2006 Buick La Crosse 6 cyl Front Wheel Drive Automatic 48000 miles
When I go uphill/downhill or turn a sharp corner, I can hear water sloshing around in the dash - I think in the region behind the radio/heater/ac controls. Buick had our local dealer install a restrictor to the heater core, but that did nothing to stop the sound. Others can hear this noise, so it is not just me. The dealer had replaced my radio earlier this year; the sound started after that, but I can't remember if it was immediately after.
The dealer's bodyshop also checked every possible entry point for water but said they could not find any place where water could have enter from the exterior of the car.
