2011 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.
