Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While the car was plugged in overnight in the garage, (it is a hybrid), a terrible odor was released and carbon monoxide was detected. Fire department was called twice (this occurred two nights in a row) and detected high levels of co from inside the car and from the hood. We needed to evacuate the house each time. Gas company and plumber confirmed there was no other issues in garage. Upon removal of the car, issues no longer persist. Bmw cannot find anything wrong with the car, but I refuse to take the car back, given safety for my family. …”
NHTSA complaint #11269386, filed 2019-10, 18,000 miles“Hybrid battery has a failed cell. It was confirmed by BMW diagnostics but BMW refused to repair/replace failed cell even though it was under full 8yr/80k mile warranty. BMW claimed it as wear and tear, even though 1 out of 5 cells completely failed. The failure caused the car to run at reduced speeds causing others cars around me on the freeway to be in danger as all of sudden I am unable to reach freeway speeds due to part failure. There was an error stored in the car per BMW diagnostics that called for failed Cell to be replaced per notes of the technician who ran the diagnostics. …”

The Fire Department was called to the residence, but the flames had self-extinguished. The Fire Department inspected under the hood of the vehicle and confirmed that there was a small. …”
NHTSA complaint #11768329, filed 2026-10, 120,000 miles“Unsure of the exact cause, appears to be the high voltage battery/electric drive function that is faulty. It is creating a hazardous condition causing the vehicle to propel itself forward while driving in traffic and almost hitting other vehicles on the roadway when the electric drive fails or it switches between battery and the engine. If it’s not propelling itself forward, it’s unexpectedly decreasing power and preventing the vehicle from driving after stopping for traffic, traffic signals and traffic signs. Increasing the risk for a rear-end collision. …”
