2010 Infiniti Fx35 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.

To all those who have concerns about transmission issues, I want to assure you that it's not a serious problem. Although it may shift a little oddly, it's hardly noticeable. I understand that everyone has their preferences, but I believe this car is fantastic. It's fast, comfortable, and reliable. I researched many SUVs, and this one is by far the best. The interior of the FX alone is better than those of the X5, M-B, and Porsche. I've had this car for a few months, and it's been very enjoyable to drive. It's like buying a 350Z but in an SUV body. If you're not into sporty cars and prefer something more traditional, I suggest you look into a different car. However, if you're looking for a car that's both sporty and practical, the FX is an excellent choice. Thank you for considering my opinion.

I hope you're doing well! I wanted to share some information about my FX35 FWD with Premium, Deluxe Touring, Navigation, Technology, and Rear Entertainment Packages. I've been the original owner since 3/2009 and have driven it for 130,000 miles. There's still a lot to love about this car, including its reliability (no problems to date except a cracked hose and routine maintenance), great handling (it feels amazing on the road and handles the twisties like a sports car), luxurious interior, excellent side bolsters and heated/cooled seats, and super looking 20

Our FX35 was purchased last February and has been a great investment. Although my partner had some reservations, I have been thoroughly satisfied with our purchase. The car is an absolute joy to drive and the interior is top-notch. While the exterior may take some getting used to, the car's performance more than makes up for it. Although there were a couple of issues, such as the poor rear visibility and the transmission's tendency to shift roughly, these have been resolved with the available transmission re-flash (ITB09-032). I highly recommend asking about it. Thank you, Infiniti!

This is the perfect sports car with a backpack! Our second FX (Prem/Tech/Nav/RearEnt.) is just as enjoyable as our first '06 model. Although the new 7-speed had some quirks, they were resolved with software updates. With features like XM/cooling seats/dvd/nav/mp3/rain sensing wipers, the FX is an excellent cruiser for long road trips. Adaptive Cruise and Lane Departure Prevention are game-changers for long-distance driving. We recently drove 900 miles on the highway with cruise control set at 75mph and averaged 24 mpg. The technology, maintenance, and reliability are simply amazing and offer great value compared to European counterparts. You'll have a blast driving it, so go ahead and buy one!

I'm so glad to hear that you love the Infiniti brand! It's great to hear that you've had such a positive experience with your previous Infiniti and that you ultimately decided to purchase the 2010 FX35. The quality of the interior components and the engine sound are definitely impressive features that I'm sure you'll continue to enjoy. And I completely agree with you - the exterior looks are fantastic! Thank you for sharing your thoughts with us.

The transmission not only fails to upshift smoothly, but it also causes the engine to rev up to 5k as I am pulling in to a stop, which is a dangerous situation. This issue is similar to the one experienced by others and reminds me of the mid-80's Audi. In addition, the Nav screen functions intermittently, the iPod does not charge, and the brakes pull to the left and right. Overall, this machine is not satisfactory. However, it is on a 4-year corporate lease.

This is my third Infiniti after driving an '04 FX and an '05 G35, which I enjoyed tremendously. Although I was excited about the new and improved FX for '09, I have been disappointed with its performance. I have experienced some issues with the shifting, especially in slow and go traffic, where it seems to struggle to find the right gear. However, I have found that it performs great from a stop. I have also noticed that it can be a bit jarring when coming to a stop. Overall, I still appreciate the incredible new styling, but I hope that Infiniti can address these performance issues in future models. :)

This is my second Infiniti after the '04 FX, which I really enjoyed. However, I am disappointed with the performance and fuel economy of my new 2009 FX35. Despite driving mostly in the city, my old car was showing about 13-14 mpg, and unfortunately, the new one is showing the same. The driving experience has been less than ideal, with shifting issues in slow traffic and a feeling of choking on fuel when starting to drive. I have taken the car to the dealer a few times, but despite their re-programming efforts, I have not seen any improvements. I hope to find a solution soon, as I have always been a fan of Infiniti cars.

Hello! I wanted to share my experience with the Infinity FX35. I have noticed that the transmission can sometimes get stuck between 3rd and 4th gear, causing a lag in speed. This can make passing or merging into traffic a bit nerve-wracking. Additionally, I have experienced some lurching forward when coming to a stop. I understand that these issues may be related to the change from a 5 speed to a 7 speed transmission. I have done some research and found that other drivers have experienced similar problems. The dealer has offered to take the car back for a fee, but I am still considering my options. Thank you for listening to my concerns.

Before you decide to spend 45K (+) on this vehicle, I would like to bring to your attention a major design flaw in its transmission. I recommend that you take the time to read all of the consumer reviews at Edmunds and various Infiniti web forums. The transmission upshifts too quickly, which means that you are in 7th gear by 38 MPH. This makes getting up to speed (downshifting) in a passing situation difficult and, in my humble opinion, a safety issue. Although I am not pleased with this vehicle and will be scrapping it soon, I encourage you to make your own decision. It is worth noting that there are numerous customer complaints about this issue when this model was introduced. I hope this information helps you make an informed decision. Thank you for considering my opinion.
