Thanks. I already had both motor mounts replaced. GM should do better. Although this truck is predominately city driving, you would think motor mounts wouldn't fail at 54k miles and a mere 3100 hours on the engine.

What is the best way to confirm broken motor mount? I don't have unusual vibration at freeway speeds, except for the ones induced by terrible California freeways. But what I do notice is occasional disruption felt in the steering wheel during left hand turns, like it is fighting gravity or something. Not fast turns, just standard speed. I know this is all a bit vague, but I just had a coolant leak repaired and the mechanic said I had a broken motor mount... Which seems weird at 54k miles. Any help appreciated. Thanks.

Hopefully it solves your problem long term. My 2017 ended up as a GM buyback due to problems that could not be resolved by dealer. Problem started at less than 500 miles though.

I have a 2018. It seems like it is intentional flaring but very slight. Don't know the purpose though, but my guess is more efficient drainage. Do you have a picture of what it looks like on your truck? Here is a bottom up view of mine.

I know this is an old thread but wanted to share my experience (2018 Silverado LTZ) or those who might have this problem... and go searching for the solution. Last night I pulled into the gas station in a tight left wheel radius and turned off the truck and fueled up. Got back into the truck (using handle on pillar, not steering wheel) and went to start it up. Inserted ignition key and it wouldn't turn. My previous experience is, gently move steering wheel while trying to turn key... but when I did this I couldn't move it to the right..... so while "jiggling" it the wheel inadvertently locked up to the left. Now there is no "play" in the steering wheel. Frustrating! So there I sat with my hazard lights on because my otherwise perfectly normally operating truck is now stuck. Tried remote start, vehicle started fine but steering did not unlock. Felt helpless. So I got a snack and came back to the truck. Never underestimate the power of a good snack lol. Then I tried something unscientific... I put the key in ignition gently with my left hand, (instead of right), thinking that a imperceptible adjustment in key position *might* make a difference. And it did, although probably just a coincidence. I can't really pinpoint what happened to fix the problem, although I do know that the steering wheel wouldn't move at all prior to inserting ignition key, so I didn't bother with that. The steering magically unlocked and I was able to start up and get the hell out. My first experience with this characteristic of "normal" operation. For the future I guess I'm going to make it easier on myself and slightly turn the wheel in opposite direction of radius before I turn off the truck. If this doesn't help anyone I hope you at least got a good laugh out of it!

Following. This started happening on my 2018 Silverado 1500 about six months ago. You would think that for the money we pay for these trucks that you would get at least four years use before everything starts dying.
