Hey guys -
New to the forum. Looks like a ton of content on here - looking forward to it. I bought a new Grand Cherokee from a dealer here in New England about a month ago and it's already been back to the dealer a few times in the first 1k miles. Mostly minor stuff that I can live through while they fix (glove box falls open, tailgate doesn't shut properly, windshield washer fluid "tank" came with a huge hole in it) but there is one where I want to make sure I'm not crazy.
The one I'm curious/worried about is relative to the transmission. I noticed it immediately when I picked the car up and even drove it immediately back to the dealer after less than 1 mile. Whenever I get above ~15 mph, when decelerating to a stop (coming to stop sign, red light, etc), the transmission has a subtle jump during the downshifts at 8-9 mph and 4-5 mph. It is not an aggressive jerk but it is noticeable 100% of the time. When I took it back to the dealer on the day I bought it, the service manager came back out with me on the road and also noticed it. He felt that it wasn't normal and we turned around. After a few minutes back at the dealer, he told me it was in fact normal and that as the computer learned my driving habits, it would go away after 500 or so miles. I now have 1,500 miles on it and it's still there, same as the day I bought it. I had to take it back to the same dealer to fix the washer fluid tank and I asked them again to take a look at the transmission given the issue wasn't gone at 500 miles like they said. I had to leave the Jeep for the day and they took it for a 17 mile ride to confirm that nothing was wrong with it! This time they told me that they meant to say 5,000 miles, not 500.
For a number of other reasons (including the 17 mile situation above), I decided I was done with this dealer and took it to another one today. They took it out for a ride (without me) and said they didn't notice the jerk - they did echo the same sentiment that the transmission/engine is still in "adaptive mode" for the first 3-4k miles where it does learn my habits and maybe/hopefully it'll go away at 3-4k. I'm not crazy on the jerk - while subtle, everyone who has ridden with me has acknowledged it.
I wanted to check in to see if anyone else has had this issue with the 5.7L V8 in the 2020s. Anyone have this or have any insight?? I appreciate it!
