This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Occasionally when the adaptive cruise control is active, the collision warning will light and the brakes automatically applied even though there is nothing in front of the car. This has occurred on a straight, flat road with no shadows, undulations, or cars anywhere in sight. This is a huge safety hazard since it has happened with cars traveling immediately behind me at a high rate of speed. BMW techs cannot id the problem and say they have never heard of it. The problem is infrequent and highly unlikely to occur during a test drive. Met today with a BMW na technical service expert who insisted that I was 'confusing' this problem with the system's normal operation. Not so. My lease ends in 2 months and I don't want the next owner to get rammed from behind.
When at a complete stop the car hesitates to accelerate. There is a two - three second delay after you step on the accelerator. This has resulted in almost being hit broadside on several occasions. The car literally drifts for a few seconds before responding. Way scary and very dangerous. Afraid to cross lanes with oncoming traffic. The fuel saving auto/on/off has always been disengaged when this occurs. Not using sport or eco setting either. Very unsafe car. Problem has existed over the past 14 months since purchased new. Have complained about problem to dealership and BMW North America numerous times. BMW tried to update software but it didn't address problem. Others on bimmerfest in the usa are also stating they are having a similar problem. Please help. I bought this car new at a price of over $40K.
