NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2017 Infiniti QX50. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
The contact owns a 2017 Infiniti QX50. The contact stated that while driving at an undisclosed speed, the passenger’s side air bag sensor unexpectedly illuminated and failed to turn off. The vehicle was taken to the dealer, where it was diagnosed, and determined that the passenger’s side seat cushion had failed and needed to be replaced. The vehicle was repaired. The vehicle was later taken to an independent mechanic, who provided the same diagnosis and informed the contact that the passenger’s seat cushion needed to be replaced. The vehicle was repaired. The contact expressed concerns regarding the significant price difference between the dealer's repair cost and the estimate from the independent mechanic. The contact’s spouse was concerned that the failure made the vehicle hazardous to drive. The manufacturer was made aware of the failure. The approximate failure mileage was 89,000.
Engine shut off while driving 45mph with no prior warning
Engine light is on - transmission output speed sensor. Vehicle was inspect by Pep Boys # 208 My vehicle don't want to pick up speed. I don't know what caused the problem.
Last year I had to have the BCM replaced on my infiniti. Here I am a year later and I'm being told that I have to replace the BCM again. The dealer told me that there's water that is literally streaming directly past the module due to the drainage coming from the sunroof. I have no idea why that I happening bring I haven't experienced any leakage from the sunroof. I definitely shouldn't have to replace a BCM 1 year after installation of a new module. Please take look into this issue. I just don't think it's fair that I have to replace another BCM due to the drainage ststem/path on such a luxurious car.
Airbag light came on. Diagnosed by Infinity as code B00AO-02 which requires replacing the Passenger Front Seat Bottom Assembly at the cost estimate of $9871.82 (date of estimate is 1/27/23) according to Infinity. Ethos extended warranty will not cover the issue as well as Infinity. Interesting info: Ethos did cover did not cover this particular make/model. However, after Infinity changed manufacture for above said problem, Ethos now covers the SRS problem described above in their extended warranty. This leads me to the suspicion that 'maybe' Infinity was aware of the problem since they changed manufacturer. THIS IS A CRITICAL SAFETY ISSUE! Mileage on the vehicle on 1/27/23 was 9,665 miles. This car is immaculate, never wrecked always garage kept, driven my 86 year old widow. The car is a so called 'high end' luxury vehicle with a sub-par SRS system.

SENSOR ON MY HANDLE AND THE KEY QUIT WORKING OVER THIS PAST YEAR MY CAR HAS BEEN AT THE SERVICE DEPARTMENT FOR DAYS AND WEEKS AT A TIME FOR THE SAME ISSUE DEALERSHIP HAS CHECK ALL SETTING THEY HAVE CHANGED THE BATTER THREE TIMES IN THE CAR AND TWICE IN THEY HAVE CHANGED THE BATTERY IN THE REMOTE , I'M NOW TOLD THAT THEY JUST CHANGED THE DOOR HANDLE AND WAS TOLD THERE IS NOTHING THEY CAN DO ABOUT IT, AND WAS ASKED TO PICK UP THE CAR , I STRESSED THAT I WILL BE OUT OF WARRANTY AND I DON'T WANT TO HAVE THIS SAME PROBLEM HEN ITS EXPIRED OR TRANSFER OR SELL TO SOMEONE ELSE TO INHERIT THIS ISSUE. PLEASE NOTE ,THE PUSH BUTTON ON THE HANDLE DO NOT WORK ON THE PASSENGER SIDE, AND THE PUSH BUTTON DO NOT WORK ON THE HANDLE ON THE DRIVER SIDE THIS WOULD HAPPEN RANDOMLY EACH TIME I HAVE TAKEN MY CAR QX50 TO THE DEALER FOR SERVICE ATTENTION I WAS TOLD THEY WILL NEED TO SEE THE ISSUE SO I PROVIDED THEM WITH THE VIDEO , THIS LAST TIME THEY SEEN IT THEMSELVES AND DECIDED TO HOLD ONTO THE FOR FURTHER RESEARCH , THIS IS WHEN I WAS ASKED TO PICK UP THE CAR IN ITS CONDITION.

THE CAR DRIFTS ALL OVER THE HIGHWAY AT NORMAL HIGHWAY SPEEDS. IT IS AS IF I AM ALWAYS FIGHTING A STRONG WIND. IT IS VERY DISTRACTING AND DANGEROUS. SEEMS LIKE ANYTHING OVER 60MPH IS VERY CHALLENGING TO KEEP BETWEEN THE LINES. I TOOK IT TO THE DEALER ON 2/01/2020 AND WAS TOLD THAT THIS IS NORMAL FOR THESE SPORTS SUV'S. THEY ALL DO IT. VERY DISCOURAGING. THIS WAS NOTICED ABOUT 10,000 MILES AGO AND SEEMS TO BE GETTING WORSE. THE CAR HAS 43,000 NOW
I WAS DRIVING ON THE GARDEN STATE PARKWAY NORTHBOUND ON THE NEW YORK EXTENSION IN THE EVENING OF MARCH 24TH AT APPROXIMATELY 7:40 PM AT APPROXIMATELY 65 MPH WHEN OUT OF NOWHERE MY MOON ROOF EXPLODED. THERE WAS ABSOLUTELY NO OVERPASS REMOTELY NEAR WHERE THIS OCCURRED. THERE WAS NO OTHER DAMAGE ON THE CAR FORWARD OF THE MOON ROOF AND NO DAMAGE PAST IT ASIDE FROM SCRATCHING CAUSED BY GLASS ON THE ROOF AND REAR SPOILER. THERE WAS NO OBJECT THAT IMPACTED THE VEHICLE IN ANY WAY SHAPE OR FORM. BASED ON THE ATTACHED PHOTOS THE GLASS IS PROTRUDING FROM THE ROOF PANEL AS IF IT EXPLODED OUTWARD. THERE IS GLASS RESIDUE ON THE MOON ROOF COVER WHICH INDICATES THAT THE COVER WAS CLOSED AT THE TIME OF THE INCIDENT. FURTHERMORE IF THE COVER WASN'T IN PLACE THE GLASS WOULD HAVE RAINED DOWN INTO THE CABIN AND COULD HAVE HAD SIGNIFICANTLY INJURED MYSELF.
