2017 Infiniti Qx70 problems
The Infiniti QX70, formerly called the Infiniti FX until 2013, is a compact luxury crossover SUV produced by the Nissan-owned Infiniti luxury vehicle brand between 2002 and 2017. The FX replaced the QX4 as Infiniti's mid-size SUV. It shares the same FM platform as the rear-wheel drive Nissan 370Z, and it "made no claims of climbing mountains." Rather, its aggressive shape promised style and quick handling. The similarly sized Nissan Murano is based on the same D platform as the front-wheel drive Nissan Altima. The FX does not have a Nissan-branded equivalent and is not sold in Japan.
The FX introduced its second generation for the 2009 model year as the FX35 and FX50.
First generation (S50; 2003)
The nameplates FX35 and FX45 refer to the two available engines. The FX35 is available in two drivetrains, the RWD and the AWD, which are both fitted to a dual overhead cam 3.5-liter 24-valve V6 VQ35DE gasoline engine, with aluminum-alloy block and heads, electronically controlled throttle system, and low-friction molybdenum-coated pistons that makes use of the continuous variable valve timing which in part optimizes the opening of intake valves. This is also coupled with an electronically controlled super-wide ratio five-speed automatic with a manumatic shift mode that includes the option of sequentially selected manual gearshifts and downshift rev-matching.
The AWD FX45 incorporates a 4.5 L (4,494 cc) 32-valve V8 DOHC VK45DE gasoline engine with four valves per cylinder, microfinished camshafts with aluminum-alloy block and heads, low-friction molybdenum-coated pistons, titanium intake and exhaust valves, modular cylinder heads, microfinished crankshaft, lightweight pistons, super-silent single stage cam drive chain, and a Continuously Variable Valve Timing Control System that optimizes opening of intake valves. Development began in 1999 under newly appointed CEO Carlos Ghosn's NRP. Design work was completed in rapid succession in 2000, for late 2002 production. Designed prior to that, earlier on in 2000 under the "Bionic Cheetah" theme, the 2001 Infiniti FX45 Concept was introduced at the NAIAS in January 2001. From mid-2001, a new concept based on the production design was developed and completed in late 2001. Sketches were first released in late November 2001. The second-generation 2002 FX45 Concept was introduced in January 2002 at the NAIAS '02 as a thinly-veiled production FX (S50) and planned production was announced for early 2003. In January 2003, the 2003 FX45 made its debut at the 2003 NAIAS and went on sale January 24, 2003.
In 2003 for the 2004 model, changes were the addition of a standard eight-way power front passenger seat that replaced the previous four-way design, the availability of aluminum roof rails and chrome-plated 20-inch wheels. Also new were a dark silver metallic finish for the 20-inch wheels (non-chrome-plated), the addition of a standard HVAC filter for all models and the addition of a new Snow-Mode function.
In September 2004 for the 2005 model year, the FX range received enhancements such as a lane departure warning (LDW) system that helps alert drivers to an unintended movement of the vehicle out of a designated traffic lane. Infiniti's system monitored the lane markings to alert passengers via an audible buzzer that the driver is drifting unintentionally. The LDW system, which utilizes a small camera, speed sensor, an indicator, and an audible warning buzzer, was offered on models. The 2005 Infiniti FX was the first passenger vehicle to offer a lane departure warning system in the United States market. In addition to LDW, the 2005 Infiniti FX range was now equipped with standard roof-mounted curtain supplemental curtain airbags with rollover protection for front and rear outboard seat occupants.
Other changes included the addition of a dark chrome grille, headlight, and clear taillight accents to the FX45 (also available as part of the V6 Sport Package on FX35 models), a new key fob design for the Infiniti Intelligent Key system, and two new exterior colors, Sapphire and Sheer Platinum. Interior changes included a new standard etched aluminum trim.
Total 2007 sales of the FX45 were 1,598 units, about a tenth of the FX35s.

2017 Infiniti Qx70 complaints
The NHTSA has received 7 complaints about various vehicle components related to the 2017 Infiniti Qx70.
ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM PROBLEM
- Date Of Incident: 2024-06-01
- VIN: JN8CS1MWXHM
- Components: ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM
- Summary: 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 PROBLEM
- Date Of Incident: 2024-06-30
- VIN: JN8CS1MU6HM
- Components: VISIBILITY/WIPER
- Summary: 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 PROBLEM
- Date Of Incident: 2023-11-01
- VIN: JN8CS1MU2HM
- Components: AIR BAGS
- Summary: 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 PROBLEM
- Date Of Incident: 2024-05-29
- VIN: JN8CS1MU0HM
- Components: STRUCTURE
- Summary: 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,UNKNOWN OR OTHER,ENGINE PROBLEM
- Date Of Incident: 2023-08-05
- VIN: JN8CS1MU0HM
- Components: ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE
- Summary: 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.

