Hello. Since I bought this car in 2015. Every now and again it will go into park when driving and tge car will stop suddenly. It has done it a few times over the years and it’s quite scary. Mercedes has put me off on you, without addressing the situation or looking at the car, unless I pay first it. I think there is a mechanical defect on this car and it is quite dangerous

The steering adjustment moves in and out but will not move up or down. You can hear a clicking noise like it’s trying to move but nothing happens to the steering column.

The lien keeping assistant is stuck in operative mode. So I had a recall on my airbag and got it changed out yesterday and had the dealership check why it was on they told me I need a new steering wheel. Prior to yesterday two months ago. All the lights came on warning light and I lost power to the engine and then it will kick back on. I’m concerned because they put the airbag in the steering wheel and did a diagnostic and told me I need a new steering wheel the steering wheel pretty much run the whole car I have no horn or nothing by saying that I am afraid the airbag won’t deploy if the car loses control due to the steering wheel and electronics Yes, the vehicle has been to the dealership on diagnostic machine made aware of it and then sent me home in it on safely Yes, about three months ago. All warning lights come on and I lose power to the engine. It said something else was in operable. I got Time. Yesterday, pulling up to the dealership to get the recall airbag installed the lane keeping assistance was on. It came on parlay for weeks ago, and I haven’t been able to use the steering wheel cents. And yes, some of the other one and light pop on and off.

When driving, the steering wheel locks and I can no longer steer the vehicle, it locks in a way that I cannot move the steering wheel at all, which may cause me to crash if I am at a dead end road and need to turn. I have been trying to contact the manufacturer for resolution but have not received any responses. This was a recall back in 2017 under NHTSA Campaign Number: 17V-595 for 2015-2017 Mercedes Benz cars, with the component of Steering/Electric Power Assist System. I am not sure why my car is not listed in the recall since it does have this issue.

ON JUNE 16,2017, WHILE I WAS DRIVING ON FREEWAY, I TRIED TO SLOWED DOWN BUT IT TURNED OUT TO ACCELERATE SUDDENLY AT AROUND 85MPH, THE STEERING SYSTEM WAS MESSED UP AND I LOST CONTROL OF MY CAR , THE MORE I TRY TO BRAKE THE FASTER THE CAR CRASHED , SO IT CRASHED TO THE RIGHT SIDE AND ROLLED OVER DOWN TO THE DITCH , I CALLED 911 AND UNFORTUNATELY THERE WAS NO SIGNAL, I COULD NOT OPEN THE DOOR NOR WINDOW. THE SMOKE CAME OUT FROM INSIDE AND THE CAR CAUGHT ON FIRE , I COULD HAVE BEEN BURNT TO DEATH ALIVE WITHOUT PEOPLE PASSING BY , THEY USED A BIG ROCK TO BREAK THE WINDOW AND PULLED ME OUT OF THE CAR, TWO MINUTES LATER , THE CAR EXPLODED AND BURNT TO GROUND. THIS IS A HORRIBLE EXPERIENCE , PEOPLE LIKE ME SPENT SO MUCH MONEY ON PURCHASING SUCH AN EXPENSIVE CAR WITH EXPECTATION TO BE SAFER IN DRIVING , BUT WHEN IT COMES TO CAR ACCIDENT , THERE ARE STILL SO MANY FLAWS WHICH COULD HAVE LED TO WRONGFUL DEATH , THIS MAKES ME FEEL FRUSTRATED AND I CALLED MB LONG BEACH AND BEVERLY HILLS , THEY JUST SHOWED INDIFFERENT AND IT'S NONE OF THEIR BUSINESS . I'M NOW VERY DISAPPOINTED AND I HOPE THERE WON'T BE ANY VICTIMS LIKE THIS . I WAS THE EXCEPTION AND I HOPE PEOPLE DRIVING MB GLK350 COULD BE LUCKY ENOUGH . MB OWES ME AN EXPLANATION AND INDEPENDENT INVESTIGATION SHOULD BE CARRIED OUT , MAYBE A RECALL IF NECESSARY FOR THE SAFETY OF CONSUMERS .

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Mercedes-benz Glk-class verdict →
