The rear subframe of my vehicle failed at the lower trailing arm mounting point (passenger side). This resulted in the car swerving to the right when I applied pressure to the brake pedal, which was worse at higher speeds. This had been getting progressively worse for a few weeks until I almost spun out on the highway while braking. The next day, I randomly got a flat tire on the rear right side while driving at 30MPH near Valley Street in Providence. There were no warning lamps or messages prior to the failure. I immediately replaced the tire and brought it to Midas on Mineral Spring Ave in North Providence, RI, so that they could inspect the vehicle. They discovered that the rear subframe was almost completely disconnected at the lower trailing arm mounting point due to excessive rust that had wore a hole in the part from the inside-out, which was not visible at the time of the last inspection. Midas immediately informed me that the car was unsafe to drive more than the distance back to my house. They also informed me that 3 tires needed to be replaced, including the flat, as a result of excessive wear on the inner wall and the inner edge of the tread. None of these three tires had reached the wear bars yet, and Midas confirmed they would not have had to be replaced if not for the subframe defect. I had the car towed to Mercedes-Benz of Warwick after Midas replaced the 3 tires (RL, RR, FR) because I heard that Mercedes had recently extended the warranty period for rear subframes (only months after a class action lawsuit was filed about the issue). Mercedes inspected the vehicle and confirmed the issue, and is currently replacing the rear subframe under the new extended warranty program for rear subframes. However, they refuse to reimburse me for the other issues directly caused by the corroded rear subframe (which they admit liability for when they replace the part free of charge), stating they have been instructed by corporate that related issues are not covered.

2nd rim to crack under normal use [in fl, not the North East with potholes] Mercedes mechanic told us that they never should have mounted low profile tires on this rim. The tires do not offer enough protection for the rim from normal driving hazards. This should be a recall item as a cracked rim causes flats, at high speed that can be deadly

I have had 6 blow outs or bumps in my times in 2.5 years with these contiprocontact 245/40 R 18 97V tires in normal, urban driving. The rep at the dealership told me that this is a very common issue with these tires and he does not recommend them to anyone. The most recent blowout happened with I was driving 40 mph and I did not hit a pothole or bump. That tire was only 3 months old when it blew. In the previous 10 years, I had 2 blow outs on my previous. Please investigate

Repeated flat tire/tire damage while driving over small potholes in road in Washington DC metro area(small roads/highway). Frequently 2 tires are damaged on the same side.. required replacement of nine tires since 2015 with five tires changed over the last 5 months(since August 2018).apparently, low profile Continental tires(245/40R18) used by Mercedes for the E350 are known to be a road hazard. On one occasion, a "bubble" was noted during inspection of tire. I was told no other/more durable tires can be used with the E350 model! clearly, this tire model is prone for frequent failure and may present a road hazard for drivers and car occupants.

The vehicle was bought used with 10000 miles it now has approx 25000 so in 15000 I've had 6 tires changed on the vehicles do to flats. In one of the instance I got a double flat at the same time and since the tires are new on the vehicle I unfortunately had to replace the tires with the same tires. These tire go flat at a blink the side walls are thin and get sliced easly the tread part of the tire gets punctued easily and often the repair shop tells you that the flats have damage the tires and cannot be repaired so you have to buy a new one @$275. I have never owned a vehicle that has had this many tire problems. I believe these tires are defective and are going to cause an accident because they are easily damaged. There are also several complaints online about these tires and Continental not even acknowleging peoples complaints, some one needs to check these out.

I'm currently driving a 2104 E350 4matic with about 20,000miles on it, the front passenger wheel cracked from the inside. Upon further research it seems that the wheels cracking on the Mercedes is a known issue and a class action law suite has been filed in NY for the same. After contacting customer service, they said they don't have this issue in the database and they would not give me an escalation line or anyone that's willing to look into this issue to determine the cause of the problem and take care of.

While driving the air pressure notification lit up on the dashboard. Within 10 minutes I was in my driveway I glanced at the tires to see if they are low (only 3 lbs difference was lit up on the front right tire) and noticed on the front left tire that a bubble on the sidewall that had suddenly appeared which was not there earlier in the day.

While driving on the lie in New York I hit a pot hole and the tire blew out through the sidewall. This is the 5th tire within 7 months always in the front and I have replaced with new tries.I went to Mercedes service and there were 9 others in the service area with same problem. Very hole or bump the tire explodes, creating a dangerous condition of having to stop abruptly on a highway with cars and trucks. Last time I was in the hov lane and had to cross the entire highway to get off almost getting into an accident. It is to the point my wife will not drive the car anymore for fear of being stuck on the side of the road at night or on the highway. When I explained to Mercedes I was told by the service manger not to hit pot holes and they do not build the roads. I explained but you built this car to drive on NY roads and this dangerous. I was told by one of the service people that they had 40 cars come in with the issue last month. I service my car at silver star Mercedes in long island city.

The vehicle was serviced on 11/27/13. On 12/2/13 pulling away from a stop sign there was a loud pop and sudden drop to the car. After getting out of the vehicle and looking to see what had happened we noticed that the wheel had detached from the car. Police were notified right away because the vehicle was still in the road. Mercedes Benz embrace was notified directly afterwards and informed as to what had happened. The tow truck driver had to take a bolt out of each remaining wheel to re-attach the one that came off to load the vehicle onto the flat bed. Four lug bolts were missing. We did find a piece of a broken bolt laying on the ground not far from the car. The car was towed to the Mercedes Benz in memphis. I think this is a serious defect and should be thoroughly investigated to save the life of other drivers, had this happened to me on the interstate were I would have been driving at the speed of 70 mph all of us sitting in the car would have been dead and no one would have been able to find the cause. I hope you will take immediate action. Thanks