I love my car! Although, there were a few days after I got it where the camera wasn't working. Other than that, it's a 5-star car!

I've owned/leased 3 FX35s and now a QX70. I absolutely love my car! It's powerful, fast, comfortable, spacious, and handles well in all weather, especially snow. Plus, it's a great looking car! I've made a few upgrades, like adding K&N air filters and running only synthetic oil, and I maintain my car like a racing team. Even at 50K miles, I still have the original tires and brakes, which is a testament to how well this car is built. It's a low-maintenance dream and I rarely need to visit the dealership. The only minor issue I've had with Infiniti cars is the paint job. At $55,000, I would expect a better paint job to be offered. However, when compared to other cars in the same price range, German cars do have significantly better paint jobs than Infiniti.

I’m a car enthusiast with 2 small kids and this car fits the bill for fun to drive, room for the kids and all their stuff, sounds amazing, drives great and is perfect for all weather. I love the cost of ownership, reliability and luxurious limited interior. The only downside is the dated infotainment and instrument cluster, but overall I really enjoy it!
-
This is my third Infinity. Two x35's and now the X70. Obviously, you can tell that I love this car. Its distinctive styling and performance make it my all-time favorite.
-
So glad to hear that you've owned this car for almost 4 years now and have only needed to replace the rear brake pad! It's always great to hear about a car that's reliable and low maintenance. I understand that you may be missing some of the latest technology that other cars have, such as the early departure warning, but overall it sounds like you've had a positive experience with this car.

My wife and I drove from Gainesville, Florida to purchase this vehicle. However, we were disappointed to find that the brakes and rotors were worn, and the aftermarket rims and tires were scratched on the driver's side and worn to the point of needing replacement. Although the sports package was described online, the tires and rims did not meet our expectations. We asked for a vehicle inspection report, but were told that it was not available as the service department was closed on Saturday. We were hoping for a price drop of $1500 to buy a set of used exact factory 21” from EBAY, but the sales manager only agreed to reduce the price by $500. Despite these issues, we appreciate the sales manager's efforts to work with us. It's unfortunate that the dealership was not more flexible in resolving these issues, especially since the vehicle has been for sale since November 2020. Thank you for your time.

Hello! I recently had the pleasure of comparing a used QX70 to a QX50. While I was originally looking at 2015 models or earlier, I found that the QX70 was just too big for me. As someone who is 5'-4

The car unfortunately has a dangerous blind spot at the driver's rear right side. Additionally, I had to replace the transmission at 74K miles, only 4K miles past the bumper-to-bumper warranty. I contacted Infiniti Consumer Affairs to see if they could offer any assistance, but unfortunately they declined. The transmission ended up costing me $2,500. To make matters worse, at 85K miles, the clear coat finish is wearing off in multiple areas and looks terrible. While I could bring it to a body shop and have the clear coat and all the paint sanded off and have the entire car repainted, that would cost me thousands of dollars. This was my first

I rented this car and drove 900 miles in it (I got in with 8 miles, returned with 908). Overall, my experience could have been better. The cabin was nice and well-appointed, with easily placed buttons and intuitive controls. I was impressed by the stability control intervention, which was quick and predictable when cornering and the rear started to break away, especially given that it was January and I was in northern Minnesota. However, the cabin felt a bit claustrophobic and outward visibility was below average, which made it difficult to look over my shoulder and around blind spots. The ride was also very jumpy and uncomfortable on undulating roads, which was noticeable when the headlights were on. The USB integration was sporadic, sometimes requiring more effort to get it to work. But what was most noteworthy, in a negative sense, was the gas mileage. Despite mostly highway driving, the car returned below 20 mpg on average, which is poor for a smaller SUV. Additionally, the engine requires premium gasoline, which adds to the cost. While there are some things to like about the QX70, there are much better options out there.

Hey there! I noticed that you mentioned the car looks pretty on the outside and should be comfy inside, but unfortunately, it didn't meet your expectations. You also mentioned that the V6 was loud and the pickup was slow and rumbly. It seems like the car has been driven quite a bit, so maybe the previous owner didn't take the best care of it. Thanks for sharing your thoughts!
