The model/year Mercedes-Benz are well known for experiencing this/these particular issues. My research has shown that these year/make/model vehicles are experiencing the same type of mechanical failures nationwide. The issues all relatively begin around 75,000 miles. I've only had my car 3 years putting 30000 on it hardly driven/cared for **Issue Found:** Oil was leaking onto the ignition coil and spark plug of cylinder 3. **Source of Leak:** Valve cover gasket failure. **Recommended Repairs:** - Replace the valve cover gasket (to halt the oil leak). - Replace spark plugs and ignition coil (which were contaminated/damaged by oil). **Relevance to Warranty:** The valve cover gasket is only covered if it fails as a result of an internally lubricated engine part causing damage. Ignition coils and spark plugs are maintenance items and are not covered by warranty plans. **Required Repairs (Identified Mechanical Issues)** - **Coolant Pipe Leak – $850** **Issue:** Coolant leaking from a pipe on the side of the cylinder head. **Relevance to Warranty:** Typically not covered unless it pertains to a failure in a covered system such as the water pump or cylinder head due to an internal breakdown. This is likely classified as an external plumbing component, which is not included. - **Oil Feed Line Leak – $600** **Issue:** Oil leaking from the side of the engine, traced back to the oil feed line. **Relevance to Warranty:** This is not typically covered unless the oil feed line is part of the oil pump system and has failed due to an internal issue (usually regarded as an external line). **Other Items Found (Worsening Issues)** - **Timing Chain Rattle / Cam Adjuster Noise – $6,000** -**Issue:** Rattling sound during startup. **Diagnosis:** Noise emanating from the timing chain and camshaft adjusters. **Relevance to Warranty:** This is covered under Secure Plus, as both the timing chain and camshaft adjusters are recognized as internally lubricated par

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

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.
