Can-Am Commander Problems

Having problems with your Can-Am Commander? We’re going to help you get them fixed. Usually, issues with these rigs aren’t too major and normally won’t end your ride. However, if left unchecked, they can balloon into costly repairs.

Overview of Can-Am Commander problems

We’re going to cover all the major systems of this UTV, from bumper to bumper. Here’s how we broke it down.

• Engine & Performance
• Transmission & Drivetrain
• Electrical & Wiring 
• Suspension & Steering

Engine & Performance issues

Can-Am generally does a good job of making solid motors; however any engine will experience issues if the cooling system starts to struggle.

Overheating is the main engine-related problem seen across the Commander lineup. This is normally caused by the radiator filling up with gunk. The same can also happen with the spark arrestor (effectively a baffle found in the exhaust). Some owners have even tried coolant additives as a last measure to help keep their Commander out of the red. 

Causes of Overheating

• Radiator
• Spark Arrestor

Radiator

Clogged radiators aren’t unique to the Commander, or Can-Am, however, they mounted it in a precarious location that makes it especially prone to getting clogged—it happens even faster if you ride muddy terrain. This is the number 1 cause of overheating, so it’s the first thing to check. 

A simple visual inspection can tell a lot. If you want to get a bit more precise, you can spray water from the garden hose straight at the radiator. Does it pass through or just bounce back? If it's the latter, you might need to do some cleaning. 

While it may be possible to clean the radiator in situ, the best bet is to remove it for cleaning. Soak it in a tub of water, occasionally agitating to break loose any stuck sediment. After a few days of soaking, try passing water through with a garden hose. Using a foaming radiator cleaner can speed up the process, although be sure to flush the radiator thoroughly before reinstalling.

Radiator relocation kits are available, and while effective, a lot of people don’t like how they look. If you’re riding some super muddy trails, you might want to consider this option.

Spark Arrestor

If you’re still running hot, the spark arrestor could be the culprit. To clean the spark arrestor, remove the bolts that retain the 90 degree exhaust tip. This will expose the arrestor. Slowly pry it out, taking care not to bend or distort it. Once out, the arrestor can be soaked in a mixture of water and rust converter to clean it out. 

It reinstalls the same way it comes out.

There can be other parts of the cooling system that fail, like the thermostat, but these are the most common on the Commander. Addressing these will normally solve overheating issues.

Transmission & Drivetrain Problems

The only issue with the transmission and drivetrain is excess NVH (noise, vibration, and harshness) seen on the late-model Commander MAX. It is normally described as a loud noise coming from under the floor pan at around 4600-4800 RPM.

This could be considered more of a trifle than a serious issue, as it doesn’t pose serious concerns to the vehicle but rather just the sanity of its occupants. 

There have been a number of fixes and revisions, but it seems Can-Am finally got it sorted out. Your Can-Am dealer can order a new ‘propeller shaft’ and install it for you—all the tin can sounds will disappear. 

If you want to DIY the fix, you can order the parts and install them yourself. Here are the part numbers from Can-Am’s recent service bulletin:

• 703501237
• 705211563
• 207582544

If you're in the market for a brand new Commander MAX, the good news is that all commanders from 2025 onward will come with these updated parts.

Electrical & Wiring Concerns

Late-model Commanders can have a range of electrical system problems. The two main problems are ‘no change’ conditions and complete loss of power.  

Charging System Problems

If your battery keeps going dead, you likely have a problem with your charging system. One of the easiest ways to confirm this is by using a multimeter; you should see 13.8+ volts while the machine is running and more like 12.5V while powered off. 

What causes charging system failure? We found that the 50A fusible line, stator, and voltage regulator can all be the problem.

While the 50A fuse can fail, it’s not very common.  If it does, the issue is that it’s difficult to get a replacement. Owners have resorted to wiring in their own aftermarket 50A to fix the problem. It can be found near the battery, under the rear driver's side rear floorboard. If you find this to be the issue, an aftermarket fuse (and fuse holder) can be installed with some basic electrical tools like a wire stripper and crimper.

The voltage regulator can be found by lifting the 2 plastic covers from the truck area above the exhaust. The regulator is found on the inner fender well on the passenger side. With it unplugged, you can run your Commander and check the connectors for adequate voltage using a multimeter. If the voltage is correct, the regulator should be replaced.

If you don’t find the correct voltage, you’re dealing with a bad stator. The stator isn’t too expensive, but replacement is not the easiest of jobs—expect a few hours minimum. 

While you have all the plastics off, it’s not a bad idea to replace your drive belt. 

Suspension & Steering Problems

Commander Limited models from 2012-2015 come equipped with FOX air shocks, also known as Air Control Suspension (ACS). This allows the rear suspension to be lifted and stiffened up.  

While air suspension might be right at home on a luxury vehicle, it isn’t so much on a UTV. The systems are finicky and often lead to all kinds of trouble. The extra parts associated with the system include a compressor, plumbing, a regulator, and electronics, all of which can potentially fail.  

A lot of Commander LTD owners opt to delete the air suspension. This can be done the easy and cheap way or the more expensive and involved way.  

The simple way is to plug the system with a ⅛ JIC fitting and remove the fuse for the air compressor. You’re likely to get an error code, but the suspension will remain in its neutral position.  

The more complete method involves swapping ACS shocks out for non-ACS shocks, then deleting all of the lines and compressor—everything associated with the system. To remove that pesky error message, you’ll need to have the ECU reflashed. This method is more expensive and involved, but your Commander will be completely free from air suspension woes.

Tips & Conclusion

Before you go out for a long outing, the main things to check are: 1) the radiator is free of debris 2) the battery is charging. Of course, while these may not be listed on the manufacturer's pre-ride checklist, make it a habit to check them nonetheless. These are the two things that will cut a ride short. 

Otherwise, there isn’t much to worry about. Sure, LTD models can have problems with air suspension, and 2022-2024 models have the infamous ‘tin can’ driveshaft, but at least these won’t lead to you breaking down.

FAQs

Q1: Are aftermarket driveshafts available that fix my rattling driveline? 

A1: Maybe, but there’s really no point considering Can-Am issued a recall to fix it. You can take it to a dealer or order the parts and install them yourself.

Q2: Are there any other Can-Am Commander recalls?

A2: Yes, starting in 2011, there have been 5 recalls: accumulation of debris around the exhaust (2011-2013), improper assembly of the steering column (2011, 2012), loss of steering due to stripped coupling on rack/pinion (2013), potential fuel hose damage (2023), and incorrect info regarding clutch pulley maintenance (2022, 2023).

Q3: Is it worth it to remove the ACS on a Can-Am?

A3: Some owners really enjoy the ACS. The best bet is to keep it as long as it’s in working order; when or if problems arise, it’s more economical to swap your suspension components for one without air suspension.
