2019 Vibration in steering wheel.

Hi all, I just recently purchased a brand new 2019 Nox with the 2.0 engine. When I am driving between 30 and 45 mph with the rpm's around 1200-1400 I am experiencing a vibration that can be felt in the steering wheel and the door, it can also be herd as a rumbling. It happens more often when I am going up a hill. The best way to describe it is when you drive a manual transmission and you are in too low of a gear for the speed in which you are going.

I took it in to the dealership and was told they could not notice anything. I personally find it takes away a lot of the fun in driving the vehicle and is a huge distraction to me.

Is anyone else experiencing this?

Was the vibration present when you test drove the vehicle, prior to purchase??

I did not notice any vibration at time of test drive.

Have you tried forcing a downshift to a lower gear--to see if it is caused by lugging the engine? That situation happens in 9th gear at approx 60 mph. Caused by the programming of the transmission to get it onto highest gear possible to increase mpg. Haven't previously heard of it at 40-45, but can see where that would be the case at a constant speed. Try forcing the downshift and let us know.

That is when the active noise cancellation kicks in through the door speakers. Still I have the same model and no vibration just a bit more exhaust noise.

I believe it would be from lugging the engine. I have not tried it in manual mode. I have never experienced this in drive mode with an automatic vehicle until now.

You really have to feather the throttle going up hill to experience the vibration, any bit more and the transmission up shifts to help the vehicle maintain speed. I have experienced it as well when driving through neighborhoods feathering the throttle maintaining 25mph. Rpm's are around 1200 and 1300 when it happens.

Yeah, I believe you're experiencing the same thing as I have, just in a lower gear and at lower speeds than I have at 60 mph and 9th gear. RPM corresponds as well--right around 1400 rpm. I just kick the throttle enough to force it to downshift; the rpm then jumps to approximately 1900-2000 rpm. It's a function of the transmission programming to get the vehicle into the highest gear to maximize fuel mileage; driven by EPA and CAFE (Corporate Average Fuel Economy) standards.

I tried what you said in Manual mode, at around 45 mph in 9th gear I could feel vibration, I downshifted to 8th with no change in vibration or rpm's. Finally when I shifted down to 7th the rpm's rose and the vibration went away.

I am wondering if all the 2.0 Equinoxes are experiencing this. The rpm's just seem geared too low for the size of the engine. I wish there was a way GM could adjust it through the computer.

GM can adjust it, but they have chosen to program transmission upshift points to maximize fuel economy--at the expense of "lugging" the engine. As I stated above, I apply enough throttle to get the transmission to down shift and raise the rpm to what I consider the appropriate level. The other alternative is to shift to L and set the upper range limit to 7, which is a 1:1 ratio and it will eliminate the "lugging" at 45 mph.

Noticed this in my 2.0 Diesel. I came to the forum to see if anyone else has experienced it. It has happened 3 times, so far. Will have to see if I can manually downshift since I cannot control the hill speeds (traffic).
