I have a 2006 Odyssey and recently we’ve had issues with the Serpentine belt slipping when it’s raining hard. The battery light comes on and steering tightens then as soon as we straighten it all goes back to normal. The under shield has been missing for several years and this issue has just started so I can’t imagine that’s it. The engine cover has recently been lost but from what I’ve read that’s not causing this issue. Any assistance and advise is greatly appreciated.
