  Left side boost tube blown twice on my vehicle. Technical part info: 204-528-00-00, Charge Air Hose Both incidents involved sudden loss of power in the middle of the free way driving. First incident: Christmas Day 2018, on the way to Las Vegas from Grand Canyon visit, on highway 93. Fortunately, no vehicle was behind when I lost the power, moved to right lane and continued driving slowly to reach the hotel in LV (about 50 miles at low speeds). Check engine light came on immediately after loosing the power. Next day morning, visited the local Mercedes dealer to repair the vehicle, it costed me $520.19 This was in the middle of a long road trip from Phoenix to San Fransisco. Second incident: July 29th 2021, right after I picked up the vehicle from a repair shop to repair the rear bumper. Vehicle pick up was slow, no check engine light. Next day morning, on the way to work on I-17, vehicle lost the power while merging onto Freeway. Almost got hit a by trailer truck which was right behind me. Moved back to right lane and slowly drove to work. Check engine light came on after few minutes of driving. Took the vehicle to repair on August 6th to a local dealer. This time they didn't charge me for the repair and said it's covered under warranty. I don't have any warranty. Seems like it's a design issue with turbo charge air hose and/or a faulty part. It's a real safety issue if it blown in the middle of driving.

Safety risk according to takata, in the event of an inflator explosion, metal fragments could pass through the air bag cushion material, which may result in injury or death to vehicle occupants. Remedy: an authorized mercedes-benz dealer will replace the passenger-side airbag. I have been asking about a repair part for over a year and a half with no luck. After actually reading the safety risk, my wife IS afraid to drive the car especially with our son in it. I now have a car sitting in my garage that we dont feel safe driving based on the verbiage and seriousness of the recall. Mercedes benz should be responsible and deliver a solution in a reasonable amount of time. With an active recall of this caliber there IS nothing I can do with the car but just garage and that seems very unfair. Either fix the issue or repurchase the vehicle.

  My 2014 mercedes glk 250 with 16,705 miles, on 11/03/2015 experienced the engine warning display stating to add blue. I did this but the warning did not remove but stated I had 10 starts remaining. I was 700 miles from home so returned conserving my remaining starts. found multiple problems with the blue tech emissions system including def injector nozzle failing to spray. all covered by warranty. on 06/15/2019 with 58,129 miles, the engine warning light again came on to add blue. I checked bluetec level to be nearly full. the warning stated I had eight remaining starts. being 700 miles from home, I returned. Having three remaining starts.i took the vehicle in for immediate repair. Found nox sensor 2 faulty and was replaced. on 6/28/2019 with 58,126 miles, the add blue warning again appeared. the bluedef warning only 10 starts remains. the nearest merecedes dealer was in denver being 173 miles away. I took it there where they replaced def module, the preheater and tank temp amoung other faults. on 7/15/2019, with approx. 58,300 miles, the same warning appeared. returned to the same denver dealer who then replaced the nox sensors in the emission system. I was informed that the frequency of repair for this model IS very high and expensive (my last totaled $5,000). this vehicle IS totally unreliable and should have been recalled. because of the emmision system utilized, numberous other problems occur such as the complete windshield washer system was replaceddue to the extreme heat created by the system. same with oil leaks, etc.. mercedes could have at a minimum extended their skimpy warranty of 50,000 miles but they refuse to acknowledge any fault claiming "the best or nothing"! this model IS definitely nothing!

  Blue tec system for diesel fuel emissions in my 2014 mercedes benz glk250 model IS inherently flawed with repeated failures that cause the car to "go limp" (unable to start after 10 or less starts when there IS a failure in the blue tec system.) as a result, the car IS not only unreliable, it IS unsafe should the car "go limp" when needed for emergency or on a road trip or unable to drive out of an unsafe area, etc., since only a mercedes benz dealer can re-set the system after repairs so that the car will start again. to date (5/16/19) my 2014 glk250 has 28,388 miles and has been returned to the dealer 6 times (first time, dec. 6, 2014 and 5 more times since) due to the electronic warning message "10 remaining starts/add blue" which has always turned out to be an electronic failure in the blue tec system. The message may appear when the car IS parked and the ignition IS turned on or while driving. Sometimes, the check engine light may first appear followed by the "remaining starts" message a few days later. There IS no logic or set sequence. And when it appears, there IS no alternative but to immediately go to the dealer for repairs and to re-set the computer so the count down stops and the car can be started. The reason this IS not a widely known problem IS that there were not many glk 250 blue tec cars sold in the u.s. And mercedes benz no longer builds this model and has stopped offering diesel passenger cars in the u.s.

  "Spontaneous sunroof explosion" - my 2013 mercedes glk250 bluetec experienced a spontaneous sunroof explosion while driving on the highway at highway speeds. An accident nearly occurred as a result of the gunshot like impact experienced inside the cabin of the vehicle as a result of the sunroof explosion. I had several chards of glass embed in my skin and in my eye, as the explosion produced an ultra fine dust of safety glass particles that were unavoidable. No impact debris or foreign object was attributable to the cause of the explosion, hinting at manufacturer defect.

• Desiccated Air Bag Inflator Rupture

  EA21002Opened Sep 17, 2021Open
  From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant…

  From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

• 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.
• 11008091Complaint During a phone call, the called party has difficulty understanding/cannot understand the driver, or interference/background noises are audible to the called party during a call.

• 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
• 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).
