April 22, 2021 (87181 Odometer Out) Virginia Inspection. Passed. Recommended replacement of front rotors and brake pads. July 22, 2021 (87989 Odometer Out) Oil Change, tune up if needed, front rotors and brake pads replaced. Did not reset vehicle computer: hood light as well as brake light came on over the next week. August 5, 2021 Brought back to repair shop. Computer reset (88148 Odometer Out). Aug 13, 2021 Driving approx 45 miles per hour when the engine cut out, I narrowly pulled over but not quite out of the road--error message: Drivetrain Malfunction, "Drive Moderately. Maximum drivetrain out put not available. Consult Service Center." Dangerous section of road, traffic, extremely hot and humid, with thunder storms. Turned the car off and tried to start, error message flashed, "No service since 2015." Towed first to repair station who performed the recent maintenance on the vehicle. They did not look at the vehicle until several days later. When they did, they informed it was the camshaft position sensor. And further, that the sensor would have to be replaced (@$700) so that the car could start and then they would recheck for the problem. Without a car for several weeks. August 17, 2021 had the car towed to a shop suggested by a neighbor. There, the owner/mechanic stated that he could see glimpses of the "guide" (timing chain), that it was broken and suggested I have it seen by a BMW-specific shop to make the repair. I located a shop in Winchester VA and had it towed there. Confirmed it was the timing chain. 10/19/21 Picked up. Total charge: $3796.19. I found that this was a known issue and the owner confirmed. However, the fix was only extended to 7 years/70K miles. I bought this car from a dealer in 2015. I was never informed of this known issue; not from the Dealer, the service shop, or BMW notification(s) via email or other. The break down and the multiple negative impacts caused could have been avoided.

I was driving on the highway and took my exit and the car suddenly stopped with the message "Drivetrain malfunction. Drive moderately." After this, the car would not move even with the engine on. It was as if the it was stuck in one gear and wouldn't move to "Drive". I turned the car off and back again. At this time, the car started to sputter after it started. Then, I let it stopped the engine for about 20 minutes. When the problem happened, the check engine light came on. After 20 minutes, I started the car again and I was able to drive it and the check engine light went away. However, since I had to go back on the highway, I was concerned about driving as it might stop suddenly on the highway and create a major accident. As per google, this seems to be a common issue with BMW X3's. The company should recall and repair such an incidence from happening.

More frequent drive train errors and loss of power. Cause defective timing chain guide. This seems to be very common on this year and model of BMW speaking with other BMW owners of the same car. Luckily we were not in heavy traffic and could drive to repair shop.

While driving in the southbound fast lane on Highway 101 on July 28, 2021 near Morgan Hill, California, the computer screen advised that there was a fuel supply problem, and at that instant, the engine shut down and the transmission went into park. There was no opportunity to coast onto the shoulder. The vehicle would not restart, nor would it shift out of park. My wife and I were trapped in a vehicle that would not and could not move, in the fast lane of a major California freeway, surrounded by rush hour traffic, with the likelihood that we would be rear ended and perish in a frozen car. The danger was severe. We put the emergency flashers on. Other cars were passing us on the shoulder and on the right hand side, and getting out of the car was dangerous and impossible. We were convinced that we were going to die or be severely injured. We called 911 and at that moment another driver pulled behind us to offer a buffer of safety with his car, until the California Highway Patrol arrived and a tow truck was called. Until the arrival of the tow truck, we remained in severe danger. The tow truck had to pull the vehicle to the shoulder locked in park, causing it to shudder as the rear wheels hopped on the pavement. Eventually we hired a flat bed tow truck to bring the vehicle to our local BMW dealer, and the problem was diagnosed as a faulty fuel pump. Apparently, if your fuel pump fails with this vehicle, you may die. This problem is documented with other drivers at the website carproblemzoo.com/bmwX3/other-fuel-system-pump-problems.php, all of whom were put in peril as a result of this systemic failure. I hope that this notification may save some lives, and would welcome further contact to discuss the matter further. My wife and I still suffer from emotional distress and PTSD, as a direct result of this incident, and will not drive this vehicle again.

The engine failed while driving on the highway on 06/22/2021. My safety was put at risk because the traffic was heavy during the middle of a rain storm on the interstate. Cars had to swerve to avoid me as I was only able to coast my vehicle to the side of the highway. I was almost struck by traffic. A number of warning lights suddenly went off without have gone off before in king and oil pressure message and engine failure message and a transmission failure message all at once. I am in the process of getting the vehicle towed to be inspected. This appears to be a known problem with 2013 BMW X3s according to the research I have done since the incident but BMW won’t issue a recall for the vehicles even though they are aware that this is a dangerous vehicle issue according to websites like bimmerpost,com and car gurus.com which have similar incidents to mine posted on their websites. BMW needs to issue a recall and make the appropriate repairs.

I have been told that the power chain guides have broken and must be replaced. This could cause the power chain to come off mid-drive and completely shut the car down.The cost of parts and labor for repair will be around $3,300. This car isn’t old, is well cared for and maintained and does not have high mileage.

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).

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. 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.

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.
