Specific symptoms reported on the 2017 BMW 430I
Recalls 2
Air bags
- What is wrong
- BMW of North America, LLC (BMW) is recalling certain 2017 430i, 430i xDrive, 440i, 440i xDrive and M4 vehicles and Rolls-Royce Dawn vehicles. The affected vehicles have seat-mounted side air bag inflator initiators that may fail to ignite during a crash.
- Risk
- If the air bag inflator initiator fails to ignite, the seat-mounted air bag will not deploy, increasing the risk of injury.
- Remedy
- BMW will notify owners, and dealers will replace the air bag modules, free of charge. The recall began April 17, 2017. Owners may contact BMW customer service at 1‑800‑525‑7417.

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 BMW 430I owners say
Most recent owner complaints, unedited.
Plastic oil filter housing part cracked and leaked all my anti freeze out on I 95. This incident caused me to have my car towed 3 times to various dealer and shops for repair. Total cost of this repair was approximately 2K with parts and labor + 300. for towing. No warning from BMW - this could have caused myself and others great harm out there on 95 and if I had to drive farther to find a safe place to pull over it would have destroyed my engine.
The contact owns a 2017 BMW 430I. The contact stated that while driving at an undisclosed speed, the temperature gauge indicated that the engine was overheating, prompting the contact to discontinue driving the vehicle. After a visual inspection of the engine compartment, the contact observed that the coolant reservoir was empty, even though it had been refilled two weeks prior. The low coolant warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the federal safety agency Hotline for assistance. The failure mileage was 123,000.
The car is sporadically saying passenger restraint system, going on and off.

In addition, the contact stated there was an abnormal sound coming from the engine. The vehicle was restarted; however, the failure recurred. The vehicle was taken to the dealer. However, no cause for the failure was found. The contact stated there was an abnormal fuel burning odor entering the interior of the vehicle. The contact checked under the hood and noticed an oil leak outside the engine. The "Low Oil" warning light illuminated, even though the oil level on the instrument panel showed the level was normal. The contact added oil. However, no cause for the failure was found. The contact had placed a small cigarette butt by the engine and when the contact picked up the vehicle, the cigarette butt was still in the same place he had placed it. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The contact stated that the failure persisted.

The contact owns a 2017 BMW 430i. The contact stated that while operating the vehicle, the message "Coolant Leak, Refill Coolant" was displayed. The vehicle was taken to the local dealer who diagnosed that the thermostat, oil filter housing, upper radiator hose, front engine block plug, water pump, turbo coolant line, and gasket were faulty and needed to be replaced. The contact stated that the oil filter housing and gasket were previously replaced. The vehicle was not yet repaired. The manufacturer was contacted but no assistance was offered. The failure mileage was 150,000.
Catastrophic failure of plastic oil filter housing causing complete emptying of engine coolant. Failed part is available for analysis. Car was immediately immobilized, requiring a tow. This problem was confirmed and ultimately repaired by local BMW dealer. No other inspection has occurred but issue seems very prevalent based on online searches. No warning before failure occurred.
There is a recall on the connector for the year of my vehicle and the BMW Sewell Plano dealership is trying to charge me for the service and repairs. They will not honor the recall.
Electric Water Pump and connector broken. Vehicle overheating and causes a fire risk to driver and others. Problem has been confirmed by dealer as well as multiple independent service centers. Have not contacted insurance company but will do so, if advised. Only warning was low coolant light on the dashboard.
