Advice needed....Increasingly frustrated
All:
Could use some advice/input. I bought my 2014 GL450 with 30K miles at the end of May. During the CPO inspection, they identified a faulty strut in the rear tailgate. After some troubleshooting and 3 trips to the dealer, the tailgate is fixed. During that time, the control module for the backup camera and driver side window controls has to be replaced/repaired.
I thought all was well until 2 weeks ago. Driving to the beach, the CEL came on. Upon returning home, I took it to the dealer. The code was for a leak in the intercooler hose. Hose was replaced. I picked up the car and and a day and a half later the CEL came on again. Took it in last Friday, same error code related to the intercooler. They inspected the relevant parts and couldn't find an issue. After talking with MB engineering, they decided a software reset/update was needed. They spent the weekend doing that. I picked it up this morning and within 10 mins CEL was back on along with an unusual smell. I am awaiting the diagnosis.
I bought this car for my fiance, who has 3 teenage boys who play multiple sports so she is on the road alot. I have little to no faith in this particular GL450. I have already contacted MB USA regarding a possible buyback. They said I need to see what the latest diagnosis is.
I'd appreciate any thoughts about the buyback process as well as any general comments. Really love the car, particularly the safety features, but this particular car appears to be a lemon.

Thanks Speed for the input. I did note that the car seemed to run a little rough as the light came on. I also noticed a shudder or vibration at 65-70mph. Not sure the vibration is related as it seemed to be more in the wheels/suspension and I felt it through the steering wheel.

I am not an expert on these engines by any means, however I had a similar problem on a 15' f250 ford super duty... Shudder about the same speed. Ford mo.co. had no s.o.p. On the issue, however the mechanics and I diagnosed it as a faulty (sticky) waste gate for the turbo that wouldn't articulate fully. Made odd pressure differentials in the turbo system, causing a horrible shudder at mid rpm ranges...
Gas cars shouldn't have as much of a prob. We attributed the issue to the overly generous e.g.r. System Compliments of our friends in the e.p.a. That particular system blew quite a bit of raw exhausted right back through the intake and through the turbo.
Maybe in the waste gate?

Thanks for the input. You hit the nail on the head. I spoke with the shop foreman yesterday. They finally identified the problem: the control arm that activates the waste gate is not working properly. They are in the process of ordering the parts so hopefully that does it. They also identified a bend on the inside of the front left rim which he said was responsible for the shudder at high speed.

Update for those who are following: the entire turbo assembly is being replaced. The parts came in yesterday and they began "taking apart" (SA's words) my vehicle to install the new turbo. The vibration at 65-70 is apparently due to a dent/bend on the inside of the left front wheel. The wheel was sent out for repair.
Let's hope it does this. It would be nice for my fiance to driver her car, although she is enjoying the loaner car lol
