2024 Infiniti QX60 Electrical System Problems

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.

Most issues began around the 6th month of the first year of ownership and have persisted. Current mileage is ~31,500. Safety-related defects: 1.Washer system leak/empty reservoir: washer fluid repeatedly drains/ends up empty, preventing windshield cleaning while driving and reducing visibility. Began after a dealer visit on 06/03–06/04/2025 for panoramic sunroof noise (“concern began after prior dealer visit on 06/03–06/04/2025”). 2.Rear driver-side window intermittently lowers by itself (electrical), creating distraction and a safety/security risk. 3.Side mirror intermittently fails to unfold/open, reducing rear/side visibility. 4.Water intrusion into cabin from top of front passenger door area during rain/car washes, causing staining/odor and raising concern for electrical components/safe operation. 5.Panoramic sunroof creaking noise when closed (driver distraction); prior service attempt (~2 days) did not resolve. 6.ADAS concerns: Automatic Emergency Braking and Parking Collision Warning intermittently fail to activate / provide alerts when expected, creating driver distraction and uncertainty about proper system operation. No crash or injury has occurred. Please document these issues and evaluate for a potential defect trend/recall if similar complaints exist.

I am submitting this to supplement NHTSA Complaint No. 11704996 regarding a 2024 INFINITI QX60. Current mileage approx. 31,500. No injuries. Crash/Incident (property damage only): Within the first 2 months of ownership, while backing into a parking space at a grocery store parking lot, the Parking Collision Warning did not alert and Automatic Emergency Braking did not activate. I struck a shopping cart I did not see, causing minor damage/dent to the liftgate (no injuries). Additional ADAS safety concern (near-miss / repeated events): During the first year of ownership, on at least two occasions while using Intelligent Cruise Control / driver assist (steering assist) on a highway, when the vehicle ahead braked, my vehicle did not slow down or brake as expected and continued approaching at the prior speed. I had to brake immediately and steer to avoid a collision. No crash or injuries occurred. Similar instances have occurred additional times; however, I was monitoring the system and manually braked in time when it did not slow/stop from a safe following distance. I am concerned about intermittent non-response of these driver-assist braking functions. Ongoing safety-related issues since about the 6th month of the first year: 1) Windshield washer system leak/empty reservoir (reduced visibility). Concern began after prior dealer visit on 06/03–06/04/2025 for panoramic sunroof noise. 2) Rear driver-side window intermittently lowers by itself (electrical). 3) Side mirror intermittently fails to unfold/open (visibility). 4) Water intrusion into cabin from top of front passenger door area during rain/car washes (photos available), raising concern for electrical/safe operation. 5) Panoramic sunroof creaking noise (distraction). Request NHTSA document and evaluate for potential defect trend.
