• Pedestrian alert sounds investigation # DP22005

  Nhtsa received a petition on or about july 18, 2022, requesting that federal motor vehicle safety standard (fmvss) 141 be applied to all electric and hybrid vehicles operating in the united states. The petition can be reviewed at nhtsa.Gov under odi number 11486072.Fmvss 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 kg or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after march 1, 2021.The petitioner asserts that hybrid and electric vehicles to which the standard does not apply should be found to contain a safety defect. In support of the petition, the petitioner includes findings contained in a bill introduced in the house of representatives in 2009, the pedestrian safety enhancement act of 2009, h.R. 734, 111th cong. (2009). A related bill, the pedestrian safety enhancement act of 2010, became law in january 2011 (pub. L. 111-373). The petitioner requests that nhtsa require all electric and hybrid vehicles comply with fmvss 141, regardless of production date.The defect petition has been opened to evaluate the issue and determine whether to grant or deny the petition.The associated product list is not exhaustive and may contain vehicles that are equipped with pedestrian alert sounds.

• Desiccated air bag inflator rupture investigation # EA21002

  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.

This mb model has an electric motor that fails at around 35000 to 40000 miles, and makes the vehicle to stop suddenly causing serious risks to the driver if this happens in any main highway. Two weeks ago my wife was driving northbound at the fast lane of the palmetto expressway , in miami fl, when the car stopped giving no time to avoid coming traffic. Fortunately one fdot ranger was driving same way and protect my wife turning on its emergency lights while they wait for a tow truck to arrive. This model of mb is assembled with a tesla motor that has been proven to fail, but tesla has taken fast action to avoid inconveniences to its customers. Mb has doing nothing to advice its customers on this critical issue, putting on risk on a daily basis all drivers that ride tis mb model. I figure if others are facing similar issues, it would be good to get a recall set up if mb does not step up to the plate. It took four years for these issues to show up near the end of my warranty, and since the cars remain essentially the same through the 2017 models, we may expect to see others model years show the same issues as the end of their warranties come up. I hope not, for everyone else but best be prepared. My vehicle can been inspected at the mercedes benz of miami dealer where repair are underway.

Car stalled while going on expressway at 30 mph. Complete loss of power. Had to pull over and power off the car. Restart of the car after a while and everything was back to normal.

Car was stopped and the engine turned itself off. Restarted manually. Took the car to the dealer for reprogramming. Did the same thing again.

While the car was in motion, the engine has switches off and the car goes in neutral. This has happened already 3 times (approximately once per month). It has happened while on the interstate, while driving on a small road, and while approaching a stop sign. The car can be restarted normally. We have had the car at the mercedes dealer in september 2015, and the tried to fix the problem by installing the latest software. However, it just happened again. This car is not safe to drive the last time the car stalled while driving, we let the car come to a complete stop, without touching anything but the break, and make a picture of the instrument panel. This picture is attached to the report to document the incidence.

On 10-5-15, my 2015 mercedes b class with 3300 miles decided to lose all power in the middle of 101 in rush hour traffic. Luckily traffic was moving at 15mph, i had to completely stop the car in the middle lane. Put the car in park, shut it off and restart to regain power. There were no check engine light or signs that the car was broken, i just simply lost all drive power even though i was in d. It was scary as i was on the 101 at about 4pm. This also happened at another when i first got the car, please get mercedes to fix this before i get rear-ended and crushed.

Driving on the freeway at 65mph, experienced complete and sudden loss of drive/power. Car charge was around 1/2 full. Had to pull to the shoulder as the car rolled to a complete stop. Finding lots of other reports online, dealer has been unable to determine the root cause after 1 week. Dealer reported other similar incidents from other drivers.

3xs i have had the car stop working while driving. All three occasions while coming to a quick stop the car quit working. I had to come to a complete stop, put the car in park and restart the vehicle. I leased the car in july/august 2015, last incident was on 9/22.
