2024 BMW 340I Recalls & Complaints

Incident: May 31, 2024 · Filed: June 20, 2024

I was driving on an empty highway at about 55 mph and all of a sudden heard a loud bang, after i pulled over i saw that my sunroof was shattered, bmw declined a warranty on it but the car had only 3k miles on it, prior to that accident i was hearing some squeaking noises from my sunroof when it was in fully closed position. After taking it to the dealership not only they declined on the warranty but they failed to investigate and explain the cause stating it was probably the rock hit the glass the caused the problem, i taped the sunroof after it shattered and after i was picking up the car the tape was still there and was at the same condition prior leaving the car there, so that tells me that they didn't even chacket it.

The rear cross traffic alert system is a major safety issue on my 2024 BMW M340i. It basically does not operate. To get any kind of notification that there is a vehicle approaching from either right or left if you are backing up the approaching vehicle has to be traveling at a speed greater than 7 mph and then you only get an alert within 2 seconds of impact. This is a pointless operation as then it is too late to avoid a collision. The window is to narrow to provide any useful alert and safety function. Also, I receive no alert if a pedestrian should be walking behind the vehicle nor a small child. I had this issue checked at my dealership and was told the system is operating as intended. So I then escalated it to BMW of America customer service. After some back and forth with BMW of America CS as they had initially defaulted to the dealers stated finding (operating as intended) they agreed agreed to send a factory Engineer to the dealership to look at the issue after I said I would report the issue to the NHTSA . The field engineer was at the dealership on 3/11/2024 he checked my car for the issues and determined the Rear Cross Traffic Alert System is operating as designed. This is an unacceptable response and an unacceptable operation of a safety system. BMW uses this feature as a selling point to make customers believe that this a a fully functional safety system and it enhances general safe driving. There are many complaints on multiple BMW forum sites that state the same issue with many models and years of BMW's.
