Need help troubleshooting-2011 Chevy Silverado

It does make clunking sounds on occasion

Have had the issue twice on my 2012. Brought to a shop and had them read the error codes. Both times was the rear wheel speed sensor. First the right then the left about a year later. They are about 80.00 at AutoZone and simple to change.

That’s what I was thinking. The ABS light doesn’t come on.

GM went to shite after the bailout.

Those 09-13 Silverado and Tahoes are the shitties vehicles GM ever made.

They completely ruined the brand to me and my family, used to be Chevy for everyone and now it's all Toyota.

Didn't help they moved the GM plant away from shreveport to over seas, took a massive government bailout and then made shitty vehicles.

Best thing I ever did was get rid of my '11 shite box Chevy

The few years after the great recession were not good years for cars especially GM. You had parts manu's going bankrupt left and right or getting swallowed up by conglomerates. Things got better around '13 but imo, we still see negative effects from the GR.

I had the same problem with my 2008 GMC. it would shift real hard. had the same traction control light.it drove me nuts.it was bad plugs or wires. changed them and was like new. drove the truck for at least 2 years like that. i never wouldve believed it. worked for me. still doesnt make sense to me but it worked. one plug was real bad

I had the same issue on my 2011. Mine ended up being a misfire on number one cylinder. Which would kick a code for stabilitrak and traction control.

You must begin with having the computer(s) - anti-lock and powertrain -checked and get the code(s) and see which code(s) correspond with the indicators on your instrument panel.

Also check to make sure your brake fluid is within the proper reservoir levels. Mine got low and caused these alarms to come in.
