Three Most Common Problems and their Solutions

Lucky for you, Honda CRV Shutter Grille doesn’t have that many problems. But here are the most common ones.

#1: Shutter Grille Warning Light – Heat Issues

Whenever you find yourself in extreme heat in summer, what’s the first thing you do? You probably turn on the AC. Even though it’s almost natural to any user, this is not ideal.

During summertime, and if the car was parked under the sun, you might get this issue. When turning on the car and starting the AC, there’s a high chance to encounter the problem.

The shutter grille warning lights will go off, together with a “power reduced” sign.

This means that the radiator coolant temperature is too high. This is not an ideal situation as the engine is not cooling down. And by having the AC on, there’s more pressure on the engine.


Try to find a place in the shadow or under a roof to cool down the car. Park it there and turn it off. Let it cool down completely before using it again.

If the lights are still on after the car has cooled down, then you will have to contact your dealer.

#2: Shutter Grille Warning Lights – Snow Issues

We’ve all been there. Extreme weather driving is never safe, but sometimes we have no other choice.

So, when it comes to driving in the snow, you will also have to keep in mind that the shutter grille might get obstructed.

If the warning lights go off during a snowstorm, it means snow has blocked the shutter grille. By doing so, your engine will lose power and can get overheated, even in winter!


Please always be careful when maneuvering during snowstorms

Here is why you should not stop driving:

First of all, the visibility is low. Meaning other drivers will have difficulty noticing you. Keep driving until you reach the area off the road. Don’t move your foot from the gas pedal.

When you find a clear area to park then you will be able to stop and fix the issue. You will need a bottle of water. But, even better, few bottles of water.

Always have at least one bottle stored in your car.

  1. Pour the water on the grilles to remove any excess snow.
  2. Now, put your thumb over the hole of the bottle.
  3. Squeeze the bottle with your other hand and spray it all over the grilles. Spraying the grilles should remove all the snow and turn off the warning light.
  4. Take it to the car dealer’s to check the problem further.

#3: Shutter Grille Physical Damage

From time to time, small accidents can happen that physically damage the shutter grille. If this happens, it might not work as intended anymore.

When grilles are physically damaged, they can’t do their job. You will see the “power reduced” sign as well, and if not, that just means that the contact was not damaged.

Apart from that, it will not perform the initial open/close on the engine start test as all the shutters are supposed to do.


First thing, you have to order a new grille and a new shutter assembly. 

  1. Take the facia cover off. 
  2. Unsnap the broken grille and snap a new one.
  3. Unbolt the shutter assembly from the radiator support and remove phillips screws. 
  4. Check all the articulating parts. 
  5. Apply reversed pressure to the curved shutter pieces.
  6. Reassemble the whole assembly.
  7. Unsnap the wiring harnesses the shutter assembly has running down its length. 
  8. Test the cord while laying down in front of the vehicle. 
  9. Plug the wire back into the vehicle harness.
  10. Close the hood.
  11. Press the remote fob to lock the doors.
  12. Press the remote start button and start the vehicle.


Every car has its problems, and you will never find a vehicle with zero issues. However, the Honda CR-V is a fantastic car all in all.

Shutter grille systems are now available in many models. So, if anything happens to it, you will easily find a mechanic to help you solve it. This technology is well known by now.

Learn how to behave in case any of these issues occur, and you will know how to act each time.

  1. You forgot a 4th reason. Literally over a thousand bugs stuck on it. Wash off and it works. Not everyone lives on the coast. Jams up al the time in Missouri.

  2. Help…2018 Honda CRV ex with shutter grille alert problem.   A flying truck retread hit the front of my car so the shutter grill was replaced. My Honda dealer doesn’t know what to do with it.  they did diagnostics and came up with nothing..  Here is what I know:  it’s happened twice when I was driving, 70-75.  I get a shutter, speed alert, and my car slows down  with the alert. It doesn’t seem to overheat.  At that time I was getting 31 miles per gallon and after that happened I was getting 19 and it slowly built up to 31 again. The gas mileage wasn’t reduced after the alert this time. Turning off the engine seems to reset it.  it doesn’t happen with local driving or slower speeds. My Honda dealer acts like they don’t know anything about it and can’t figure it out but it seems to be a noted problem with 2017 and 2018 CRV’s per the Internet. Does anyone know who/how to fix this problem?  Any direction that I could take, would be helpful… Thanks in advance.

  3. is it safe to drive the car when it says “Shutter grille problem. Power reduced”. The warning came on this morning at 5:30 AM when it was 72 degrees outside. I was driving from Washington DC to Philadelphia but I don’t think it was a problem of weather extremes – it might have been the bug problem on the grille. I need to know if I should get it fixed in PA or if I can drive back to DC and take it to the dealer.
