Michelin lattitude tour 255/65r16 tires are prematurely coming apart. I have less than 15k miles on these tires and the tread is ripping away from the side walls. There is no recall from michelin for this size of tire and it has the same defect as the other sizes in the same make and model tire. This is ridiculous! 164 dollars a tire and I could have died driving on these things. These need a recall now! Peoples lives are at rick driving with these tires!

My battery was low and unknown to me the ml320 for this year loses its transponder codes in the das security module when you try to start the vehicle with a low battery. This is evidentally the third key that has lost its programming on my vehicle due to low battery voltage. Cost so far is 499 for a key, weeks waiting for the key from germany, and 300 to program it once they recieve the key. Its a dealership only item so its very very costly. This is a known problem with mercades and checking the forums it seems that everyone that has 1998-2000 model mercades all lose their transponder codes between 129,000 and 132,000 miles no matter what.this is an obvious manufacturers defect and a known issue that should be paid for by mercades. I never had these issues with my two 2002 ml500's but I will never purchase another benz in my life.

Suddenly I could not gain or get any more speed. I was just coasting along, I then arrived at my destination and got out and smelled burning smell from front wheels. I could not get out of the gear I was in.

Message display indicates left brake light not working. Replaced bulb and message disappeared for one day and then reappeared. Removed bulb and bulb was ok. Went online and found where mercedes had a brake light repair kit for this problem but I was not notified. I called the dealer and this repair kit is not under warranty or recall. I contacted a local european car repair shop who had the repair kit in stock going back to 2010 mercedes has known about this problem but never notified me or fixed the problem when I brought my car in for normal service. Very disappointed in mercedes.

Tl* the contact owns a 1998 mercedes benz ml320. The contact stated that the vehicle was being repaired by an independent mechanic for unrelated issues when she was informed that the ignition key needed to be replaced because it no longer functioned properly. The contact was not informed as to why the failure occurred. The key was not replaced. The manufacturer was made aware of the failure and the contact was informed that in order to remedy the failure, the vehicle would need an entire new ignition system. The vehicle was not repaired. The failure mileage was 180,000. The consumer discovered during research that merceds benz installed an inadequate computer system in her vehicle. The system would only allow eight keys to be made for the lifetime of the vehicle. The consumer felt it was a scam by mb to force their customers to purchase a new computer, ignition, etc, for the vehicle after the 8th key had been made. They claimed it was made that way for security reason. The consumer called two dealerships and was given a price of $4,000 to $5,000. The consumer finally had the key, computer and other parts replaced by a locksmith for $1,400. The radiator, air condition and two mirror also had to be replaced. Updated 07/11/12

Car fails to start. We had this car towed to a dealer 40 miles away from our daughter's school in mi. Needs new key system as chip not recognized and ignition system needs to be re-keyed. 8 keys have been issued to this car,(we bought it used). We only received 1 with our purchase! Everything that needs a key has to be changed. Cost estimated at $4000. We see this as a major design flaw, not a security benefit. Especiallly since their keys just quit working.
