general problems of the 2013 Infiniti JX35

While driving on the freeway, the vehicle's driver assistance system suddenly became unavailable. Although the car was still able to move, the transmission would not shift gears. The engine rpms rose unusually high — when applying pressure to the gas pedal, the rpms could reach 4,000 to 5,000, but the vehicle accelerated very slowly. I could only maintain a speed of around 50–60 mph. It felt like the transmission was stuck in one gear and the power was not being properly delivered to the wheels. This limited acceleration and loss of responsiveness created a significant safety concern on the freeway. The following day, the check engine light turned on. I took the vehicle to autozone for a diagnostic scan, which returned multiple fault codes: p0840 (transmission fluid pressure sensor/switch a circuit), p0715 (input/turbine speed sensor a), and p0746 (pressure control solenoid a performance or stuck off). After researching the issue, I found that many other Infiniti Jx35 owners have reported similar failures involving the cvt transmission. This appears to be a recurring defect that significantly affects drivability and safety. The repair estimate I received is over $4,000, and the vehicle remains in a compromised condition. I am reporting this as a safety concern involving powertrain failure, elevated engine stress, and loss of acceleration control.

The contact owns a 2013 Infiniti Jx35. The contact stated while driving 20 mph, the vehicle failed to accelerate as needed. The abs system was activated. The contact stated while driving 20 mph the vehicle independently accelerated to 60 mph. The vehicle was jerking while the accelerator pedal was depressed to the floorboard. The contact was able to pull over. The contact called the local dealer but was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA hotline. The contact stated that the failure was related to NHTSA campaign number: 13v445000 (service brakes, hydraulic, electrical system). The failure mileage was approximately 161,000.

While driving the vehicle randomly looses power to the engine and all electrical power goes off. The dash is completely without power. Engine will not accelerate and looses power steering like the engine is off. After a few moments all power is returned and engine comes back on to normal operation.

I have replaced the battery in my 2013 Infiniti Jx35 3-4 times. Dealership continues to say this is normal. Recently, multiple exterior light bulbs have gone out and the �instrument cluster� suddenly went dark while I was driving. I cannot see meters like gas, speed, etc. I cannot hear or see my blinker or headlight indicators. Additionally, all the power controls including speed control no longer work. I am concerned there is a significant electrical safety hazard. I no longer feel safe driving this car with my children. There are many reports of similar claims for the 2013 Infiniti Jx35 electrical system online. I would like Infiniti to take responsibility for knowingly putting people in danger by refusing to acknowledge and fix a known problem with this car.

Car starts to shudder and shake, while trying to accelerate. This is a transmission issue.

Car shudders and stalls when is coming to a stop or slowing down and trying to accelerate will stall and skip rpms I've seen many complaints about the same thing.

While car was in motion, full dashboard instrument panel stopped working. No turn signal indicators, no speedometer, no fuel gauge.

The problem: affected vehicles may exhibit a shudder or vibration while in gear. This may be due to a faulty continously variable automatic transmission, drivechain or valve body inside the transmission. Vehicles affected by this service campaign: 2013 Infiniti Jx35 2014 Infiniti qx60 2015 Infiniti qx60 I’ve dealt with infinity hundreds of times. They even had a mechanic take the car home and he experienced the same thing. Still nothing been done. You can google the problem and no one has got it fixed. As soon as your warranty ends then they say you need a new transmission. I’m still under warranty I’m at 90,000 miles , as it gets closer to hundred thousand miles. I’m sure then there going to say I’m going to need a new transmission. The problem if I need to cross the street and a car if coming at a distance my car flutters to cross the street almost wrecking several times.

Car wouldn't move from p (parking) gear at first. When it eventually started moving, it wouldn't accelerate to more than 20 mile per hour even though it's at 5-6000 rpm and eventually the car stop moving completely even though the engine was on. Was told by the dealer that it was due to a defective transmission so brand new transmission was installed. 1500 miles(3 months) later the car stopped moving while driving on 2/11/14. Car started slipping backward in the hilly road. Leaky transmission fluid was at the site. Dealer is installing another "new" transmission while there are less 6500 miles in the car. The car has been with the dealer for more than a week now.

Car strongly vibrates/shudders at approx 20 mph and thereafter, and I had to take foot off pedal to get it to shift gears. Engine light comes on. At first visit to dealer, on 9/7/2013, (I'm currently on 4th visit since getting car), they claimed to repair the issue, though repair order not clear what they did. On 10/5/13, same issue. Service engine light on, and car hesitates and vibrates upon acceleration. Per service invoice, "improper connection pin fitment". Dealership replaced fuel injector, and said problem solved. On 1/16/2014, same issue. Car shuttering upon acceleration btwn 15-45 mph, and engine light on. Dealer replaced transmission, and once again, told me problem solved. On 3/24/2014, while driving on turnpike, same issue. Car vibrating upon acceleration, and engine light on. Had car towed back (approx 170 miles). Completely unsafe to drive. Dealership replaced engine control unit and engine chassis (I think that's the correct name), and was told - for the fourth time - "problem solved" (though incredibly, the dealer refused to pay the tow charge). In total, I've had the car only approx 8 months, and so far, have had the fuel injector, transmission, electronic control unit and engine chassis replaced, causing the car to be in the shop for this problem a collective total of approx 25 days or so. The car is dangerous to drive and someone is going to get seriously injured. I have now seen other similar reports and complaints about this particular car, under the "complaints" section of the NHTSA. Something needs to be done.
