    Hi everyone,

    New to this forum, but definitely not new to Toyota tundras. Recently picked up a 2016 CM. Prior i had a 2014 and a 2012 DC, all with the 5.7. So i feel fairly confident when i say, i know what these engines sound like when the start.

    Which brings me to my concern. My 2016 has maybe 2500 miles on it, and probably since 700 miles in, on a cold start (first thing in the morning) it seems very weak when it starts- like it sputters to start. Almost as if its misfiring? But it never throws a code and it does always start, idle, and drive fine. Its only on cold start. After its warmed up no issue, normal start.

    Any thoughts? Any one else experience this? Does this warrant a trip to the dealer?

    Any thoughts would be appreciated.

    My suggestion is to use your cellphone and film your condition during these cold starts. If what you say is happening only during cold starts the dealer might not be able to replicate your conditions without letting your truck sit around to cool off. (I hate when the shops say they can't replicate the issue). I don't know if there's a simple battery test they can perform to check for a bad cell, but hopefully that's all it is.

    Any auto parts store has a battery checker to check for bad cells. They do it for free.

    Sometimes when I start mine it will start, then go to a low RPM for a two or three seconds and then the RPM's will jump back up. Never thought to look at the RPMs while it's doing it but it only does it about 1 out of 20 starts. Doesn't sound like what you are experiencing. Been meaning to ask on here if anyone else's does it? Maybe @LOTSOFTOYS knows?

    Haven't really heard of this concern. Might need the battery tested... if your worried about the dealer not duplicating it, drop the truck off. Leave it over night and show up in the morning. Start it up in front of the tech and see if it does it. That takes all your mystery out of it. Can't tell u how many times customers start their own car in front of us, and it doesn't do a damn thing. They get so pissed, but atleast it's not at me. They are frustrated with their car... but they believe us then that we could not duplicate it.

    Just to give you the other angle at the equation
