2013 INFINITI JX35 Engine 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.

The contact owns a 2013 Infiniti JX35. The contact stated that the engine warning light was illuminated. The vehicle was taken to the dealer, who informed the contact that the transmission fluttered and needed to be replaced. The vehicle was then taken to an independent mechanic, who informed the contact that the transmission fluttered and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure and referred the contact to file a complaint with the NHTSa Hotline. The failure mileage was approximately 163,000.

My vehicle started jerking and would not gain speed while in traffic while I was dropping my children off at school. I took it an Infiniti dealer to learn that there is transmission failure.

When I accelerate the car, its feels like the transmission shudders. Feels like I am driving over rubble. Don't know if this is what they call Gear slipping or transmission slipping. Happens in ECO and Standard mode, have not tried it in sport mode. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

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.

BROKEN O-RING SEAL BETWEEN TRANSFER CASE AND CVT ASSEMBLY - TRANSMISSION FLUID LEAKING FROM TRANSFER CASE SEAL - THIS CAME UP AFTER 5YEARS OF THE CAR - JX35 WAS THE FIRS MODEL AND HAS MULTIPLE DEFECTS AND I BELIEVE THIS IS ONE OF THEM AS WE DO NOT SEE ISSUES WITH TRANSMISSION THIS CAME UP AT SERVICE CHECK

I HAVE COMPLETE TRANSMISSION FAILURE ON MY JX35 INFINITY, AND THE VIN NUMBER IS NOT LISTED. NISSAN AND INFINITY ARE AWARE OF THIS ISSUE, BUT IN MY OPINION, IS NOT COVERING ADDITIONAL VEHICLES TO SAVE MONEY. I HAD THE VEHICLE IN THE SHOP MORE THAN 3 TIMES AFTER PURCHASING IT USED FROM INFINITY IN 2015 WITHIN 3 MONTHS TIME. APPARENTLY, THIS WAS JUST THE BEGINNING OF THE ISSUE WHICH I AM NOW LEFT WITH. THE RECALL NEEDS TO BE EXTENDED TO COVER ADDITIONAL VIN NUMBERS THAT ARE NOT LISTED.

AT 106,000 MILES, OUR 2013 JX 35 WAS DIAGNOSED WITH TRANSMISSION FAILURE BY THE DEALER AND A PRIVATE CAR REPAIR SHOP. FOUND THAT THERE IS A SERVICE CAMPAIGN DATED 4/18 ADDRESSING THIS ISSUE FOR 2013 JX35 VEHICLES. OURS MEETS ALL REQUIREMENTS EXCEPT FOR VIN. WE BELIEVE OUR VIN IS ONE OF THE AFFECTED VEHICLES.

DURING THE WEEK OF DECEMBER 29TH, MY CAR HAD THE SAME SHUDDERING NOISE AS DESCRIBED IN SERVICE BULLETIN: TSB NO. ITB15-012D. THE NOISE COMING FROM THE ENGINE AREA SOUNDED LIKE A BAG THAT WAS BEING ON THE GROUND DURING THOSE FEW DAYS. I BROUGHT MY CAR INTO A LOCAL REPAIR SHOP, THINKING IT WOULD BE BRAKES SINCE THAT HAS BEEN THE ONLY ISSUE WITH THE CAR. HOWEVER, AFTER DRIVING ON THE FREEWAY THERE WAS A LOUD NOISE LIKE SOMETHING DROPPED ON THE GROUND AND MY HUSBAND WAS ABLE TO PULL THE VEHICLE OVER TO THE MIDDLE FORK OF THE ROAD AND THE CAR COMPLETELY CEASED. IT NO LONGER MOVED FORWARD WHILE THE ENGINE STILL RAN. WE HAD IT TOWED BACK TO THE LOCAL REPAIR SHOP, WHICH WAS DIAGNOSED AS A TRANSMISSION ISSUE. THIS WAS EXTREMELY SCARY WHERE THIS WAS A VERY BUSY FREEWAY AND THIS WAS CLEARLY A MECHANICAL DEFECT, SINCE I MOSTLY DRIVE THE CAR LOCALLY TO PICK UP MY FOUR CHILDREN. THIS SHOULD BE A RECALL RATHER THAN A SERVICE BULLETIN, WHICH ALMOST TOOK OUR LIFE WITH THIS MECHANICAL DEFECT.

THE RADIATOR FAN MOTOR STARTED MAKING LOUD NOISES AND SOON AFTERWARDS BROKE. THE ENGINE STARTED OVERHEATING AND I BARELY DROVE THE CAR TO THE INFINITY DEALERSHIP IN CORAL GABLES. MY INFINITY HAS 34,000 MILES, BUT IT'S BEEN MORE THAN 4 YEARS SINCE I BOUGHT IT AND THE SERVICE DEPARTMENT AT THE DEALERSHIP IN TOLD ME THAT THE FAN ASSEMBLY RADIATOR MOTOR IS NOT COVERED BY THE ENGINE WARRANTY. THE SERVICE ADVISER TOLD ME THAT THEY SEE SUCH DEFECTS QUITE OFTEN ON SIMILAR VEHICLES.

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. *TR

AFTER ABOUT 3000 MILES, I BEGAN TO EXPERIENCE A "BUCKING" OF THE CAR AT VERY LOW SPEED IN TRAFFIC (~10-15MPH). EXPERIENCED A LOSS OF POWER AND WOULD HAVE TO STOMP ON THE ACCELERATOR TO GET THE VEHICLE TO ACCELERATE. THIS BEGAN TO OCCUR REGULARLY UNTIL I DECIDED TO TAKE THE VEHICLE IN AS PART OF THE FIRST SERVICE. I WAS INFORMED THAT THE TRANSMISSION WOULD HAVE TO BE REPLACED AND THAT I WOULD HAVE TO WAIT FOR THE PART TO ARRIVE AND THAT THIS WAS A KNOWN SERVICE BULLETIN. MY DEALER HAS BEEN VERY ACCOMMODATING HOWEVER IT IS VERY UNNERVING TO HAVE TO REPLACE A TRANSMISSION JUST 5000 MILES INTO THE LIFE OF A VEHICLE. I AM ACTIVELY EXPLORING OPTIONS TO ADDRESS THE FINANCIAL LIABILITY THAT I NOW HAVE AS PART OF THE PURCHASE OF THIS VEHICLE. *TR
