parking assist sonar and rain
I searched, but no luck. I have a two week old 2012 Tundra Crewmax with the parking assist sonar. A few days ago we received rain. My rear sonar's went off continuously when in reverse, even though nothing was behind me. I cleaned and dried the rear sonar sensors, but the issue continued. Once the truck (and streets) dried up, no more issue. The manual indicates this could be a problem if water, mud, or other debris gets on the sensors, but after cleaning them off it should have operated correctly. My concern is if this is possibly water getting in and shorting out something, or if it is just an idiosyncrasy of the system. Dealer was no help. I explained it in detail and even suggested wetting the rear bumper, but they simply turned it on and noted that it was now working correctly.
I can understand the heavy rain and spash-up creating a problem, but when the rain stopped and the sensors were cleaned and dried, the problem should have stopped. It didn't. It continued until the entire bumper had dried. (Next day)
So, does anyone know if this is a common issue I should ignore, or is there something wrong that needs to be fixed? Any help will be appreciated.
