NHTSA Complaint #10532164 — 2004 BMW Z4

FIRST NOTICED THE ISSUE IN 2009 AFTER A LONG DRIVE ON A VERY WARM SUMMER DAY IN NEW YORK. STARTED NOTICING A "STICKY/CHOPPY" REACTION TO THE AUTOMATIC STEERING WHICH BECAME PRONOUNCED WHILE ON A CURVE, AND REQUIRED QUICK ACTION TO "RIGHT" THE WHEELS TO AVOID A CROSSOVER TO THE OPPOSITE LANE. I BECAME MORE AND MORE AWARE OF THE PROBLEM AS IT SEEM TO RELATE TO LONG DRIVES ON HOT DAYS. SINCE THIS VEHICLE IS ONLY DRIVEN IN THE SUMMER TIME, I CAN NOT TESTIFY TO THIS STEERING PROBLEM IN THE COLDER WINTER MONTHS. HOWEVER, I AM CONSTANTLY VIGILANT TO THIS ISSUE NOW. CONTACTED BMWNA TO CHECK FOR RECALLS, BUT RECEIVED NO RESPONSE OR ACKNOWLEDGEMENT THAT THE STEERING WAS FAULTY. THIS COULD BE A DANGEROUS SITUATION, AND I ASK FOR YOUR SUPPORT IN CONTACTING THEM. THANKYOU *TR
