Power Train Problems of BMW X3 - part 2

I'm reporting a safety issue with BMW vehicles equipped with the b58tu engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle disablement. Warning signs, when present, include inability to measure oil level electronically, abnormal oil pressure, or sudden drivetrain malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants exposed to freezing temperatures while awaiting assistance. Pump replacement requires extensive disassembly and commonly costs $6,000-$8,000, assuming no engine damage. A critical concern: owners cannot determine if their vehicle has the original plastic pump or the later metal revision. BMW's VIN-based parts lookup now shows updated components even when original plastic parts remain installed, and BMW has removed the original plastic part number from dealer networks entirely. Failures are reported across multiple production years, and the scope of affected vehicles remains unclear. Because this condition causes sudden vehicle disablement without adequate warning, especially in cold weather, I believe this warrants investigation as a potential safety-related defect.

I have a 2014 X3 xdrive28i with 114, 000 miles. On August 4th 2024 while I was going 15 miles per hour on a residential road, when my idrive instrument notification panel displayed "drivetrain malfunction! pullover shut off engine". I immediately came to a stop and turned off the engine, I was unable to re-start it afterwards. I had it towed to my local ralley BMW dealer, where it then restarted after being removed from the flatbed tow truck. They were unable to determine the cause of the issue. They did a software update and told me that was probably all it was. I soon found out there is a massive issue with the timing chain & chain guides that can cause the timing to skip, resulting in premature shutdown or catastrophic engine failure. I took it to a reputable independent shop who later identified that the timing chain had excessive slack and was not able to be adjusted for proper tension, due to the catastrophic failure of the timing guides. Required repairs will cost upwards of $4,000. 00, which I am currently in the process of completing.

I am reporting repeated coolant system failures and overheating on my 2019 BMW X3 . I have had 4 coolant-related repairs in under 3 years, including the coolant reservoir boiling after service. Most recently, the problem recurred despite prior repairs. This is a certified pre-owned vehicle with warranty history, and I believe this is a systemic engine/cooling defect that poses a risk of engine failure or fire. Other owners may be affected. A recall or investigation is warranted.

The contact owns a 2018 BMW X3. The contact stated while his wife was driving 65 mph, a message advising to stop driving was displayed, and the vehicle simultaneously shifted into neutral(n) independently. The vehicle stalled in the middle of the highway and failed to respond while depressing the accelerator pedal. The message advising to drive with caution was displayed after several minutes, and the contact was able to continue driving upon depressing the accelerator pedal. The vehicle was taken to an unknown dealer to be diagnosed. The vehicle was not diagnosed or repaired. The vehicle was then towed to the local dealer, where it was diagnosed that coolant was leaking from a hose. Additionally, the dealer informed the contact that excessive engine temperature could have damaged the cylinder head and the rod bearings. The dealer recommended replacing the engine. The vehicle was not repaired. The contact stated that his son-in-law then towed the vehicle to another facility, where the vehicle was diagnosed by a mechanic; however, no engine failure or coolant leak were found. The contact related the failure to an unknown recall. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 152,942.

Summary of complaint: we own a 2007 BMW X3 SUV that we have taken to the BMW mt. Laurel NJ dealership for service since we bought the car over five years ago. On August 15th 2023, we took the car for a scheduled service and oil change. We paid $3000 + and brought the car back home first week of September when the car was purportedly repaired. My husband noticed that the car was not driving quite well. The steering was tight. When we called BMW they told us it might take a few drives for things to get back to normal. Then our 29 yr old daughter came from nyc where she resides to visit is for the weekend. On Sunday sept 10th 2023, she went on an errand for us to moorestown area. At a stop sign when she was not moving the car, the car started a spin in all directions. The oncoming vehicles thankfully avoided hitting her and she was able to come to a stop. Our daughter was terrified. After calming down she called to let us know what happened. She was so shaken up she barely managed to drive back home. We then called BMW right away when they opened on Monday and told them what happened. They came to pick up the car from our house to check it out and see why it spun out of control in circles. Then the service dept called and said the car spun out of control due to a transfer case issue. I then questioned them why they did not properly diagnose this initially instead of us wasting $3000+ on repairs and still the car was not safe to drive. I then contacted robert durante the asst service manager and he has not been too nice. BMW should do the right thing. I just paid over $3000 for car repairs in September and car did a spin out on sept 10th less than two weeks after repairs was completed. The car was worse off when repairs was completed than when I brought it in. Way I see it, an inexperienced mechanic or a negligent mechanic worked on our car. I have never had any problems with repairing our car with the dealer service department till this incident.

