Bmw
M4

Filled car with gas and drove home , came out 10 minutes later to a puddle of fuel under car , from the fuel tank on the rear driver side

Both front steering bearing carriers (knuckles) cracked... this is a well documented defect on the M4 GTS model that BMW has not addressed.

The car only has 500 miles. It is a show car not taken out of the garage. Went to change oil and inspection sticker. Found to have a bad front knuckle. It is cracked. Many forums on this. This car is limited and has very low miles by owners. This should not be occurring

THE BILLET ALUMINUM STEERING KNUCKLES/STEERING CARRIERS ARE CRACKED AT ONE OF TWO BOLT POINTS CAUSING A SIGNIFICANT SAFETY CONCERN. THIS IS A KNOWN MANUFACTURER DEFECT AND BMW SUBSEQUENTLY CHANGED THE DESIGN OF THE REPLACEMENT PART. THIS BILLET ALUMINUM PART IS SPECIFIC TO THE 2016 BMW M4 GTS, A LIMITED EDITION BMW M4. APPROXIMATELY 800 M4 GTS'S WERE EVER BUILT AND THESE PARTS ARE FAILING AT ALL MILEAGE VALUES. THIS ISSUE IS WELL DOCUMENTED ON BIMMERPOST.COM FROM SEVERAL OWNERS. BMW WILL NOT COVER THE COST TO REPLACE IF THE VEHICLE IS OUTSIDE OF THE WARRANTY, REGARDLESS OF THE MILEAGE; MINE HAS 6,500 MILES. IF THE SECOND BOLT FAILS, THE COMPONENT WILL NO LONGER BE ATTACHED TO THE STRUT AND CAUSE CATASTROPHIC DAMAGE TO THE VEHICLE, PERSONAL INJURY AND POTENTIALLY DEATH. I NOTIFIED BMW AND THEY DENIED THE CLAIM AFTER 4 WEEKS OF REVIEW WITHOUT ANY REASON.

DIAGNOSED WITH COOLING SYSTEM ISSUE, 2ND COOLING SYSTEM DRY/LOW OR LEAKING, TRANSMISSION ISSUE, CODE 537, POWER TRAIN ISSUE, CAR IS QUICK SHIFTING AND SKIPPING FROM 5TH TO 7TH GEAR WITH A BUZZING SOUND, AND WITHOUT A DROP IN POWER. THE CAR ONLY HAS 48,000 MILES. WE BOUGHT THIS CAR 5 MONTHS AGO FROM A MERCEDES BENZ DEALERSHIP IN TYLER, TEXAS. IT SHOWS ON THIS SIGHT THAT THERE'S 3 RECALLS.

THE CRANK HUB ON THIS VEHICLE CAN SPUN AND BRAKE INSIDE THE ENGINE WITHOUT ANY WARNING, IF THAT HAPPENS ON A HWY FOR EXAMPLE THE VEHICLE WILL COMPLETELY LOOSE POWER AND I CAN BE INVOLVED IN A ACCIDENT WHICH MAYBE FATAL.

CRANK HUB SPINS, ITS SOMETHING THAT BMW MANUFACTURE SHOULD RECALL AND FIX BECAUSE IT CAN DAMAGE YOUR WHOLE ENGINE.

BMW IS AWARE OF A CRACK DEVELOPING IN A FRONT SUSPENSION CARRIER (ONE EACH LOCATED ON BOTH THE DRIVER'S SIDE AND PASSENGER'S SIDE - TWO TOTAL). BMW HAD TO REPLACE MY PASSENGER SIDE CARRIER UNDER WARRANTY. WHEN I TOOK MY CAR IN FOR AN OIL CHANGE, THE SERVICE TECHNICIAN DETECTED A HAIRLINE CRACK AND ORDERED THE REPLACEMENT PART FROM GERMANY. I DID NOT ASK FOR THE PART TO BE INSPECTED; IT SEEMS THAT BMW HAS INSTRUCTED ITS SERVICE CENTERS TO INSPECT VEHICLES FOR THIS PARTICULAR FAILURE. I ASKED THE SERVICE CENTER TO PROACTIVELY REPLACE THE DRIVER'S SIDE CARRIER, TOO. THEY REFUSED TO DO SO. THE ISSUE WITH CRACKS DEVELOPING IN THE FRONT TWO CARRIERS IS WELL DOCUMENTED (SEE, FOR EXAMPLE: HTTPS://F80.BIMMERPOST.COM/FORUMS/SHOWTHREAD.PHP?T=1550724). I HAVE ATTACHED A COPY OF THE SERVICE RECORD SHOWING REPLACEMENT OF MY PASSENGER SIDE CARRIER. I HAVE ALSO ATTACHED TWO IMAGES SHOWING CRACKS ON THE PART FROM THE LINK PROVIDED ABOVE. I BELIEVE THAT BMW SHOULD BE REQUIRED TO REPLACE THE CARRIERS ON ALL CARS GIVEN THE POSSIBILITY OF FAILURE AND THE KNOWN FAILURE FREQUENCY.
