07 GL450...Check Engine Light On

Hi, I am new here... I have 12,730 miles on my GL and yesterday my car would not get out of first gear and the Check Engine Light came on. I pulled over, restarted the car and still the same problem. I tried this a handful of times. Each time I put it into drive, it did not go in smoothly and it always stayed in first gear. Luckily I was leaving the house so I was able to get back home and not drive it for a long distance. I had it towed to MB and it is supposed to be looked at today.

Just 413 miles ago, my Check Engine Light came on and I brought it in to MB right away. I didn't notice anything different with the way it drove. The camshaft magnet A and B were replaced - according to my paperwork. Additionally, the service advisor said good thing I brought it in b/c it could have stopped while driving without warning. Great!

MB said this morning it's not a related issue - although the service advisor didn't even look at my car. Yes, my car is under warranty, but I need a little help understanding what is going on with my car! Is this something I should be concerned about with future problems? How dangerous is this?

Any input/advice will help.

Thought my questions were clear. New here and not sure if that was a dig (comes across as one). I came here with a serious question/concern and was just looking for insight from someone who may have experienced this as well.

Also, my car was at MB yesterday and the techs have no idea what is wrong with my car. Perhaps better luck today with them.

dont get offended, but here is how i interpreted your post(s):

1. truck gets a check engine soon light.
2. truck goes in for service - problem identified- camshaft hall elements replaced
3. truck gets a check engine soon light again
4. truck goes in for service - problem not identified. obviously not the same problem as before.
5. you post a question should you be concerned.

what kind of answers do you expect from an internet forum if you have no symptoms and the dealer with a starmark equipment does not know what your problem is?

i know we good - but not _that_ good

Has anyone experienced this problem? While in 'drive', car only stayed in FIRST gear while driving and would not shift to a higher gear.

Alex - I read thru some posts yesterday where some knowledgeable people identified the problem when MB couldn't. I really wasn't expecting anything, but hoping that someone encountered this issue as well. I worry that this could be a potentially deadly safety issue, if not repaired properly. I don't know jack about cars, but do want to make sure my family is riding in a safe vehicle.

Peace.

I'd say it's dangerous to the point of you possibly becoming stranded somewhere, but as a fellow '07 owner (though mine's a 320), all I can say is be thrilled you're under warranty still. I've had a couple thousand dollars worth of work done and it's taken me asking my SA to help out to avoid the full cost (I'm talking just out of warranty and needing big work done). These early production models were sometimes fitted with a few more gremlins than the later ones. But especially if you're under warranty, let MB find them and weed them out. Your concerns are legitimate, other members here with the same model/year might be able to give some advice regarding things that should be checked (i.e. have the suspension airbags looked at because my right front one blew up, that sort of thing) and your SA may be able to say "I've seen a lot of 450's come in for ..." whatever he knows.

Good luck to you!

Thanks STP for your kind reply. Still no word from MB yet. Yes, I am thrilled my car is still under warranty, but my car only has 12k miles on it - seems a bit early to be having problems! Sorry to hear about yours just being out of warranty and needing major work done. Othern than these two issues, I love the car.

I did ask my SA if the GL's had known issues, he said no. Maybe he's not being totally honest.

Seems to me that any recall is a "known issue," but perhaps your SA just didn't want to take the time. Search the forums for lists of recalls and service advisories (I know there's one you can get to online somewhere that's kept current but not really easy to understand) as well as "things" that have happened, and I think you'll understand as most here do that while MB is truly a much improved product over the past 6-7 years, they're not quite done yet.

It's disappointing to me a) I should purchase a car for so much money that's not properly engineered, built, assembled (then again, I could've bought an Alfa Romeo or a Ferrari and had the same experience) and b) a car built by a foreign car builder, inside the U.S., should present itself as something other than perfect. Though I do like the idea of owning a U.S. built car and still having a Mercedes. When I bought my only other Merc (a used 1986 560SEL - a limo by Euro standards!) the name was synonymous with absolute precision in engineering and manufacture, over-engineered in fact. I hope they regain that soon.

An '07 with 12K miles? That is pretty low miles! In any event there are some similarities to what happened to mine. Mine wouldn't shift out of 1st gear when I first drove it - it turned out that I had, without knowing it, bumped the downshift paddle on the left side of the steering wheel while turning a corner. That caused the transmission to stay in first until I figured it out. I felt pretty silly!
The difference is that my check engine light did not come on at the same time!
Every time a CEL comes on, that fact - and the cause - should be stored in the engine computer until cleared by the service department. If the SA at your dealer isn't willing to pursue the problem for you then you better find a dealer with a SA that is more helpful.
You are right however, M-B should NOT be building cars at the price point these sell for with the quality issues some of these have shown. I blame this on the bad influence of various Chrysler execs that moved over to Mercedes. It may get better (hopefully).

I know the Check Engine light could represent many issues. Ranges from a loose gas cap to a loose gas line connector (had that happened in the C55).

The '07 450 just got the CEL last Thursday, scheduled it for service this week. Stay tune....

Had the check engine light issue and it was the "magnet" issue.....replaced that and no problems since. Have not had any trans. issues............ 43,700 miles on the truck. Did buy an extended warranty so that I'm good for 5 years or 100k. All in all......... very happy with my 07!!

Of course by the time the GL is in service, the CEL goes out but at least it still recorded a fault in the "secondary air injection". MB will not perform any additional work on it as the CEL is off while in service.

SA said it's fine to drive with the CEL light on and only when it blinks that there is a major issue???