Rear differential bolt failure: failure has not happened yet, but will happen eventually with enough mileage as seen with many other BMW X3m vehicles. Problem is with the rear differential bolt. The bolt is prone to shearing or snapping, noises may be heard from differential up until failure occurs at some point. Once this occurs it can wreak havoc on the differential and associated parts and cause thousands of dollars worth of damage if you are outside of the warranty period. The bolt needs to be stronger or something needs to be added to the bolt area to lessen the movement of the differential under power. If bolt is to snap on the road this will cause safety issues as you will lose power and potentially break many things on vehicle that could cause road debris and also require you to pull over immediately. Problem can't be reproduced as it's a single bolt that can fail at any time. No inspections have taken place, no warning lights or problems before hand. However, some may hear noises in the rear differential under power.

Severe clunk while in reverse probably coming from rear differential.

Was driving the vehicle home and while driving I heard a loud pop and a thump. Had the vehicle towed home to see that the real differential bolt had sheared off the head!.

The issue is with the rear differential carrier bolt, part # 33176760336. This bolt shears at the hex head and causes the differential assembly to misalign with the rest of the driveline components and causes further failures of the driveshaft and other items. Just in the past month I have seen several people post on the BMW X3m facebook groups and also on internet forums about their broken bolt causing issues. The oem bolt is a 10. 9 grade bolt that does not appear to be able to take the stress put on it for daily driving. My car is exhibiting symptoms that others have heard in their cars before the failure occurred, clunking when putting the car into drive or reverse. This can also be heard while going into second gear and driving at 5-20mph on light throttle then letting off the gas pedal and getting back on, this will cause the differential to clunk back onto the bolt and off. This is a failure due to a simple bolt component that could be enhanced by BMW to a higher tensile strength to avoid this situation from happening on the highway.

The contact owns a 2022 BMW X3. The contact stated that while accelerated at an undisclosed speed, the vehicle inadvertently decelerated while the accelerator pedal was depressed. The service vehicle warning light illuminated. The contact then stated that a message displayed on the dash indicating “drivetrain malfunction”. The vehicle was taken to the dealer where the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 11,712.

After taking off from a stop light, heard a loud bang and after taking it to the dealer it turns out to be a broken rear right axle and diff retaining bolt. My car is a 2022 my with 20k miles on it. This was the first time I have done a "hard launch". The car is bone stock, with no modifications whatsoever and all maintenance and repairs done at the BMW dealership. I am going after a warranty claim as this should be covered.

Consistently breaking differential bolt that hold the rear differential in place, very widespread issue as well as being consistently noted in forums. Also a high number of differential completely failing across all years. Mine failed recently, two other vehicles at the same dealership had a broken differential. There needs to be a recall on both of these issues.

The rear differential bolt is a known failure point on these cars. I see it time and time again where there is a clunk noise coming from the rear of the car and sure enough, the bolt has broken on the rear differential and leaves the car undriveable. BMW has said that they are unable to do anything without NHTSA informing them of the issue. There needs to be a recall or active service bulletin to address this issue. This failure is not a matter of “if”, it is a matter of “when”. There needs to be a stronger bolt in place otherwise it is a near $5000 repair to replace the rear differential if not covered under warranty.

Drivetrain malfunction popped up and the car cut off and went into neutral while driving on the road which almost led us to lose control and wreck. Many issues with the fuel pump.

The differential is making clicking noises at low speed especially when on and off the gas.

Rear differential disconnected from vehicle due to mounting bolt snapping, rear differential was also previously replaced by BMW before I purchased vehicles due to rear differential failure.

