BMW X4

Windshield crack around heating elements and rearview mirror mount. There 3 cracks that extend to top of windshield to a horizontal crack. These look like one hook, J and a staightline that forms right angle to the one about a foot long behind readview mirror mount. There are no rocks chips evident. This occurred in a time span of 80 minutes. I actually heard the popping or cracking like when a plastic bottle air is restricted during elevation climb or desent but did not know what it was.…

I am reporting a safety concern regarding BMW vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found on models from 2019 to 2021. The oil pump in these vehicles is failing prematurely. I was told this by service technicians at BMW and confirmed it through my own research. The oil pump failure is due to a plastic adjusting ring breaking. The result is severe oil pressure loss and engine failure. This is uncommon for a vehicle that has 65k miles. The engine failure comes…

Went to sit in driver rear seat and put on my seat belt and found it frayed apart. Thought this was od and tried the rear passenger side only to find the exact same thing. Took it to the dealer in Visalia, CA. They said that they have never seen anything like that before. After discovering that both belts were broken in the same spot, they concluded it must be caused by wear in the retracting mechanism, but because the car was out of manufacturer's warranty they could only sell me new ones. I…

BOTH rear seat belts have broken off in the same spot. Went to use the driver's side rear seat belt and found it had been broken (frayed off). Moved to the passenger side and found the exact same thing. This could have been a bad situation if in an accident had occurred where they had not completely frayed but would have failed. Took it to my local dealer and they had no answers as to how this could have happened but suggesting that it most likely happened inside the recoil mechanism. They…

I am filing a complaint regarding what I believe is a manufacturer defect in my BMW vehicle. During a recent visit to an authorized BMW dealership for a routine oil change, I was informed that the front tension joints (tension struts) must be replaced because the rubber bushings/gaskets are cracked and leaking fluid. My vehicle has fewer than 33,000 miles, and I drive infrequently. This was missed during the last oil change which was 6-8k miles ago. This type of failure at such low mileage is…

We heard a whining sound under the hood on November 1st, 2025. Prior to noticing this noise, there were no warming lamps or messages appearing. Following a short drive we smelled burning in the garage. We did not drive the vehicle the following day and intended to take it to our mechanic on Monday morning, the 3rd. Upon trying to start the car it was dead. We had to have it professionally jumped as standard jumping with our personal jumper cables would not start it. Our mechanic explained both…
