They do have a throttle body problem and they're replacing them under warranty. My understanding is when this happens turning it off and back on clears it at least temporarily. This is the first one I've heard that wouldn't restart on its own. This might be a different failure.
Not to mention the mfr will make different versions of the exact same tire for different OEMs, sometimes labeled identically. I think there are at least 3 different OEM versions of the Michelin HX MXM4 - one for Honda, one for Ford, etc. etc.
I've heard good things about Cooper tires. If you want a good comparison from actual owners - go to tirerack.com and look at the user surveys for CUV/SUV tires.
So it's only inconvenient once a week or month at the carwash where all you have to do is throw the key into the cupholder, compared to the 2, 4 or more times you have to get in and out of the car every day.
Only if you leave it on there for weeks or months. Use the vinegar, wash it off when you're done and it's fine. If you can drink it then it usually won't hurt clearcoat.
The dealership is 100% correct. If you check the factory warranty info (if it's not in the OM go to motorcraftservice.com) you'll see that the tire mfrs warranty the OEM tires, not Ford. This is clearly a tire defect and should be covered by Pirelli. Just go to a local tire shop and let them deal with Pirelli. If they agree then the tireshop will issue the adjustment towards a new set. If you don't want new Pirellis maybe the tire shop will swap them for you. But this is definitely not a Ford issue.
On a related note, I just got new Latitude Tour HP Michelins (18") on the 08 Edge. They lasted 34K miles but the treadwear warranty is 55K so I got a pro-rated adjustment of $330 towards a new set.
I LOVE that feature and upgraded to a Titanium Fusion to get it. The fact that I can open the door, start the vehicle, stop the vehicle and lock the vehicle without taking anything out of my pocket is great. I have both the IA key and the IKT (integrated key with remote buttons) for different vehicles. There isn't much difference in size. Over time they'll get smaller.
It will ride a bit harder. It will only affect the warranty if you have a failure that's related to the springs - those parts may not be covered but the warranty isn't affected for the rest of the car.
A current Limited has a base MSRP of $35,100 and with $2500 in current incentives has a X plan price of just below $31K so that would be the comparison point.
$25K is only about a $6K discount which isn't terrible with only 10K miles but personally I'd be looking for a bit more to make it worthwhile taking the chance on a used vehicle.
The good news is you still have a lot of factory warranty left.
I would check the current price on a similarly equipped new 2013 model for comparison. For me it would have to be at least $10K cheaper to make it worthwhile.
I would also question why a vehicle that new with only 10K miles was sold or traded in by the previous owner.
