Many people have if you read some of the posts, but cummings dont give a crap.
A simple reprograms, so warning stays on but does not make the vehicle only do 5 mph as they have for a fire truck, EMC vehicles.

Does anyone have any insight into the current DEF sensor shortage at Navistar?

My 2019 International LT with Cummins X15 has been running great, but DEF sensor in tank (often called QLS sensor) failed and engine was derated to five miles per hour. The sensor sends tank level to computer. My faulty sensor said I had empty tank when, in fact, it was 3/4 full.

The truck has been down two weeks. The part was ordered two weeks ago. Dealer says I'm on critical backorder, but no eta for when new sensor will arrive. Typically its a quick fix and under warranty, but no one has the part. Navistar has not helped in anyway, I can't get past the dealership and talk to anyone.

I've heard there are many International products shut down for the same issue. The service shop I'm at has 15 trucks waiting for the same part. The dealership I bought my truck at said they had 55 trucks on critical backorder. The guy who runs the company I'm leased onto says he's got 25 down and they've been down for the last 6 weeks.

When will they be available?
Where are they made?
Who makes them?
What is the reason for the supply issues, besides pandemic?
Why are so many failing?
How do I get past the Navistar dealer firewall?
Is there a way to bypass sensor?
Anyone interested in a class action lawsuit?

We're in South Texas and we've replaced these every year as well. That time of year is here again, the local dealer has 52 on back order and there are none at any other in Texas. We've had to replace them all over the country and have driven to Louisiana and Oklahoma to deliver them. These trucks have been an absolute nightmare because of this very sensor. We've also had DEF contaminate/corrode the fuse block some ####### mounted to the side of the DEF tank, and had the heater valves go out as well. I would LOVE to join a class action lawsuit! Please email me at frank3@fmtransportation.com if this goes forward.
