While driving my vehicle with my family, I experienced a sudden and dangerous loss of control. I was able to safely maneuver the vehicle off the roadway without injury. After inspection, it was determined that the subframe had fractured due to severe rust, which was not previously identified. The failure occurred without warning and directly impacted the ability to control the vehicle, creating a significant safety hazard. No warnings or messages indicated a problem existed prior to the failure.
NHTSA complaint #11742803 — an unverified report by a vehicle owner.
A subframe is a key structural component of every car. As such, it stands to reason that it should last as long as the car itself. Doing much research on this model suspension and subframes become rusted as I didn’t know this when purchasing making it very unsafe . I experienced being involved in almost 2 accidents. Very dangerous. Subframe split in half and suspension. Something needs to be done as a lot of people are going thru this issue and Infiniti slogan claims “new horizons” by no means new horizon going to heaven by driving their vehicles.
NHTSA complaint #11606665 — an unverified report by a vehicle owner.
While driving at highway speed, rear of vehicle suddenly became uncontrolled and caused vehicle to swerve dangerously. If a vehicle would have been in the adjacent lane an accident would have occurred. Upon initial inspection, the left rear lower control arm failed catastrophically due to rust rendering the vehicle undrivable. Driver and passenger were put at risk as a result of this incident. Deeper inspection revealed the right rear control arm was also compromised due to rust as well as the two forward mounting points of the modular rear suspension cradle (framework). No warning lights appeared, however the steering wheel did begin correcting to the right just prior to event, similar to heavy wind situation. Parts have not been inspected by manufacturer. Pictures attached. Parts are available for inspection upon request.

The rear controls arms and cradle mount were riddled with severe fissures, causing car to sway dramatically. The level of component failure posed a severe safety risk to me. My mechanic was shocked by the amount of failure to these major rear suspension components. I have included photos and receipts for repairs.

The contact owns a 2013 Infiniti QX56. The contact stated that intermittently while parked, and while driving at various speeds, the rear of the vehicle was sagging. No warning lights were illuminated. The vehicle was taken to a local dealer, where it was diagnosed that the air shocks and compressor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and the contact was informed that the warranty had expired. The approximate failure mileage was 40,000. The contact stated that the air suspension system on the vehicle never properly worked. There was an attempt to make repairs but that did not fix the problem.

NHTSA complaint #11473908 — an unverified report by a vehicle owner.
While my wife was driving our QX56 during normal conditions at approximately 40MPH, QX56 begun to swerve repeatedly left to right in a dangerous manner and she had to apply brakes rapidly. Looking under the vehicle, the lower control arm was badly cracked and the cause of the swerving. I towed to my local shop (not Infiniti dealership) for repair and they confirmed the right control arm was cracked. They stated the left control arm was also severely rusted / damaged and wasn't too far from cracking either. Fortunately, my wife was only going 40mph and was able to control the swerving. If going 70 or 75MPH on the highway, I'm not sure that would have been possible. Pictures are attached, both of broken right control arm which caused swerving and left control arm that is near cracking. With both control arms going out at same time, I feel this is a dangerous, quality control issue from Infiniti. I spoke with Seth at Infiniti Consumer affairs who stated they wouldn't reimburse the repair at a non-Infiniti repair show and didn't appear to plan to pass on the seriousness of the problem.

NHTSA complaint #11378309 — an unverified report by a vehicle owner.
TIMING CHAIN STARTED RATTLING @ 125,000 MILES.. HOWEVER, MY VIN SHOWS NO RECALL FOR MY CAR. CATS WENT BAD, HAD TO BE REPLACED AND NOW NEED TO BE REPLACED AGAIN. YET NO RECALL ON MY CAR. THE BATTERY CONSTANTLY GOES DEAD IN THE CAR. I BOUGHT A NEW INFINITY BATTERY IN THE CAR THE SAME THING HAPPENED. YOU CAN REPRODUCE THIS PROBLEM BY SITTING IN THE CAR LISTENING TO THE RADIO FOR 30 MINUTES. I WAS SITTING IN THE CAR LISTENING RADIO AND THE CAR BATTERY WENT DEAD AND THE CAR SHUT OFF. THIS IS A HUGE ISSUE, THE QX56 IS A 8 CYLINDER CAR. IT DOES NOT CHARGE VERY EASILY. I HAVE TO CARRY A BATTERY CHARGER IN MY CAR. I HAVE BEEN STRANDED SEVERAL TIMES IN THE LAST YEAR. I HAVE TAKEN THE CAR TO INFINITY AND THEY CLAIM NOTHING IS WRONG WITH THE CAR. SINCE IT IS A BIG CAR THE BATTERY DRAIN QUICKLY.

I PURCHASED MY 2011 INFINITI QX56IN JANUARY OF 2015 WITH 36,6036 MILES ON IT. I TAKE EXCELLENT CARE OF MY VEHICLE MECHANICALLY AND CLEANLINESS. ON AUGUST 17TH, 2019 MY BACK A FRAME AND OTHER REAR SUSPENSION BROKE DUE TO CORROSION AND THE METAL SPLIT APART. MY UNDER CARRIAGE ALSO LOOKS LIKE AND OLD CAR. MY CAR IS WASHED TWICE A WEEK EVEN IN THE WINTER TO REMOVE THE SALT. THIS IS NOT COVERED UNDER ANY OF MY WARRANTIES. IT IS GOING TO COST ME $5,200.00 TO MAKE THIS REPAIR. I HAD TWO CHEVY SUBURBANS THAT I PUT 295,000 MILES ON AND SOLD THEM TO FRIENDS AND THEY ARE STILL DRIVING THEM WITH NO ISSUES LIKE THIS. I WILL NEVER BUY A INFINITI AGAIN! I NOTICED THIS WHEN I WAS APPROACHING THE BACK OF MY VEHICLE AFTER PLAYING HOCKEY. SO IT MUST HAVE HAPPENED AFTER I PARKED THE CAR.

