Looks good, did they let you keep the old skull cap? Where did you get the blind side mirror? I always have to roll down two windows to offset the buffetting, even then i don't roll it down all the way.

my biggest complaint with the Volt has been the horrible "air hammer" acoustic resonance a speeds over 40 MPH, yes you can configure the rear windows to cut it but it was really annoying to my ears.

I'll be stopping by my dealer tomorrow, is this another Customer Satisfaction enhancement?

I can't thank you enough for sharing this and GM for addressing this annoyance.

Regarding the skull cap, the dealer had to keep it as part of the warranty action. I got the little convex mirrors at Pep Boys, they really don't work that well as you have to "refocus" on the mirrors for them to be useful, but they are better than nothing.

In regards to the question of is this a Customer Satisfaction enhancement? I believe the answer is yes, I was not charged for this change. I believe the information on the mod is in Service bullitin B6804 9090. The new mirror kit part number is 22778043. The dealer has to paint the skull cap to match the car.

keep your windows up

The reason for the thumping is that having open windows really messes with the aerodynamics of the car. Much better to keep the windows up and the A/C on.

How does it look further away or maybe front of car view. I'm trying to see if the plastic on the A pillar is a bit aftermarket looking or if it blends in nicely.

Great information.

It's worth noting that the replacement skullcaps are less aerodynamic. Which is why they reduce the buffeting. Worth it for some people. But if it doesn't affect you, you're better off with the originals.

I agree. I don't know what's worse, the mods or the fact that the windows are open, but aero efficiency is definitely reduced. On the other hand, you only live once, so if you enjoy driving with the fresh air blowing through the windows, than I say go for it.

 

[dwl]

Myself, I often drive with the front driver's side window all of the way down and the rear passenger's side window cracked maybe 2 inches. That completely elimiates any buffeting for me and I find it to be more than enough airflow. But I rarely drive with my windows down on the freeway. I try to keep my windows up once I hit about 50mph because that's about when drag really starts to affect efficiency. 45 and below, I enjoy the breeze and any minor losses that come with it. Maybe at 70mph it'd be a different story and I'd still experience noticable buffeting. I'll probably give it a shot next time I drive that fast.

I have a thread on this kit to address wind buffeting with the window down somewhere from a while back. According to the bulletin unfortunately this kit IS NOT considered a product enhancment,nor is it a campaign, but instead considered an accessory kit and as outlined by the bulletin only as a "customer pay" repair. (similar to the higher air dam)

However, if you had previously raised this concern with your dealer, (hopefully ON a previous work order) they may just call it in and possibly "goodwill" it. No guarantees though.It cannot even be claimed under warranty technically. (the warrantly claim will just be rejected)
So I suggest you speak with your dealer and see what they can do.

larry4pyro, does Volt require 1 mirror kit for each mirror or does one kit cover both mirrors.

 

[lsteiner]

Where did you get the Blind Spot mirrors. They look great!

Not sure. My dealer ordered the parts and installed them at no cost. The parts consisted of new covers for the mirrors, which had to be painted to match the car and new plastic front window trim pieces. I'm impressed with GM's customer service, the modification works well, and I have not seen any significant reduction in range.

Pep Boys, don't remember how much but they were pretty cheap. The mirrors work OK, but require that you refocus on the tiny image in the mirrors.

I had this modification done to my 2013 Volt as well. I always drive around with my windows down when it's warm. I must admit though this modification does create a little bit of wind noise when the windows are up cruising starting at 45 mph and up. It's not very bad but I can def. hear it. Worth mentioning to those considering this modification. For me, it was totally worth it though.

 

[Sterling Silver]

This is sort of frustrating, the modifications and enhancements that GM puts out for the Volt, but does NOT COMMUNICATE to owners.

Even people who own really old airplanes get a letter from Cessna-Piper-Beechcraft etc. if a mod is needed, but GM and the dealerships don't communicate to us about battery mods, level 1 cords and now this. Am I missing something here, or how do we get on a mailing list for Volt fixes?

Here's a link to my EV World blog that I thought would be of interest for this topic:

[I-HATE-OPEC]

Does anyone know the GM part number for these side mirror fixes to prevent the wind thumping?

My dealer is lame and insists that it is NOT a chevy part and is an aftermarket part.

PLEASE HELP!

I have a 2012 and I'm looking into the mirror upgrade. Did you notice much in the way of degredated distance? What is this battery enhancement you're talking about????