When the vehicle is moving at a speed of 4mph and lower, it is impossible to shift the vehicle from neutral to drive without applying the brakes. I was pulling out onto a 4 lane road from a side street when I accidentally bumped the transmission gear shifter into the "n" neutral position. When I realized this (I was only going 4 mph at the time) I tried to shift it back into drive but it would not work. The vehicle made a sound that I was doing something wrong. I tried to shift it again (vehicle was probably now moving around 3 mph) and it gave me that same warning sound but this time I looked at the instrumentation panel and saw that the warning text displayed on the panel said that I needed to apply the brakes before I could shift it from neutral to drive. When I applied the brakes the vehicle came to a complete stop because I was going only 3mph and at that point I could shift the vehicle into drive. I believe that if I had pulled out with cars coming at a high rate of speed that I could have been hit on the drivers side because I had come to a complete stop in the right hand lane of the roadway. I could only imagine what could have happened to an inexperienced driver because I somewhat panicked and I have over 35 years of driving experience. This safety issue was brought up to BMW through their customer service/satisfaction center. The representative that I spoke with said he would forward the concern to their "research and design" unit but didn't know if they would respond. I have not brought the issue up with the dealership where I purchased the vehicle because I notified BMW directly. I am concerned that this design fault will one day cause catastrophic injuries.

Drivetrain malfunction light due to bad egr valve, which is causing car to run rough. Currently there is safety recall out for the egr cooler. BMW of bloomfield diagnosed and recommended egr valve replacement but cost was excessive at over $1,100. Another BMW specialist (g&t in jersey city) recommended replacement of egr valve and cooler due to potential hazardous conditions described in safety recall but said I shouldn't have to pay due to safety recall. So I called BMW dealers in bloomfield and springfield both say the "remedy is not available". So am I just supposed to drive the car until it catches fire? this seems reckless so my other option is to pay the mechanics to replace the system that is already subject to a recall.

This vehicle shuts down the engine when stopped at a stop sign or light. The engine resumes when you press on the brake or gas peddle. But sometimes, the engine will turn back on for no apparent reason. That is not an issue of concern. But, sometimes, when the engine turns on automatically, it will drop the transmission into park. So when you attempt to apply gas, the car will not move forward as it is not in gear. This is intermittent. My german auto repair shop has observed the issue and spoken with many other shops who have reported the same issue with the X3. BMW does not have a solution to the problem. The driver never knows if the car will move forward after a traffic stop, as it is not obvious that the transmission has dropped into park until you attempt to move forward. Instead of using this engine turn-off feature of the vehicle, they suggest turning it off to avoid the problem. That is a gas-saving feature of the car.

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.

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.

In July 2022, the vanos bolts in my 2011 BMW X3 xdrive28i failed, causing major internal engine damage. This is the exact defect later identified under BMW recall 23v-707. The bolts sheared off while driving, disabling the vehicle. I paid $5,000 out of pocket for full repairs using oem parts at masny motorwerks (BMW specialist in rochester, NY). BMW did not issue the recall until more than two years later. At that time, there was no remedy available. A fix was not released until December 2024. I followed BMW’s reimbursement process: I visited BMW of rochester in person on January 28, 2025 and submitted my invoice to the service advisor. I followed up by phone twice — no response. I submitted a full reimbursement claim to BMW north America on March 31, 2025 with all documentation. BMW replied on April 8 with a boilerplate response redirecting me back to the same dealership. I then followed up again with full documentation. BMW replied again, refusing to take responsibility and offering no support. I have submitted everything twice and followed the tread act process in good faith. BMW has failed to reimburse me or process the claim properly.

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.

Vehicle engine rpm will arbitrarily increase from 500-600 rpm to 1200-1500 rpm while idling in drive and at operating temperature, such as at a stoplight or in a drive-through. The vehicle also makes a distinct clunking sound under normal stop-and-go driving conditions.

My digital gauges were frequently going off center in my vehicle. I scheduled service with the dealer however they did not have a loaner available for weeks so they scheduled the appointment for a few weeks out, my car subsequently completely died on the road and after a minute or two I was rear ended by a truck and the car was completely totaled.

