2011 Chevy Tahoe Electrical issues

strappy

I have a 2011 chevy Tahoe , the brake light comes on the abs light come on the traction symbol comes on the traction control service comes across my screen. The speedometer goes nut bouncing from 0 to 60 to 50 all over the place can't eve tell how fast I'm going. I lose power. When I push the pedal nothing! I'm stuck going 20 to 30 miles and barely make it up a hill having absolutely not power. Very dangerous. Sometime the locks will unlock and lock but rarely. It will also shift very hard on its own and jerk you forward. I can park the car and the next day will run perfect then for 2 weeks straight it acts up then stop again then start again. Have spoke with GM personally and they say they have never heard of this problem and no one has complained about it which I find to be a lie considering there is a rep from GM responding to people's post on here. I have taken the Tahoe in 8 different times and after 2000.00 replacing the ecm, bcm, negative battery cable, fuel pump, fuel pump module it is still tore up. Have reprogrammed the computers and still no change. Any ideas??? Anyone find what works??? Please help!!!

I just had those same problems come up with my Tahoe. It has been doing it for the last 2 days. The locks go haywire while I am driving. It loses power out of nowhere and even pushing on the brakes or gas will not help it go anywhere. The lights and the dashboard go crazy, flickering lights everywhere. It jerks really bad. It lasts for a few seconds to a few minutes and then it's fine. It is very scary. This happened to me on the freeway. I'm trying to get in with the dealer to get it checked out too. If you hear of anything, let me know. I will do the same if I have any luck.

I also have been experiencing this in my 2011 Tahoe. Today the locks went haywire, no power. Luckily I was in a parking lot  Shut it off, went shopping and then it was fine. I thought maybe it was my battery going bad, so I took it to an auto parts store and the battery and alternator tested fine. Got home and it started acting up again and after turning it off it would not start back up. Waited about 5 minutes and it was back to running fine. Mine is a old police vehicle I bought at auction and I replaced the factory radio, so in an effort to resolve this, I removed my aftermarket stereo and noticed some wires that weren't completely taped off in the dash from when it was a police cruiser. Taped up the bare wires and my fingers are crossed.

I have the same problems with my Tahoe, how did you resolve the issue?

Check your grounds---battery cables and engine-to-frame grounds. It's one of the first things you want to do when your electrical system starts to act weirdly.
