2013 BMW X3 XDRIVE35I power train 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…”

“The contact owns a 2013 BMW X3. The contact stated that while driving at an undisclosed speed, the contact became aware of an abnormal sound coming from the vehicle, with the drivetrain warning light illuminated. The vehicle was towed to an independent mechanic where it was diagnosed with a stretched timing chain. The contact was informed that the timing chain needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 93,000.”

“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.”

“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.”

“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.”
