2024 Infiniti QX60

After going through a touchless car wash with undercarriage spray and clean, the vehicle stalled 5-10 minutes later. This occurred after the wash was completed and driving away. Suddenly the engine began to lose power, stumbled, and then died while driving. If I had to guess this was a sensor or some electrical component that may have been affected by the water spray from underneath. There were no check engine or other warning lights when this occurred. Attempted to restart the engine. After a few seconds longer than normal it started and appeared to run fine. Drove it home afterward. If the water caused the issue there are serious implications for driving in rain, through puddles, or snow as that water can migrate up into the engine compartment during driving (would be especially dangerous at highway speeds). If it makes any difference, the vehicle did idle fine for a few minutes after leaving and stopping outside the touchless car wash. Only after a walkaround, removing trash from the vehicle, and then driving away did the stall occur.

On February 27th, 2026, around 2:00 PM, while driving my 2024 Infinity QX60 on Hwy. 459 in Birmingham, AL, at approximately 70 mph in heavy traffic, the engine suddenly shut down completely and shifted into neutral without any prior warning lights, noises, or symptoms. I had great difficulty figuring out what had happened, and struggled to avoid being hit while crossing over three lanes to coast to the shoulder. I attempted to put the car back into drive without success and was absolutely terrified as I barely missed being hit by an 18-wheeler traveling behind me at a high rate of speed. The car was shuddering, but I managed to drive a short distance to the Birmingham Nissan dealer. After an inspection, they stated it was due to an improperly installed air filter that interfered with the MAF, and I was told I had to pay $1,000 for repairs. The Forward Collision warning sensor went out after the MAF was repaired, but the car was released to us. We had to take it right back to the dealer and leave it again.

While at a stop in DRIVE, the car would automatically shift itself into Neutral without warning. When I contacted the dealer, they were aware of this issue in other vehicles. I brough the car in for service and in the description of the work, the mention that they knew where to address the problem, as it is a known issue. The dealership stated, "PREFORMED BATTERY PERFORMANCE TEST PER PREVIOUS TECH LINE CASES WITH SIMILAR ISSUES. BATTERY PASSED TEST WITH CPX900 AND DCA8000. CONTACTED TECHLINE AND WAS INFORMED TO CHECK FUEL PRESSURE AND FUEL PRESSURE BLEED OFF DUE TO SIMILAR CASES EXHIBITING SAME CONDITIONS. FOUND LPFP TO BE ONLY PRODUCING 45PSI AT IDLE AND IMMEDIATE BLEED OFF WHEN VEHICLE SHUT OFF. CAUSING CAR TO SHIFT INTO NEUTRAL AS FAIL SAFE * REPLACE LOW PRESSURE FUEL PUMP PER TECHLINE RECOMMENDATION"
