2013 INFINITI JX35 Driver assistance Problems

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 own a 2013 Infiniti JX35 and the transmission failed on 1 July 2022. It was replaced by AAMCO in Irondale Alabama on the 8th of July. The transmission promptly failed on the way back to SC. during the failure, the FCW and BCI malfunction warning lights came on and the vehicle shuddered and loss power while I was on the highway. the check engine light also came on. I am now hearing that this is a common problem with the 2013 JX35 and the 2014-15 QX60 SUVs. Had I known about this issue, I never would have purchased this death trap. I have made a subsequent trip to the AAMCO here in Columbia, SC and they reset or cleared the codes and as soon as I got on the road to head home, they came right back and I loss power and the vehicle began to shudder again.

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.

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.

VEHICLE IS EQUIPPED WITH FORWARD COLLISION PREVENTION. WHILE DRIVING WITH CRUISE CONTROL ON, VEHICLE WILL OCCASIONALLY BRAKE EVEN THOUGH THERE IS NO VEHICLE IN FRONT. THERE IS USUALLY AN 18-WHEELER IN THE RIGHT LANE AT THE TIME. DEALER AND MANUFACTURER STATE THAT THEY AREN'T ABLE TO REPRODUCE AND THAT THERE ARE NO MALFUNCTION CODES. THEY INSIST THAT RE-ALIGNING SENSORS IS A MAINTENANCE ITEM AND REQUIRE PAYMENT OF $150 TO PERFORM THAT FUNCTION. THE DEALER ALSO STATES THEY AREN'T SURE THAT WILL FIX THE PROBLEM. VEHICLE HAS HAD ONE DEFECTIVE ICC SENSOR REPLACED AND MIS-ALIGNED SENSORS REALIGNED ONCE. *TR
