The contact owns a 2019 Mercedes-Benz CLS53. The contact stated that the passenger’s side rear rim was cracked. The passenger’s side front rim was also cracked.

The manufacturer was contacted and referred to the NHTSA Hotline. The failure mileage was approximately 66,000.

My car started shaking and after putting it on the computer it was an electrical wiring harness issue. I was told it will be 6 k to replace both harnesses. It’s been 8 months and they just received the part. The service tech told me that these cars have this issue due to the position of the harnesses being to close to the exhaust. It dries out the wiring. I went to the Mercedes forum and found numerous complaints about this issue. Recently I baited the Mercedes of downtown Los Angeles and was advised they received another cls 450 with the same issues as myself and several other owners of the cls 450. I have been getting the run around for months. This should be a recall as even if I pay 6k it will happen again! Please help. I even reached out to BBB and the dealership never responded to them. I’ve been in contact with Mercedes head quarters and was advised to reach out to NHTSA

I understand that this problem has been encountered by many, many MBZ owners.

The contact owns a 2019 Mercedes-Benz AMG CLS53. The contact stated while driving 60 MPH on a bumpy road surface, the vehicle started shuddering. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that an unknown wheel had cracked and needed to be replaced. The vehicle was repaired; however, the failure recurred several times while driving. The contact stated that the vehicle was taken to the dealer on several occasions, and the four wheels and tires had been replaced; however, the failure persisted. The vehicle was taken to the dealer, where it was diagnosed that the front passenger's side wheel needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 20,000.

I had a slow leak in the rear passenger tire for a few weeks now so I took it to the neighborhood tire shop. No nail or puncture was discovered but a hairline crack in the rear wheel. The tire shop manager advised me to call the dealership and ask the part to be replaced as this is a very low mileage vehicle. The crack according to the shop is definitely a defect in the wheel as there was no evidence of impact damage. I contacted the dealer for a warranty replacement as it should be covered under my CPO warranty coverage and they will get back to me. In the meantime I did some research and found several MB Forums that stated the same issue with the CLS 450 and CLS 53 AMG. The forum stated that the issue is with the run flat tire combined with the original factory wheel. Most of them stated that because of the hard sidewall of run flat tire, the pressure causes the wheel to have hairline fractures as American roads are not as perfect as German highways.
