POWER TRAIN
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.

POWER TRAIN
I was driving down the highway and the revs went up really high with some banging and clanging, the check engine light came on and the gears stopped shifting. The dealer told me the transmission valve body failed and it seems to be a common issue in these cars. Not safe to drive as the gears wont shift and this seems to be a sensor in the transmission that is doomed to fail after a matter of time. Infiniti reengineered this part because they know it is going to fail but have not issued a recall.

ELECTRICAL SYSTEM, SERVICE BRAKES
Brake fluid began leaking onto the ABS actuator circuit board and created an electrical fire. This melted the engine harness and the connector to the abs module. This was confirmed by dealership technicians at Sewell Infiniti - Dallas. Dealership informed me they could not fix the vehicle because the part needed to replace (affected by a different recall), was discontinued and made me tow the vehicle to my house. The issue was confirmed by mechanics at Parkwood collision - Frisco. InfinitiUSA customer service acknowledged the issue and that they would have the original supplier of the engine harness (discontinued) make me one if I purchased at the dealership (which to my understanding would not solve the original issue at hand). It is available to inspect upon request. I have pictures and videos. The fire did put myself and others at risk as the engine harness was melting and shorting out while pulling my vehicle to the side of the road. It has not been inspected by insurance rep; at this time. There were zero issues with the vehicle or modifications to vehicle at the time of the incident. There were no warning lamps or symptoms until it was too late.

ELECTRICAL SYSTEM, FUEL/PROPULSION 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.

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.

ELECTRICAL SYSTEM, ENGINE, 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.

POWER TRAIN, ENGINE
The contact owns a 2017 Infiniti QX70. The contact stated that while driving approximately 55 MPH, the transmission was hard shifting into gear. The contact stated that the transmission failed to shift into the proper gear. Additionally, while driving in the rain, the vehicle hydroplaned on three occasions. The check engine warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed that the valve body needed to be replaced. The battery was replaced. The vehicle was repaired but the failure recurred. The manufacturer was not contacted. The failure mileage was approximately 85,000.

The car seats show that they have the anchors in the back seat for a child’s car seat. We do not have any anchors for our back seat. At all. But do have the indicators that we do have them on the seats.

SERVICE BRAKES
I was backing out of the garage intending to stop on the driveway and inspect tires in the sunlight. The brakes had no effect and the car proceeded across the street and up the neighbor's driveway and finally stopped just short of their garage door. All this time I was applying the brake repeatedly with no result. Why it stopped just in time to save neighbor's door I don't know. I was too panicked to think of using the parking brake until later. A similar incident had occurred about a year ago in a restaurant drive-through. At that time I rear-ended the car in front about instantly, the cars were so close together. It happened so fast I thought maybe I had pushed both accelerator and brake with one foot, so I called it driver error and thought no more about it. This time there was plenty of time and no doubt about it, I applied the brakes many times and nothing worked until right at the top of their driveway. The current incident happened on May 16, 2021. I had taken the car (Infiniti QX70) to Nissan Reno on May 14 for oil change, filter, and brake fluid exchange, since Infiniti Reno was closed until further notice. The timing makes me wonder whether something happened during the fluid exchange. I haven't been back to Nissan Reno, not sure whether to trust them. This was reported to Ask Infiniti web site, and their suggestion was to take the car to nearest open Infiniti dealer in Roseville CA about 120 miles away. With questionable brakes? I don't think so.

STRUCTURE:BODY
THE SUNROOF EXPLODED AT APPROX 8AM 5/30/2017. THE EXPLOSION WAS PRECEDED BY A RATTLING NOISE, THEN A VERY LOUD AND SCARY BANG. I WAS TRAVELING APPROX 65 MPH ON I80 W (BETWEEN VACAVILLE AND FAIRFIELD CALIFORNIA). MORNING TEMPERATURE MILD--PROBABLY IN THE UPPER 60'S. I PULLED OFF THE HIGHWAY AND FOUND THE SUNROOF GLASS HAD FIRST EXPANDED THEN SHATTERED. BECAUSE THE INSIDE ROOF DOOR WAS CLOSED, SHARDS OF GLASS DID NOT FALL INTO THE CAR, BUT THEY DID DO SOME DAMAGE TO THE PAINT JOB. CALLED THE DEALERSHIP WHO HAD ME BRING IT IN THE NEXT DAY--I WAS TOLD THE REPAIR WOULD NOT BE COVERED BY MY WARRANTY NOR MY EXTENDED WARRANTY BECAUSE THEY BELIEVED SOMETHING HIT THE GLASS. WHEN I TOLD THEM NOTHING HIT THE GLASS AND POINTED TO THE EXPANSION OF THE GLASS THEY STILL REFUSED TO COVER THE REPAIR. I REPORTED THE INCIDENT TO START FARM INSURANCE AND THEY COVERED THE $1850 REPAIR BILL. MY CAR WAS IN THE SHOP FOR OVER 2 WEEKS BECAUSE THE REPLACEMENT GLASS ORDERED BY THE DEALERSHIP ARRIVED SHATTERED TOO. THEY MUST BE USING INFERIOR THIN GLASS TO HAVE HAD THIS HAPPEN!

EXTERIOR LIGHTING
THE INTERIOR COURTESY LIGHTS UNDER THE DASH REMAIN ON WHEN CAR IS RUNNING. DURING NIGHT TIME DRIVING THIS IS VERY DISTRACTING TO ATTENTIVE SAFE DRIVING. ACCORDING TO INFINITI, THIS WAS ENGINEERIED TO REMAIN ON AND THERE IS NO WAY TO TURN THE LIGHT OFF. THE CHANGE TO THE LIGHTING WAS DONE ON MODELS BEGINING WITH 2014. IN EARLIER MODELS ALL THE AMBIENT LIGHTS GO OUT WHEN THE CAR IS STARTED.
