My 2021 Chevy Suburban has an SD memory slot in the center console. There is no documentation for it. What is it for? Also, the owner's manual does talk about using USB devices for playing music through the radio. However, when I plug in USB devices (e.g. USB flash drive) with music, nothing happens. What am I doing wrong?
My 2021 Suburban is my fourth generation of Suburban so I'm very familiar with how they drive in general. The new 10-speed transmission was the best upgrade. I am loving it -- especially for towing up hills where it is no longer "hunting" for the right gear -- going back and forth between a gear that races the motor and a gear that lugs the motor. However, in some instances when letting off the gas, I noticed a decelerating effect that I had never experienced before. I wasn't sure if I liked this or if it was supposed to do this. I wondered if this would hurt gas mileage. But, after a couple of tanks of gas, I'm finding that I'm getting about a full mile-per-gallon better than my last Suburban. What convinced me that it is supposed to do this is when I tow downhill. It is clearly using the engine to brake. It works so well it almost seems too smart. Recently, I noticed that is able to measure the inclination of the vehicle (i.e. the angle of going uphill or downhill). You can display the up/down and left/right angles on the dash. Is it using this information to select the amount of engine braking? Seems like it is. And, to me, that is pretty darn smart.
I'm happy to report that the dealer agreed to compensate me for this damage.
I purchased a new 2021 cherry red tintcoat Suburban two weeks ago. Today, I was washing and waxing it for the first time. This required standing on a step ladder to access the roof. When I got to the spoiler over the back window, I discovered that it had been damaged and touched up! I can't be sure if this was done at the factory or at the dealer. I'm debating how to deal with this.
Thank you, bbeshoner! You helped me solve a years-old problem with my 2008 Chevy Suburban. It has had this rear left-turn signal problem since way back. I've had it in the shop four times at a cost well in excess of $1000. They replaced the BCM twice and the fuse box twice only to have the same problem reappear. When it failed most recently, I started looking for the problem you describe. I found that the problem centered around a wiring harness behind the under-hood fusebox (toward the driver compartment). When I pushed down on the harness, the turn signal stopped working. When I lifted up on the harness, the turn signal started working. I felt under the harness and detected a sharp metal corner poking into the harness. It is a difficult to access area. My solution was to wrap that area of the harness in leather and fasten it on with tie-wraps. Now, the metal corner cannot invade the harness. Now, my turn signal works all the time. I can press down or lift on the harness and it continues to work.
Last month truck had thick blue smoke out of the tailpipe on warm start. Twice in two days, and hasn't done it since. Oil level is fine. Thick puffs of smoke on startup is when my problems started. Get that Range device to keep your engine in 8-cylinder mode.
Just for hoots, I rechecked my oil today before I added any. It was only 1/4 quart low! Last night I checked it after driving home from work. I probably should have let it sit longer before I checked it. It seems the fix was better than I thought. 1/4 quart in 2070 miles is not too shabby. I'm going to keep tracking the oil usage. Then, after I have some confidence in what it uses, I will try removing the Range AFM disabler and see what happens.
My 2008 Suburban was consuming 2 quarts in 2000 miles. The dealer upgraded my rocker arm cover, installed the AFM oil deflector in the oil pan and cleaned out the carbon. Furthermore, I installed the Range AFM disabler. Just tonight I checked the oil for the first time (it's been too cold). After 2070 miles, the oil level was in the very middle of the hash marks (approximately 1/2 quart low). I'd say the fixes worked pretty darn well. I consider 2 quarts to 0.5 quarts a major improvement.
