I am writing to formally document two significant incidents involving the complete failure of the high-pressure fuel system in my BMW vehicle, VIN [XXX] , which have raised concerns about the reliability of this component. On [XXX], while navigating city street traffic, my vehicle, with 57,376 miles, experienced a total loss of power, resulting in the vehicle stalling in the left lane. The vehicle was towed to an authorized BMW dealership, where the entire high-pressure fuel system was diagnosed and replaced under warranty. As the second owner of this vehicle, I acquired it from my neighbor, the original owner. Upon reviewing the complete service records provided by the previous owner, I discovered that a nearly identical issue occurred at 39,066 miles. The service documentation states, "Client reports that while driving, the vehicle lost power and stalled." At that time, the high-pressure fuel system was also fully replaced. Further investigation revealed that BMW issued a safety recall notice between these two incidents, acknowledging potential failures in the high-pressure fuel pumps. However, the recall indicated that no remedy was available at the time. I've attached all the service records for both incidents and BMW North America's letter.

I was driving approximately 30 mph. As I continued to accelerate the fuel system light came on and the car shut off in the road. I had to have it towed to the dealership as it would not start. Gas fumes could also be smelled coming from the car. Once looked at by BMW service center I was told “ EKPS and the fuel pump are intermittently failing. I was able to able to verify the concern briefly. Vehicle may lose fuel pressure randomly. Upon removing rear seats and inspecting harness, I found the wires going into the EKPS to be burnt. The wires from the EKPS to the low pressure fuel pump will also need to be replaced.” I did research and saw that this was recall on other years of this model. Also the middle back seatbelt does not work. Also even after multiple alignments my car still pulls aggressively to the right causing near collisions and off roaring.
Vehicle stopped three times on highway. There is an issue with fuel injection. I am repairing the same thing every year and it is stopping every year on highway. They keep on repairing/replacing the module and I still get the problem. I missed a big rear collision because of this. This model has so many issues. Suspension broke.…

Vehicle stopped three times on highway. There is an issue with fuel injection. I am repairing the same thing every year and it is stopping every year on highway. They keep on repairing/replacing the module and I still get the problem. I missed a big rear collision because of this. This model has so many issues. Suspension broke. So many issues with gas pump. being it a first generation hybrid, it can cause threat to so many people if we let these vehicles be on road.

I brought my 2017 X5 xDrive40e to my local dealer (Ray Catena in White Plains NY) after getting a ‘Drivetrain Malfunction” Error. After several weeks at the dealer, and thousands of dollars in repairs, I’m being told today that: -The car needs a new Electric Drive… cost $12,000 -The replaced electric drive may not solve the issue, which might be the transmission.. replacement cost $16,000 So almost $30k to perhaps solve the issue on a car with a $19,000 value per Kelly Bluebook. And this is a known issue for Hybrid X5s per multiple BMW owner websites.. Here is one: https://g05.bimmerpost.com/forums/showthread.php?t=1887640 My dealer is telling me that the value of this car is currently zero ($0.00) which I find to be absolutely ridiculous.
The vehicle’s gas tank has a leak on top the cabin fills with the smell of gasoline. After a smoke test was done, the test showed a leak coming from the top of the tank between the tank and the inlet for gasoline refill.

Hi, I have bought BMW x5 2017 from certified dealer in Nov 2020. From the beginning, vehicle is giving me problems. I spoke with BMW customer care and they are not helping me much. Below are the problems that vehicle has given me. They are so many other problems but I am noting the major problems. 1. Vibration during acceleration 2. The rear suspension got broke 3. Vehicle stopped on the road while traveling with an infant. Problem they said is fuel is not pumping into engine. They confirmed tank has 3/4th of gas. So that’s the problem with the vehicle. - they left us on the road for 4-5 hours until they tow the car. - my family including 3 months old baby has to get shelter inside a gas station for almost 12 hours until I get a rental car because they didn’t give loaner vehicle or not provided any help to rescue my family to bring to safe location. 4. The air suspension completely broke while traveling from Baton Rouge. Which caused back pain problem to my wife who recently has c-section. I am still dealing with her back pain treatment after that. And they took more than 20 days to repair and give the car back. I got an old Dodge Journey as a loaner from rental agency. Why do I need to pay for luxury car if I have to drive a Dodge Journey. 5. During the problem 3, BMW service center said fuel wasn't pumping into the engine and they said they fixed the issue. Again on August 14th 2022, vehicle was broken due to fuel pumping issue while I was in a city which is 2 hours from where I live. vehicle stopped on highway without any notice. They could have saved me and my family lot of stress and health issues if they supported us well and inspected the vehicle before selling us. They looted our money and played with us emotionally and caused physical and mental damage by doing it. I had to rescue my 3 months old baby because of this vehicle which stopped on high way during hottest season of summer mid June 2021. Your help is much appreciated in this regard.

The contact owns a 2017 BMW X5. The contact received notification of NHTSA Campaign Number: 21V586000 ( FUEL SYSTEM, DIESEL ) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact stated while driving approximately 30 mph when attempting to accelerate the vehicle when the vehicle suddenly lost power and the fuel pump failed. The contact was able to maneuver and coast the vehicle to the side of the road. They then had the vehicle towed to the dealer. The contact stated that when the vehicle was towed they learned that the gear shifter was locked in position. The approximate failure mileage was 29,000.

On July 30, 2021, my 2017 BMW X5 35d, which had only about 49,000 miles on it and which had been serviced only six weeks before, died without warning. My son and I could have been killed. The car went into Park and had to be towed on a flatbed to the dealer. After 5 days of no word, the dealer falsely accused me of putting gasoline in my diesel vehicle. The dealer eventually determined that the high-pressure fuel pump had failed, which caused exactly the problem listed in BMW's July 29, 2021 recall notice to its dealers: it caused metal fragments to contaminate the entire fuel system. BMW initially advised me that it had no "recall remedy," but when it did, it would replace the fuel pump but would not repair the nearly $13,000 in damage to the fuel system that the fuel pump failure caused. BMW eventually relented and advised it will complete all repairs caused by the fuel pump failure. But it has declined to reimburse me for the "overage" charges I've incurred in towing the vehicle to the dealer and in connection with the rental vehicle they obtained for me. And of course, not a single apology for the harrowing experience that could have resulted in our deaths, nor for the considerable inconvenience caused by this defect that BMW has known about for years.

3EA23001 · High Pressure Fuel Pump Failure
Opened Mar 17, 2023 · No close date supplied
Status: open (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337

The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
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.

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. 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.
