Vibration in the steering indicating maybe tires were not balanced properly. Took it to the dealer, and was given another 2020 to drive while mine was in the shop. Rental ran smooth and no vibration at highway speed. Got my car back and they balanced the tires and did some other thing and Most of the vibration is still there. As expected, no vibration at lower speeds, but, when moving at 25mph and I accellerate fast, and a light touch on the steering, the car pull drastically to the right. I know many front wheel drive cars have a tendency to do this but I think mine is excessive. I have the LT2 with a v-6. I will take it back to the dealer next week. Anyone else experience this?

I can't say I've noticed any vibration, but my 2019 RS definitely torque steers more than any other car I've owned. I could imagine a situation where an LT model with lighter wheels and probably less aggressive tires could suffer even more from it.

Doesn't bother me personally. Even with a relatively lively engine applying its torque to the front wheels and the leverage advantage of 9 gears, I figure GM could have engineered it out. But I am content with where they spent the money to develop this car.

UPDATE: Took the car back to the dealers after they "ballanced" the tires, still vibrating. Dealer said they test drove and did notice the vibration. Picking up the car today, 11/4/2020. We shall see.....

UPDATE. Since my last posting 2 different dealerships tried to fix the vibration and then said its just me. Lawyer tried the lemon law, but GM refused to even consider it. Vibration is still there. I guess I will have to wait until something gives out or breaks. Lets hope it does not kill me.

I have a vibration and low hum noise when I go over 65. I usually start to hear around 72 and have to drop below 65 for it to stop. Almost sounds like wind vibrating something in the grill. I haven't taken it to the dealer yet. I have right at 1500 miles on it :(

I read that chevy is recomending putting a semi hard rubber piece in the front grill.

I brought my vehicle in and initially they said they couldn't hear it. I made them go again and I rode with them. I pointed out what I was hearing and they too could hear it. I just got my vehicle back and this is exactly what they were instructed to do. I haven't really tested it at the speeds it was occurring, but should tomorrow. Will let you know how that goes.

Blazer has active air shutters that block off grill at higher speeds. Is the noise specific to a certain speed that you drive. Perhaps you can tape off parts of grill to see if that influences noise.

I have a 2021 LT2 AWD V6 and at about 1500’mile I noticed a vibration I feel it thru the steering wheel and the floor pan , I’m hoping it just a tire issue. Gonna have it look at tho
