The rims on the car cracking. I replaced the rims in the two front wheels and now the right rear rim is cracked, I have reported this previously to your commission including sending pictures. The dealer does not want to accept responsibility. In the future probably the 4th wheel rim will have the same fate.

On 10,2018 I noticed loss of air pressure on the left front tire. After inflating the tire twice, I brought the car to an authorized dealer who told me that there is a crack on the rim. After 5 day's the rim was replaced with a new one. The explanation given to me was that I hit a pot hole. This past week the same happened on the right front wheel, giving me the same explanation. This time I took picture of the rim and noticed that there 3 cracks in the inner aspect of the rim in a radial fashion. Personally I don't recall biting a pothole or anything else. The outside aspect of the rim is in excellent condition. I believe this is a manufacturing problem that has the potential to cause a major accident when you drive on a highway. The photos I took was with my cell phone but unfortunately I am not savvy enough to transfer. However, I find an expert to download and make hard copies.

After the car had been operated for ~20K miles, it was time to take it in for tire replacement. This was expected seeing as the stock tires are a soft compound tire. While at the tire shop, it was determined the front passenger rim, and rear driver side rim, we both cracked. The front had four cracks on the inside edge of the rim, and two cracks on the rear rim. After discussing this issue with my local dealer, he informed me that many customers have complained about soft aluminum rims installed on the Mercedes S class. Apparently these rims are easily dented, cracked, or punctured, even during normal operation on roads without potholes. I believe these rims are a safety hazard to not only the occupants of my car, but also to other drivers on the road. Apparently this issue has come to light in years past; just google luppino et al V. Mercedes-Benz usa. Mercedes needs to place a recall on these rims to ensure the property safety of their vehicles on our roadways.
