manufacturing defects in wheels: audi had 1 complaint, cadillac had 2, bmw had 14, including a recall campaign for defective wheels (00v383000) mercedes-benz had 47. Mb replaced a number of these wheels that were out of warranty as described in the federal safety agency complaints. As defined in the USA consumer action handbook this comprises a warranty, therefore my wheel is covered also. Mb has a 1 year / 12,000 mile warranty on wheels. Wheels are not covered under the basic bumper -to- bumper warranty as are by audi, bmw, gm, ford, chrysler, toyota, honda, and hyundai. In light of all of this evidence, and the law, please have mb reimburse me $450. (mercedes-benz customer support, 3 mercedes-benz drive, montvale, nj, 07645).
A mercedes-benz 2008 cls63 amg has four oem cast aluminum wheels with large casting defects in the form of debris collected at a knit line around its circumference. The other three pictures show the knit line as well as mold debris. The deformity, or knit line, is the location where the two mold fronts meet when the mold is filled. One of these defects looks like it goes all of the way through the wheel. This one should leak and should have been caught on a leak test. Wheels are scrap. They have another casting defect from moisture in molten al. When cast the water boils and outgasses forming pits on the surface of the part. This causes weakness. It should not happen. The vehicles now has 53,000 miles on it. These defects create a weak spot on the wheel. With the constant loading and unloading of force on the defect a crack has developed and enlarged by way of fatigue. The wheels have been defective from the time of manufacture and have been unsafe and will remain unsafe as long as they are in use. They cannot be repaired. They must be replaced. Therefore, I have asked mbusa to recall these wheels and replace them at manufacturer's expense. They denied responsibility stating the wheels are out of warranty. (wheels, it turns out, only carry a one year, 12,000 mile warranty. This tells me that mb is aware of the problem and is trying to sweep it under the table.) according to the federal safety agency complaint database id # 103234408, the owner is having repeated cracking problems with the identical auto at 9,000 miles, within warranty, and mb will not replace them. Since these defects are caused by the manufacturing process, nearly all of the cast aluminum wheels made by the same method will have these same defects. (what are the odds that all four wheels on one car have this defect?)
My car has a fuel tank leak and defective fuel sending units. A few days ago I noticed a very strong fuel smell after filling up my car at the gas station. I took my car to the dealership and they said that the fuel tank is leaking and both fuel sending units need to be replaced. I feel that this is a serious safety issue and that mbusa needs to correct the underlying problem and issue a formal safety recall.
My vehicle had 9,000 miles on it and is driven in moderation. One of the rims needed to be replaced because it was cracked - the other 3 are bent. Within 1,500 mile, I have learned that the replaced rim is now also bent. I am concerned about the vehicle's saftey while driving at freeway speeds - the car shakes. The manufacturer refuses to replace the wheels stating no defects or recalls have been issued.
