2 months ago bought a 2010 Explorer in the Middle East ( Odometer currently @ 3000 Kms). After @ one month of purchase, drove a long distance (Odometer then @ 1800 Kms), when reached the city and began driving slowly, felt as if the car was hit from behind very strongly when shifting from 1st to 2nd gear. This happened once. But since then, frequently feel hard shifting to 2nd and 3rd gears, and frequent strong sound when shifting between 'P', 'D' and 'R'. Also, feel a bump when coming to a complete stop. Since I got the car, I also hear noise in rear wheels. I can’t believe all these problems in a new vehicle. I will appreciate your answer/advice. May be I should have bought a Japanese.

I don't know if you have the 5 speed or 6 speed automatic...but i'll suggest some things anyway. My first thought is that there may be a calibration issue with the transmission control. Software updates are fairly common, and with that transmission, may make a world of difference. If software does not fix it, you probably have an issue with the mechatronic assembly inside the transmission on the 6 speed, or the shift solenoids / valve body on the 5 speed. Regarding the noise -- is the noise a tire noise perhaps? You could have a rear differential noise, but I would find it abnormal at such a low mileage myself. Nonetheless, if bearing preload was not set quite right at the factory, or the ring and pinion wasn't set up right - you could have noise. Best of luck!
