BMW knows there is a problem with the 2013 x3 timing chain. I have continuously had my BMW serviced at there shops. Never once when my car was in for service did they mention the issue or proactively check. My vehicle now has the issue per the dealership snd indicated it is approximately a 20k repair which they included a new engine. I also followed BMWs recommendation to have the oil changed 1year or when miles were hit per their change program. Just has the oil changed in November and at the end of December now timing chain issues. Again multiple times this issue could have been identified and proactively fixed while under warrenty. Also has issues where the material on the glove box peeled off. BMW is also aware of this issue. Poor design and quality on these models/engine. Thank goodness i was not on the expressway when drivabilty issuev occurred!!!

I am submitting this report to highlight a serious safety defect involving premature timing chain failures in BMW vehicles. The case relates to a 2013 BMW X3, but the problem is widely documented across multiple BMW models from this production era. The timing chain is intended to last the lifetime of the engine. If it stretches, loosens, or fails, the engine can shut down immediately, causing sudden loss of power steering, power brakes, and overall control of the vehicle. This creates an extreme risk of accidents at highway speeds or in traffic. Unlike tires or brakes, this is not a normal wear component and should not fail under ordinary driving conditions. In this vehicle, the timing chain issue was identified at under 72,000 miles. A timing chain should last well over 400,000 miles under normal operation. The premature failure reflects a design flaw, not normal aging or maintenance. The vehicle had recently undergone major servicing at a BMW authorized dealer. At that time, the timing belt and other components were replaced at significant cost. The dealership did not disclose any timing chain concerns during that service. Only shortly afterward, during a recall-related visit, did they report that the timing chain required replacement, with a repair estimate of several thousand dollars. This matter was raised with BMW of North America, including a direct letter to its CEO. BMW acknowledged receipt but declined to take responsibility, treating the matter as outside warranty coverage rather than as a safety defect. The timing chain issue is widely reported, and BMW is aware of it. The sudden engine failure that can result from this defect presents a major safety hazard that warrants NHTSA’s attention.

The component/systems affects is VANOS, exhaust: control error, camshaft is stuck; Boost pressure control: shutdown as a follow-up reaction. This is available for inspection upon request. My safety and the safety of others are at risk because the VANOS assembly (engine) bolts may, over time, loosen, and eventually break. If this occurs, a reduced engine power “safe mode” may be activated. In some cases, the engine may not be able to be restarted after switching off and, in rare cases, the engine could stall which could increase the risk of a crash. This problem has been confirmed by two BMW dealerships. After multiple visits and thousands of dollars spent on attempts at repair, the problem still exists. The resolution offered was to purchase another vehicle or spend thousands more at another attempt to remedy this problem. Although, it is my understanding that there is an open recall for this part (VANOS solenoid). The drivetrain malfunction warning appears and this problem began in July 2022.

I did have the codes read, but nothing showed up. There were no warning indicators. At first I thought it was a driver error on my part, but after a great deal of thought and internet searching, I believe this to be car issue. I do have the surveillance security camera video from the gas station.

On July 15, 2022, my 2013 BMW X3 i28 broke down on the NYS Thruway; I reside in Fort Lauderdale; I've owned the Vehicle for a year and a half, have serviced it at BMW of Fort Lauderdale, and actually had it In to change a lightbulb and make sure all was good. It was towed to Towne BMW in Williamsville, NY, as I was in town visiting family. I purchased the car from Carvana in November 2020; the extended warranty was only effective for a year, and I was shopping for a new one. My Vehicle looks brand new; its garage is stored and well maintained per manufacturer recommendations. The Vehicle only just hit 70,383 miles, since I transport it on the autotrain when I head north for a few months. Towne BMW said they found the problem it was the battery, I pay the $685.78, plus the $300 in towing charges I made it across the street from the service center, and it stopped again I am still trying to figure out how a vehicle that was in excellent condition the day before is now dead? My Vehicle is sitting in my sister's driveway just outside of Buffalo NY with a dead engine. I have a rare genetic syndrome so trying to do everything is killing me; I almost had a heart attack from this ordeal. I still owe on the Vehicle. I contacted BMW of NA; This 2013 X3 come to find out was the worst year yet. There was a class action filed against them, which has expired, Currently this year alone there are an additional 134 vehicles I was able to find on the web, yet we all experienced just the same and in the end a dead engine. When I contacted BMW NA told him the situation, and he gave me a runaround; oh I'll contact the dealership and find the reason, and maybe out of good faith we can provide you with a new engine; I have all his crap emails trying to stall for as long as he could. Towne BMW won't even return my calls, I asked them for a list of the diagnostics they completed, and I received nothing. I had to tow the Vehicle to a german specialis so they could tell me the engine was seize

My wife was driving the car (her main, work car) with our 13 year old. She called me upset and told me that the car would barely move. This was disturbing. She was in heavy traffic. Also the car has been mostly reliable and we only have above 120k on the vehicle after almost 10 years. My wife slowly made it down busy Stocton Blvd. A few hundred feet and safely made it to a business parking lot. I came ASAP. (20min later). There was a message from the car - "Drive Train malfunction " it looked very serious. (Note: My wife is about the best, skillful and careful driver I know. Especially for a person originally from foreign country (China). I gave my wife and child my car and took over the situation. The car would only putt along at 5 mph. So with my emergency flashers on I drove it all the way home using the shoulder. Its about 5 miles home, (more or less). It was pretty crazy situation with how fast people drive on 65th Street expressway. This was my fastest route and only option. Before this a Firestone happened to be just across the street where my wife had parked it so I ask if they could help. "Not today" was their answer. I called BMW of Elk Grove, Ca. where we have always have taken it. Monica at BMW told me it sounded like a recall that had been happening. This was relieving since we haven't been financially well off. It was already 4-5pm so that's why I made the decision to try to make it home. At home I could get my affairs (phone) numbers in order and call for a tow in a much safer place. The unsafest part was getting the dangerous 5-10 miles home. It was Sunday but Monica at BMW said "no problem " just drop it off and they would look at it Monday morning. BMW is telling me over $1800 just to inspect. Not to mention how much for a new timing chain. Monica didn't tell me how much that us. I since looked it up. That's when I saw several similar stories of 2013 X3's which seems much more than coincidence so I'm writing you. Thank you for the opportunity

2EA21002 · 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.

Air Bags:frontal:driver 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.

PE13030 · Loss Of Power Assist Braking
Opened Sep 6, 2013 · Closed Oct 25, 2013
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist:vacuum
In a letter dated September 26, 2013, BMW Group submitted a safety recall notice to NHTSA identifying a defect condition in the vacuum pump oil supply that may result in loss of power assist braking in 76,191 model year (MY) 2012 through 2014 BMW 3-Series, 5-Series, X1 SAV, X3 SAV, and Z4 vehicles equipped with 4-cylinder engines (NHTSA Recall 13V-454).According to BMW, movement of the seal disk within the camshaft may result in blocking of the oil supply to the vacuum pump, resulting in improper pump operation and loss of power assist braking.On July 11, 2013, BMW initiated a change to the camshaft geometry that prevented the seal disk from blocking the oil port.BMW has not received any braking complaints related to loss of power assist after the design change was implemented in production.The owners of all affected vehicles will be contacted by mail and asked to take their vehicle to a BMW dealer who will install a locking ring into the camshaft to keep the seal disk in its proper location.BMW expects to begin dealer and owner notification in November 2013 and complete dealer and owner notification in December when the remedy is expected to be available.Based on the actions taken by BMW, this investigation is closed.
