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. http://www.aboutautomobile.com/complaint/2007/mercedes-benz/r350/suspension. *tr

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. *tr

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. *tr

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. *tr

I had to take the vehicle to the shop for repairs at least every 3-5 months since the day I bought it, which was in 2010. Nearly all of the repairs have been under warranty, it only has less than 75, 000M. in september of this year while I was driving home from work when the car started stalling jerking and shout off. the engine light, esp light and the break light came on. it immediately restarted, the engine light stayed on, while the esp and break light went off. this was a very frighten experience, hoping I won't be hit from behind. I made it to the dealer ship. The car was in the shop for 3WKS when I was told that it needed to have a tune up before any other repairs could be done, how this related to the vehicle just stopping in mid drive, IS odd.to say the least. 2 days after getting the tune up, it IS still in the shop because the engine light IS still coming on. I'm feeling uncomfortable about getting behind the wheels again in this vehicle. I expected more out of a mercedes benz with less than 100,000miles *tr

- 11008323Complaint Headlamps fogged or droplets forming. Cause Due to its outlet openings, the headlamp is an "open system". This means that acidic gases, moisture, dirt and exhaust gases can penetrate into the headlamp. This can lead to the formation of condensation on the lens of the headlamp. The headlamps comply with all applicable US standards and regulations. Remedy Check housing cover of lamp unit for natural fogging or condensation as per LI82.10-P-078301. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. Note: Order service covers and desiccant packs based on the validity description. 1. Remove headlamps. 2. Remove all grommets from outlet openings. 3. Seal vent openings with sealing profile. Important: All openings must be sealed carefully for the pressure compensation diaphragm to work properly! 4. Remove existing service cover. 5. Place desiccant packs into the new service covers and bolt down (Picture_01). 6. Glue the new diaphragm onto the intended surface at the service cover (Picture_02). Note: The bonding surface must be clean and dry. 7. Attach service cover with desiccant pack at headlamp. 8. Install headlamp. To ensure that the desiccant pack (absorption) acts effectively, the headlamp has to be air-sealed. Observe or check the following points for this: 1. Seals at the central connector must all be present and correctly fitted (Picture_03). 2. The new transparent diaphragm must be correctly bonded (Picture_04). 3. Check headlamp housing for any external damage.

- 11007974Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamps or Front Fog Lamps Leaking or Fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: Connect test adapter to pressure tester. (Figure 1) Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (picture 3). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is not leaky and the problem is down to natural physical fogging. If a pressure drop of more than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Note: Desiccant packs can be installed for headlamps that are not leaky. See: LI82.10-P-064766 Fogged headlamp, desiccant pack installed - open ventilation system LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system
- 11007790Complaint Headlamps fogged or droplets forming. Cause Due to the housing cover with pressure compensation diaphragm, the headlamps are a "closed system". This means that the headlamps are protected against acid gases, dirt and exhaust gas. However, moisture can still enter from two sources. Through absorption and desorption (the commonest cause) or through permeation. Moisture is either absorbed by the plastic material and, when the light source is switched on, it is released from the plastic by desorption, or the moisture penetrates through the plastic materials of the headlamp from outside (permeation). This can lead to the formation of condensation on the lens of the headlamp. The headlamps comply with all applicable US standards and regulations. Remedy Check headlamps for natural fogging or condensation as per LI82.10-P-078301. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. Note: Order service covers and desiccant packs based on the validity description. 1. Remove existing service cover with diaphragm (Picture_01 (1)). 2. Insert desiccant packs (Picture_01 (2)) into new service covers with diaphragm and seal with protective grille and bolt down (Picture_01 (3)). Note: One desiccant pack is required for each small service cover, and two desiccant packs are required for each large service cover. 3. Stick the supplied diaphragm onto the new service cover and attach at the headlamp. Note: The bonding surface must be clean and dry. 4. If the headlamp housing has an additional 2nd diaphragm, this must be covered over with masking tape. Note: The bonding surface must be clean and dry. To ensure that the desiccant pack (absorption) acts effectively, the headlamp has to be air-sealed. Observe or check the following points for this: 1. Seals at the central connector must all be present and correctly fitted (Picture_02). 2. The new transparent diaphragm must be correctly bonded (Picture_03). 3. Check headlamp housing for any external damage.
- 11007753Complaint Headlamp or front fog lamp leaky or fogged Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. Headlamps comply with all applicable standards. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps and LED rear lamps: 1. Drive vehicle into workshop (temperature higher than +18 C/+64.4 F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in the formation of condensation, check the headlamp for a defect. (See Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Remedy 2 A Damaged headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness in accordance with LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. Open ventilation system: LI82.10-P-064766. Closed ventilation system LI82.10-P-078304
- 11005294Complaint Rear lamps fogged up/not leaktight. Cause Fogging of the rear lamps is a natural phenomenon, which can occur under certain climatic conditions. This does not lead to any technical impairment of the rear lamps. Remedy Rear lamp: Remedy 1: Clearing fogged/condensed rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 C/+64.4 F) Note: Do not wash the vehicle or subject it to high-pressure cleaning before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the trunk. 4. Switch on the exterior lighting. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation -> a significant reduction in the formation of condensation must be clearly recognizable (defogging progress).
