I have a 2021 Tremor with just over 35k miles. Went out and tried to start the truck and it began to sputter, shake, and ultimately shut off. I tried to crank it a second time with the same result…it would idle for a few seconds but sound rough, then all the lights came on the dash and the rpms bounced around a good bit…then it died (again). I had it towed to the dealership and now I’m waiting on the diagnostics to be run. It’s still under warranty (thank God) but was curious if anyone had thoughts on what this could possibly be OR if any known issues like this have been common for this year model?
Some type of sensor.
Crank position probably.
Throttle body?
So what was the problem? Mine is doing the exact same thing. Waiting for a tow truck now.
Wow. Sorry to hear, on both of these. How many miles does yours have, out of curiosity?
Just interesting to hear both issues are at 35k.
