Please help...

I was driving to work a few minutes ago, and my service stabilitrack and service traction control light came on. Also it said my engine power was reduced. Luckly I was only a mile from work when it happened, but this seems like a serious problem. My Tahoe would not go over 30 mph after the service lights came on. Does anyone know what may have happened or how to fix it?

This is a 07 Tahoe LT 5.3

Thanks

It is possible that a wire connection rattled loose somewhere, OR something bad happened in the motor.

I would advise a trip to the stealership.

I would start by figuring out what codes your vehicle is providing. This will help to narrow the problem down.

Here are some of the things it could be -

1. Traction Control/ABS Sensors: Just one of these little buggers can set off enough lights to light up a runway. Many times you get a bad/inoperative sensor, or one of the sensors has come come unplugged. Check the wires around the brake and where the connectors are located.

2. Throttle Body and/or Throttle Body Sensors: A problem with the Throttle Body and/or its sensors can cause precisely the issues you have described.

3. Faulty Air Intake: The plastic on these intakes can wear down over time and fracture. The fracturing causes small plastic particles to enter the engine, and as a defense mechanism the computer shuts down stabilitrak, and reduces engine power to prevent damage.

Of course, there could be other issues, but these are the ones I am aware of. Either way, it may be best to take it to a dealer/mechanic and have them run the codes and look it over. Good Luck!

Same thing happened to me on an 09 Yukon with 40k mikes over thanksgiving.

I took it to the dealer and they replaced the throttle body. No more issues and it was all under warranty.

Good luck!

Thanks to the people who actually tried to help. I'm going to take it by the dealership tomorrow

On topic see what the dealer says and tell us if you find out so we can help others if they have a similar problem and if not im sure sunlit might have some ideas on what it could be

Thread cleaned up and troll is bye bye.

OP, it looks like you've gotten some good info already but this has happened to me twice, as well. Once was due to my intake too need to be reattached to the throttle body. The other time I accidentally unplug one of the connections along the frame rail when installing new rear shocks. So there's some other things to think about

Well Guys, I am once again sorry for my outburst which has obviously been deleted by now. I just could not stand it any longer to have this guy constanlty bash our trucks.

I am sorry he is having issues with his, but these could be described in a more pro-active as well as professional manner.

THANKS!

I have a Durango to drive too! ...but that is because it is work provided. I CHOOSE to have my Tahoe!

Bino, that happened to me, it gave me a cel of P0121 and P2135, which is the throttle body. I know there is a bulletin for that. Check with the dealer. They might replace the throttle body.

Now that I think about it more my dad had it happen to him on his '10 silvy and the dealer had to replace his throttle body under warranty and stated it was a known issue. I'm not clear why the throttle body messes with STABILITRAK but it does

Thanks. Hopefully it's not to expensive to fix bc my truck just hit 100,500 miles...
