I am starting this thread since a lot of owners of hr16de cars (micra/march, versa sedan, tiida sedan and versa note) in south america, mexico and canada are having engine fault.
The fault is a rod knock since car is brand new, is not a sever red knock, only audible with warm engine and light throttle.
I will le you the steps to perform the rod knock test and videos showing the problem.
STEPS TO TEST THE KNOCK:
1) Car in Neutral With Park Brake On.
2) Start Car, idle to normal operating temperature
( 20 minutes).
3) Place smart phone/camera/audio recorder on ground under front bumper near oil pan, recording
4) Slowly press accelerator pedal to 2500 rpm and hold, then depress slightly until rpm drop to 1900, and then press again until 2500rpm.
5) Repeat step 4 a few 10-20 times, rpm increase and decrease must be very slow, with very light load on throttle.
6) share video/audio.
Official nissan explanation to this problem (in spanish, paper came out nissan factory in aguas calientes, mexico), it seays is a rod knock and repair procedure (replace pistons, rings, barings, rods, etc).
On canada forum, some people had their engines replaced and new engines are knocking again.
Also some cars knock since brand new (like mine, and other memebers) and another we think yes, but owners only noticed the knock after some mileage (because tends to get a little worse) and others because they saw post on forum, made the knock test, and found their engines were also knocking.
nissan march less than 1.000 km:
nissan micra less than 700km:
nissan versa note, 190 km:
nissan micra, 40k km (start video at 2.35):
nissan micra, 36k km (start video at 1.00)
same micra with new engine, 1500km on new engine, nissan said new engine has to be replaced, as you can hear, it knocks a lot less than the old one, because knock becomes worse with mileage, start video at 5.40
i know a guy in stataes that has his versa engine replaced at 35k due to the knock, and new engine started knocking again at 15k miles, the guy sold the car.
So plase perform the test, and share your experience.
