    Should I disable AFM on my 2017?

    2017 Suburban, 80k miles. Seems that the AFM/cylinder deactivation system on these engines might cause problems down the road based on what I've read. What's the consensus here - Is it worth disabling? If so, can I get away with one of those OBD dongles and just leave it in the port? Sent...

    2017 Suburban..Bad door switch preventing interior lights from going on when door is ajar?

    2017 Suburban Premier.... The passenger door, when opened, does not trigger the interior lights. The Chevy dealership wanted $275 to swap the sensor switch, which is inside the door. Naturally, I'd like to attempt this job myself, though I'm curious if anyone else has dealt with this...

    17 Suburban Premier - rough idle when warmed up

    Just purchased a used 2017 Suburban Premier about 2 months ago. I notice that after the car has run for a while and is warmed up, coming to a stop and staying in drive there is a fairly noticeable rough idle. The whole truck gets shaky. The roughness goes away upon shifting to neutral or...

    Just purchased used 2017 Suburban Premier, anything I should look out for?

    Hey everyone, I had a 2015 Tahoe LTZ which I just traded in for a 2017 Suburban Premier. I had bad luck with the Tahoe - I'm convinced that the 2015 had a bunch of first year kinks they had to work out. I needed more space, plus the Tahoe always left a bad taste in my mouth due to the massive...

    Steering wheel lights AND center Infotainment screen stopped working at same time

    Well this is new. I went to drive the car last night...the steering wheel lights were not lit and the center screen, while technically back-lit, was not showing anything. Heated steering wheel button still did something, as did the arrows that change the screen on the dash, but I could not get...

    Chime volume is LOUD (and it's turned all the way down in settings) - '15 Tahoe LTZ

    2015 Tahoe LTZ The chime sound seems quite loud, and I swear sometimes I hear it get louder as it does its ignition turn on sequence. In the settings, the volume is turned all the way down. Anyone else notice this on theirs?

    False alert rear parking assist - '15 Tahoe

    2015 Tahoe LTZ. Went through car wash today...and now when shifting into reverse the seat vibrates and red exclamation point appears on screen, as if something is RIGHT there behind me, even though it's completely clear. I've had this happen before when the sensors are covered with snow or...

    Need opinion on what to do about broken headlight

    I have a 2015 Tahoe LTZ. The driver's side headlight is full of condensation, and now the daytime running LED no longer works. I had considered drying out the assembly and sealing the fixture to try to fix myself before the LED strip stopped working, but now that that's out, I'm more leaning...

    How hard is it to remove headlight fixture on 2015 Tahoe LTZ? Moisture in headlight.

    Yesterday I noticed some moisture inside the left headlight. Was considering attempting to fix myself by removing the headlight fixture and caulking where the moisture is getting in (saw some DIY youtube videos). However, I'm not willing to attempt this if removing the headlight fixture is a big...

    Roof rattle sounds at high speeds - 2015 Tahoe LTZ

    I recently picked up a used 2015 Tahoe LTZ with 67k miles. The car itself is in excellent condition and drives great. However, when I get on the highway at speeds of 65 or 70 and above, there is a rattle sound that comes from somewhere above me (very hard to pinpoint). There are no crossbars up...
