I know of an owner of a Lexus whose wheels have been thru at least a handful (or more) of tire changes (due to frequent nails requiring removal and patching). One sensor was cracked during that repair process at a tire center, but continues to work fine. The car does not report actual pressures for each tire, only when a sudden or large drop in pressure occurs in any one tire, at which point it pops up an alert, without identifying the bad tire.mynameisjim wrote:I think the sensors cost around $20 and are supposed to be replaced every time the tire comes off of the rim
