    Default Gen 1 wind buffeting kit installed - Bulletin PI0642

    Finally got around to having the wind buffeting kit installed. 2012 Volt w/59K miles. Dealer covered the cost
    PI0642C is the code for the current kit.

    The kit consisted of upper (paint to match) and lower mirror covers & the black applique that mounts to the door next to the mirror.

    Tested the fix on the way home, HUGE improvment. Now it's like a normal car with all four windows down at speed. Able to drop both back windows down and leave the front up without the horrific noise.

    Nice! My dealer currently has the parts out for painting. I am excited to get these installed as the warmer weather arrives.

    I found that the only time this buffeting kit doesn't work is if you have a stiff side wind that counters the effect of the deflector. But other than that, it works great most of the time.

    And I'm out of line for the model 3, so people with at least 115k registrations before them are one step closer

    If you don't have the money, don't buy it.

    Could you please provide a picture from above on the mirror ?
    I would like to replicate the "bulge" on my 3-D printer to see if it makes any difference.

    I refuse to provide a picture of a buldge to a random person on the internet.

    Let me see what I can do over the weekend

    Don't forget about the black applique opposite the mirror.

    Is the kit free for the asking at the dealer?

    It is not standard due to making more drag and less efficient movement through the air. With them on is there any noticeable loss of range? Doesn't seem there would be but there was a reason not to put them on.

    It's my understanding it is dealer discretion. GM doesn't pay the dealers very well for this fix.

    I'd bed the reason it's not standard is due to cost. I have no doubt any 'drag' or 'loss of range' is negligible at best.

    While it looks a little goofy, the improvement is WELL worth it to me. I finally had a chance to drive with all four windows down earlier this week during my commute home. The sound was horrific. It was even horrible when I reviewed the dashcam video later that night.

    This wind issue is certainly not limited to the Volt, but I am very glad they have this fix out there for sure.

    When the dealer installed my kit, I only got the deflectors on the door side, not the mirror caps. I can report that it works. I don't know anyone with a volt near me with the full setup so that I can compare my ride with theirs, but if you are experimenting, I'd say do the deflectors first before the mirror caps.

    I had always wondered what it looked like.

    Thanks for the nice photos!