NHTSA complaint #11190228 — an unverified report by a vehicle owner.
MY 2012 INFINITI QX56 WITH HBMC DRIVES VERY TWITCHY AND FEELS UNSAFE TO DRIVE. IT HADLES WELL ON PERFECTLY SMOOTH ROADS BUT IF THERE ARE ANY IMPERFECTIONS IT TRIES TO JUMP BACK AND FORTH IN THE LANE. I HAVE HAD THE WHEELS BALANCED AND ALIGNMENT PERFORMED AT THE LOCAL NISSAN DEALER BUT THIS HAS NOT HELPED THE DRIVING CHARACTERISTICS. IF I AM COMING INTO A CORNER TOO FAST THE BACK END WILL SKIP ABOUT AS IF THE REAR ALIGNMENT IS OUT OF WHACK. I AM NOT SURE IF THIS HAS TO DO WITH THE 22" WHEELS BEING TOO HEAVY OR THE DRIVE BY WIRE BEING CALIBRATED TO SENSITIVE OR IF THERE IS SOMETHING WRONG WITH THE SUSPENSION THE DEALER IS NOT SPOTTING. I FEEL LIKE I WANT TO TRADE THE CAR IN AFTER ONLY 4 MONTHS AND 8,000 MILES OF DRIVING IT.
NHTSA complaint #11142909 — an unverified report by a vehicle owner.
MY 2009 INFINITI QX56 HAS A SERIOUS ISSUE WITH THE REAR SUSPENSION THAT STARTED ABOUT A YEAR AFTER I GOT THE CAR WHEN IT WAS AT ABOUT 100,000 MILES AND HAS GOTTEN WORSE, EVEN THOUGH REPAIR SHOPS AND DEALER KEEP TELLING ME IT'S 'FINE'... WHEN TRAVELING DOWN THE HIGHWAY AT SPEEDS OVER 50MPH, IF I HIT OR DRIVE OVER ANY BUMP OR POTHOLE OR DIP OR UNEVEN PAVEMENT, THE BACKEND OF THE CAR FEELS LIKE IT IS GOING TO FISHTAIL OR SWING OUT OF CONTROL AND HAS GOTTEN WORSE. NOW, AT SLOW SPEEDS WHEN I HIT ANY OF THE AFOREMENTIONED TYPICAL ROAD / PAVEMENT ISSUES, THE BACK END SOUNDS LIKE IT IS SLAMMING DOWN ON ITSELF. ALSO, THE BRAKES NOW SOMETIMES FEEL LIKE THE PEDAL IS "LOOSE" AND GOES NEARLY TO THE FLOOR. IF I PUMP THE BRAKE AGAIN, IT GOES BACK TO NORMAL. I HAVE TAKEN THE VEHICLE IN AND BEEN TOLD THE "BRAKES ARE JUST FINE" AND THEY ACT LIKE THEY DON'T KNOW WHAT I AM TALKING ABOUT. THE SAME WITH THE SUSPENSION, EXCEPT FOR NOW THERE IS A "TINGING" SOUND SOMETIMES UPON STARTING OR ACCELERATING. THE REPAIR SHOP TOLD ME THE STRUTS AND SHOCKS ETC 'ARE FINE', BUT THAT THERE MAY BE AN ISSUE WITH THE SUSPENSION THE DEALER ACTED LIKE THEY DIDN'T KNOW WHAT I WAS TALKING ABOUT, BUT AFTER RESEARCH HERE ... I SEE THAT THIS EXACT PROBLEM IS COMMON WITH THIS VEHICLE AND THE 2011, SUCH THAT THERE IS A RECALL FOR THE MODELS MANUFACTURED NOV. 2009 AND 2010. ALL OF THESE VEHICLES SHOULD BE FIXED BY MANUFACTURER. THEY KNOW THIS IS AN ISSUE AND EVEN RECALLED SOME VEHICLES. THIS TRULY COULD KILL US SOME DAY... BRAKES DON'T WORK OR THE CAR'S BACK-END SWINGS OUT OF THE LANE AND FISHTAILS OUT OF CONTROL ON THE INTERSTATE. IT HAPPENS ALL THE TIME NOW. I RESEARCHED BECAUSE I NEED TO DRIVE MY SON TO COLLEGE AND KNEW IT DIDN'T FEEL SAFE. I FOUND YOU MAY ALREADY BE INVESTIGATING THESE ISSUES AND I WOULD LIKE A RESOLUTION AND TO HAVE MY TESTIMONY INCLUDED. IT'S DANGEROUS.

DRIVER SIDE FRONT SUSPENSION SPRING COMPLETELY BROKEN AND COLAPSED LEAVING THE CAR ONLY SUPPORTED BY THE DRIVER ABSORBER SHOCK. THE LEFT FRONT END IS LEANING 2 INCHES LOWER THAN USUAL. I ASSUME THIS A HAZARD AND COULD CAUSE A VEHICLE TO LOOSE CONTROL AND ACCIDENTS.

NHTSA complaint #10985139 — an unverified report by a vehicle owner.
