2021 BMW 330E Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

What this page shows

Everything below is an owner-reported complaint submitted to NHTSA about the 2021 BMW 330E, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.

Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail

What the reports in each category say, in the owners' own words

Electrical

Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.

reports

From owner reports, verbatim

1. The engine starter motor (specifically the pinion starter) has failed, and the auxiliary battery is also showing reduced capacity (only a portion of its 660 cold cranking amps). The vehicle is currently at a service center where the technician has diagnosed these issues. The components should be available for inspection upon request, as they have not yet been replaced. 2. The failure of the starter motor and battery primarily affects the vehicle's ability to start. While this could potentially strand you in an unsafe location, the information provided does not indicate any specific safety incident or risk that occurred during operation. No direct safety hazard has been reported. 3. Yes, a technician has diagnosed the problem and confirmed a fault code in the drivetrain related to the failed starter motor. The technician also identified the auxiliary battery's reduced output. This confirmation comes from a service center, which could be a dealer or independent shop. 4. The only inspection mentioned is by the technician at the service center. There is no indication that the manufacturer, police, insurance representatives, or others have inspected the vehicle or components. 5. Yes. Prior to the failure, when starting the car in the early morning, a "drive train service" message appeared on the display, advising you to visit a service center as soon as possible. This warning was the first symptom of the problem before the starter ultimately failed and the battery drained. This aligns with the technician's diagnosis of a drivetrain fault code related to the starter motor.

On 5/22/24 had a catastrophic failure of the Electric Motor Electronics and 12v Battery. I have requested that the BMW Serice Assistant provide me with all affected parts for inspection. Shutdown of the vehicle high voltage system could result in a crash. When this part fails along with the 12v battery you lose control of all vehicle electronics (steering, braking, electrical power, and propulsion). Yes, there was a previous voluntary recall campaign 19V-599s Service Information Bulletin (Revision 2) which replaced SI B12 27 19 dated October 2019 by BMW for this device. The vehicle and component has been inspected by the Richmond BMW Service Technician. I started to experience problems with the vehicle in late April and took it in for servicing and repair in early May. I was told that the problem was a computer programming recall that was fixed.

In Buford GA at the corner of Elm Tree Terrace and Buford Dam road, I was waiting for the light to turn on a decline. It is important to note that the car was driving in all-electric mode on a full charge. Once the light turned green I stepped on the accelerator to go and the car stalled. I believe the transmission slipped. The gears caught at high torque and jolted the car involuntarily forward. I didn't notice it at first but after a couple of sleepless nights with shoulder pain: I got an MRI and was found to have a torn rotator cuff. It is difficult to associate the injury as it is hard to access the force applied to the jolt. The only word I can use to describe the force of the jolt was violent. I believe there is a safety issue when a high torque electric motor is being run through a slipping or failing transmission and I suspect as a result I have suffered a injury as a result.
