2013 Infiniti JX35 acceleration problems

Filed Apr 15, 2025 · Acceleration, Engine · CA

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.

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.
