i have a 2008 GMC Sierra 1500 SLE. The other day i was driving around town and out of no where my check engine light starts flashing, it says service stabilitrak and traction control. Wont stop flashing and will keep kicking the traction control and stabilatrak on/off. Anyone have an idea why?

Did you put a code reader on it? It could be a lot of things.

I have been having the same problems with my 2007 Silverado. when I am stopped at a light or in slow moving traffic, the traction control light comes on and the hard first gear shift fallows. I have taken my truck to a trans shop and was told it was not the trans. I took it to a another shop and the only answer I got was a few maybe's but ended with a "im not really sure". From all the research I have been doing, this is not a small isolated problem. the only thing I would like to add is I can get the light to go off by bringing up the RPM when at a stop and the light will go off and if I time it right it stays off long enough for me to start driving before it comes back on again. I would love to know if anyone has figured this out yet or are we stuck spending hundreds of dollars on replacing parts until someone gets lucky enough to replace the right part. it is a very frustrating situation.

The big thing is GM wont stand behind it. I tell everyone that I know not to buy anymore gm vehicles. Our 07 Yukon does the same thing and they wont do anything about it.

There are a lot of reasons for the stabilitrak non-sense. In my case it was a fouled plug. The error trapping by making your car run like **** or worse with the stabilitrak error is to purposely make you bring it into the dealer. Once you fix the underlying problem, it will go away. In my case it was a $2 spark plug, which by the way pointed to a more serious issue. See the TSB Below. BTW, my Suburban still sucks oil like a freighter. I wonder Where Louis Chevrolet is? Normally they chime in here.

#10-06-01-008B: Engine Oil Consumption on Aluminum Block Engines with Active Fuel Management (AFM) (Install AFM Oil Deflector and Clean Carbon from Cylinder) - (Mar 7, 2011)

This bulletin is being revised to add the 2009 model year and new Correction information for the 2009 model year - left rocker arm cover replacement. Information has also been added after step 9. Please discard Corporate Bulletin Number 10-06-01-008A (Section 06 - Engine/Propulsion System).


--------------------------------------------------------------------------------
Condition
Some customers may comment about engine oil consumption of vehicles with higher mileage (approximately 48,000 to 64,000 km (30,000 to 40,000 mi). Verify that the induction system is assembled correctly and that there is no evidence that the engine has been ingesting dirty air due to a mis-assembled induction system. Also verify that the PCV system is functioning properly. If diagnostic procedures indicate that oil consumption is piston/piston ring related, verify that oil consumption is less than 3,000 km (2,000 mi) per liter/quart. If these conditions are met and oil consumption is less than 3,000 km (2,000 mi) per liter/quart, perform the service indicated in this bulletin.

Cause
This condition may be caused by oil spray that is discharged from the AFM pressure relief valve within the crankcase. Under most driving conditions and drive cycles, the discharged oil does not cause a problem. Under certain drive cycles (extended high engine speed operation), in combination with parts at the high end of their tolerance specification, the oil spray quantity may be more than usual, resulting in excessive deposit formation in the piston ring grooves, causing increased oil consumption.

Correction
2009 Vehicles Only
Important: This left rocker arm cover is NOT to be used on 2007-2008 vehicles because of the calibration of the PCV orifice being different in 2007-2008.

A new left rocker arm cover has been released for 2009 engines. Technicians should replace the left rocker arm cover with GM P/N 12642655. This rocker arm cover has relocated PCV drain holes that prevents PCV pullover into the intake manifold. Refer to SI for Valve Rocker Arm Cover Replacement - Left Side.

2008-2007 Vehicles Only


To correct this condition, perform the piston cleaning procedure as described in this document, and install a shield over the AFM pressure relief valve per the procedure outlined in this document. Monitor oil consumption after this repair to ensure oil consumption has improved to acceptable levels. If this repair does not correct the condition, it may be necessary to replace the piston assemblies (piston and rings) with new parts.

Important: It is critical in this cleaning process that the engine/fuel injector cleaner remain in the cylinders for a minimum of 2.5 hours to fully clean the components. The cleaner solution must be removed before a maximum of three hours.

