2003 BMW Z4 Engine And Engine Cooling Problems

The contact owns a 2003 BMW Z4. The contact stated that the coolant warning light illuminated. The contact then stated that she noticed smoke underneath the hood of the vehicle. The contact stated that upon inspecting the vehicle, she noticed a leak on the ground located near the rear passenger’s side tire. Additionally, the contact then stated that while operating the convertible drop top, she heard an abnormal sound in the motor. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 64,000.

THE POWER STEERING ASSIST HAS FAILED ON THE CAR MAKING IT VERY DIFFICULT TO STEER. LUCKILY IT FAILED WHILE ON A STRAIGHT PART OF AN INTERSTATE AS MY DAUGHTER WAS DRIVING THE CAR AND THIS SEVERELY FRIGHTENED HER. SHE DID NOT OVERREACT AND WE TOOK APPROPRIATE MEASURES TO GET THE VEHICLE HOME. ONLINE RESEARCH INDICATES THAT THIS ISSUE WAS BEING INVESTIGATED BY NHTSA IN 2010 BUT CAN NOT FIND ANY INDICATION THAT AN ACTUAL RECALL IS IN PLACE. THIS IS A VERY DANGEROUS THING TO HAPPEN, ESPECIALLY IN A STATE WITH A LOT OF WINDING ROADS (TENNESSEE). I PURCHASED THE CAR USED LAST YEAR AND ALSO HAD A WATER PUMP FAILURE THAT RESULTED IN A BLOWN ENGINE. I WISH THIS ISSUE HAD BEEN INVESTIGATED ALSO AS I UNDERSTAND THAT IT IS A COMMON FAILURE WITH THIS PARTICULAR ENGINE. THERE IS ALSO A PROBLEM WITH THE SPEEDOMETER AND FUEL GAUGES READING...
