2017 Infiniti QX70Recalls, problems, MPG & safety

“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.”

“When driving on the highway the car stopped changing gears and then flashed a check engine light, this has already happened to me on another QX70 infiniti that I had previously owned so it seems to be a common problem especially since Infiniti has now updated the part stamping to a G2A model from an MB3 since they know these parts fail. The car becomes undriveable on the road as gears stop shifting. This isn't something that is determined on how you drive but merely a sensor in the transmission that is prone to failing and creating an unsafe situation. I searched it online and it appears many people have problems with the transmission valve body failing on these poorly designed parts.”

“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,…”
