  Fuel line leak: the temperature in s. Florida hit a low of 45 degrees tonight on 1 dec 2020, first noting the issue described. Upon return home from an 8 mile total trip to the store, my daughters exited the vehicle and noted a strong gasoline odor. Upon investigation myself, I found gasoline pooling behind the engine where the main fuel line connects to a rubber hose. The pooling was on the rear of the undercarriage cover as also described below. similar case found online: https://www.benzworld.org/threads/gasoline-leak.2936569/ "there IS a fuel leak where the steel line from the tank connects to a rubber hose near the firewall. There IS apparently a revised fuel line connector available, no recall as yet. This joint IS apparently part of the low-pressure fuel system (4 bar), not the high-pressure side (200 bar)."

  Since the lease purchase in 2017. the glc300 has been in service on a quarterly bases for the brakes (constant squeaking making feel unsafe) and now a constant check engine light. this IS the 4TH vehicle I lease and by far the worst. I contacted mercedes USA asking them for a replacement vehicle. I was willing to accept a used or loaner car but the only thing they offered was $1000 towards my next vehicle. as of today, the vehicle IS back in service for the 7TH or 8TH time. I am hoping someone can help or at least prevent this from happening to someone. I have attached all paperwork for your review. thank you

  We were driving down the freeway, traveling approximately 65 mph in oakland, ca. The weather was clear - no rain and approximately 60 degrees. All of a sudden, there was a loud noise like a gunshot and our panaramic sunroof shattered. At the time, we had a cargo box on top of the car (on a frame that was not touching the sunroof) so it IS unlikely any projectile could have hit the car. The cargo box was still affixed to the car and secure after the incident. It was not an extreme temperature, nor was there any extreme weather (rain, snow, hail) at the time. There were no underpasses nearby. Most of the glass was caught by the sunshade, but if we had the sunshade open, the glass would have entered the passenger compartment. We have owned the car approximately two weeks at this time.

  I was driving straight toward highway 287 at 65M speed, there was no snow no rain normal traffic no cars close to me, all the sudden esp indicator went off, accident collision prevention indicator went off on my dashboard and the vehicle speed went down to 30M, 20M and I was not able to bring the speed back, the vehicle stopped responding. I pulled over called road assistance, I turned the engine off, start again I was able to drive at 20 - 30mile, when I entered highway 46 on the traffic light the vehicle was not responding at all, I kept pressing the gas pedal, until the car start to drive again up to 25M. Took it to the dealership workshop, they was faults in the sensor and gas pedal they fixed.. I took the vehicle after one week check engine indicator went off again. Took it again to the dealership workshop. I consider what happened with this vehicle IS real safety issue where all the sudden you can't control the speed anytime anywhere.

  Refer to 2016 glc-300 complaints about screeching service brakes and copy/paste complaints here. 2017 model has the same screeching noises and car was purchased in august 2016. Going slowly in reverse or forward from cold start will cause loud screeching noises. my neighbors have confronted me about the car noises. It's absurd that the documented issues from the 2016 model continues in the 2017 model. Dealers are aware and have said applying brake paste does not help. A larger fix IS still in the works. The noise IS also making us attempt to back out of the driveway with as little braking as possible. After driving a few miles the screeching will mostly stop. There have been other occasions when it has not--likely due to wet or cold weather conditions. as of 12/29/2016, dealer IS saying a new fix may be coming 1/5/2017. I am hopeful but weary and will proceed with lemon law protocols. *tr

• 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.

  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.

Cause Until now the rear axle shock absorber support bushing was only available together with the rear axle shock absorber as a replacement part. In future, the rear axle shock absorber support bushing will be available individually as a replacement part to avoid any unnecessary shock absorber noise. Remedy For noise problems on the rear axle shock absorbers, please always make a noise diagnosis, for example using Chassis Ear to localize any sources of noise on shock absorbers or support bushings. If the noise originates from the upper part of the shock absorbers, it is enough to replace the support bushings. Otherwise the complete shock absorber including support bushing have to be replaced. The modified support bushings must be replaced in pairs the first time so that any mixed installation of old and new is reliably ruled out.
• 10214958Complaint 1. Vibrations noticeable at steering wheel when front axle is excited when driving at a speed between 65 km/h and 130 km/h over an obstacle.

