Strong fuel smell in the cabin when I start the car in the morning. I'm seeing this as a common issue in threads online. Car out of warranty so need help making this a recall item given the danger of fuel leaks. Solutions posted are below: 1) quote from my invoice: confirmed fuel leak was coming from line to high pressure pump. Removed lower panel of transmission to gain access to lines. Removed high pressure fuel pump covers, removed and installed fuel lines, and installed in reverse order to correct. Ran engine to verify no large fuel leaks. Found good at this time. 2) have your dealer replace the two flexible fuel lines from the fuel feed line to the high pressure fuel pump.there is no official bulletin on this but this is the fix.

Defect investigations
Desiccated Air Bag Inflator Rupture
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 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 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

What 2017 Mercedes-Benz E350 owners say
Most recent owner complaints, unedited.
I am in an mbfourm and I am starting to hear of engine failure at an early age. I have not experienced this, yet. But, from what I am reading in the forums, a lot of people with the same model engine I have in my 2017 mercedes e300 are having issues where the piston cracks and they need a new engine. Mercedes isn't paying for engine replacements and it is all out of pocket cost. I am worried that once my warranty is over and my engine blows because of mercedes designs flaw, I will end up spending 9-10k for a new engine because of a design flaw. Here is the link to the forum: https://mbworld.org/forums/e-class-w213/798120-2018-mercedes-w213-e300-needs-new-engine-23k-miles.html https://mbworld.org/forums/c-class-w205/731642-w205-c300-stay-away-piston-cracked-65-k-miles.html
On sunday 9/13 driving at 55 MPH on the highway I heard what sounded like a gunshot and then glass just fell on me from everywhere causing me to swerve all over the road and I thought it had to be something I fell off the 18 wheeler tractor trailer near me and I chased him down and he almost ran me off the road and killed me we got into an altercation only to find out is a defect from mercedes. If someone could please call me [xxx]or email me at [xxx]. Thank you information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
At around 2.15 pm cst, I was driving my mercedes westbound on I-694 towards minneapolis at roughly 70 MPH when suddenly my e300 stalled and by the time I could figure what was wrong, I lost all power in the steering wheel. The mercedes brake assist triggered a hard brake and my car stopped in the middle lane on the freeway. The car behind me nearly missed me and at this point every light in the dashboard lit up (I have attached the picture below). I tried hitting on the ignition multiple times but got no response. At this point, I decided not to sit in the car since it was too dangerous with fast oncoming traffic and it was only going to be a matter of time that someone would rear end me. I stepped out of my car and while multiple cars were approaching me at high speed from both left and right lanes I found a very small window of time (2-3 seconds) to sprint from the middle lane of I-694 to the shoulder. My worry was still far from over as my car was still sitting in middle of the interstate and now I was concerned about the safety of other folks who were traveling in my direction. I saw 12 to 15 cars almost rear end my car. While this was happening, I realized my phone was dead and I was unable to call 911. I continually waved at the oncoming traffic to alert them of my car and requested them to call 911. About 7 to 9 minutes later, the state highway patrol showed up and blocked traffic to assist me with moving my car to the shoulder. These 7 to 9 minutes were the most traumatic I have ever seen in my life. I felt helpless, anxious, and extremely stressed out.
Car shimmering above 5/60 MPH. After many visits I was charged $839.39 to replace the rotors. Contacted mb customer service and they said there was nothing they could do for me but to document my issue. Mb factory would need to issue a recall.I explained that there a a lot of other customers around the world on a mb forum and they sait they would need to report the issue as well problem persist and I was told it was the tires I purchased from costco. Returned the tires to costco and purchased 4 new tires on 12/30/19 and issue still persist
When starting the car, in the first 20 minuets the car has a very strong fuel odor in the cabin causing difficulty breathing and eye irritation, I need to leave the car running for 20 minutes with the windows open before I can get in and drive, I went to the dealer and was dismissed as if everything is good, I don't know what to do next.
Car caught fire spontaneously while parked. A total loss.
