2007 BMW 335I Power Train Problems

NORMAL USE OF DS SPORT MODE INVOLVED MOVING THE AUTOMATIC TRANSMISSION SHIFTER TO THE LEFT. THIS PUTS TENSION ON THE WIRES THAT SUPPORT THIS FUNCTION, CRIMPING THE WIRES AND FREQUENTLY LEADING TO FAILURE. THE PROBLEM APPEARS TO BE WITH THE WAY THE WIRING HARNESS IS ROUTED WITHIN THE TRANSMISSION LEVER. THIS IS DOCUMENTED AS A FREQUENT OCCURRENCE IN NUMEROUS DIY VIDEOS ON YOUTUBE AND INTERNET FORUMS. FAILURE OF DS SPORT MODE MEANS THAT CAR CAN NO LONGER BE USED IN THIS MODE. HOWEVER, IT CAN BE DRIVEN IN NORMAL MODE. THIS DOES NOT APPEAR TO BE A SAFETY ISSUE. IT IS A DESIGN FLAW THAT, THROUGH NORMAL USE, RESULTS IN A FAILURE THAT MAY REQUIRE AN EXPENSIVE REPAIR. MY LOCAL SHOP QUOTED ME $1,500 TO REPLACE THE SHIFTER.

THE TRANSMISSION MALFUNCTIONED WHILE ATTEMPTING TO PARK. CAR WON'T GO IN REVERSE, ALSO CAR HAD NO POWER TO ACCELERATE IN DRIVE MODE. THIS WAS CAUSED BECAUSE THE VALVE BODY SEALING SLEEVE THAT IS MADE OF PLASTIC BROKE.

THE CAR HAS HAD NUMEROUS ISSUES SINCE PURCHASED. THIS ALL CAME TO A HEAD WHEN DRIVING HOME, UNDER NORMAL CONDITIONS, IT SUDDENLY WOULD NOT SHIFT PAST 1ST GEAR. I PROCEEDED TO PULL OFF TO A SIDE STREET AND ATTEMPT TO IDLE HOME, AS I WAS ABOUT 1 MILE FROM HOME. AFTER APPROXIMATELY .5 MILE, THE TRANSMISSION SUDDENLY LOST FIRST GEAR, THERE WAS AN AUDIBLE BANG UNDER THE HOOD, AND THE CAR COMPLETELY LOST POWER. AFTER BEING IN A SERVICE CENTER FOR A COUPLE WEEKS, I AM NOW INFORMED THAT THE ENGINE IS LOCKED DOWN AND THAT THE CAR WILL REQUIRE A NEW ENGINE TO BE WORKING AGAIN. THIS CAR HAD BEEN AN ABSOLUTE NIGHTMARE AND HAS TURNED ME QUITE CALLOUSED TOWARDS BMWS QUALITY STANDARDS.

VALVE COVER OIL LEAKING ONTO EXHAUST MANIFOLD THAT CAUSES FIRE. IT WAS TURNED OFF AND STATIONARY. ASKED BMW TO CHANGE IN 80K BUT THEY SAID JUST SWEATING OIL. SAFETY HAZARD IGNORED. COMMON AMOUNG BMW 3 SERIES ENGINE

THERE IS A SERIOUS DEFECT WITH THE ENGINE AND FUEL PUMP. IT TAKES A LONG TIME TO ACCELERATE WHEN DRIVING ESPECIALLY ON THE HIGHWAY, THE CAR WILL SHAKE, JOLT AND THE ENGINE WILL START TO MAKE A WEIRD NOISE. THERE IS OIL LEAKING CONSTANTLY AND THE CHECK ENGINE LIGHT IS CONSTANTLY COMING ON EVEN AFTER JUST BEING REPAIRED. THE CAR GOES INTO LIMP MODE AND HAS SHUT DOWN ON ME NUMEROUS TIMES WHILE DRIVING. I'VE HAD THE FUEL PUMP REPLACED NUMEROUS TIMES AND YET IT NEEDS TO BE REPLACED AGAINST. THE CAR WILL OVERHEAT AT TIMES AND AND JUST SHUT DOWN. I WAS DRIVING ON A BUSY CITY STREET WHEN THE CAR JUST SHUT DOWN, I COULDN'T STEER OR BRAKE IT JUST DIED IN THE MIDDLE OF A BUSY STREET. IT WAS EXTREMELY UNSAFE AND PUT MY LIFE IN DANGER AS WELL AS THE OTHER DRIVERS ON THE ROAD, ESPECIALLY...

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

CAR STALLING AND NO POWER IN THE MIDDLE OF THE ROAD WHILE DRIVING. NO POWER TO ACCELERATE. THIS HAPPENED WHILE I WAS MAKING A U TURN, CARS WAS COMING AT ME AT A HIGH RATE OF SPEED AND I COULDN'T GET POWER TO ACCELERATE. TRIED PULLING OVER SAFELY. CAR WAS OOZING POWER AND CANT RESTART NORMALLY. *TR

WHEN I TRIED TO MAKE A SHARP U TURN ON A HILLSIDE STREET, THE CAR SUDDENLY ACCELERATED, AND STOPPED WITH ITS BELLY STUCK ON THE CURB AND THE REAR WHEELS IN THE AIR AFTER HITTING THE GUARD RAIL ACROSS THE STREET. IT WAS SO SUDDEN, AND THE CAR JUMPED ABOUT 12 FEET INSTANTLY, AND HIT THE RAIL. SINCE THE STREET IS SLOPING DOWN, I NEVER ACCELERATE WHEN I COME DOWN THE HILL. THIS MODEL HAS A TURBO PROBLEM, AND THE WARRANTY IS EXTENDED ON THE TURBO PART UP TO 10 YEARS. THIS CAR HAD A SEVERAL STARTING PROBLEMS BEFORE, AND DISPLAYED THE "CHECK ENGINE" LIGHT. THEN IT IS RESET BY ITSELF. WHEN THE DEALER WAS ASKED, THEY DENIED THE POSSIBILITY OF ANY MALFUNCTION OF THE CAR. THIS SUDDEN ACCELERATION LOOKS LIKE A DEADLY FAILURE. IF IT HAPPENS IN A BUSY INTERSECTION, IT MIGHT HAVE RESULTED IN FATAL CRASHES OR DEATHS...
