VEHICLE DEVELOPED SIGNIFICANTLY REDUCED FUEL MILEAGE AFTER THE FIRST 500 MILES. IN TOWN RANGE DROPPED BY 40% TO 7.8 MPG OVER THE SAME ROUTE, INDEPENDENT OF GASOLINE SOURCE OR GRADE. EXHAUST GASES ARE VERY HOT AND EXHIBIT A PRONOUNCED SULFURIC, GUNPOWDER LIKE SMELL. ELECTRICAL FANS CONSTANTLY ON DURING CITY DRIVING ATTEMPTING TO COOL THE ENGINE. EXCESSIVE CARBON BUILD UP ON EXHAUST COMPONENTS. ENGINE EXHIBITING RICH RUNNING CONDITION. A PERSISTENT MECHANICAL ENGINE WHINE DEVELOPED EMANATING FROM THE OIL PUMP, POSSIBLY THE ALTERNATOR AREA OF THE ENGINE COMPARTMENT, PEAKING AT 1700-1900 RPM UNDER LOAD. AT 1,200 MILES, THE 8 SPEED AUTOMATIC TRANSMISSION DEVELOPED ERRATIC SHIFT BEHAVIOR BETWEEN 1ST-3RD GEARS. AT FAIRLY CONSTANT SPEED, THE TRANSMISSION IS SHIFTING BETWEEN 1ST AND SECOND GEAR, ALTERNATING UP SHIFTING AND DOWNSHIFTING WITHOUT ESTABLISHING PROPER GEAR. COMING TO A STOP, VEHICLE SURGES REVOLUTIONS BY UP TO 500 RPM ON THE 3-2 DOWNSHIFT AND UP TO 800 RPM ON THE 2-1 DOWNSHIFT, CAUSING A SUDDEN AND ABRUPT HALT, ENGINE BRAKING EFFECT. BEHAVIOR IS MOST PRONOUNCED IN STANDARD D TRANSMISSION MODE, MINIMIZED IN DS MODE AND COMPLETELY ABSENT IN MANUAL MODE WITH AUTOMATIC DOWNSHIFT. AT 2,200 MILES, GUNPOWDER LIKE EXHAUST GAS SMELL MORE PRONOUNCED AND EVIDENT WHILE AVERAGE FUEL MILEAGE DROPPED TO 6.4 MPG OVER THE SAME COURSE. TRANSMISSION EXPERIENCED TWO INCIDENTS OF FAILING TO UP SHIFT INTO SECOND GEAR FOLLOWED BY A MECHANICAL CLUNK AND SHARP JOLT AFTER FINALLY GETTING IN GEAR. VEHICLE DOES NOT EXHIBIT ANY STORED OR ACTIVE FAULT CODES WITHIN THE ON-BOARD DIAGNOSTICS. *TR
2014
ELECTRICAL SYSTEM
I HAVE LEASED BRAND NEW 2014 BMW X5 ON 12/09/2013. SUDDENLY AFTER 2 DAYS, IT HAS BROKEN. HEATED STEERING FUNCTION STOPPED WORKING. SERVICE DEPARTMENT OF MY SELLING DEALER KEPT THE VEHICLE OVERNIGHT AND FOUND OUT SOMETHING IS BROKEN AND THE BROKEN PART HAS TO BE REPLACED. THEY SAID IT WOULD BE GOING TO TAKE AT LEAST END OF JANUARY 2014(THIS IS WHAT THEY TOLD VERBALLY). NEITHER SERVICE DEPARTMENT OF THE SELLING DEALER NOR THE MANUFACTURER, GUARANTEE WHEN IT CAN FIX AND REFUSED TO PROVIDE DOCUMENT EVIDENCE ON THAT. RIGHT NOW 2014 BMW X5S ARE ON THE ROAD WITHOUT HAVING THE REPLACEMENT PARTS TO FIX IN CASE OF ISSUES. IN MY CASE IT IS HEATED STEERING WHEEL, BUT I'M NOT SURE THE ELECTRONICS OF THIS VEHICLE SINCE IT HAS BROKEN SO NEW AND IT IS TAKING LONGER TIME TO FIX WHICH NOBODY KNOWS WHEN. WHAT I BELIEVE IS MANUFACTURERS SHOULD NOT RELEASE THEIR VEHICLES, UNLESS THEY HAVE FULL CONTROL ON THEIR PRODUCTION LINES. ALSO I ASK DOCUMENT EVIDENCE FROM MANUFACTURER AND SELLING DEALERS SERVICE DEPARTMENT, BY CONFIRMING THAT THIS VEHICLE IS SAFE TO DRIVE. THEY ARE REFUSING TO PROVIDE SUCH DOCUMENT. I REALLY DOUBT THAT 2014 BMW X5S ARE STILL GOOD ENOUGH TO HIT THE ROAD. BTW, THE VEHICLE IS STILL ON TEMPORARY TAGS. SINCE THE VEHICLE WAS SO NEW WHEN IT BROKE AND THE TIME IT IS GOING TO FIX IT IS A UNCERTAIN, I FEEL REALLY UNSAFE ON THIS VEHICLES APPRECIATE IF YOU COULD INVESTIGATE THIS. THANK YOU. *TR
