2019 Infiniti QX50 Recall Campaign ID: R25B2 (Safety Recall 2025) Summary of Issue: I received a safety recall notice stating that my vehicle may have an engine manufacturing defect that could cause severe damage or complete engine failure. This poses a significant safety risk. Details: Contacted Infiniti Consumer Affairs on August 28, 2025 (Case #55702324) and my local dealer. Dealer confirmed recall is active but remedy is not available; they refused inspection even if I offered to pay. Consumer Affairs indicated proactive assessment may incur charges unless defect is confirmed, which I find unreasonable given the severity of the issue. No timeline provided for remedy or inspection. No alternative transportation offered. Safety Concern: Driving the vehicle under these conditions could lead to sudden engine failure, increasing risk of accidents and injury. Requested Action: Confirm recall status and remedy timeline. Require manufacturer to provide inspection or alternative transportation until repairs are available.
Me han enviado un recall el cual me enviaron en fecha 22 de octubre del presente año y lo he recibido hace unos dos días. He ido a infinito service y me informaron que el recall había sido retirado. Mi carro ha estado presentando problemas con el motor y todo lo que describe en el recall ya lo está presentando. Cómo es posible que el recall se haya retira? El problema existe, necesito que me habiliten esto, mi carro puede presentar problemas más graves y ustedes se tendrán que hacer responsables. Ya ha tenido pérdida de potencias y los demás síntomas
The Drive Unit Power Back Door. Part Number: 90560-5NA0B has failed and causes a severe risk of injury when trying to access the cargo area. The lift gate rises up and abruptly descends causing a hazardous situation to the consumer. This is a premature failure for a 4 year old car and has a very high cost to repair. The lift gate is very heavy and could cause severe injury if a person is struck by it while it is rapidly moving in a downward direction. It will not stay up and the “safety” feature is not functional.
BACK IN JUNE 2019 WHEN THIS VEHICLE HAD ABOUT 5000 MILES, I BEGAN TO FEEL SHORTNESS OF BREATH AND LIGHT HEADEDNESS, UNTIL ONE DAY WHILE DRIVING HOME ON A VERY HOT DAY, I BEGAN TO LOSE CONSCIOUSNESS WHILE DRIVING. I TOOK THE CAR TO INFINITI AND EVEN AFTER 60 DAYS, THEY HAD NO CLUE WHAT WAS GOING ON. THEY CALLED ONE OF THEIR ENGINEERS WHO RECOMMENDED AN INDOOR AIR QUALITY TEST WHICH WAS IGNORED AND NEVER PERFORMED. LATE FEBRUARY 2020, I BEGAN A LEMON LAWSUIT. THEN IN AUGUST 2020, I HAD TO PAY OUT OF POCKET FOR THAT TEST AND WAS ABLE TO PROVE THAT THE CAR HAD A CO2 ISSUE THAT CAUSED ME TO NEARLY GO UNCONSCIOUS A FEW TIMES, AND RESULTED IN SEVERAL MONTHS OF SEVERE MIGRAINES AND DIZZINESS WHICH CAUSED ME TO BE OUT OF WORK AND LOSS OF WAGES. MY HUSBAND ALSO DROVE THE CAR FOR A WEEK AND BEGAN TO EXPERIENCE HEADACHES. THIS WAS AFTER THEY CHANGED THE EVAP HOSE LINE EVEN THOUGH I NEVER SMELLED GAS. I HAVEN'T BEEN ABLE TO DRIVE IT SINCE DECEMBER 2019 AND AM FORCED TO KEEP PAYING FOR IT WHILE THE LEMON LAW SUIT PROCESS GOES ON. THANKS TO COVID, THIS HAS BEEN GOING ON FOR ALMOST A YEAR NOW WITH NO END IN SIGHT. INFINITI WAS MADE AWARE OF THE CO2 ISSUES IN AUGUST 2020 AND ONLY NOW IN FEBRUARY 2021 IS WHEN THEY HAVE ASKED TO BRING IN THE CAR TO ATTEMPT TO FIX THE ISSUE. I ALSO EXPERIENCED ISSUES WITH THE CAR SUDDENLY BREAKING WHILE DRIVING ON THE HIGHWAY AND NO CARS IN FRONT OR NEAR ME, AND CAMERAS TURNING ON FOR NO REASON. THIS WAS MY 6TH NISSAN INFINITI SINCE 2004, AND I WILL NEVER DO BUSINESS WITH THEM AGAIN.
