New Car Assessment Program
The 2002BMWZ4 carries 6 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2002 Z4 is steering with 3 filings, followed by electronic stability control (esc) (1) and wheels (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 34 investigation files overlapping the 2002 Z4. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

NEVER THOUGHT TO ASK WHY..BUT VEHICLE ALWAYS HAD A DETENT QUIRK SINCE 2003..JUST THOUGHT IT TYPICAL FOR HOW A SPORTS CAR WAS DESIGNED. AFTER CHECKING OTHERS SIMILAR PROBLEMS I GUESS I'VE BEEN MISLED INTO BELIEVING THAT WAS TYPICAL AFTER ALL THIS TIME.TAKING IT TO THE DEALER IN THE NEXT FEW DAYS TO SERVICE PROBLEM. IF YOU HAVE A PROBLEM LIKE THIS DETENT THING GET IT CHECKED OUT BEFORE A BAD SITUATION REALLY HAPPENS. *TR

IF I DO ANYTHING MORE THAN A SLIGHT ROTATION, DYNAMIC STABILITY CONTROL SYSTEM HAS BEEN STARTED, IF THE CURVE WENT TO THE RIGHT, I HAD TO "JERK" TO GO STRAIGHT TO RECTIFY THE SAME, IF IT WENT.

THIS SITUATION WILL NOT OCCUR AT LOW SPEEDS. UNFORTUNATELY, I HAVE A LOT OF PROBLEMS WITH MY 2003 BMW Z4 STEERING WHEEL. THIS IS COMPLETELY UNSTABLE. FOR EXAMPLE: 1) TO MAINTAIN PULL TO THE LEFT OR RIGHT. IT REQUIRES CONSTANT ADJUSTMENT, SO THAT I CAN KEEP THE CAR ALIGNED OR CENTER. 2) I MET A
