2011 Infiniti Fx 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.

Congratulations on your purchase of the 2011 FX35 for 50 grand! The color and interior are both lovely, although it would have been nice if they included wood trim. The wheels are a bit small at 18 inches, but the car still has amazing performance and is very fun to drive. The 11 speaker Bose system works great in the front, although I wonder if the rear back speakers are supposed to work loud. The seats are very comfortable, although the passenger seat only has 8-way adjustment and no lumbar support. Unfortunately, there is no 6 CD changer or rain sensing wipers. However, the ride is smooth and the exhaust noise from the back is a nice touch. I'm not sure if the car has active head restraints with adaptive front headlights, but overall it sounds like a great car!

Your 2011 fx has 47k miles! That's great to hear. It's wonderful to have a dependable SUV like the fx35. I completely agree that vehicles made in Japan are the best overall. The craftsmanship is excellent, and the doors are well aligned. The paint looks great, and there are no oil leaks. It's clear that it's a very well-built vehicle. I'm glad to hear that you plan to drive your fx35 for a very long time!

I hope you're doing well! I wanted to share my experience with my FX so far. I picked it up the Wednesday before Thanksgiving and have just over 1000 miles on it. I have to say, the seats are extremely comfortable and the ride is great. It's also very quiet, which is a huge plus. However, there are a couple of things that bother me. Compared to my 2007 Acura MDX (my other vehicle), the voice recognition system is a bit clumsy, especially when it comes to making phone calls. The other thing that bothers me, and this may be petty, is that the center armrest is a bit short. I always drive with my left arm on the armrest, but with it being a bit short or too far back, my elbow rests wrong and it's a bit uncomfortable. Other than that, I really like the truck. Thanks for listening!

I recently test drove a few different models of the FX35, including the 2003-2006 versions. While those felt quite large, I was pleasantly surprised by how the 2011 model felt much smaller and more like a sedan. The interior is luxurious without feeling too delicate or high-maintenance. Despite being larger and heavier than my previous car, a 03 350z, the 2011 FX35 handles just as well and is a joy to drive. The V6 engine is plenty powerful and always puts a smile on my face, even after 3 months of driving. The sound system is also fantastic. I love this car so much that I find myself making excuses to go for a test drive or just sit in it. I plan to keep it for a very long time, even passing it down to my kids when the time comes. I'm confident that it will last for many years to come.

Great SUV! I'm so glad to hear that you're enjoying the ride comfort and the impressive 390 hp/369 ft lbs of torque. While it may not have a lot of room for storage or rear passengers, the 50xS is definitely a car that's all about the power. It's also great to hear that it's moddable! Thank you for sharing your thoughts on this awesome car.