Cause The XENTRY battery tester uses the stored on-board electrical system data in the SAM module to access the health of the 12 volt battery. The XENTRY battery test may not take into account a single discharge event because the SAM cannot record the data if the battery is discharged. Note: A discharged battery does not necessarily need to be replaced. A discharged battery may be recovered with no permanent damage. Remedy Follow guided tests as described.
• 10209874Mercedes-Benz AG (MBAG), the manufacturer of Mercedes-Benz, has determined that on certain MY 2015-2018 C-Class and GLC-Class (205 and 253 platform) vehicles, the software for the powertrain control unit may not correspond to the current production specifications. It is possible that the next maintenance interval is displayed to the user as a negative distance reading in the instrument cluster. What Were Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the powertrain control unit software.
• 10207199Complaint The range of the integrated garage door opener (GTO) is too short. Cause 1. Vehicles equipped with infrared windows and/or a heated windshield may suffer from complaints involving low transmission power. 2. When comparing the range between the integrated GTO and the garage door hand transmitter, the garage door hand transmitter is tested outside the vehicle. 3. The garage door hand transmitter is being aimed towards the garage door, but the vehicle is in a different position. 4. The garage door drive is old. Remedy 1. The lower level of transmission power is mainly perceived by customers who did not have any infrared windows (code 595) or all-round infrared windows (code 596) or heated windshield (code 597) in their previous model or who have another model without this special equipment in their fleet. The loss in transmission has technical reasons, i.e. a thin metal film is fitted in the windows. Please consider these codes and advise the customer accordingly! Replacing parts does not remedy the problem. 2. Perform the comparison test between the integrated GDO and the garage door hand transmitter under identical conditions. The garage door hand transmitter must be inside the vehicle and must be held at the height of the inside rearview mirror. 3. The customer instinctively aims the garage door hand transmitter towards the door. However, the transmission direction of the integrated GDO depends on the position of the inside rearview mirror, and thus depends directly on the position of the vehicle relative to the receiving antenna of the garage door drive.
• 10207198Complaint The garage door hand transmitter cannot be initialized with the integrated garage door opener in the inside rearview mirror. Cause 1. The integrated garage door opener (GDO) is not compatible with the opening system installed in the garage. 2. The garage door drive uses a rolling code system. In contrast to the fixed code system, the LED in the mirror in this case flashes green after programming. 3. When the handheld remote control is initialized with the integrated GDO, the distance between the handheld remote control and the GDO is too long or too short. 4. The maximum programming time of the hand transmitter was exceeded. The hand transmitter switches itself off after 10s to 20s. However, the garage door opener needs up to 30s to learn the code. 5. The maximum programming time of the integrated GDO was exceeded. The integrated GDO has aborted programming unsuccessfully. 6. The GDO cannot be programmed after replacement (See #9). 7. The batteries of the hand transmitter are too weak. 8. A part of the signal was not registered correctly. 9. The GDO is not programmed to US standards. 10. Errors with Chamberlin MyQ, Liftmaster MyQ, or Craftsman AssureLink systems causing loss of synchronization. Remedy Note: The numbering of the remedies refers to the numbering of the causes. 1. Installation of a universal receiver. Order via the Homelink Hotline. 2. In the case of garage door drives with rolling code system, synchronization of the garage door drive must also be performed. 3. Keep the correct distance when initializing! This can vary between 5 and 20 cm depending on the system. If the initialization attempt is unsuccessful, repeat the initialization process, changing the distance between the hand transmitter and the mirror.
