Dealer call for pick up vehicle, and replace the 'instrument comb" and calibrate odometer. As of today 10/18/13. Vehicle still have shudder when in the speed of between 10-15mph, especially going uphill. Per dealer advise the Jx35 engine is cvt, no changing gear. But I can feel that the shudder is come from when engine change gear from fist to 2nd. No further solution dealer can be provide.

I had only owned this vehicle (Infiniti Jx35) for a few weeks when I noticed that in stop and go traffic and/or slow speeds (15-30 mph) the front end would shake and shudder uncontrollably as if the car was going to stall. The only remedy was to bump on the accelerator to get it going faster. This made for very dangerous driving conditions as you were constantly surging forward to keep the car from sputtering. Apparently Infiniti was aware of this problem prior to selling me this car as a technical service bulletin had been issued 7/13/2013. The bulletin describes the problem as a torque converter issue and recommends replacing the converter, which requires tearing apart the transmission, however after 3 days in the shop replacing the torque converter, the dealership (Infiniti of norwood, norwood, MA) called me to tell me that this did not solve the problem and that they would now have to replace the transmission. In a brand new car. . . Ridiculous! now I am being told that the transmissions are back ordered for 3-4 weeks and OH, by the way, there are 2 or 3 cars ahead of you waiting with the same issue. This is a very serious issue and in my opinion represents a breach of good faith by dealers selling these vehicles. My calls to the sales rep and the gm have gone unanswered for 5 and 3 days respectively. Buyer beware on these vehicles.

To whom it may concern, we only had this brand new vehicle about 3-4 weeks when it started to exhibit major front end shaking/steering issues when operating/accelerating the vehicle between 15-25 mph. This is a highly unsafe situation that could cause the operator to lose control of the vehicle. There was a technical service bulletin (itb13-020) issued by Nissan/Infiniti on June 12th identifying this as a manufacturing defect and impacting Jx35 vehicles manufactured on or before March 26, 2013. Unfortunately, the repairs required on this brand new luxury vehicle are extensive and involved major work to the power train (see detailed report below). Nissan/Infiniti had to know about this issue on or before March 26th since that is when they officially changed out the part(s) on the assembly line which is well before they sold me this vehicle with (known) major defects causing it to be highly unsafe to operate.
