  1. Electronics problems

    Did you ever find out what it was? My 19 SI started doing this exact same thing last night. I've seen a few videos on YouTube that are saying it's a programming error in the computer system but wanted to know if possibly it was something else.

  2. Engine backfires and Warning Lights 19 SI

    I was able to get it to a dealership without turning it off. This was the scan sheet. They said it was over revved at some point in time to create the P0219 code. They cleared it and said not to drive it hard if I'm not in Sport Mode. Does this make sense? The first time it happened my roommate...

  3. Rattling Noises from engine compartment or under car

    Check to make sure your hood bar is locked in place. If it isn't it will raddle against the frame and make a noise at different RMPs

  4. Engine backfires and Warning Lights 19 SI

    Update: It did it again and again last night. Still no codes left behind for a lingering light but was about a quart low on oil. The last oil change was about 2k miles ago. Additionally the vacuum cleaner exhaust tip is covered with a black gunk. Im thinking its most likely its something to do...

  5. Engine backfires and Warning Lights 19 SI

    Do you know if there was any engine or ECU code for that?

  6. Engine backfires and Warning Lights 19 SI

    About 2 weeks ago I relocated from Charleston SC to Pittsburgh for work. I'm only going to be here for a few months. As far as fuel goes premium in SC is 93 and around here most places have 91 its hard to find 93.

  7. Engine backfires and Warning Lights 19 SI

    My neighbor owns a shop with and has a pro scan tool and he's going to check it out when he gets home. I was pretty sure that there was a history on the ecu that can be looked at.

  8. Engine backfires and Warning Lights 19 SI

    About a week ago my roommate took my SI for a quick trip to the store. He said all the lights came on on the trip back. We both went out and started the car and nothing. Today on a trip to Home Depot it happened again. I recorded a video of it happening and turned off the engine and went in the...

  9. I'm really.. really new here.

    First thing is I wouldn't do anything until you let the car break in. Even KTune suggests 5500 miles as a break in before reprogramming the ECU. Also know that most aftermarket mods will void your warranty. Audio There are several ways to do this. Basic speaker upgrades and add a more...

  10. Lower than expected MPG

    Just got 40.8 MPG driving 80+ on a work trip to NC but I normally get about 27mpg driving around downtown Charleston SC. All stop and go.

  11. For Si Owners Only: Si vs. Type R --- Would You Give Up Your Si, if Type R was Available for MSRP?

    A Type R wouldn't work with me. I drive 50k miles a year for work and my SI makes it fun. It's not uncommon for me to come across a NC back road and push the spot button some fun. The type R is too low for daily driving or my work. I wouldn't want to ruin the body kit.

  12. Si owner demographics and modification schedules

    38 Engaged Father of a 2 yo. I make a decent living and have a 15 Jeep as a daily/work vehicle. Just bought my 19 SI about a month ago but eventually it will end up being a Daily/Work vehicle too. As soon as my Jeep has 177k miles then my Jeep becomes my project car and the SI takes its place...

  13. SI an old Geeezer car

    My insurance was only $63 a year difference between a 19 Touring and a 19 SI. However if it was an R it would have been about a $300 difference. It actually costs me more to insure a 2015 Jeep Cherokee than my SI

  14. SI an old Geeezer car

    I'm 38 and the woman is 27. She likes riding in my SI being that she can't drive a manual, (and wont learn.) All of her sub 30 year old friends love mine and also cant drive a manual. So maybe all the old geezers figured out if they want to bang sub 30yos... buy an SI...Dont be jealous they...

  15. Anyone install aftermarket headlights? I hate the stock headlights on the si

    Can someone with before and after pictures of the HID and LED lights post a picture? Bought my 19 SI a few weeks ago and the yellow lights have been bothering me since day one. Mostly want to see what the HID looks like vs LED. (Spending $120 vs $1200 to upgrade)

  16. '19 Si Coupe Speaker Upgrade (worth the money?)

    The woofers are fine but they need insulation. The tweeters suck. Even a low end tweeter would sound better. You won't get good lows from an 8" without a box but they do make small boxes. Go 10" .75cf sealed if you are worried about space but keep it mind a sealed sub requires more power for...

  17. '19 Si Coupe Speaker Upgrade (worth the money?)

    I'm curious to know what year is yours? Was it the 6 speaker base or "Premium" 8 or10 speaker and if so was the head unit you swapped out was pre or post refresh? Was it the new one with the knob? I analysed the sound curve coming from my neighbors about a year ago on his 2017 when I did his...

  18. '19 Si Coupe Speaker Upgrade (worth the money?)

    I just bought my 2019 SI last Thursday and spent Saturday putting a Alpine Type R12 subwoofer and insulated the rear deck and doors. I used an old Alpine MVR-500 I had and ran directly to the high level inputs. I took out the useless 8inch and tapped into those wires leaving the hole for sound...
