New update.
Yesterday I went to check out my buddies car, had him drive mine first and he commented that mine feels a little tighter, the power rolls on a bit differently, it's smoother and the rear doesn't squat as much but it requires you to push the pedal to the floor to hit the switch for it to downshift and give you the power. He summed up the experience as more refined. When I drove his, I focused more on the steering and overall ride quality feel. Not an exact test as I had winter tires on 18" wheels and he still had the 19" summer on his garage queen (1600 miles in almost 5 months) and it was 60 degrees out and the tire pressure was 45/47 (F/R), which sort of made it feel a little firmer. I felt the ride was close with mine feeling slightly better and I commented it might be the tires but he thinks overall the 2019 feels better. Noise level was similar with regard to cabin quietness, shows that my old car had more than just the bad door alignment issue, which they corrected but still the car had that buffeting sound, which was not present on either his 2018 and my 2019. What we did agree on was that the rear end felt tighter on the 2019, so I decided not to install the rear sway bar at this time.
What we did find however as being a big difference was the audio system on the 2019 was massively better than the 2018! I equate my old 2018 to sound similar to his. At level 10 on mine, his would need to be around 17. At max level in his, we could still have a conversation and hear each other, on mine at max, you don't want to be in there at that level for too long and even standing outside with the doors open, we couldn't hear each other. I did note the my 2017 Optima was louder than the Stinger and his 2012 system was close to the 2019 in volume but man, that thing had massive bass! The Infinity system in the 2012 Optima Hybrid was known to have a bass heavy system and this experience reminded me how I had to tune mine into the negative to balance it out. The overall sound quality on the 2018 is best described as muted, while the 2019 at flat tone settings sounded great across the board, you had to tune the system a few levels up at 17 to get it to be close to the 2019. He also mentioned he had some issues where his audio would get stuck at a low level, told him about issues mentioned on the board and advised him to get it looked into while the car is within the 12 month/12k mile adjustment period.
From this, I can say, my 2018 was certainly had some issues and while others didn’t experience the same, this seems like things KIA needs to have their factory folks or those doing final checks pay closer attention to. With the G70 experience fresh in my mind, I feel my 2019 isn’t far off from that car and I suspect neither are a lot of 2018s that are just as good all around, including the sound systems. With dealerships being the face of KIA and the only experience a lot of people have with the company, they really need to put effort into making sure their knowledgeof the product, and how they treat their clients are top notch. Even with the issues my 2018 had, which were minor annoyances at most, I still enjoyed driving the snot out of that car. Now I can enjoy the Lexicon system in my car, they way it was meant to be. Yeah, I know they brand it Harmon Kardon on the speakers but as been shown by others modifying theirs, the amp is in fact Lexicon. I just crossed the 1k mark on the car and looking forward to many more miles with it on the road. Yeah, some times I just go in the garage and listen to the stereo as it’s sounds so good now.
