I have a Nissan that I purchased from another dealership. I also purchased an extended warranty that is required to be executed by that dealership. I brought my vehicle in because the TPS light would not go out. The sales dealership told me they would have to send it to the Nissan dealer because the TPS is proprietary (or rather, the reset tool is). It was determined that three of the sensors had dead batteries. They were replaced, covered by the warranty. About a week later, the problem recurred, and the process was repeated. The 4th sensor had a dead battery (why would they not replace all four in the first place?). It was covered by the warranty, but I had to pay the deductible again ($100 each time). Sucks, but that's the rule. I paid it and the service counter person at Nissan said, "I don't know why they didn't just do all four at the same time." Fast forward about 7 months, the TPS light comes on. I adjust the pressure in all four tires, but the light doesn't go out. The next night, I do it again, but the light doesn't go out. I bring it to the sales dealership, they bring it to Port City Nissan. Port City Nissan resets the 4 TPS units, tries to bill the sales dealership one hour for the labor. When they balk, it's lowered to $54.16. The warranty won't cover this because the parts are under warranty and should be covered by Nissan. The sales dealership passes the charge on to me. I call Nissan, and at first I'm told, "We didn't charge you, we charged them." When I press, I'm told, we billed them because you brought it to them, you didn't bring it here. (This sounds like I would have been covered if I'd brought it in directly, to me.) I ask why anyone is being charged if the parts carry a 1-year warranty. I'm told that that's only if the parts are defective. I ask how they are not defective if the TPS light does not go out when tire pressure is reset. "I don't know." I then ask, does this mean that the next time the equipment doesn't work right, but is not defective, if I'm going to have to pay $54 again. No good answer. Right now, I'm out $54 because Port City Nissan wanted to feed off the teet of the warranty for the "service" of resetting the TPS sensors (incidentally, Tire Warehouse has done this on my other Nissan free of charge when I purchased tires). So, five phone calls later, the only thing I know is that if it happens next week, it's covered. Beyond that, it seems they won't guarantee not to pork me when their "warranted" parts malfunction. Avoid this place like the plague that it is.
