I was recently on Steens Mt. and had a diesel exhaust fluid system failure warning on my 2014 6.7L Ford. It said I would be limited to 50 MPH in 50 miles. So after 50 miles of nagging warnings, I assume it did limit my speed, but I wasn’t in a place to try to go faster. At about 52 miles, I pulled over to speak with Mother Nature, truck idling. When I got back in the truck, the fault cleared, no limitation on speed.
Yesterday, I took the truck in for routine service, and had them check for fault codes. No codes present. They asked what DEF I used (Peak Blue DEF), and told me that 60+ percent of issues they saw were diesels that used Peak. There are a number of factors that could be involved, ranging from sales percentage, to storage and shelf life issues. All that said, I’m going to switch to MotorCraft from the dealer, as it is roughly the same price as Peak, or if in bulk, less expensive. Just drive by and top off the DEF tank.
Apparently, the DEF failure Issue isn’t just a Ford issue. A friend with a 2016 Dodge has had similar experiences. I suspect GM is affected, too.
Has anyone on WTW experienced DEF problems with their diesels?
