Received call from dealer advising that MB had issued a service bulletin/recall for all GL's with off road package. Car had to be brought to dealer to have sway bars replaced with new units, allegedly same as used on GL AMG.

Anyone else contacted for this?

 

Not so far, mine has off-road pkg and the active curve sway bars on 2014 GL450. Did they call you just in the last week or so?

 

Yes, this past week & our GL550 has both Off Road and Active Curve-BTW, a great automobile.

 

Fab, do you have any info on this recall-replace sway bars on GL's with Off Road-allegedly with AMG bars??

 

Any update on this?

I bought a new GL550 on 10/24 out of a dealer's inventory. It has active curve system but does NOT have off road package.

At around 200 miles I got a malfunction message for the active curve system. It cleared at the next start up.

At 500 miles I started to notice rattle or clunk in the front end (I think) over small bumps, particularly at around town speeds. To me it sounds like something is loose, maybe sway bar or related hardware. Definitely not a normal sound for a $106k car!

Car now has about 1000 mikes on it and I'm planning on taking to dealer when I get a chance. Unfortunately it is 90 miles away.

This is the first I've heard of any service bulletin or recall...sound like it may explain my rattle.

 

Had the same issue on my GL450 after about 2K miles on the clock. Brought it back to my dealer, first they changed the right side strut. Clunk did not go away. Then they kept the car for about a week investigating this and changed something - clunk disappeared. I don't know exactly what they changed, but if you'll have a problem to locate the issue - I can contact my dealer to browse my exGL history. BTW...my 2011 GL had the same clunk sound...dealer was unable to figure out what was wrong..

 

If you wouldn't mind asking, I'd very much appreciate it. I'd hate to be without for a week while my dealer struggled aimlessly

Thanks for the offer to help.

 

No problem....Currently a little busy with work, but I'll try to talk to them till the end of this week...

 

Sorry - about the delay - my efforts were elsewhere.

On GL550 with Active curve - there is a TSB alert regarding inspecting the hydraulic pump.

On GL550 Off-Road - no specific TSB.

I think the original dealer "report" was kind of muddled in the way they communicated.

 

Interesting…

I called my dealer on this. They checked and got back to me saying the opposite…that there's a TSB for off-road package and nothing for active curve system. Hmmm….

 

The TSB I saw on the off-road package has to do with Star diagnostic update settings for the shop equiptment .. not with any mechanical.. like I say the TSB for off road I saw..
