I just took possession of my new 2021 Commander Max XT and also have the full windshield. I agree, it is pretty hot after driving it for say 1hr in 85F. I removed the windshield and it made all the difference. In hindsight, I should have purchased a flip windshield but its too late now,, already too expensive. Besides fall is coming and that's the perfect time to drive these things.

We purchased ours in April with a full windshield and we have complained and done everything we can to see what they will do and they have agreed to let us trade our full windshield in for a power flip windshield which is on back order until October 15 maybe even later but that’s what we are going to do to get rid of the heat because we can’t stand it. Thanks for your reply

2021 Commander XT with glass windshield. Too hot to driver. Back to dealer two times. Covered lines in heat tape. Didn't work. Brought it back. Dealer measured air at 105 degrees coming out of shifter. Found 3rd party cover for shifter area. Still too hot. Added wind wings. Took doors off. Still too hot. Water bottle in cup holder too hot to handler. Dealer suggested drilling holes in plastic firewall behind tires to let air in. Ugh. Noticed if you keep speed under 15 mph there's no problem. Believe heat problem tied to air coming from radiator. Can Am has a major problem and since the power flip plastic windshield is on back order, they know about it. We bought our rig sight unseen. Lesson learned. Now our brand new rig sits in the garage. Any suggestions (other than taking windshield off) would be appreciated. If not, going to sell and get a General.

I have insulated the coolant lines that the idiots ran through the console with cool it by thermomtec , but it didn’t help much. My next step will be to relocate the lines into the driveshaft tunnel, which is where they should have been in the first place. What kind of idiots would redesign a side by side to reduce a heat issue and leave the main culprit for the problem in the same place ?

For me the heat issue is on the lowest priority over 1. Front Differential leaking, 2. Drive line rattle-vibration at 4600RPM and 3. for no reason the engine cut out once. I have had this unit for a total of 250 miles so far!! Been at the dealer for 17 days now for the front diff leak.

broken u-joint or any driveshaft failure, would likely lead to a major coolant leak by doing that "relocation". I'm not criticizing, just something to keep in mind.

The driveshaft tunnel has a protective shroud over the top of the driveshaft to protect the bottom of the floor pan from a driveshaft failure, I am confident it would protect the waterlines as well. Besides with regular maintenance and inspections I don’t worry about my driveshaft failing. At 68 years old I’m not going to be pushing my can am too hard.

This is my husband replying. I’m not smart at mechanics but hopefully our heat issue will be fine once we get the flip windshield

We have ordered a power flip windshield due to be here mid October. We took our full windshield out and there was no heat at all. We also insulated the console. This should solve the problem. Thanks for the picture !

Ive owned an older commanders and the heat in the cab was bad. I have ordered a new one and looked forward to the heating issue being resolved. Now I'm disappointed to find out its not. I am thinking this is similar to the dust issue. It pulls dust in when you have a windshield like most side by sides it creates a low pressure spot in the cab. A rear windshield always seem to fix the dust issue. I think this would work for the heat issue as well. It could be pulling engine heat back up the tunnel when the windshield is on. Did any of you install the rear windshield?
Id love to figure this out before I take possession of my new commander.
Thanks,

The heat issue is where they have ran the 200 degree coolant lines through the console just as they had in the previous years. We insulated our console ourselves but didn’t help that very much. We purchased the side wing vents and that lets a lot of air through the cab but still didn’t help with the heat issue. we took our windshield out and the heat issue was gone so Can-Am is going to let us trade in the full windshield for the power flip windshield and it should be here in October sometime. More money but we couldn’t live with the heat in the cab because they never fixed that problem from previous years even though they said they did. They lied !!!

I've got the Super ATV full windshield in front and the UTV direct tinted/vented window in the back. The back window didn't make a difference on the heat issue.

I previously owned a 2012 Commander 1000XT which was a great machine but the heat issues were horrendous! In May I purchased my 2021 XT and all Summer I rode around without any windshield as the PowerFlip was on constant backorder. But I was pleased in the fact that I had ZERO heat issues in the new model so much so that I'm concerned about freezing to death while running the snow plow this coming winter.

So last week they finally received the PowerFlip windshield and installed it on my machine. The windshield is great and operates quite well. But I haven't had a chance to give my machine a good long ride since the installation and honestly you all have me a little worried about what I might encounter when I get to stretch it's legs.

I'm wondering if the installation of a windshield creates a low pressure area in the cab causing extra heat from the front radiator to be drawn up the tunnel and through the shifter slot? Or are the coolant lines acting like a cooling system as extra air comes across them and gets pulled into the cab area?

I'm planning to go for a long ride over the weekend and I'm going to be quite disappointed if I start experiencing heat issues after 750 miles of happiness in my new rig. I sure hope that you can get your issue resolved and share it with everyone else looking for solutions. I'll keep you updated on my experiences this weekend.
