What owners report

Owners of this model year most often describe engine trouble: knocking, rattling or grinding sounds, loss of power and, in some cases, engines that seized and were diagnosed with metal debris in the oil pan. Owners also frequently report the automatic emergency braking engaging when nothing is in front of the car, and a cooling-fan roar accompanied by weak A/C. Several engine complaints reference recall 25V437000 and note that parts for the recall repair were not yet available.

  1. Engine

    Engine knocking, stalling and bearing failure

    • 79 complaints (54%)
    • median 92,000 mi at 6.8 yrs old (27 state mileage)
    • 4 mention a crash, fire or injury
    • owner-quoted repair $4,630 (median of 6 quotes)
    • filed 2018–2026

    Complaints describe rattling, knocking or grinding noises from the engine, sometimes at startup or idle, followed by shuddering, loss of power or a stall while driving. Several owners say a shop found metal shavings or glitter in the oil pan and diagnosed bearing failure or a seized engine requiring replacement; some report smoke or a burning oil smell. Many of these complaints reference recall 25V437000, with owners stating the dealer had no recall parts available yet or that coverage of the repair was disputed. Reported across a wide mileage range, from under 20,000 miles to well over 100,000 miles, often at highway speed.

    Recall 25V437000

    What to check: Ask whether the 25V437000 recall inspection was completed and what it found, and whether the oil pan was checked for metal debris. Have a pre-purchase inspection look for unusual engine noise and request the oil service history.

    2 excerpts from owner complaints in NHTSA records

    “A few months ago, I received an email from CarFax letting me know that my vehicle, a 2019 Infiniti QX50 with 2.0L Turbo Engine had a major recall (NHTSA Recall Campaign No. 25V-437). The letter indicated the recall was due to issues with the engine bearings which could lead to a catastrophic failure. I wasn't sure what this meant, so I took the car to Austin INFINITI. The technicians checked the oil pan to see if there were issues. …”

    NHTSA complaint #11708940, filed 2026-01

    “Engine made a pop sound while getting onto the freeway. It started to slow down and then I had to pull over and stop. Took to the mechanic and he explained there was metal shavings in engine. I needed to replace the whole engine.”

    NHTSA complaint #11664372, filed 2025-06
  2. Forward collision avoidance

    Automatic emergency braking activates with no obstacle

    Mentioned in 12 of 60 sampled complaints

    Owners describe the car braking hard on its own at city and highway speeds when no vehicle or object is ahead, sometimes with warning beeps and sometimes without. Dealers reportedly reset the system, told owners they could not reproduce it, or said nothing could be done without a stored code. Some complaints mention related false proximity warnings or the screen going blank around the same time. Reported from very low mileage, often under 25,000 miles, at speeds between roughly 30 and 70 mph.

    3 related service bulletins

    What to check: During a test drive, note whether forward-collision or AEB warning lights stay on, and ask whether any related service bulletin software updates were applied. Check for stored diagnostic codes for the laser/radar unit.

    2 excerpts from owner complaints in NHTSA records

    “Dear NHTSA, my automatic emergency braking system warned and autobraked my vehicle during my normal driving without any signs of emergency - no cars are in front of me along the whole street. Luckily, no one was hurt. My webcam caught it. If possible, please put attention to this case as all the owners are in danger. It seems that I cannot upload videos but I will be very happy to provide it as an evidence.”

    NHTSA complaint #11328824, filed 2020-06, 10,000 miles

    “Dating back to november 2019, my vehicle's automatic emergency braking have engaged 3 times without reasonable cause at speeds that vary from 40-70 MPH. The first two incidents were on normal city roads going approximately 40-45 MPH. The last incident (june 2020) happened while driving on a highway, with no traffic around, going ~70 MPH and my vehicle almost came to a complete stop. The first time I took the vehicle into the dealership, they reset the system. …”

    NHTSA complaint #11337619, filed 2020-07, 24,000 miles
  3. Transmission and drivetrain

    Hesitation, shudder and transmission engagement problems

    • 27 complaints (19%)
    • median 54,010 mi at 6.3 yrs old (14 state mileage)
    • 1 mention a crash, fire or injury
    • filed 2019–2026

    Owners describe the car failing to accelerate when the pedal is pressed, high RPMs without power, shuddering or hesitation, and difficulty selecting or staying in gear, including dropping into neutral. Some complaints say the dealer replaced the variable compression actuator or related components; others describe repeated visits without a lasting repair. Reported from a few thousand miles up to around 50,000 miles, most often in city or stop-and-go driving.

    Recall 25V437000

    What to check: Test drive at low speed and from a stop, watching for hesitation, shudder or delayed engagement, and confirm the transmission and variable compression actuator service history.

    2 excerpts from owner complaints in NHTSA records

    “When driving the car or when the car is not moving ex: waiting at an intersection the car has gone from the drive mode to neutral for no apparent reason..this has happened on 3 different occasions most recently on 3/2/19..I want to check to see if others with same vehicle are having the same problem. Went to pull out in oncoming traffic and was unable to do so because the car went into neutral without my knowledge..”

    NHTSA complaint #11184158, filed 2019-03, 1,178 miles

    “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. …”

    NHTSA complaint #11579772, filed 2024-03

Buying note. Have any 2019 QX50 you are considering inspected for engine noise and oil-pan debris, and confirm the status of recall 25V437000 before purchase; also test the automatic emergency braking behavior and the A/C fan on a warm day.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
