Subframe is completely rotted. Taken to several mechanics who were unable to diagnose handling problems and severe tire wear. After research this is a common problem, we were never notified this could be an extremely dangerous and hidden issue. Car is unsafe to operate without expensive repairs. Unacceptable.

Subframe of the car rusted and rotted from inside out. to the point of rear suspension completely detached from subframe. it caused my car to fish tail and lose control under even slow breaking conditions. once we discovered the problem we were told the car was a death trap and was absolutely unsafe to operate. we found out this is a common problem for this MB model type. the problem was already under recall in Europe. there are thousands of existing owner complains about the exact same issue. MB USA initially refused to acknowledge the problem, but on 2/14/2023 they sent a memo to all US dealers to repair rotted subframe for free under "extended warrantee". however, they refused to pay for the full repair even after dealership specifically informed them that it was not possible to complete the repair without replacing thrust arm and rod, which were damaged due to the Subframe failure. this incident endangered me and my family, cost $2000+ out of pocket for repairs in addition to the loss of access to my vehicle for at least 3 weeks.

My transmission began leaking fluid with 22,000 miles on it and now the transfer case needs to be replaced because it is leaking transmission fluid. I was driving up a hill and my SUV felt like it was skipping gears. The next day I noticed red liquid on the garage floor. It was towed to Mercedes service department in hoover and supposedly fix. However, the transfer case is still leaking.

To whom it may concern: I recently took my 2010 Mercedes glk to my longtime mechanic, kevin brady of brady's automotive repair in laguna niguel for service and a smell of gas vapor in the passenger cabin. Upon further inspection he found a fractured plastic cover plate as part of the fuel filter system under the rear passenger seat. I have included a picture where you can clearly see fuel having soaked the exterior of the cover plate. Kevin replaced the defective part with with oem parts at a cost of $282.60. Upon further review I found a similar component for which the cover plate belongs to as subject to recall 12V557000. The recall is for the same make and model of vehicle with the same part recall called for causing the same issue as the 2011 model recall. My model is just one year prior to the referenced recall. It appears Mercedes's defective part is a bigger issue than the previous recall let on. Fuel and vapor should never be allowed to enter the passenger cabin. I retained the defective part for further examination. I contacted Mercedes Benz about the issue. I offered to allow them to examine the part and asked for a reimbursement of my $282.60 (I did not condition the examination on the reimbursement). They refused and gave me a corporate legalese response. So I turn to you for help. Thanks in advance.

"takata recall' is the current top concern to date with my car. I was sold a used lemon & would never purchase another Mercedes based on my experience. I bought the car in October 2015~ it has been back to the dealership approximately 10 times. Some visits the car was there for 2 plus weeks. Mercedes put the wrong tires on the car causing alignment problems, tires wore down after 3000 miles, there is an unresolved condensation leak, unresolved oil leak, & currently have a SRS diagnosis code which has been left undiagnosed.

The problem is a faulty ball bearing in the gear box behind the transmission, and I was quoted a price of $6,000. I feel as if this is a recurring problem with this particular vehicle, and no customer should beheld financially liable for the cost of fixing or having the problem resolved.

Intermittent warning "check right tail and brake light" I check and light not functioning; message disappears, lights work and then repeats with light not functioning. Additionally car fails to start on several occasions. Has been in shop 3 days. Not sure if it is wiring harness faulty, circuit board, perhaps harness or sockets burnt, melted. Note that this problem is rampant in online reporting. Mercedes reports no recalls.

2010 Mercedes benkglk 350. On Saturday, October 16, I was attempting to reverse out a parking space in the westfield shopping center, wheaton, md. I put the car in reverse and reversed slowly. I then put the car in drive and moved forward to do a 3 point turn.. placed the car in reverse and it stalled for a few seconds then lurched backward, hitting another car. This is not the first time I have noticed this behavior but it is the first time it lurched so hard that it literally jumped one full car length and hit the car. I went online and noticed a few reports detailing the same behavior. Is this a common glk problem and if yes, what are you doing about it.
