2005 NISSAN ALTIMA with 156000. miles
I was waiting at a traffic light to turn green and when i started going and my car made a loud noise so i thought somebody hit me. I got out of the car,but no hit to my car. I thought that was weird because i didn't know what happened. It didn't happened again until a few months later. Most of the time when i start driving i hear a boom sound and i feel that my engine is going to break down. It feels like my gears are not connecting from first to second or if the transmission is not connecting with my engine. If i start driving and then i speed up, my car makes the boom noise. The same happens when i'm coming down the road at a regular speed and i slow down because traffic is slowing, but then we continue at the regular speed my car makes the boom noise like the gears didn't connect. My car is an automatic. I took my car to my mechanic and he told me to check with Nissan for any recalls because my car gave him a motor code P0726 which has to due with the motor's crankshaft. He told me that my engine and transmission are not connecting. I search to see if anybody else had that problem and it has been people complaining about the same problem, but no recall has been issue for this problem. Hopefully there's a recall soon to prevent any accidents due to this problem.

2005 NISSAN MAXIMA with 101000. miles
While driving my 2005 Nissan Maxima the gears slip and jump into gear with a violent jerk that is affecting my driving and may cause me to lose control of the car and possible injury myself or others. There is a transmission issue with the valve body that is causing this violent shifting and it seems that i am not the only one that has this issue. It is disgrace that the nhtsa had done nothing to address this wide spread issue, must people die first so it does get addressed. I will also contact my state representative to report the issue. I opened up a case with Nissan consumer affairs with no luck or admittance of their failed component. Nissan dealership diagnosed transmission with a P0726 code and had an open technical bulletin ntb11'035 which is acknowledgement of Nissans failed design of the transmission valve body. Nissan has quoted me over $2500 to repair their failed design component.
