Welcome to the forum...…..
Buyers remorse or as I call it 2nd thoughts is very common and I get them also.
* Transmission issues were fixed mid 2015 production with a new hardware fixed ZF. No more issues to date.
* The KL platform is a new platform for the new Cherokee. The KL is a totally new type of SUV that is basically a computer on 4 wheels.
It also has a unique drive train and 9 speed transmission that sets it apart from all the others and other brands, in my opinion.
In my case I drove it first, a 2014 Cherokee, and loved the way it drove and handled. It just felt solid. I had a '04 Grand Cherokee SE V8 at the time.
I did compare all the interior area like seating and had almost as much room as the Grand. I factory ordered it as I could not get the options I wanted on the dealer lot. I absolutely wanted the Full Tech group and tow group.
For me there was almost no difference between the two in function except rear cargo storage and the '14 being loaded with more tech.
Towing was great with the '14 as it was with the Grand.
How it compares with my 3 older Jeeps, both '92, 2001 Cherokees, and an '04 Grand Cherokee simply said it does not in any way.
Its far better, more solid and road quiet than the other ones. It also is more stable due to the stability controls built into the vehicle.
I have never looked back at that early purchase of my 2014 Cherokee. Also glad I picked up a Max Care Life plan on it as I will keep this one a long time.
