Vehicle keeps losing air, steering wheel hard to turn, car leaning to right side, airbag lights keeps coming on, the car looses power when turning. During the night car will lower it self. ABS will come one, smell smoke. Was told by dealer I have leaks in the engine, had to repair suspension, and different struts and parts while during warranty and after spending thousands of dollars. I notified mbusa, and apparently this car has been having airbags and suspension issues repaired before I bought it, the previous owner has been doing the same repairs. Within a month of repairing on thing, the car starts to lean to right, make noise, leak fluids from who knows where.

Since Dec 2017 the car presented steering problems at slow speeds, loss of power and hard to turn. Took it to the dealership that informed me that there were no issues. I did find in the glove compartment a receipt from a previous owner in which they replaced the power steering components in late 2016. It seems that this is a recurring issue with the car based on the many reported instances on this website.

Me and my wife own a 2008 Mercedes-Benz gl-450. It started generated power steering problem on us since July 2017. During any driving time, when we step the brake to slow down speed, the power steer becomes very hard to turn regardless its on freeway or local street. The steer takes tremendous effort to control on lower speed and makes it specially hard to park. We took the car to a local mechanic for a check up since the warranty has expired. The power steering fluid level was fine and it might encounter a power steering pump failure according to the mechanic. Due to the mechanic's research later on, he discovered that there were a huge numbers of recall for the same power steering problems on the same model, same year of our car. With the suggestion of the mechanic, we checked the recall information on Mercedes-Benz official website with the VIN. It came out our car is not on the recall list. Then on Feb 6, 2018, I called Mercedes-Benz recall hot line. The person who I spoke to refused to give me any information but a "no" answer. The same day when I spoke to Mercedes-Benz customer service, the gentleman named "will"(if I remembered right) was very nice. He told me that he will write a report of my complaint but he was not able to guarantee me anything. We are writing to your department to find out if we still have any justifiable legal right with our vehicle.

I have a 2008 GL450 when you make a turn you'll hear a sound and it is so hard to turn the steering wheel. I took it to a Mercedes Benz mechanic and they flushed and replaced the power steering fluid, the wheel worked for a couple of days and the noise is not as loud but 2 weeks later the steering wheel is hard to turn again and the noise is loud again.

Vehicle goes on one side, dealer blames and repairs struts, same issue happen after 5 months, and dealer blames air suspension bellows. Stiff and noisy steering may also be related to takata recall.

Power steering fluid is leaking at top seal at input shaft on power steering gear. It leaks onto bottom of chassis frame and concerned about catching fire due to exhaust pipe nearby. This is noticeable when vehicle is parked overnight as it leaves puddle of fluid underneath. Power steering reservoir was also leaking and was replaced at 74,000 mi.

Was notified by Mercedes dealership that the car had "possible steering rack control head leaking. Fluid could be spatter from reservoir leaking." I was told to "replace power steering reservoir and seal ring, " which I did. Less than 20,000 miles later, the car became intermittently hard to steer. Within a short time period, the car became worse and, because it was unsafe to drive due to the unexpected inability to steer, I drove to the dealership service department without an appointment. I was told that now I needed to replace the power steering rack, and replace power steering pump and reservoir. An online search brings up hundreds of similar complaints with the 2008 (and similar years) GL450 power steering.

Purchased 2008 cpo gl-450. Unfortunately for me I have had numerous incidental/consequential repairs which does not coincide with the marketing specific performance. The following are the current repairs: Crack in rear bumper 10/22/12, faulty rear hatch 11/01/12, faulty door 2/4/13, engine piston leak 3/5-19/13, , system stereo/navigation failure 5/13, fuel smells 7/6/13, steering wheel replacement 3/14, garnish molding replacement, air pressure shocks malfunction 3/14, and seat belt failure 6/14. And I am to believe my vehicle passed a cpo inspection with all these noticeable failures. As a consumer, I was willing to sacrifice extra costs for quality and reassurance; instead I experienced a defect in ??truth-in-advertisement. I have 4 months left on my extended warranty(you can only purchase Mercedes Benz warranty if you buy a cpo Mercedes Benz vehicle ;which are extra added fees to the cost/price of the vehicle.), if not properly addressed, I believe this type of exceptional circumstance of auto sales/performance and business practice will grow and transfer severe financial hardship on any/ and all consumers.

Power steering failure. Dealer resealed rack head assembly and replaced power steering pump. It's unclear to me how a sealed reservoir and related parts are leaking when it was designed by the manufacturer as part not subject to wear-and-tear deterioration. My research revealed NHTSA campaign id number: 08V682000 but dealer said it did not apply to my VIN.

2008 Mercedes gl 450 steering sporadically locks up and causes loss of control of vehicle. Brought into dealership. Was not occurring when dealership evaluated and they failed to diagnose any problem. No problem for about 3-weeks after dealership visit. Steering now locking up again. Occurs at slow, medium and fast speeds. Vehicle very difficult to steer and steering wheel difficult to turn. Almost feels as if there is a loss of power steering control. When steering locks up the steering wheel turns with extreme force and jumps from one position to another.
