if you do reverse on a slope going up backward, GLK won't move without stepping on gas. Not sure if there is a difference in C/S mode but I find that if I am on stop/go traffic, S mode will move the car more when brake pedal is release.

anyways, any mild incline surface will put the car at rest.

I did the TCU reset yesterday. I didn't feel if it did anything or not. I will see if it helps the hard downshfits issue

My experience with the transmission has been a little different but may be attributable to the same quirks. Occasionally on slowing down, with no pressure on the gas pedal, say to turn sharply into a driveway , when pressure is applied to the gas pedal again, nothing happens. It is as though the engine has stopped or the transmission is in neutral. Flooring the gas pedal does not work too well as there is a big jerk as the transmission kicks in with high engine revs. I finally figured out that the way to handle this is to tickle the gas pedal rather than flooring it. This encourages the transmission to shift down without delay. It appears the transmission is slow to respond in these cases - scary when there is a car following. Now I have figured out a way around it there is no problem, but I will have it checked out at service time.

I'll have to experiment more, but whenever I floor it it takes off and downshifts rather smoothly. I think we also should state what mode ppl drive in. I started in S from the beginning then switched in C for break-in reasons, which I think is BS, because C puts more strain on engine and tranny by keeping rpms so low.

The only time I had a jerk is when I put transmission in N as I was rolling down the hill at 5-10 mph and didn't want engine breaking, then I put it in D and before it engaged I pushed gas pedal a bit. That produces a jerk, but I'd blame it on myself not the transmission.

The more and more I read about it, it reminds me of the Acura, with its 2 tranny failures in 10K. Hopefully this will get resolved quick, one of my reasons I sold that car was about 15km on it in one and a half year and 2 tranny failures I just didn't want the headache and worry when is it gonna go next.

I doubt we should worry as the transmission is quite old and is on many other MB models. Doesn't seem that we have a pattern yet. I use manual mode sometimes to downshift all the day to first, and all downshifts are silky smooth.

Also MB's are known for their mechanical reliability, all 3rd world countries are full of 10-15 year old MB's. So I have no worries about engine tranny or suspension.

This isn't the first time 7spd tranny has an issue, all reporting very similar coarse downshift. On other models they have been fixed with software updates.

Trans shifting hard

I would certainly mention it at your next service visit. This problem could possibly be resolved with updating the transmission control unit software. This is a problem more common to E-Class vehicles, which were resolved with software updates.

Thanks guys for the clarification on this... if I see this issue come up, i'll be at the service center pretty quick.

Tail gate

We finished grocery shopping this afternoon and I was about to open the tail gate for loading. I tried pressing the key button for at least 4 times and every time the gate opened slightly and quickly closed! This happened once or twice before but never before had it happened so many times at once. I dont' know if this is something I did wrong. If not, then surely I am not too happy about this feature, espeically I have to pay extra for it as part of the premium package.

Take it in for service and get it fixed... I agree it shouldn't be doing this, but thats why there is warranty. The crappy part is this is occuring so much early.

I have the same issue. I also thought that I was doing something wrong. I thought couple of times that it just knows that car is too close to the wall and would not open the tailgate.

You can always just manually pull it up.

Keep us posted on this issue.

it probably just needs a reprogram. i had that issue but worse, i had to have the motor replaced. apparently it is a new set for MB, electric operated with hydralic assist. or vise versa. i posted a thread about it back in march. it's been perfect since.

Thanks for the feedback. I will monitor this for sometime and if this persists I will bring it to the dealer.

SAME TAILGATE PROBLEM

-----------------------------------------------------

I too have the exact same problem with my GLK350 tailgate. It won't open properly and never has. For months it only opened partially and I thought it was me. The dealer has had the car now for 5 days and can't fix it. They now say they are contacting Germany and parts may be on back order for weeks. Now I see there are others around the USA and Canada with the same malfunction and part problem.
A big hassel!

The Squeak

Door rattles while going over bumps slowly: Turn off all AC and music. ride over bumps SLOWLY and listen to creaking sounds... its like timber grinding.

If your primiary consideration when purchasing a vehicle is reliability, then you shouldn't be looking at Germans. This is backed by JD powers. In fact, if you believe in JD Powers surveys, then Buick and Jaguars are you top choices, followed in 3rd place is Lexus.

I know exactly what I'm getting myself into when I purchased GLK; I was willing to deal with minor quirks, just like my BMW, for the great balance of engineering/drive/comfort.
My GLK350, delivered in March 2009, has the exact same squeaking issues - on the front door handles (feel and sound like cheap aluminum on plastic when pulling the doors closed) and a creaking chassis which is most obviously heard as the body flexes every time I exit my apartment via our curved underground parking ramp. My steering wheel also squeaks when turning - so all in all, quite annoying. Note: my GLK did not seem to have any chassis creaking until it received its first 6,000km maintenance check at the dealership - possible that this a coincidence? And has anyone had success in having these creaks and squeaks resolved?

Same here. Took it in and dealer adjusted "striker plate". Now it happens less often but still a not right.

I took mine to service and indicated the problem. They had both master chief looking at the problem and was able to reproduce it (its a good sign when they admit there is a problem.) They tighten some nuts and bolts, lubed as usual and claim its 90% solved and comparable to two other GLK they tested. Its been another 500 miles since, squeaks are back. Yea, its especially audible when going through uphill/downhill curves.....

and the best testament of all: close to 10,000 km on my glk and no issues yet! though i do notice that in the cold, there are minor rattles. come to think of it, for a first model year, i am very impressed so far.

^yeah old MB's were pretty bad with electronics, on top gear they drove older CL65 AMG and the light was out

knock on wood but GLK has been just like previous toyotas, let's keep it that way.

Seems like the tailgate is the main problem to look out for.
Hope the Sept 09 production run will have resolved this. I'll remember to test this when I pick it up in Oct 09.

Shade now stops short new Glk 350

I have a GLK 350 with 500 miles on it, and today I believe the sun shade is now stopping short of the reciever slots by about 1/2 an inch so you can now see a black gap front and back. Is this the norm. Can other owners tell me if their cars are the same or does the shade go competely in. Thanks
