Arrow Engine farting noise; Transmission jutting @ low RPMS; Power distribution issues.

A lot of strange things have been happening to my 2013 nissan versa sv sedan with 73,000km the last few months. Just some info:
  • Recently I ran my car into another persons bumper at very low speed. So low in fact his bumper was completely undamaged while the corner of mine cracked and broke off exposing the washer fluid tank.
  • The engine light is on.

The farting noise:
When starting the vehicle the initial burst of RPMs you can hear an additional "farting" noise that tags along the normal revving sound. Once I get going it still remains, though you can hear it more the higher the RPMs. On the highway for example going 100km/h if I have to speed up you can hear the farting acceleration noise. It sounds rough like there's a part of my engine exposed that shouldn't be. Exhaust leak?

Transmission jutting:
While in drive if I come to a complete or near complete stop, there's probably a 50-75% chance the RPMs will dip into the 500 range and cause what can only be described as a jutting or seizing/stalling of the engine except it doesn't stall. It will just jerk for a moment or two and remain running. My theory on this is it could have something to do with a computer controlled routine not activating properly considering the RPMs go so low. If I shift into neutral during the stop it never does the jutting. I have also noticed that if I shift into neutral and then drive again when the light turns green, it will sometimes take an extra second or two to shift properly so that could indicate transmission or power problems?

Electrical anomalies:
This ties in to the previously mentioned problems. After the light accident I described above since then I have noticed weird power anomalies. The left rear light cluster is now only 50% of the brightness of what it should be. The right rear is normal while the left rear is dim. I'm not sure if the left front headlights are any different from the right front. Another anomaly is when I start the vehicle the display panel showing which gear I am in will work just fine, but after shifting and driving for a short while it will go blank and won't display any gear at all. I bought the vehicle new in 2013 and the battery is still stock.

Conclusion:

All these problems have started up in the last 4-6 months, and I am very perplexed on where to start. Some have told me to change my battery, others have suggested it might be sensor related etc. I'm just wondering what direction I should start in.

thanks

That "extra" noise you describe could possibly be an exhaust leak, or some type of muffler damage. Needs to be put up on a lift for a good inspection.

Not knowing were you live, the fact that you are quoting your "mileage" in Kms would lead me to believe you live in another area other than the United States which changes the layout of your front end, right hand or left hand drive. If you sustained the type of damage that exposed your washer fluid tank, you took a pretty good hit. The "jutting" you describe may be caused by your transmission. I have a 2012 Versa sedan with a cv. transmission. The car was parked, and a motorcyclist ran into the drivers side fender just behind the front tire. Shortly after the car was repaired by the body shop, I experienced the type of behavior you mention.........I would be stopped at a light, and the car would just "jut" forward. Put the car in neutral and it was fine. I did have a "Check Engine" light on, so, still being under the power train warranty, I took the car to my Nissan dealer, and it turned out to be the "Control valve" inside the cv transmission. They ended up replacing the entire transmission under warranty, and that jutting disappeared. From what I understand this "Control Valve" is the brains of the cv tranny, and can cause major issues. As far as the electrical issues the only thing I can suggest is to check the various fuses to make sure they are good. With all the electronics in the vehicle, there are many control modules that cannot be checked without dealer software. Hope this helps...................
