"Also im hearing a pressure-relief like sound...."

Could be just a case of bad gas after all.....

 

Only 1,200 miles....YIKE`S, somethin`s goin on there, git `r looked at brother....
Yes, i`ll stay tuned... i subscribed to this thread so i can keep an eye on what was found wrong.

 

Well here's the lowdown. They gave me a 'could not duplicate' on the road test and there were no codes showing up on the computer. Thing is, you've gotta be looking for the things i'm noticing and if you've got the radio on you're just not gonna notice it. Maybe it was just me? If it gives me any more problems going into gear it's def going back. They did get the K17 recall done for me though which is good..

 

Hi - sorry I new to this site and saw your message. My 2010 1500 4.7L is showing the same issues - especially with down shifting. Dealer "rebooted" the computer said it was driving habits - still not working correctly... Seems like it only does it when it's been warmed up - not colded. Did you get yours fixed and what was the result.

 

K17 recall...???? and what would THAT be (????????????)

 

Heater controls/reprogram/fix

 

That's when you insist they ride with you. I had a new '03 Camry (back in the day) with a vibration issue (ended up being a recall issue after I traded it), after three attempts, same BS "Can't duplicate problem" I did the test drive with the mechanic sitting shotgun. Got on the highway, hit 55 mph, and said "hold on" let go of the steering wheel and watched the Camry pull itself three lanes to the right in under fifty feet. Looked at the dealer mechanic and said, "Do we need to duplicate the issue again?"
