Bought my V6 AWD July 2017. Had no problems, average mpg around town 19-21, highway 24-25. Lots of power. I previously had 4 cylinder FWD journey and had worse mpg and no power.
October I began to notice a slight decrease in the mpg's nothing major. The colder it got the worse it got. To the point of driving on the interstate where I would usually get about 24+ mpg, I ended up with 13.9 and it sounded like the whole exhaust system was going to fall off my car.
Brought to the dealership, they changed the air filter and said it was good to go. None the less, leaving the dealership the vibration, lack of power, and rattle where all still present. I have been bringing it to the dealership since December 12th. Just brought in yesterday 2/21/2019.
So the resolution from the dealership in my area was ... If I need more power going uphill (as that is when the bog down is significantly noticeable) I was informed to utilize the +/- on my shifting column to down shift to gain that extra power needed. Well, I may be a female, but I am not a dumb person. That is completely unacceptable from a dealership. This complaint has been recorded with Chrysler FCA as throughout this process I have been in contact with them as well.
They have legit not changed a single part on my car. Only advise to me that there is nothing they can do for it. I have to accept that after almost 2 years my performance and mpg's have all the sudden changed, and that it the way it will be.
They did find that under the hood, the ECM was banging against the frame (causing a rust spot) so they corrected the spacing, and are hopeful that at least the rattle will be subsided. However, it still makes the noise.
I questioned from the beginning the catalytic converter - but was told because there is no check engine light that can not be the problem. I had experienced 2 instances of smelling rotten smell within the vehicle, the loud (penny in a tin can sound) rattle, and the reduced mpg's. However, they disagree. So after literally doing this since December I asked yesterday about the ECM being bad ... and if they checked that. They advised again, nope its not that, just the way the car is. He can not explain what would have changed in the last 3 months but its a non fixable item.
Does anyone else have this problem, experience/knowledge, or had this fixed??! I would LOVE input!
My car has 47,700 miles - Still has several components covered under factory warranty. I bought another warranty that covers it until 125,000 and its got a certified pre-owned warranty until 100,000 miles ... yet no one will try to rectify this! HELP!
