My Air Bags are leaking down overnight. Is that normal?

Some loss of air from the front and rear air storage tanks is considered normal.

  • A drop in pressure of 10 PSI an hour or more should be addressed by an authorized service shop.
  • A leak of less than 10 PSI an hour will often be difficult to locate and should cause no operational issues with the vehicle.
  • Air leaking from the suspension air bags usually presents itself by the coach leaning after it has been sitting for a period of time. If the coach is leaning after sitting for just one night a service tech should be able to locate and correct that leak.
