I purchased this as a used car online and had it delivered to me. It hasn’t been a year of owning it yet and my car is now un-drivable. I was driving down the road and my transmission malf light came in and my car went into limp mode. I had to get it towed and the local shop who has it said it’s a broken timing chain from a failure. I’ve never had any issues and then all of a sudden now I have an estimate of $3627 to be able to drive my car. Upon researching, my model/year has a known issue for this happening. I feel stuck and don’t know what to do but feel like I need help so I can get my car back running. It barely has 105k miles on it. The dealership I purchased it from never mentioned any known issues with it.

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

I have a 2013 BMW X3 i28 4-cylinder turbo with 70 383 miles. I have maintained it regularly through my BMW service center here in Ft. Lauderdale, FL. I was away and had my car since I brought it north on the auto train to save wear and tear and mileage. Unfortunately, on July 14th, I was headed from Buffalo, NY, to Rhode Island on the NYS thruway when my engine died on me; thank god I could get it to a shoulder, or I would have been dead, seeing there were a few semis behind me. I called a tow truck a nightmare since tow companies have a monopoly on towing off state thruways. It was towed to Towne BMW in Williamsville, NY, They did a diagnostic, and it was only the battery, so they said. So I went and returned my rental car and paid my bill, the time was now 6:00 pm, and I was good to go, so they said I didn't even make it across the street, and the engine did the same thing. This time they tell me my engine has seized up, and oh well, too bad, not their problem. They never gave me a diagnosis of what was completed on both days, and they continued to make a new narrative on the issue. In both instances, a light that said turn the engine off appeared after the engine shut down. I have contacted BMW North America, but they haven't done anything. Best, PH

We dropped our BMW X-3 on April 11, 2022, to get checked out, due to a continued check engine light. We had dropped it a few weeks prior because of the same issue. We thought they had corrected the problem as the check engine light was no longer on after the first time we received it back. The car stalled a couple of times at the stop light when accelerating. They have done extensive work, they said, in trying to analyze the problem. They are trying to force us to bring the loner back and take our car back unfixed. They have exhausted the third party warranty money because they went down the wrong rabbit hole. The warranty company obviously doesn't want them tearing apart the engine and going in another direction because Rockvile BMW has already had the car so long they could have rebuilt the whole vehicle from scratch. It doesn't make sense for us to tell them to go ahead and spend our money either as they obviously don't know what they are doing. I called BMW headquarters in NJ. The gentleman there suggested I ask them to call the regional dedicated group of service engineers to help with the problem. He also suggested that if they have gone that route that I escalate the problem to the general manager of Rockville BMW. I called the dealership and spoke to William Rodriguez, the service assistant who had been keeping us abreast of what was being done to our vehicle. He said they had designated regional service engineer come over and look at the vehicle, and that person also had no luck with the fix. William said there was nothing else that they could do.

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.

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: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.

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.