My drive belt got worn out and when it snapped it got sucked in to the engine and warped around my timing chain I started looking into it and this has happened to a lot of people who have a BMW X3 and the shop told me that because they have had other BMW X3 but my was the worst that they have seen they have now change there policy for dealing with a BMW X3 when it comes in.

I am working with a journalist at cnbc to get info about this death trap out since NHTSA is ignoring the issue completely. People are telling you their family members are injured and/or dying because 2008 BMW X3’s simply loose power at 70mph and transmission issues that make this care not accelerate, jerk, stall, etc. I have been helping contact other owners in an effort to see if they have any unreported issues and many say their complaints were also ignored. When you try to accelerate, the transmission "thinks" about what gear it should be in. The vehicle hesitates, stalls slightly, and creeps along slowly before second gear catches. The rpms are erratic when accelerating. Very unpredictable when trying to accelerate. The hesitation is the main issue, especially when trying to pull out of an intersection across traffic. It can become a very scary situation when you want to accelerate and nothing happens. This is an ongoing problem. Nothing in particular causes it to happen besides regular acceleration. The problem is intermittent and may disappear while driving. However, it will appear again for no real reason. A software update was performed in mid-July. The problem was still noticeable. On August 3rd, the vehicle was once again brought in for service work. The service manager came along for the drive and noticed the transmission problem. Another 2008 BMW X3 that was on the lot was driven under the same driving conditions. The same issues with the transmission were noted. He told me that they will contact BMW to see if there are any service bulletins on how to correct the problem, but was unaware of any fix currently available. After two service calls the problem still persists without any fix as of yet.

Limpmode: life threatening failure of vehicle shutting down accelerating in heavy traffic in speeds over 70 mph. On 9 Nov 22 I was driving on interstate to take my wife to her radiation appointment. Within 1 mile of exit, traveling in far-right lane in 4 lanes of heavy traffic with an additional two lanes of heavy traffic merging in from the right, I had to get over into the merging oncoming traffic. When I went to accelerate to merge right into the heavy traffic, my BMW dash lit up red and the acceleration was shut off leaving the car coasting. I could not accelerate, stuck in my lane the car started slowing from 70+mph traffic down to 60mph, 55 mph and I was able to get over into exit lanes at 45 mph with car still decelerating up exit ramp. I pulled off to the exit ramp onto the side of the road into the grass/pavement to safety. The BMW’s failure to operate was a life-threatening incident for me, my wife and mother in the car in the middle of very heavy traffic. In addition, all on-coming vehicle traffic was put at risk of life threatening injuries with a high risk of rear end multiple collisons. I sat looking at the dash reading and it read a few minor problems with sensor for pedestrians and cameras and if it proceeded to fail to contact maintenance, however the car was ok to drive. I shut the car off and restarted it and was able to get my wife to her appointment. I drove the car home with no issues. Vehicle was towed to dealership the next day at century BMW where it was purchased and informed by BMW mfg not to touch the vehicle. BMW n. A. Sent engineers to dealership to investigate cause. BMW n. A. Could not recreate environment, however choose to do repairs thought best to resolve issue. BMW n. A. Sent report to dealership for parts order and repairs. My many requests for trouble code reports from BMW n. A. And century BMW starting from 24 Nov 2021 to Jan 2022 were ignored. 18 Feb 22 partial rpt. Received by accident from service rep.

On 9thsept'2021 when my wife driving back from work she got " drivetrain malfunction msg on the screen, she pulled over and called me, I was there in 15mins and did try shut off the engine for few mins and start, it didnt go in 2019 I got the same msg and SUV stalled in the middle of road, I stopped the engine waited for 2 mins and restarted, the msg was gone. When we towed the vehicle to bwm-shrewsbury, he said we need to replace the engine and its going to cost close to $18000 and said he'll try to work with BMW corp long story short I ended up trading the vehicle for low cost and got a new one as the dealer left no choice.

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.

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.

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.
