The best to fix it is REPLACING THE CAR!!!
I changed it last November for a 2011 GLK350 Fantastic Ride and build like a tank, proudly made in Germany! absolutely no problem whatsoever.
I lost money on the R350, they updated the software, and some other things but they could NEVER pinpoint the random shifting problems and shake ups.
This adds up to alternator problems, early serpentine failure, battery failures, the panorama roof slowness, the random tailgate light problems, etc.
And the last one before I traded in, the taildoor shocks were broken. Bill to fix those around a $1,000 that is when I decided to trade it in.
 
Mercedes Benz dark ages of electrical problems between 2001 until 2007, especially the ones assembled in the USA.
Finally in 2008 they increased the quality again.
2006 R350 first batch of R350s it is like the Gremlins built those cars. I would stay away from them.

I agree with the previous post.
 
We got rid of our R350 (first year model) and we've been happy since! There were just too many electrical problems that it wasn't enjoyable car ownership with all these trips to the dealership for the annoying myriad of problems, mostly electrical.
 
It's a shame as most Mercs do handle well, although my grip of the R350 besides being a bit underpowered for the weight, is the dim standards headlights (I couldn't get one with the HID lights with the one I bought at the time..)
 
How are the GL's in terms of reliability and lack of trouble??? Test drove one and it was fine. How about the E350's??? Hadn't dared consider buying another Merc because of bad experience with our R350.

I've had my 2011 GL450 for 3 months. I've had two significant problems so far, both electrical. The a/c intermittently quit supplying cold air, and the tailgate sometimes closes as desired but then opens, for no apparent reason. This has happened at least a half dozen times. I haven't gone to the dealer for the tailgate problem, but the a/c was fixed after several days in the shop. There have been a few other signs of electrical gremlins, too, but things that have occurred only once. My guess is that MB has not exorcised the electrical problems from these vehicles.

Hi There,
 
I'm curious, what prompted the steering column replacement? I have a 2006 R350 and I'm starting to get a clicking and thumping that I can feel under the front floorboards when I make a turn. I'm trying to pinpoint the issue before taking it to my MB dealer. I'm glad I took out an extended warranty, I'm having lots of problems (I'm happy to post the list of issues if anyone is interested) including some possible transmission issues I love Mercedes but these issues combined with a lack of courtesy and friendliness at the dealership are making me wonder whether I'll ever buy another benz...
 
Cheers,

My R350 cut off while driving on the hwy, was able to pull off to the side. Turned car back on and it would't go into gear, drive or reverse.

Hi,
Did you ever have a problem with the r350 not shifting into gear?

Yesterday my 06 r350 cut off on the hwy, was able to get it to the side of the road. It turned back on, but would not go into gear, drive or reverse. Got it towed to my house, haven't took it to the dealer yet. Its not under warranty anymore, so I'm trying to see how much this is going to cost me. I've been reading alot of the same stroies, so I'm thinking its a low voltage issue, I hope.

My 06 R500 did exactly the same thing last week. Have you had anyone look at yours yet? What was the outcome?
I took mine to MB dealer and they said I needed a new tranny (for $8200)! I'm getting a second opinion today.

#45 of 63 R350 battery - jumpstart by springqueen

Nov 29, 2011 (9:39 pm)

Hi, I just spent 6 hours today waiting for MB roadside assistance, and finally getting my 07 R350 towed to the dealer. The battery was dead, ( I think I left the parking lights on, but had problems for a month now with malfunctioning headlights) and the mall security folks tried to jump it off, using my manual to guide them in the correct points of contact. They used the wrong point - positive to positive, and all kinds of lights and warnings went off, and car would not budge out of park. Dealer service says it may have blown one fuse, or worst case: blown one or more of the computers on board. If so, big bucks > Anyone have experience with non-authorized or non-dealer battery jumps and had problems?

My car is at the MB, I had it towed there Tuesday, haven't heard back from them yet.I am scared to hear the outcome. Who has 8200 dollars to spend on a car to get fixed. That's just crazy. Did you get your second opinion yet, please let me know. I should hear from the dealer today and I will let you know. Do you plan on keeping your car, or should I say, do you plan on staying in the Benz family.
