I am having the issue of "TRACTION CONTROL OFF, SERVICE TRACTION CONTROL, SERVICE STABILTRAC, AWD OFF" first intermittently now permanently. There is no CEL.
I have read extensively across the Lambda network forums and have determined that there is not necessarily a connection of this error with the braking/TC systems. Some have posted issues with Timing chains, heads/cams, ignition issues.(with CEL) For other posts, there are no conclusion as to what the final outcome was to correct this issue.
-The vehicle was fully inspected and no problems found
-I have checked wheel sensors visually (Front) for damage and metallic debris as per TSB
-All brakes are 90% new and fluid is fluid and changed 6 months ago
-Dealer code scan...no codes (before the permanent onset of the warnings)
-No other performance issues noted (other than the lack of TC/ABS/Stabiltrack and AWD features
I would like to hear your issue and official solution as I am spending too much time at the dealer without answers.
My PT warranty and extended is over in two weeks and not sure if this could be minor (wheel sensor/bearing) or major (cam, timing chain, transmission etc) in nature
Starting here, because I'm clueless as to where else to start...
2010 Acadia SLT - 120k miles
I started having issues with the same (Service Stabiltrak, Service Traction Control, Traction Control Off) along with some others, like my Remote Start just stopped working (the same time as the Service S, TC warnings came up), and Service Air Bag. I didn't notice any really weird things when driving, other than ONLY when I turned left it would get a really odd ... Airy ... sound to it.
Ran the codes, only one that popped up was the MAF sensor. Made plans to address the issue, but before the weekend came around I started getting rough driving, the engine would stutter randomly, for a few days, then nothing for a few days... ending with a crank no start on a Friday after work. It would TRY to start, but just sounded whiny and not fully into committing to the start.
That evening it was looked out by a knowledgeable friend... who discovered oil in the intake, MAF. Had it towed the next morning to where it now sits. The spark plugs were all horribly fouled. Replaced all those, and the MAF sensor. Hooked everything back up, Still Crank no Start. Just doing a little trouble-shooting, we discovered that if we pulled off the Purge Valve it would start, roughly, but die after a second or two. I (through my sub par research decided it needed a new TB so I got one). We could hear/feel the new one working (whereas the old one wasn't), and it would start, just not stay on.
It sounds like the timing is off, and the new code that popped up is P0336, and the Service Stabiltrak/Traction Control Off messages have gone away. Service Airbag is still there. (the plan is to test/change the crankshaft position sensor - I just have a feeling that won't help and I'll just end up having to try to diagnose another possible reason my car won't start and/or stay running).
OH! I forgot... there is an obvious drain on my battery. The battery is good. I had to charge it over night (due to the drain), it held a charge all day, I then took it to where I bought it from for them to do a load test, they tested it with 3 different battery testers (the last being called "The battery Killer") and it tested good. 886 *cranking amps I think* with the Battery Killer. I took it home, hooked it up, it cranked/started for 2 secs before it died out. It sounded like my lawnmower when I run out of gas. (No other way to describe it). It has that 'fading' engine die. AND!! (another thing I forgot to mention) My GAS drops quick. I was one line above half a tank in the AM, drove it less than 3 miles and it was on half a tank when I got int it again. Apparently, attempting to start it multiple times (though, not really all that much) over the past week has used a lot of gas, (or it's just not gauging correctly?) because its in between 1/2 and 1/4 now.
I've tried to research... A LOT... and all I've found is a million different possible reasons with just as many possible solutions. So I thought I'd try actually posting to see if one of you Gurus could offer ideas/suggestions - other than taking it to the dealer.
