GLK350 Reliability for Very High Mileage?
Just took it in for the 60,000 service today. New plugs, oil etc...$700.00. They just called and said the engine mounts are going bad $2000.00, The Differential is starting to leak $4000.00 and the transfer case is leaking $1400.00.
So much for lasting 100,000 mile....not a happy camper!
, seems like they are trying to make some money off of you.

Oil and Plugs is an 1.5 hour easy DIY plus $100 in parts. See my thread on plugs.
My Dif does have some oil sipping, but until it drips no need to touch it, the same applies to TC. I was quoted 800 to reseal the TC by dealer and indy here on MBWorld offered to do it for 400. Per the Mercedes workshop, the oil sipping is ok. So if your stuff was never wiped it accumulated over time. I do my own annual service and just wipe oil/dust off.
No opinion on motor mounts, but sounds expensive.

So how can one tell that a transfer case is leaking (vs. some other sort of transmission leak)?

Great little car, but it did need some repairs in 2020 when bunch of things decided to start going.
-Idling pulley seized and cause belt shredded - easy.
-Then crank pulley started to fail - less easy
-Then transfer case started making noise - not easy at all, but its was 300-400 in parts (including transmission service) and I didn't have to replace transmission as most dealers will tell you to do.
I just replaced waterpump and t-stat as preventive - easy
The only repair before all this was replacing the engine mounts at 90k miles, that was pain too on AWD car.
- Theromast
- Pulleys / Crankshat (Squeak was super irritating for me)
- Battery
- Ball joint
- Locking Mechanism(Driver door)
- Brakes
- Spark plugs
It has over 188,000km on the vehicle. Driven daily, Ontario weather. Parked outside. Cars aren't meant to last forever. I try to keep up with all of its service. Its the fact of owning a vehicle. Its a Benz, it'll cost you more than a Toyota that's for sure. But you can still have a lot of issues with any other vehicle. I would definitely recommend anyone a GLK. I've got it fully loaded with MB cargo box. Love using it for family trips up north.
I think it's a nice car. Would I say it's reliable? Not sure I'd say yes to that one. Mine seems to have electrical gremlins that appear once the weather turns cold. Stability went haywire once and randomly applied brakes making my car swerve left and right on a straightaway. Also had it sputter once on startup when it was only a few weeks old. Was told it was unburnt fuel in the line since I started and stopped it quickly and then started it again later.
So it hasn't been as carefree as my Civic was way back when. But all cars seem to have some small issues these days. Our Toyota minivan has had a whole bunch of recalls on it. So if you like the car then go for it. Just remember that the cost of a repair with the GLK will probably be a lot more than with an equivalent Japanese or American SUV.
I would agree that the others mentioned are also well built and long lasting but there is nothing inherent in the Mercedes build that foreshadows problems. Put both the Mercedes and its competition on a rack and compare the underside components for design and obvious strength and you will find a very solid car.
The most of the reported problems with the current generation car is in the areas of the ancillary systems that are sometimes reaching to be on the cutting edge of technology. Radar cruise control, self parking systems, and some of the advanced electronics are areas of possible problems. Putting 20' wheels on a hard driven vehicle is a problem but the standard wheels and tires are no more problematic than those of the competition.
It all goes back to the theory that there are few bad choices with today's automobile and you need to own what you are comfortable driving. There are thousands of users in remote locations that would disagree that a GLK is designed as a "city car" for limited use.
The trade-off for the comfort of the car and the luxury features will be the cost of maintenance and replacement parts. This cost will naturally be more expensive than a less expensive vehicle where the initial cost of the sum of parts is less.
I think if you find a good and reliable independent service shop after the warranty period, avoid the more exotic electronic options available, and follow the recommended service suggestions religiously...the cost is manageable.
GMC: 6.2 liter gas engine lifters crapping out at or under 20k miles, prior engine problems include plastic trays for oil direction breaking and taking out the entire valve train (see class action lawsuit for both now pending);
HYUNDAI: piston ring problem comprising about half a million cars needing total engine replacements;
FORD: took the best diesel Ford ever made the 7.3l with the infamous 6.4liter diesels followed by the even more infamous 6.7 l w/ cast aluminum pistons splitting in half, fuel injectors and entire fuel injection from pump forward self-destructing from water issues, diesel particulate exhaust literally catching fire w/ flames shooting out the exhaust pipe, EPA approved emissions wash cylinder walls with raw fuel thus diluting oil and contributing to an engine already rife longevity problems and on and on until they finally "fixed" these problems around 2010;
FIAT: Please you need me to list the issues? Just look at the BOOK of recalls; amazing
ALFA ROMEO: Why oh why did they take a name which at least had some romantic value that could have at least possibly been monetized by selling clothing into death.
MASERATI: The dealer actually warns buyers (after) to plug their cars in when they leave them overnight so the battery wont run down and the car won't start. Probably because the engine, at least the 3.7l v-6 twin turbo is shared engineering with Ferrari the drivetrain is actually quite robust, but I dare you to find a car requiring 15k a year in scheduled maintenance - including Ferrari.
