2023 BMW X3

The driver-side front door sometimes gets stuck and cannot be opened from the outside. Additionally, the left rear door cannot be opened from the inside. This issue has been occurring since [provide the earliest date you remember, e.g., “mid-2023”] and happens intermittently. It poses a serious safety risk in case of an emergency, as passengers may be unable to exit the vehicle quickly. The problem has not been confirmed or repaired by a dealer yet. There were no warning lights or error messages related to this issue. Additionally, the air conditioning system is not functioning properly, and there is no cold air even when the A/C is turned on. This issue started around [2024], and no warning lights were displayed.”

The contact owns a 2023 BMW X3. The contact stated while driving at an undisclosed speed, the vehicle independently accelerated. The contact depressed the brake pedal however, the vehicle independently accelerated. The contact also stated that the failure had previously occurred several times. The vehicle was scheduled for an upcoming service appointment. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and advised the contact to schedule an appointment with the dealer. The failure mileage was approximately 20.

The 2023 BMW X3 is equipped with automatic high beams that includes an anti-dazzle feature. The anti-dazzle/non-glare (matrix) feature have been available on non US Spec vehicles since 2013 but US legislation did not allow this feature to enabled in the United States. In the meantime legislation has changed however my BMW has been decoded by the manufacturer so that my car does not have that feature and they cite legislation as the issue. My car is capable of the feature but bmw is refusing to enable it thus reducing night time visibility and safety for myself and others on the road. I’m also reading there are people and shops who will enable the feature but with only an 80% solution which means there’s a potential to have a lot of cars on the road that are not correctly providing anti-glare to other vehicles. I think BMW should stop decoding (removing) this feature and recall all cars that have been decoded to have the feature re-enabled. This is 100% a safety issue.

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.

I have noticed that my vehicle seems to be lagging behind when driving at the poster speed limit. Other vehicles were catching up rapidly and stacking up behind me. I compared the indicated vehicle speed with two separate GPS devices and found the indicated speed was slower the the GPS indicated speed. At highway speed, 75 mph as indicated on the speedometer, the vehicle is traveling at 70 to 71 mph as reported be the GPS. I confirmed this by pacing another on vehicle with an accurate speedometer. I took my vehicle (2023 BMW X3 with 2218 miles on it) to the dealer for warranty service to address the issue for inaccurate speed reading on the speedometer. They provided me with a BMW service information bulletin (#B26 06 12 SI dated April 2012) which indicated that most speedometers have a tolerance of approximately 10% plus 2.5 mph, being necessary to compensate for negative tolerances in tire diameter and other outside factors. If a vehicle speedometer reads within that tolerance, no repairs should be attempted. This means that a vehicle traveling at highway speeds (75mph) as indicated on the vehicle’s speedometer, the vehicle could be actually traveling at 65 mph. While traveling at 65 mph in a 75 mph speed zone in legal, it is not really safe and leads to unsafe traffic slow downs and possibly road rage incidents. I questioned the impact of the “speed advance” on the total actual mileage the odometer, along with the computed MPG performance of the vehicle. Interesting enough, the service bulletin notes that the mileage does not incorporate any “advance tolerances” yet it obtains its information from the same source as the speedometer. A 10% “speed advance” (as identified) is unrealistic, unsafe, and unnecessary. Additionally, as related to tire diameter, as a tire wears and thus has a reduces circumference indicate speed becomes higher than actual speed, thus negating the need for the speedometer advance. I want an accurate speed reading while driving.
