Hello

Just started seeing a new message on my 2010 GLK350 since yesterday .
"Power Steering Malfunction - See Operator's Manual"
&
"BRAKE - EBR, ABS and ESP Inoperative - See operator's manual"

Has anyone experienced this ?

Have been having several electronic issues with my GLK 350 since the past month & spent around 3K
- replaced steering lock module,
- From SAM module
- New battery

Any help or advise would be great.

Thanks

Planned Obsolescence?

Thanks for your response.
Manual says drive with caution, as the ABS etc. is not functioning.
Car has been with the Service specialist. In waiting mode now (:-

Any thoughts on this? Just started happening to me yesterday and I would love to hear what everyone has to say.

Just had the exact same pair of warnings occur on my 2010 GLK 350 4 Matic - 170K miles. Power steering operates ok, No physical symptoms other than two warning lights. PS fluid normal. No leaks of any kind. Thoughts?

I suspect it may just be a fuse. Will post if that is infact true.

After a month or so of tinkering and fiddling to no avail it finally went out on its own and hasn’t come back! Wish I could be more help but I don’t want to awake the gremlins.

Inspected all fuses and completed wheel angle reset (the "lock to lock" procedure) and did not resolve. Power steering is fine, no noises or unusual indications from power steering pump or reservoir. Very strange. Might be ESP Control Module which would be a pricey repair (~$2500).... more info as I have it!

I have the same problem now on my 2010 GLK 350. Normal operation, but warning lights for power steering failure and brake (ABS) failure come on from time to time. 55,000 miles on the vehicle and dealer says replacement will be about $3,000 for both modules. Dealer can't answer question as to why both modules would fail at the same time.

Had the same problem, only two warning lights, but car was ok. This is related to geometry of the car, just verify your direction, normaly will go off directly after this. There are two sensors that are misaligned and that's why we get thid error. Not to worry about, just check your direction.

Thanks for the reply, but what do you mean by "verify your direction"? Are you referring to the straight ahead alignment of the steering wheel when the car is pointed straight?

Yes, the alinigment of the wheels.

With this many lights, sound like your battery is going dead. Normally you don't get all that from a single failure unless you have a wheel rotation sensor gone bad.

They checked the battery and is is OK. Warning lights are now off.

Buy a module on eBay for a 10o$. See what happens

I experienced same problem i.e. get the message :

"Power Steering Malfunction - See Operator's Manu al"
& "BRAKE - EBR, ABS and ESP Inoperative - See operator's manual"

Its a 2010 model with 165K.. Dealership recommends not to drive and they are doing a diagnostic. ITs getting an expensive car to maintain. Just got the tie rod replaced too. The problem with an integrated circuit and parts is that if one part malfunctions, it could affect connected ones too.

Dealer in fla. could not figure what was wrong wanted $7200.00 to replace steering colum,rack and tie rods + anything that could raise the bill. I had it hauled back to Ms. Drives great for a couple weeks then when I get home next morning malfunction light may be on and steering too hard to drive but then 10minutes later will start and drive like a new car. WILL NEVER QUIT WORKING WHILE DRIVING just after you park it. Has to be electrical but I can't find it. Forgot to mention it is a 2015 GLK 350 Model which has electric power steering.

If it’s indicating a malfunction, there should be some trouble codes stored that can be seen with a scanner. A rebuilt steering rack is $1200-$1400 online.

If you have Blind Spot Assist, you likely have radar sensors behind the rear bumper cover. The wiring harness for those sensors corrodes over time, especially if the vehicle is kept outdoors mostly. Moisture will find its way in there and corrode the wiring.
Ours had that wiring and sensors replaced under warranty several years ago, no issue since.

Hello

I too started facing new warning message on my 2010 GLK300 since yesterday .
"Power Steering Malfunction - See Operator's Manual"
&
"BRAKE - EBD, ABS and ESP Inoperative - See operator's manual"
&
Run Flat Tyre indicator not operative
I restarted twice after an interval of 5 minutes ... it works but again comes back..

- replaced New battery yesterday but no use..

Any help or advise would be great. Thanks. Dinu

Did you figure it out. I literally have the exact same issue. Warning lights only without symptoms.

All of that can be triggered by a fault in the ABS sensor - a bad sensor, a broken wire, a broken or corroded reluctor ring. Anti lock brakes, brake force distribution, traction control, speed sensitive steering, and some versions of flat tire warnings are all related to the ability to sense the wheel speeds. But other things in the associated systems can also cause the warning. A scanner can help pinpoint the problem area.

Right and I already scanned mine since I have a Code/ABS European compatible reader and I got this ..


To note this is also during an issue I am trying to fix with a driver side front knock and have replaced the stabilizer bar and now onto the upper Arm replacement before ball joint investigation. On top of that we have very nasty forest fires recently and all of this came up real sudden

You probably already know this, but that’s the ABS control unit. It’s going to need initialization after replacement. I’m not familiar with that Autolink to know whether it can do that.

On a personal note, hope the forest fires get under control quickly. Emergency crews here were furiously working to put out a brush fire only a mile from the Jones Forest and maybe 1000 feet from the wooded area adjacent to our subdivisions. They were successful but it was scary for a few hours. In 2005 fires got out of control about 10 miles away and burned out some housing developments. Don’t want a hurricane or another TS Harvey, but some rain from the tropical thing would be welcome.

Yea - slightly off-topic ...
If you're south of I-10, you might see a bit of rain - north, prob not. Get the daily no-hype forecast from SpaceCityWeather. Fingers crossed on no fires (our 5 acres of pastureland here in Magnolia are brown/ dead). Home in Cypress got 6 ft Harvey water.
