NHTSA Complaint #10578539 — 2004 BMW Z4

THE STEERING BECOMES "STICKY" WHEN THE WEATHER IS WARM. WHEN DRIVING STRAIGHT IT RESISTS TURNING AND ONCE TURNED TRIES TO STAY TURNED AND THE CAR TENDS TO VEER UNINTENTIONALLY. THE STEERING WILL NOT RETURN TO CENTER WHEN THE WHEEL IS RELEASED AND IT IS DIFFICULT TO STEER SMOOTHLY ON THE FREEWAY AND REQUIRES CONSTANT CORRECTION. WHEN IT IS COLD IT STEERS FINE AND TRAVELS DOWN THE FREEWAY PERFECTLY WITH NO HANDS ON THE STEERING WHEEL AND CORRECTIONS CAN BE MADE WITH ONLY TINY EFFORT. WHEN IT IS HOT AND STICKY IT TAKES BOTH HANDS AND A FAIR AMOUNT OF EFFORT TO STEER. THIS IS A DESIGN FLAW RESULTING IN A SAFETY ISSUE THAT BMW SHOULD FIX UNDER WARRANTY REGARDLESS OF AGE. *TR