•Verify the oil consumption concern following Corporate Bulletin Number 01-06-01-011F. If oil consumption is found, continue on with this bulletin.
•Remove the spark plugs and ensure that none of the pistons are at top dead center (TDC).
•Clean the pistons by putting 118-147 ml (4-5 oz) of Upper Engine and Fuel Injector Cleaner, GM P/N 88861802 (in Canada, use 88861804), in each cylinder. Allow the material to soak for at least 2.5-3.0 hours, but no more than three hours and then remove the cleaner. A suggested method of removing the cleaner is cranking engine over. Make sure to unplug the ignition coils and fuel injector before cranking the engine over. Also make sure that the painted surfaces are covered so no damage is done.
•Remove the oil pan. Refer to Oil Pan Replacement in SI.

•Remove the AFM valve (1).

•Install the new shield (1), GM P/N 12639759, and tighten the AFM valve to the oil pan to 28 N·m (20 lb ft).
Important: Ensure that the engine cleaner is thoroughly removed before reinstalling the spark plugs. Failure to do so may result in a hydro-lock condition.

•Reinstall the spark plugs. Replace the spark plugs if necessary due to full of carbon. Refer to the parts catalog.
•Reinstall the oil pan. Refer to the Oil Pan Installation procedure in SI. Replace the oil pan gasket if necessary. Refer to the parts catalog. Replace the engine oil if necessary.
•Re-evaluate the oil consumption. Document on the repair order. If the oil consumption is still greater than 0.946 L (1 qt) in 3,200 km (2000 mi), replacement of the pistons and rings will be required.


Important: Some minor scratches may be noticed on the cylinder walls during piston and ring replacement. If the scratch cannot be felt when running your finger nail over it, the scratch is considered normal wear and the block or engine should not be replaced.

Most mechanics won't do this. Go to an electrical place and have them do a complete check. There may be a short somewhere like in my case. I had two shorts that caused my ABS, T/C and E-brake lights to come on. My mechanic took the time to check, found them and fixed them. The lights do not come on anymore.

Could be the throttle body sensor. It's integral to the issues you mentioned.

Hello, I am the original owner of my 2007 Tahoe and I have been having this issues with traction control system six months into ownership. Now it is 2015 and I am out of warranty and have had this issue at least 5 times in the past seven years. The Chevy service guys have never gave a clear answer to WHY🔥😮. Can I get a do it your self solution I can't afford to bring my car in every other year for the same problem.
VIN # 1GNFK13027J217230

Also I cannot relearn my security remote or tire sensors

Welcome to the forum...

Lets start with the tire pressure sensors, so you rotated your tires and when you do the learn process it times out or the horn never chirps, or you you have a TPMS light on the dash and the relearn won't fix it?
If its the latter the sensor is probably bad and needs to be replaced.

Same for the remote, have you put fresh batteries in the remote, is it the factory remote or after-market...

The traction control could be a bad wheel speed sensor or a connection anywhere along the wiring harness... What are the codes if any that are being stored? Are you getting the reduced engine power in addition to the TC, if so it could be a throttle body issue or a number of other items as the TC and reduced engine power can be a catch all error for things the computer can't identify so we would need to know any stored codes...

Ok as for the the tire monitoring system, it reads only dashes no numbers.
As for my alarm relearning yes the first thing I did was replace the battery in both transponders. This is the original remote,
Both alarm and tire monitor will not relearn with I push and hold the button. The horn do not chirp for neither.
I will get codes today Wednsday when I get off work. Now I can tell u this the problem came back when I put air in my tires

As for my traction control, there is no loss of power, and I have cleaned the the throttle body, and changed air filter. The problem is intermittent. I can go a few miles or a day and it want come on.i did however put air in my tires and that seems around the time the problem started.

Also my rear cigarette lighter (as they use to be called) are not working the one located in the middle partition storage facing rear passengers and the one in the tailgate section has never worked. I checked all known fuses. The one inside the middle storage works fine.
