For the passed week or 2 I'd say maybe a handful of times my car has bucked going up a hill...it's automatic and it's not throwing a CEL so it's bugging me out. My only thought would be maybe i need to change tranny fluid? Thanks.

 

What year and how many miles?

 

Fuel starvation??, how low was your tank?

 

09 g37x sedan with a little under 65k and wasnt low on fuel...havent done much but changed the oil since and it hasnt really dont it but also its been 40+ degrees and when it was bucking, was when it was very cold out....idk we'll see when the temp starts to drop again

 

For whats its worth, this is normal at least when I had my car. It was on certain RPMS and light acceleration. I blamed it on my berks HFC, but who knows. Infiniti techs claims they never found an issue
