“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). …”

“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.”

NHTSA complaint #11648896, filed 2025-03

“The contact owns a 2016 Infiniti QX50. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The contact stated that following the warning light illumination the vehicle hesitated to accelerate. The vehicle was taken to the mechanic and diagnosed as a speed sensor module located inside the transmission. The contact was advised the module being in the transmission caused the transmission to overheat requiring valve body replacement. The manufacturer was not made aware of the failure. The vehicle was not repaired. …”
