Purchased a 2005 Toyota Sienna van. Van had some things I was aware of (poorly-repaired dent in right rear, sun-shredded paint, worn tires) but a number of items I wasn't aware of (leaky radiator, leaking differential, transmission cover clunk, and two leaky and rusted-on mufflers). We were assured at the time of purchase that the National Lifetime Powertrain Warranty would cover all parts of the drive train with the exception of things that need normal lubrication (oil change, etc). So even though we thought we'd probably be stuck paying for the radiator and the mufflers and the tires, we were confident that at least the differential would be covered. But alas - - NLPW didn't cover ANYTHING - - not worth the paper it's printed on.
The NLPW contract is vague and allows the NLPW supplier to slip out of any attempt at paying you any compensatory $$. Their game (which is common, according to the car manufacturer) is to not honor the warranty if they can remotely assert they don't have to. We've now had our car at the local dealer for three weeks awaiting ANY response from NLPW, despite our regular calls to them. They failed to honor the timelines they give to us in sending out their "agent" (labeled by a witness as a "bozo") to our local dealer.
In our case, (a) they told us when we first got the car that they'd cover the differential, but that we had to wait for three months with our faulty car before they'd cover anything; (b) they then asserted that we didn't properly do maintenance such as changing oil (which we had, and which we proved); (c) then they asserted that we hadn't properly maintained the "slip differential" in the 3 months we've had the car (but it turns out that our car doesn't even have a "slip differential", as verified by the car manufacturer); and (d) they then stated that that they don't cover the differential, since it's not listed on their vague contract. Our local contact said that he's used to such warranty companies trying to get out of paying, but this has surpassed even his experience.
I'd love to know when the differential became external to the powertrain !!
Auto Traders of Texas has not remedied this unfairness.
The repairs we're now faced with actually exceed the car's worth, so we'll probably have to dump this one and start over.
No more Auto Traders for me.
