Infiniti QX50 Reliability by YearBest & worst years, problems & recalls — NHTSA data

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. THEY CANNOT SAY WHY HANDLE SENSOR AND LOCK QUIT WORKING EVEN AFTER RUNNING DIAGNOSTICS. MY GUESS IS THAT SINCE BOTH SIDES AREN'T WORKING, IT IS UNLIKELY THAT THE PROBLEM IS WITH THE SENSOR AS BOTH SIDES WOULD HAVE HAD TO FAIL AT THE SAME TIME EACH TIME. *LN*JB

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.

TL* THE CONTACT OWNS A 2017 INFINITY QX50. WHILE DRIVING APPROXIMATELY 45 MPH AND ATTEMPTING TO STOP, THE VEHICLE DID NOT IMMEDIATELY STOP WHEN DEPRESSING THE BRAKE PEDAL. AS A RESULT, A CRASH ALMOST OCCURRED. THE CONTACT INDICATED THAT THE FAILURE OCCURRED ON MULTIPLE OCCASIONS. THE VEHICLE WAS TAKEN TO RAMSEY INFINITI IN RAMSEY, NEW JERSEY, BUT THE FAILURE COULD NOT BE DUPLICATED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 2,500.

Vehicle screens repeatedly rebooting over a 2 month period. Auto high beams stopped working. Chassis control error on dash occurred. Smoke smell in cabin occurred after dealer returned the vehicle from a repair attempt. Vehicle had to be towed back up . Dealer reporting they can not recreate errors and want to return it. It’s a safety hazard . Has been at the mechanics for over 20 business days. Dealer being unprofessional and swearing at the customer. Vehicle reported crash detection to emergency services in its own when sitting in a fast food drive through.

Engine bearing failures, sudden loss of power, stalling, or complete engine failure — creating crash risks.

The system falsely beeps and displays collision alerts even when no vehicles or objects are present. The system has also initiated braking on the highway with no obstacle present, which is a major safety concern for me and for other drivers. Conversely, when an actual vehicle approached too closely, the system failed to alert or respond at all.

Component/system that failed: Panoramic sunroof glass on a 2023 Infiniti QX50. Date of Incident: July 21, 2025 at approximately 8am. Incident description: While my daughter was driving on the interstate at normal speed, the panoramic sunroof suddenly and spontaneously shattered. There was no impact, no visible object, and no warning. The explosion of glass was loud and violent. Safety risk: Thankfully, the sunroof shade was closed at the time of the incident. Had it been open, glass would have rained down inside the cabin, potentially causing serious or even fatal injuries. This was a terrifying failure with high risk to life and safety, particularly at highway speeds. Immediately after the incident I called Infiniti of Memphis where we purchased the vehicle brand new, and it is currently under warranty. I was notified that since there isn’t a current recall anything glass related is not included under warranty and I would need to file a claim under my insurance. We were forced to file a claim through our insurance provider to repair the damage — despite no fault on our part. Warning signs or prior symptoms: There were no warning lights, no abnormal sounds, and no signs of weakness or cracking. The glass failed without warning. Cause: UNKNOWN — but based on public reports, thousands of similar incidents have occurred in other Infiniti and Nissan models. This appears to be part of a known manufacturer defect currently involved in active class-action litigation (Johnson v. Nissan North America) regarding spontaneous sunroof explosions.

Vehicle is prone to stalling while on the road extremely dangerous starting issues after long trips
