Weird Noise on new HD 10 XT-P

Thanks for the information. I’m out of warranty. Is changing the vent tube a difficult task?

The pressure relief valve should be located right on top of the fuel tank cap (that contains the fuel pump sender and other hoses) and is the round valve that is located after the "Y". It is directional and should have a flow arrow on it so pay attention when you remove the old one. It should be as simple as pulling off the two pieces of hose and reinstalling, good luck with the replacement.

Love my XT-P so far but have a couple of issues that I wondering if anyone else has had. When ease off the throttle I have a loud annoying vibration rattle at around 13-15 mph. Sounds like metal to metal rattle and I have check all heat Shields on the engine and don't find any loose one. Sounds like it coming from the right side.

Also, when I come to a stop I hear a whistle sound coming from engine area but then the coolant fan will kick on and it stops. Temp showing 199-201 and no high temp indicator showing on dash. Not sure if the Defender has an audible high temp alarm and this sounds more like a hot radiator whistling sound than an electronic alarm sound.

Only have 13 mIles on it and will be taking to my dealer after we are released from this self quarantine but thought maybe someone has had similar issues.

Did you ever find out what was causing g the rattling? I have a 2020 lonestar and it's doing the exact same thing. Nothing is lose in the fro t suspension but definitely gets a harmonic rattle around 13 mph. Thanks for any input.

I get the fuel tank vent line noise From time to time when it’s real hot out and I’m having fun playing hard. That’s about the only time I’ve herd it. Good test is if you can make it do it and open the fuel cap at the same time. I bet it will stop.

I was thinking the noise meant it was releasing press like it should.

No sir the dealer had it 2 weeks and couldn't find out what's causing it. They opened up a discussion with Can Am in case something happens after warranty.

Seemingly I was having the same type of noise / rattle / clanking noise, on my 2019 Defender HD10 XT. After numerous calls to different dealerships, one finally provided a solution. I was advised, by a Can-Am dealer, to go to a Ford dealership and get a 4oz bottle of “friction modifier” and dump it into the front differential. After 50-100 miles, haven’t heard it since.

I have the exact same issue on my 2020 Defender Max Lonestar. That friction modifier fix sounds interesting. Let us know if you hear anything from the dealer!

I just bought a new HD10 XT yesterday and mine does the same. I have to go back to the dealer Tuesday to finish some paperwork and will ask them if they know anything. It’s kind of annoying, especially on a new rig.

I've got a vibration- rattle coming out the frt on mine @ 12-15 mph. It's seems to be coming from the left side...I kinda think it maybe related the frt diff or driveshaft? I've only got about 20 hours on it...been doing it from the time I got it home. I plan to talk to my dealer today.

Please let us know what they say. I just bought mine Saturday and have not been able to ask them about it yet since they are closed on Mondays.

I'm assuming you have the same noise? Come to find out my dealer is closed on Mondays also..I'm in IL, dealer is across the river in Iowa...

Yes, same. I am in Southeast Missouri. Got to go there tomorrow for some paperwork, so will press them since I have only about 20 miles on mine.

GB20 · Aug 25, 2020

It maybe a few days on mine, I haven't discussed this issue with the dealer yet. I do have a few other issues also. He had said he would pick it up & drop it back off to me 2.5 hours each way.... With that said no clue when he can pick it up yet? Please keep us posted, I will also...Thanks!

My dealer says his personal Defender also does it and he knows some others that do it too, but not all. He said it’s some type of harmonic in the roll bar down to the frame. We are gonna try a couple of things when I take it in for some accessories to be added. Will advise.

Sorry I haven't been active on this post but my wife's health got so bad I sold my 2020 XT-P she went down hill a LOT faster than I expected and lost her on July 12th. I'm wanting to buy another Defendef now maybe the XMR version but hesitant because of this noise problem. I can guarantee on mine it was not a harmonic issue. MI e had to be at normal operating temp before it would start and would take a mile or two. It was something to do with the differenials I believe and the oil had to get warm/hot before it would start.

Sorry for your loss, hope things get better for you.
