Electrical system
The EIS module we have found has an issue with the part from Japan that does not have enough Sauder on a part of it, so when the temp drops below 50 degrees or less the ignition starts but all the safety features go off and the computer shuts down the vehicle. Reason is the metal contracts in cold weather causing the connections to not fully meet. We have figured this out after many times of replacing the main battery, aux battery thinking this is the issue. After much research on the web and MB forums this seems to be an issue especially in the colder climates with some of the older models. Some others have had have their autos stop in the middle of driving them in cold weather. Not sure…

NHTSA defect investigations

Desiccated Air Bag Inflator RuptureOpen
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…
