2019 BMW X4 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

WHILE DRIVING, COLLISION DETECTION ACTIVATES FOR NO REASON. VERY RANDOM, SOMETIMES JUST WARNING LIGHTS AND SOUNDS, AND SOMETIMES SLAMMING ON BRAKES AT SPEED OVER 40 MPH. NO CARS COMING IN OTHER DIRECTION OR ANY OBSTACLES WHATSOEVER. WEATHER CLEAR. I ALMOST GOT REAR-ENDED ONCE. DID NOT ACTIVATE WHEN FOX RAN IN FRONT OF CAR. I CAN GO WEEKS WITHOUT THIS HAPPENING AND THEN IT COMES OUT OF THE BLUE. IT'S IN THE SHOP FOR THE THIRD TIME FOR THIS COMPLAINT AND SERVICE SAYS THEY HAVE NO "ERROR CODES" AND CAN'T RECREATE THE PROBLEM. BMWUSA TOLD SERVICE TO TRY TO RECREATE THE PROBLEM BY DRIVING IT OVERNIGHT. THERE'S A 50/50 CHANCE IT WILL HAPPEN WHEN THEY DRIVE IT, AND THERE STILL WON'T BE ERROR CODES! BMW WON'T AUTHORIZE ANY REPAIR UNTIL THEY GO THROUGH THESE STEPS. THIS HAS BEEN ON AND OFF FOR AT LEAST 6 MONTHS. DATE BELOW WAS MOST RECENT OCCURRENCE. OBVIOUSLY, OBTAINING ANY DOCUMENTATION OF PROOF IS IMPOSSIBLE UNLESS I HAVE A CAMERA CREW ON ME ALL THE TIME. IT'S TERRIFYING AND DANGEROUS!

I JUST GOT MY CAR 3 DAYS AGO. MILEAGE IS 275 MILES. MY REAR BRAKES DISC ALREADY HAVE CIRCLES IN IT AS IF IT IS WORN OUT BY A PIECE OF METAL GRINDING AGAINST IT. THIS HAS NEVER EVER HAPPENED ON ANY OF MY PREVIOUS BMWS. THIS USUALLY HAPPENS ONLY WHEN THE BRAKES ARE WORN OUT AND PROCRASTINATING NOT TO FIX IT. WHY DOES THIS HAPPEN TO A BRAND NEW CAR????

TL* THE CONTACT OWNS A 2019 BMW X4. THE CONTACT STATED THAT THE DRIVER ASSISTANCE PACKAGE FAILED AND THE WARNING VIBRATION WHEN THE CONTACT ALMOST CRASHED. THE SYSTEM WAS SUPPOSED TO VIBRATE WHEN AND IF THE CONTACT WAS ABOUT TO CRASH. THE CONTACT STATED THAT THE PACKAGE VIBRATION SIGNAL WAS VERY LOW AND THE CONTACT COULD NOT FEEL IT ACTIVATE. THE VEHICLE WAS DRIVEN TO KRITZ BMW SAVANNAH (7009 ABERCORN ST, SAVANNAH, GA 31406, (912) 354-7000) WHERE IT WAS DIAGNOSED THAT A NEW VIBRATION MOTOR AND COMPUTER UPDATE WERE NEEDED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THEY WOULD ESCALATE THE INCIDENT. THE FAILURE MILEAGE WAS 2,321. *BF THE CAR WAS ROAD TESTED AFTER REPAIR. DEALER REPAIRMEN STATED CONTACTS VEHICLE AND OTHER X 4'S ON THE LOT PERFORMED THE SAME. CONTACT STATED THAT THE "REPAIRS" DID NOT IMPROVE VIBRATION WARNING EVEN WHEN SET ON "STRONG" A VIBRATION THAT CAN ONLY BE FELT ON A SMOOTH ROAD WHEN THE DRIVER PURPOSELY CROSSES THE LANE MARKINGS IS NOT A "WARNING" AND IS UNSAFE. THE ESSENCE OF MY COMPLAINT IS THAT THE LANE DEPARTURE SYSTEM WHILE "WORKING" IS NOT PROVIDING A STRONG VIBRATION THAT SERVES AS A WARNING. THE DEALER STATES MY VIBRATION MATCHES OTHERX4S AND IS THEREFORE REPAIRED. I FEEL ALL X4S ARE NO NOT PERFORMING AS DESIGNED AND ARE THEREFORE A SAFETY HAZZARD. I PURCHASED THIS CAR WITH THIS SPECIFIC FEATURE TO ASSIST MY DRIVING SHOULD I DRIFT INTO THE ON COMING LANE WITHOUT A SUFFICIENT VIBRATION (WARNING) I FEEL THE CAR IS DANGEROUS AND SOMEDAY THERE WILL BE ACCIDENTS DUE TO THIS MISS REPRESENTATION. MY LAST CAR, A 2017 MERCEDES HAD A GREAT LANE DEPARTURE SYSTEM THAT REALLY WARNED WITHOUT A POSITIVE WARNING! THE DRIVER BMW HAS SOME HOW RELEASED THIS NEWLY DESIGNED MODEL.*JB

ON MAY 03, 2019, I BOUGHT A 2019 BMW X4 M40I, AT BRAMAN MOTORCARS. THIS IS NOT MY FIRST BMW, WE HAVE 3 MORE BMWS AT HOME. UNFORTUNATELY, THIS BMW X4 VEHICLE HAS NOT PERFORMED WELL AS EXPECTED! ON MAY 27, 2020 I WAS DRIVING WHILE IT WAS RAINING WHEN THE CAR SUDDENLY STOPPED AND NEVER TURNED ON AGAIN, IT WAS COMPLETELY USELESS AND VERY DISSATISFYING. I AM VERY FRUSTRATED AND DISAPPOINTED BECAUSE I SENT THE CAR TO BRAMAN BMW SERVICE CENTER TO CHECK IT OUT AND REQUEST THE WARRANTY AND THEY SAID THAT THE WARRANTY DOES NOT COVER IT THE SOLUTION IS JUST TO PAY MORE THAN $30,000.00 IN REPAIR PLUS PARKING FEES. ALSO, MY INSURANCE CARRIER SAID MY POLICY DOES NOT COVER MECHANICAL ISSUES. ALSE SENT A LETTER ASKING FOR HELP TO BMW CEO AND THEY RESPONDED THAT THE WARRANTY DO NOT COVER " OUTSIDE INFLUENCES". SO THIS GRABAGES CAR CANT BE IN A RAIN. SO NOW I HAVE MORE THAN 1 AND HALF MONTHS WITHOUT THE CAR, ALSO CALLED BMW FINANCIAL SERVICES FOR HELP AND THE SOLUTION WAS THAT I CAN RETURN THE CAR SIGNING A VOLUNTARY REPO DAMAGING MY CREDIT HISTORY. ATTACHED TO THIS EMAIL YOU WILL FIND COPIES OF THE DENIAL OF THE WARRANTY AND THE ESTIMATE THAT BRAMAN BMW SENT ME, TO REPAIR THE CAR, WHICH BY THE WAY IS ABSURD! WAITING FOR YOU HELP, [XXX] REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *CC

report

as I was driving, the gas fuel line started spewing gas all over. The crack was higher up, behind the backseat, had to replace the fuel line. And behind the backseat was soaked with fuel oil. there was a material substance wrapped around like a cloth around the cracked area. As if the crack came from the factory and they covered it up.
