While driving i heard a roaring noise from my engine and my car’s a/c stopped cooling. I have no warning messages from car regarding the engine. The noise only stops once the car is fully powered off. I recorded a video of the noise and alert panel that shows no warnings/issues. Will be contacting my local service department.
About five months ago, while driving on the highway, the care would say it's in drive, but sounded like it couldn't get out of 1st gear and i'd get high rpms. Thankfully there was stop-and-go traffic and i didn't have to exit pull off the highway or hit high speeds. I exited at the next exit and, as soon as the car stopped, it wasn't possible to get it into gear. Eventually the car started and i was able to get into gear and drive it using manual drive mode. Once at the dealership we were told it was a bad vcr and they needed to replace that to get it going. That was around 38,000 miles. This most recent incident, i had just gotten onto the highway when i started to hear a low whiney noise when pressing the accelerator. I only had a few miles till my exit and decided to continue, thinking it might just be debris or something. After exiting, i literally rolled into the gas station because the car, despite being in drive, was not in gear. The car stalled and i couldn't get it started, or i could get it started, but it refused to go to neutral to allow me to push it out of the way. Eventually, the car started and i was able to put it into drive. Thinking it was the same issue, i planned to drive it the 2 miles home. I made it to the first traffic light and the car turned off, leaving the me stranded in the middle lane of the road. I called the police and tow trucks to come help me get the car moved (no one knows how to put the car into an emergency neutral position including the 2 officers, 4 tow truck drivers and an infiniti mechanic that was driving by). Eventually the tow truck came and i was able to drop it off at the dealership, who have told me there is "a chunk of bearing material in pan with copper particulates. " i'm currently around 40,000 miles.
Engine acceleartion issue. Rpm goes high but car struggle to speed up.. At first it happened when car was at stop light, struggle to move forward.. Took to grubbs infiniti.. At first,dealer could not replicate the issue, but luckily i had taken the video of the issue i had. Than the dealer was finally able to experience the issue themselves and replaced the transmission thinking that was the issue. I took the car after repair and within 3-4 days i had the same issue. This time i was driving in a freeway at 60 mph. When i hit the gas pedal to accelerate faster,the engine rpm went high but instead of speeding up, car felt like slowing down. So i exited the freeway to service road. Once the speed went down to 20mph, it didn't go any higher than that. This time there was a check engine light on i took it back to the dealership. They again could not replicate the issue and just did the ecm software update. I took the car home but after driving less than 20 miles,the car had the same issue. I again took it back to delearship. This time they are replacing something called vcr.. Still waiting now
I purchased this 2021 qx50 infiniti on [xxx] and have experienced consistent engine knocking. In checking out this problem, i have found that it is apparently a widespread problem with the engine in 2021 qx50 vehicles and can possibly lead to engine lock up and engine failure. The engine thus far has not locked up or failed. I have reported the issue to the dealership, infiniti of gwinnett located at 3090 satellite blvd, duluth, ga 30096 and am scheduling to have the dealership investigate the problem. Needless to say this is a major concern and if there are ongoing nhtsa investigations and findings i definitely want to be made aware of same.

I was driving my vehicle and i stopped at a stop sign. When it was clear i proceeded onto the highway. I took a left at the first exit and could hear a weird knocking noise. I could also feel the car was not accelerating properly. The vehicle was not driving right. I called a tow and took it to a repair shop. The owner of the car shop said that a rod had been blown and i need a new engine. I am 7000 out of my drive train warranty.
The car completely stalled while going uphill. It restarted a few minutes after. I received 3 email notifications from infiniti stating that my engine may have an emission control system malfunction. I took the car into the infiniti dealership. They stated that the vehicle test was driven for 24 miles. Could not duplicate customers concern and is not stalling when going up hills. Scanned for codes and found multiple past codes. Drove until moniters were set. Rechecked for codes and no codes were found. No further action required, working as factory intent and design. Called infiniti consumer affairs who stated that they could do nothing else too detect what is wrong with the car.
The contact owns a 2022 infiniti qx50. The contact stated while driving from a complete stop, the engine made an abnormal knocking sound. There was no warning light illuminated. The contact stated that the failure had been recurring intermittently while driving from a complete stop. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 3,000.
