    2021 Tahoe engine noise - knocking sound

    One last thought..would liked to hear you say the date and time of day. Also include showing vehicle and vin # on same video to eliminate any possible arguments. AFM failure I suspect. Use your warranty! You paid for it.

    Does anyone have any experiencing ordering accessories through the Chevy store online? OR should you buy it through your dealer?

    To answer your original question. DEALER or On line..Get the GM part # and search online. Many GM wholesale sites. Save money almost always! The dealer has to buy and mark up to pay people to work there. Sometimes your selling dealer will sell you at cost. SHOP!

    Stupid question: what exactly does Tow/Haul mode do on 2013 Escalade ESV?

    Light trailer towing isnt a problem for you at all..tow haul ups the line pressures in your tranny and extends the shift points...if your towing in hills that's causing alot of up shifting you need to use it..tranny will overheat. Single axle light trailer no problem at all.
