2010 LT check engine light on
 

Hello All, I have a 2010 Tahoe LT, where the check engine light just came on along with the following warning: engine power reduced, stabilitrak, and traction control faults.
Prior to this, my TPMS light was/is flashing, just changed all four wheels, tried to set the new TPMS to the truck, but it didn't work. Once the check engine light came on the idle became very rough,thus producing the reduced power warning, for the pass couple days the truck seems to hesitate during start up, my question; have anyone experienced this issue before and what ultimately was the problem.:mad:

vexen1972 Welcome to the forum...

Might want to have the battery and charging system checked, also check the condition of the battery cables, particularly the ground cable....

you know what, it makes sense now, I had the factory radio replaced and a amp/with subs installed about a week ago..still taking truck to dealership this weekend

Please do follow up with what they find or don't find:cool:

Update:
Just returned from the dealership, the supposed problem was a bad throttle body, replaced( under warranty), light is out. As for the TPMS, for some reason the machine they have cannot read the aftermarket ones I have on the truck...so now I have to get 4 new sensors or remove the 4 that's in the original tires, but that's all the update I have, thanks given to those that gave advice

I have a 2010 Equinox with 60K miles. I've had regular maintenance every 3K miles. Just got stranded yesterday because I lost the ability to accelerate while on a one lane road. It then started knocking badly as I tried to pull in a church parking lot. Noticed a chemical smell inside the car. After restarting it a few times it drove a few more blocks but only 10mph. Started to call a tow truck but then it started again normally but light still on. Today same thing all over again so we'll attempt to get it to a repair shop on Monday. Is this a common problem with the 2010 equinox and is it the throttle? Why would this happen at only 60K miles? There are plenty of fluids and oil.

Problem fixed but GM should do more
 

After being without a car for two days the repair shop said my problem was the wires that are connected to the throttle were kinked and loose. They said that Chevrolet/ GM has a bulletin out regarding this but unfortunately not a recall. His opinion was that since he's seen this happen as well in the Equinox and also since my Equinox is only 2 years old there should be a recall. He said it could happen again and if it does my throttle will need to be replaced.

I'm tellin' ya it was very scary driving in the middle lane on a fast busy highway and slowing down so fast like that. Not enough power to keep it going if you are going uphill which could cause a serious accident.
