Hi guys, don't bash me please if my questions bellow has been addressed before. (if there is already an answer, please provide me with the link so that i could read it up)

So, to start things off, this is not my car. Thus, I do not get to drive it every single day. My wife went overseas for 3 weeks and this is my very first time I get to drive it on a daily basis. I decided to do so as my wife had been complaining about her car since the very first day she got it from the dealer (since May 2015).
1st issue, for a 1.6 liter engine; the car is surprisingly slow to pick up from 0km/h to let’s say 10 to 15km/h. Coming out from a junction is a huge struggle and I felt that this car is putting me on a life threatening situation. My sis had a spare 1.6L Saga BLM(2012) for her employee and this thing works perfectly like a gem. I do understand that my wife’s Iriz is running on a CVT gearbox, but is that what’s causing this car to struggle under low speed? I realized that if it’s cruising at 60km/h, it’s quite easy for me to push it to 120km/h. However anything beyond that is a struggle again! The max that I can push is 160km/h. I can easily do 160km/h with my mom’s un-mod 2013 1.3L auto MyVi! I know this is not supposed to be a fast car but I do test whichever car that I manage to come across to the best of their abilities.
2nd issue, fuel consumption. Unlike me, my wife is a very smooth driver. She do not accelerate as hard as me and she rarely drives up to 90km/h. Normally, she likes to cruise between 70-90km/h as that is the speed that she is comfortable with and she only drive to and fro from our home to her work place. We tried both RON 95 and 97, full tank at about 32-33 liter and the max distance that she can go for is about 350KM. When I’m driving for the past 3 weeks, it’s even worse.
3rd issue, the head unit. The head unit always reset it’s time to December 1st 2013. Audio quality is crappy as well, especially when the base is supposed to kick in, but it doesn’t.
Other issues that has already been addressed;
1. Driver side and right rear door power window
2. Horn issue
3. Steering buttons
4. Steering horn button
5. Dashboard issue(dashboard got replaced entirely)
6. Headlight not able to turn on with auto being set at the lever
7. Right side DRL

thanks for your reply. It did not jerk actually..the only problem that i face is the power is too slow to kick in..

not that i wanna compare it to an imported car..but how come jap's car running on CVT gearbox don't have this kinda issue(LOL)?
