I have a '21 Laramie Sport 5.7 eTorque. I love everything abouty truck except for the eTorque. Sitting in drive thru lane at McDonald's or otherwise, I have almost his 3 vehicles when I eased up on the brake and that expensive alternator tried to shove me into the guy in front. I can GUARANTEE there is NO gas saving with mine either. I get about 18 mpg combined no matter what. I don't give a damn about mpg. Hate paying for it, but you buy a truck for the gas mileage, you're an idiot. You buy a truck because you need a truck and gas mileage is part of the price.
I forgot one other thing that ****** me off Auto Start/Stop. Besides the Expensive alternator trying to make me hit the guy in front of me, that BS about "seamless" starting is just that. Damned near broke my neck the 1st time I noticed it. I wish it could be PERMANENTLY disabled. Temp fix cost me $100 for a cable, but it works.
Outside of that, I love my truck. Put 50K miles on it in one year. Maybe one more year then get a new one. Maybe by then they'll have that expensive alternator fixed.
