2017 Infiniti QX70 problems

ELECTRICAL SYSTEM

The issue I have experienced involved my car stalling due to an inaccurate fuel gauge reading: basically, ran out of gas on a road while fuel gage was still showing half tank full. Luckily, was able to avoid any accident. The error code came up: P0462, which stands for “Fuel Level Sensor ‘A’ Circuit Low,” and indicates a problem with the fuel level sensor circuit. I was going to replace the fuel gauge/pump, but was told by a Nissan technical adviser at the dealership, the root cause is likely a faulty instrument cluster module, which is responsible for processing and displaying the fuel level information. This malfunction can lead to incorrect fuel readings, causing the car to stall unexpectedly.

VISIBILITY/WIPER

I was driving down the highway on [XXX] near Tucson, Arizona, when I heard a loud boom and my sunroof shattered. There were no cars in front of me, nor did I see anything in the road. It scared me but luckily I had my sunroof visor closed. I pulled off the freeway to check the damage, I had a shattered sunroof with scratches along the top of my vehicle from the flying glass. No call to police was made. I have not repaired sunroof and I am waiting back on insurance to get quote on replacement.

AIR BAGS

A sensor, or trio of sensors, in the passenger side airbag system failed. Nissan/Infiniti says they cant be sure which of the three sensors is causing the problem and needs to replace all three. One of the sensors is integrated into the passenger seat itself and therefore the entire seat must be replaced. This all adds up to a very expensive repair cost of over $10,000 for sensors that are not accessible by the user, and therefore failed because of a manufacturer's defect, and not because of wear and tear, or anything caused by the user. Infiniti is unable to tell me how the passenger side airbag will react in the event of an accident, so that leads me to beleive the vehible is possibly unsafe, and a risk to anyone riding in the front passenger's seat. The problem has been inspected and is documented with the Infiniti and the Sewell Dealership in Dallas, Texas. The vehicle has not been inspected by the police or insurance representatives, but rather the Sewell Infiniti Service Center. There is an airbag light flashing on the dashboard. That is what alerted me to the problem and prompted me to take it in for inspection of the issue.

STRUCTURE:BODY

While driving on the interstate, the sunroof exploded. There was no warning, no objects seen that could have hit it, good weather. The glass from the sunroof hit the car behind me and cracked their windshield. Thankfully our sun shade was closed so no shattered glass came into the car and no one was hurt.

UNKNOWN OR OTHER

Multiple incidents of car not starting or stalling in rain. 1. After a rainstorm while parked, noticed water on the driver side floor and dripping from the driver door side under dashboard, water coming from defective design of sunroof water drains/tubing which are clogged because the tube is too thin which traps common dirt and dust from rain and road water. A wider diameter tubing or requiring maintenance during oil change intervals (blowing air into the tubing to unblock the clog) would likely solve this defect and car owners money. Car would not start for 2 days afterwards until all the water was dried from interior cabin. This problem repeated itself every time it rained - I had to tape the sunroof closed to prevent water ingress as a temporary measure and ultimately had the tubing replaced by the dealership at a cost of $1326.97 which was not covered by warranty. A simple inexpensive fix of adding to the scheduled maintenance at oil change intervals, the blowing of air into the tube to clear blockage would solve this pervasive problem among Infiniti cars with sunroofs ( as suggested by Infiniti service rep). Even though Infiniti knows about this problem, they chose to not alert owners to clear the tubing now and then. Infiniti benefits from this defect with huge profits having to replace the entire sunroof drains at thousands of dollar expense for owners - Another incident 10/2023, 100 miles from home, while driving down [XXX] in a massive summer downpour led to water ingress into driver side cabin and stalling of the car on the highway and car refusing to go fast. After I turned the car off, the car would not immediately start again. After drying the driver side out with paper towels, the car eventually started. I turned on the car heater at full blast and temperature to dry the car floorboard. After it was full dry the car operated correctly but creates anxiety in no knowing if the car will stall out again.
