Replace engine, transmission, 3 suspensions is 3 years-twice on the right side Mercedes and intercar claimed that right rear air spring had a leak left rear shock leaking and claimed normal wear and tear at 71725 miles-so was the pages and pages of the link below at 71000 miles, power door locks stopped working, power drivers mirror stopped working, safety lock for back windows stop working, burns 2 quarts of oil a month, sunroof leaks, and doesn┐┐T always close all the way, ABS speed sensors defective, rear main radial seal in transmission defective, replace defective engine thermostat, replaced the batteries due to corrosion (under the seat), faulty signals for tail lights and parking tail lamps (electrical), air conditioning ambient sensor defective, replace defective radio antenna. This car has major design flaws, and has been discontinued by mb. My 2007 R350 has hit every defect listed below with the exception of parking brake, and steering column. Mercedes-Benz always claims it is normal wear and tear. I know of no car let alone a Mercedes with this many defects, I want them to buy this piece of junk back, they offered me 2000 towards a new Mercedes, I have been driving Mercedes since 1995 and never had problems like this. You would think as many of their cars I owned that they would have stepped up to save not just their reputation but O save a client. Suspension complaints: All at similar mileage, mb response was normal wear and tear. www.aboutautomobile.com/complaint/2007/Mercedes-Benz/R350/suspension.

Just brought this vehicle on 11/2014 its a 2007 Mercedes R350 woke up one morning and the vehicle was leaning to the left the front of the left passenger side was extremely low. It's very low and is not drivable. No warnings. This situation is very dangerous and I see I am not the only one having this problem. This vehicle needs to be recalled and the manufacture needs to fix the issues.

When I woke up my car was leaning to one side (the right side)...couple of times the red light (stop car too low comes on) and I have to stop in a safe area of course, but this is scary when you have your young kids with you... the malfunction light comes on when driving over 45 miles away from home.

The rear suspension began to produce a hissing noise upon parking. The next time while driving a loud release of air was heard coming from the rear passenger side and the rear end of the car slammed to the ground. Now I have to have the rear suspension replaced. This sudden failure at highway speeds, especially in unfavorable weather conditions, could result in a serious accident. Reports of problems with the airmatic system are abundant and not just isolated to my and year of car. In fact mb is currently in a class action litigation regarding the airmatic suspension in their gl line of cars. I believe the problem to be systemic and should be resolved by mb to help assure the safety of those that drive their vehicles.

The contact owns a 2007 Mercedes Benz R350. The contact stated that upon entering the vehicle, it was leaning to the passenger side. The vehicle was taken to a dealer, who diagnosed that the strut and the air spring for the passenger side and suspension kit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 75,000.

Came outside car is leaning to the drivers side.took to the shop they said it was the suspension sensor, replaced it. 2 weeks later, car is leaning again. Repair shop says its the suspension sensor in the rear. 2 months later car is leaning again on the exact same side. There has to be a faulty part in this car or a recall is needed. This should not be happening again and again especially after repairs are made.

After replacing the left side suspension airbag the day before, I noticed my car leaning to the right side as I got into it after using it once after being repaired. No warning indicator came on when I started the car. I was concerned making turns in this situation but managed to make it home. I brought the car in for service because it was obviously unsafe to drive. After replacing the suspension air compressor 3 months earlier, the left side air bag the day before, I was told that the right side suspension air bag had failed. Mercedes will not cover this repair and will not recall this known condition without being forced. They should be forced since many people are having this problem. I have had a problem with this suspension system 3 times.

While driving down the highway, a dashboard indicator displayed "car too low". we pulled over and the rear end of the car was sitting as low as possible. It was clear that there was a problem with the air bag supported suspension. On restarting, the car rose and we were able to make it to our destination. The car then, with increasing frequency had this problem. I brought it in for service and the air compressor that inflates the rear suspension air bags was replaced. This problem occurred with no warning and at highway speeds with 5 persons in the car creating an immense safety risk. Many others have reported the same issue with this and related cars for this and nearby model years. Like them, I wonder why there is no recall. Mercedes Benz will not replace these defective parts willingly and there are many of these cars driving down our highways.

Woke up one morning and my car warning light came on advising me that I had a malfunction. I realized that my car did not lift up as it should have and after waiting for about 15 minutes, the warning light remained on however; it would raise up eventually. Some days were better then others and some days I had to park it for the entire day in fear of driving it while the malfunction light was on.

In October 2012, my 2007 R350 dash indicated air suspension malfunction and right rear end lowered close to top of tire. Brought to Mercedes dealer in new rochelle, NY for diagnosis and problem was determined to be a collapsed suspension airbag component requiring replacement. Brought vehicle to my trusted and experienced mechanic who replaced right airbag and failed air compressor with new original Mercedes parts. In April 2013 vehicle dash indicated air suspension malfunction once again - this time left rear end lowered. My mechanic replaced left airbag component and failed air compressor again with new original Mercedes parts. Now both sides of rear suspension will not fully elevate to the proper level no matter what corrective action/repair is performed even after replacing left and right rear shocks. I have made several telephone calls to Mercedes customer service and my complaints were registered. The issue has been referred to dedicated Mercedes corporate troubleshooters; however, they will not acknowledge that an issue exists with the airbag suspension system and will not offer financial assistance since the vehicle is out of warranty. I have a friend who has a 2006 R350 and has experienced the identical air suspension problem. I have also met other R350 owners who have experienced the same issue. No recall or dealer service program has been issued addressing this problem.

Just woke up one morning, I went to start my car and noticed that it was leaning to the passenger side. I went to a private mechanic and he stated that the lower sensor needed to be repaired, so we did that, it cost around $350 for labor and part. I drove the car a couple of days and same problem. So the following day I went to Mercedes dealer and they told me that the suspension arms needed to be replaced, so we fixed that which cost about $600. They also, mentioned that there may be an air bag leak, but the work for that was around $910. I declined. So, six days later my car is leaning to the passenger side again. I went back to the dealer and the only thing they could tell me is that I have to dish out more money because now both of the air bags were leaking and now it would cost $1800. I am extremely frustrated. Because they obviously can not pin point the exact problem. My car is not under warranty anymore. How much should I have to pay for them taking guesses. I also noticed that my friend who has the same car has had the same problem, not to mention rare people I don't know who have the same car I have noticed driving on the street and their car was leaning to one side. There is obviously some faulty work that Mercedes did when they put this car together. Reading from your website there are many testimonials of this problem. This needs to be a recall for the M350 Mercedes. ## VIN passed ##

I just bought this car in October, 2012. One morning I noticed that it was leaning on the right passenger side. I took it back to the dealership I bought it from. They stated that it was the air bags"?/suspension? their mechanic supposedly fixed it! on 1/4/2013, I noticed that it was leaning again on the right passenger side. I have contacted a Mercedes dealership and they stated that these cars have problems with airmatic and suspension.why are there no recalls for this" the cost to fix at Mercedes dealership is over 1,500 dollars!
