I feel for you, I got rid of the car last week. I've had many Ford vehicles and this was my first Lincoln. Pretty sure it's my last of both. Couldn't stand to hear that tinny, poorly setup system any longer. My new car is playing the same USB drive that I had in the MKZ and it is amazing!I My long commutes are happy once again. That alone wasn't the reason for only keeping (dating) this car for two months. Some others are:
Poor trunk design, if it's raining, prepare for water rolling over the sides into the trunk. I had to reprint some documents due to this one day. Bending over to hit the trunk release is also horrid. If you have a backpack hanging of one shoulder and the other hand full, prepare for it to take a ride. What's the point of keyless everything if you still need to fish the keys out of your pocket?
Sunshade on the sunroof (small one) seemed to always work it's way partially open, nothing held it close. Could have just been mine.
Couldn't easily change temp without looking down, even worse with gloves on. No feel on the buttons. I know I could have done it from the wheel, but too many clicks to get there.
I had the hybrid, during my test drives the gas engine was ok on noise levels. After a month I hated the drone of it when it would kick in, which was often.
Operating the heated seat from the touchscreen would frequently end up with the cool being turned on first, the buttons are too far away from the driver on the home screen and too close together. I program HMI's, adding a little space goes a long way for the operator. I know the climate screen is laid out differently, but again, too many button clicks.
The push button trans, while allowing for a more open cockpit, was frustrating. I would frequently get yelled at for the car not being in park because I hit the off button too quick. They are right next to each other.....
Glove box was tiny, I admit I never checked in before hand, just didn't think such a large vehicle would have such a small one.
There's probably more I could complain about, I honestly really liked it on my two test drives, one being over an hour. I hated it after a month. Buying cars is like dating I guess..... LOL
I was fortunate that I could walk away from it with no real loss. I did the VW TDI buyback and used a good portion of that to put on the Lincoln, I was able to walk away from it with some VW cash still and got a 2017 Passat. I guess I'm a VW guy now. LOL. About the only thing I miss about the MKZ is that the key fob would tell you if the car remote started. Not that big of a deal.
If you can get some decent bass in the car I think you'll be happier. When I disconnected the rear door tweeters and set the fade more rearward, sound improved overall. I reconnected them before turning it in and it was back to misery. I had though of running an amp off of the rear channel and putting it right back into the subs and boosting the gain. 6x9 subs are not easy to find, but I thought that would shore up the weak lows.
