yeah so the other day i was drivin down the highway and the car just stalled out an wouldnt start back up....i brought it to a dealership they said it was the coil pack...they fixed that and now its running like **** an blowing out black smoke and the dealership said they dont know why...anyone have any clue?

 

This just shows how poor Nissan mechanics are trained. Getting the answer
you did isn't an option from any dealership. Take it back, let them know you
want your car fixed and running like new. Sounds like something is wrong in
the wiring, coil packs to spark plugs. Don't accept the car until they get it
right, that means zero misfires/black smoke....

i'll agree with this

 

i know thats what i did...i mean its at 3.5 vq...they put this engine in like half their cars u think they know it well enough by now right?

 

You don't know dealerships.

80% of the mechanics that work at dealerships, are barely up to the standards of working on the cars they do... (my percentage, I think it seems fair)

 

this happened to me b4 i was on the highway and i pressed the gas and no response so i pulled over luckly my car started up again..but went to the dealership and they said it was my bad throttle body..so they replaced it

 

its funny how almost everyone on this site hates the stealership lol..

but yea man thats too bad.. sorry to hear that.. i agree wit gary as well.. if its under warranty.. make em fix it..have fun wit ur loaner
