BMW X4 Problems — All Years, Common Issues & Reliability

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. Elevant was about 12,000 feet.

We had snow this afternoon and my wife drove the car home from work. We live on a private road and have a steep driveway. I had her park the car in the road while I plowed the driveway. There was only 1-2” of snow on the ground. My wife existed the car. It appeared to be off and in park meaning the engine was not running and the car sat still on a grade. In hindsight, I should have had her set the park brake. My wife went down to her house taking her key with her. I was plowing the driveway. The car had been sitting still on the road for at least 15 minutes. When I was plowing, I had the other key in my pocket. When I got next to the car while still operating my plow, I noticed the taillights came on. Next, the car began rolling down the hill on its own. Nobody was in the car. I was chasing the car. I noted the rear tires were rolling. They were not sliding. The car contained to roll forward then veered towards the side of the road that has a steep ditch. The car then slide sideways down the embankment and stopped at the bottom of the hill. Fortunately, the car did not rollover. Had it been dry and now snow, I think it would have rolled over sideways due to the steep pitch but instead it slid in the snow. I think I was lucky and there is no significant damage but I have not fully retrieved the car out of the ditch yet. I suspect the car was in the start stop mode and possibly my wife did not put into park before exiting the car but this could be easily done since it has the push buttons shifter and the engine was off. Not sure if this is what happened, it’s just speculation. This could have been much more serious if this happened with other people or cars around.

On several occasions, the brake pedal has gone soft. Giving you the feeling that you have no breaks. on the highway when this happens, the brake pedal goes soft and then about halfway into the pedal the brakes lock up and the car veerers sharply in one direction or another. On residential street my wife was using this car this morning to take our son to daycare when she applied the brakes and ended up going through a stop sign as the brakes did not grab until she came to an extreme halt in the middle of the intersection, she then said the brakes were functioning but soft for the next 4 to 5 stops after that they went to completely normal. We had the car in a dealer last week before this incident happen where they verified that the brakes were in good working order Please note that the dealer put new brakes on three weeks ago. I’ve done some reading online and found that there’s recalls in other countries for the same problem but for some reason, my vehicle doesn’t have a recall for this. It is extremely scary when it happens.

A week ago, the steering wheel locked and the braking system and airbags and cameras malfunctioned. We took it for service at BMW. They said the battery caused the malfunction. On thanksgiving day, we were going around 25-30miles per hour when we slammed on the breaks and the breaks didnot function and we could not stop the car. The automatic emergency breaks never activated. We lost power of braking and brakes locked and we impacted a car in front of us with damages to our car and the other vehicle.

Dear National Highway Traffic Safety Administration, I am writing to report a significant safety concern involving my 2022 BMW X4 M40i. The issue pertains to an anti-corroding substance inside the tailgate panel that has been leaking, causing damage to my vehicle's bumper and obstructing the view on my rear camera. This issue not only compromises the structural integrity of the vehicle but also poses a serious safety risk by obstructing the view from the rear camera, which is essential for safe reversing and parking. Despite taking my vehicle to Gainesville BMW for inspection, the problem remains unresolved. The Service Manager, Jose, initially acknowledged the issue but has since avoided taking appropriate action to rectify the situation. In addition, I have been in contact with Jerry from BMW Customer Relations, who has been unwilling to communicate via email as per my request. Instead, he insists on discussing the matter over the phone, which I find concerning given the importance of maintaining a documented communication trail for this serious issue. The ongoing leakage and damage to my vehicle not only compromise its functionality but also raise concerns about potential long-term safety risks. As such, I am seeking your assistance in addressing this matter to ensure that BMW takes the necessary steps to resolve this defect and prevent further safety hazards. I appreciate your prompt attention to this matter and look forward to your guidance on the next steps. Thank you for your time and assistance.
