Owner report 11495858 · 2022-12-02 (December 2, 2022)
This is the 3rd instance of my car rolling backwards down the driveway. Both the first and second instances of uncontrolled rolling happened in 2016. Only the second instance was caught on camera. I shared the video with Infiniti and was instructed to bring the car in for an inspection. I went in for the inspection in December 2016 and they reported that there were no issues (despite video evidence). Today, December 2, 2022, the car (while gear shifted into park) again rolled down the driveway, across a street and hit my neighbor's house. This …

Owner report 11594280 · 2024-06-13 (June 13, 2024)
so after my initial report about my engine catching fire on the highway, I received an invoice for $5,000 for a used engine with 80k miles on it; plus another $2800 for the service fee. I already put down about $3900 for the engine repair. The mechanic sent me pictures of the engine with the holes on it that caused the damage (or the holes might have happened during the fire). I’m attaching photos sent to me, from my mechanic, showing the holes/damage on the engine, for your consideration and a photo of the initial repair bill (including receip…

Owner report 11648896 · 2025-03-18 (March 18, 2025)
My qx50 is currently back in the shop. So far I’ve spent about $12,000 on engine and transmission repairs and the NHTSA doesn’t seem to be doing anything about it. Now it needs a new “ignition coil” for another $1,000. I’m just at a loss for words!! I’m attaching the “Review of services” that was conducted earlier this month, when my Infiniti was in the shop and the diagnostic codes that came up when I had to have the vehicle towed there, less than a week later.
