Excessive Tire failure on "AMG" 21 inch wheel and tires. Pirelli tires have replaced 4 tires in four months. cracks in side wall bubbling.

I purchased this car as a certified pre-owned vehicle from Mercedes Benz in December 2024 with 14,000 miles on the odometer. This vehicle has factory 21-inch AMG rims. Since that time, I have had to replace 5 tires on this vehicle, all from Mercedes Benz dealerships. I purchased an additional $2,000 tire insurance policy from Mercedes Benz due to this recurrent issue. Due to the size of this rim, these tires are extremely prone to blowing and flats. Furthermore, this vehicle does not come with a spare tire or even with a storage compartment which can accommodate a spare tire. I was under the impression that this is because Mercedes Benz equips these vehicles with run-flat tires, however I recently learned that Mercedes does not offer run-flat tires on the 21 inch rim, leaving customers with no choice to but have the vehicle towed each time a flat tire occurs. I have been stranded on the side of the road 3 times within the past 3 weeks alone. Other customers have experienced and reported similar issues with this vehicle.

I purchased this vehicle used at a dealer in Virginia. I drove it home to Chelsea Alabama, outside Birmingham. After a couple of days, my front right tire went flat. I took it to the dealer and they said the flat tire was caused by a cracked rim and required both to be replaced. Almost $3,000 for tire and rim. I continued to drive the car, maybe 4,000-5,000 miles and I had another tire go flat. This was the drivers side rear tire. This was a Pirelli 285/35 R20 run flat tire. Again when I took it to the dealer, this rim was cracked and also needed to be replaced along with the tire. $2,790. The car has 55,000 miles and is meticulously maintained. And I do not drive on rough roads. The dealer consistently states it was due to “hitting a pot hole” which a) is not the case in both these incidents, and b) a rim should not break from running into regular small imperfections in the road. I’ve been in the auto manufacturing business for 38 years and have never, ever had a rim fail, not once but twice in 4 months on the same vehicle. After investigating, this is happening all over. My feeling is the rim has not been sufficiently designed to support the weight of this vehicle. And now, every time I take the car out, I fear for my life and my families life. Frankly, the car is not safe because the rims can and will crack and split under regular driving conditions! This can cause a blowout and possible injury or death. This cost and the cost of my safety should be covered by Mercedes. They should replace these rims with stronger, more properly designed rims to ensure my families future safety!

I’ve had to replace six tires due to blowouts from hitting small potholes, something I’ve never experienced in the past 40 years of driving other vehicles! This seems to be a manufacturing defect in the vehicle, as the tires can’t support the weight of the car, and any pressure on them causes them to blow out. I’m now hesitant to drive long distances, fearing that one or more tires could blow out at any time. Without a spare tire in the trunk, I’m left stranded. Below are answers to your question: 1. The tires failed, yes they are available for inspection. Also have photos of the damaged tires. 2. The safety of myself and my passengers is at risk, as a tire blowout while driving at 55 mph could potentially cause the vehicle to lose control and result in a serious accident.. 3. The problem has been confirmed by an independent service center. 4. The vehicles tires have been inspected by an insurance representative and independent service center 5. NO

While on the freeway, going approximately 70 mph, the vehicles onboard cameras all failed and I got a warning that said “camera dirty/unavailable/traffic sign assist currently unavailable”. Because of this failure, I almost crashed the car in Front of me. I cleaned all the cameras. The message continues to appear. The dealer said “it’s a known malfunction with this particular model, based on the chip shortage, during Covid”. My car has 57000 miles and apparently several owners of this model, are experiencing the same issue. Dealer wants to charge $1,800.00 to fix a vehicle safety feature, that shouldn’t fail this soon.
