2013 BMW X3 Powertrain & Transmission Problems

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.

There has been no communication from bmw regarding the engine coolant pump recall besides the initial notice of the recall. I have not been able to drive my vehicle for almost 3 months because the engine coolant pump could leak onto electrical components and cause a fire. I have been unable to obtain a loaner vehicle during this time and this is affecting my livelihood.

As I was backing up, my car suddenly accelerated. I was shocked and tried to brake as fast as I could. I did slow down, but still hit a car that was parked nearby. This happened at a gas station. 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.

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.

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

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

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 ON THE HIGHWAY IN HEAVY TRAFFIC, A LIGHT CAME ON AND SAID SOMETHING ABOUT OIL PRESSURE ETC. I COULDN'T READ EVERY WORD, I HAD TO KEEP MY EYE ON THE ROAD. I PULLED TO THE SIDE OF THE ROAD BUT THE CAR STOPPED RUNNING AND I BARELY MADE IT TO THE BERM. IT WAS TOWED BY AAA TO A SERVICE STATION WHO DIAGNOSED THAT IT "JUMPED TIME" AND THAT WAS A KNOWN PROBLEM WITH THIS CAR. THE ENGINE WILL HAVE TO BE REPLACED.

AT 85000 MILES DRIVETRAIN MALFUNCTION LIGHT CAME ON. COULDN'T GET CAR TO CONTINUE DRIVING. MECHANIC EXPLAINED THE DIAGNOSIS SHOWED A TIMING CODE. THIS IS THE 5TH TIME CAR WAS IN THE SHOP SINCE THE PURCHASE FROM CARVANA ON JULY 2ND 2020. TOLD A NEW ENGINE IS NEEDED..

TIMING CHAIN ISSUE. I HAVE A DRIVETRAIN WARNING IN WHICH I HAVE READ NOTHING BUT COMPLAINTS ON THIS. TIMING CHAIN BREAKING EVEN WITH VERY LOW MILE AND YES I AGREE WITH THE PUBLIC THAT THIS SHOULD BE A RECALL DEAL. THIS SO BAD FOR BMW WITH THEIR REPUTATION FOR BEING SUCH GOOD CARS.

MY VEHICLE HAS 98,902 MILES AND I HAVE BEEN GETTING A 'DRIVETRAIN MALFUNCTION' ERROR MESSAGE WHILE DRIVING ON THE HIGHWAY. I TOOK THE CAR TO TWO MECHANICS AND WAS TOLD THAT I NEEDED TO REPLACE THE TIMING CHAIN. AFTER DOING SOME RESEARCH TO FIGURE OUT WHAT THIS ISSUE IS, I FOUND COUNTLESS FORUMS OF OTHER OWNERS HAVING THE SAME ISSUE.

low oil pressure light then Drivetrain malfunction light came on car completely shut off, no steering, no control very hard to get it to the side of the road. Would not go into neutral for tow, had to be dragged onto a tow truck bed. BMW knows of this problem with the PLASTIC drivetrain, BMW still refusing to recall this car, or engine. MANY COMPLAINTS ONLINE!!! CLASS ACTION LAWSUIT APPARENTLY IN PROCESS. I replaced the engine in this car, now 2 years later same DRIVETRAIN problem. Told car needs another engine. Why should the little guy have to deal with this cost and danger!! BMW should stand up and recall this car 2013 x3.

STOPPED AT A STOP SIGN IN A RESIDENTIAL AREA, WARNING LIGHT CAME ON INDICATING A DRIVERTRAIN PROBLEM, CAR LOST POWER. RESTARTED CAR; WOULD ONLY MOVE SLOWLY (AT 20-30MPH). COMPUTER RECOMMENDED DRIVING MODERATELY. LATER GOT THE PROBLEM FIXED BY LOCAL DEALER. ABOUT 5 MONTHS LATER, SAME ISSUE OCCURRED. STARTED CAR AT WORK TO DRIVE HOME. SAME WARNING LIGHT CAME ON INDICATING THE SAME ISSUE. CAR WOULD MOVE ONLY AT UP TO 30MPH. LUCKY BOTH TIMES THE PROBLEM CAME UP AT LOCAL STREETS. IF ON HIGHWAY, CATASTROPHIC CONSEQUENCES WOULD OCCUR.

START/STOP SWITCH CAUSES TRANSMISSION MALFUNCTION STOPPING FORWARD MOTION OF VEHICLE FROM STANDING START CAUSING FAILURE TO PROCEED SUDDENLY. TURNING OFF THE SYSTEM IS THE ONLY WAY TO STOP THIS FROM HAPPENING. DANGEROUS SITUATION PULLING INTO TRAFFIC IS THE RESULT. THIS HAS HAPPENED DAILY.

TL* THE CONTACT OWNS A 2013 BMW X3. WHILE DRIVING 25 MPH, THE VEHICLE WOULD NOT PICK UP SPEED AND STARTED HESITATING. THE CONTACT STATED THAT THE DRIVETRAIN WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE ENGINE AND TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 45,000.
