I think it does come down to if someone is running with or without the w58 bandaid. At least where I travel traffic can be a real pain in the @$$, especially in the dense metro areas i've seen people block disabled autos from getting to the side of the road but then these are probably the same sorts that won't move for emergency responders, but you know how that goes. It's a shame you can't drive your 2015 without some doubt, i'm in the same boat on my 2015. I made a couple trips up to DFW and between heavy traffic, construction I couldn't help but think to myself the whole time if she goes down let it happen out of town.I'm not too concerned for my safety. A tone wheel failure isn't much different than getting a flat tire. When it happens, you have to get to the side of the road as soon as you can.
The problem with tone wheel failures is the truck defaulting to limp mode, which isn't fun if the failure happens in a rural area and/or while towing. Since I'm currently under the AEM warranty, I've been selfishly avoiding taking action on a preventative repair. Since last November, I've intentionally been driving the 2020 EcoDiesel on longer trips. But I can't do that forever. I keep thinking the tone wheel will fail on my 2015 when commuting to work or running errands around town, but it hasn't. And it may not fail while I'm under the AEM warranty. I still have two more years left of the AEM warranty.
