Re: 2008 Tahoe Hybrid Codes POAC4 and P061B
UPDATE:
Finally, got a call back from GM after many days of playing phone tag. Customer Service didn't have any answers...told me to get a second opinion! Really??? I'm done with these guys. What a joke.
Hybrid was acting up today again...put the car in Reverse and CEL came on and 'reduced engine power' and 'service traction' something???

So take it or tow it to a different dealer and insist that they read ALL codes and obtain the Freeze Frames to send to GM.

Re: 2008 Tahoe Hybrid Codes POAC4 and P061B
I'm having a problem with my Tahoe Hydrid Stalling out. It happens when the engine switches from Electric mode to Gas pode particularly at a stop. The codes that show up ar POAC4 and P061B. I've taken the vehicle to the dealership numerous times and they were not able to fix it. First time they said the throttle body was dirty and it needed to be cleaned. That didn't fix it. Next time it happened they said the batteries were no good, but they couldn't work on the Hybrid
since the gloves that they use to work on Hybrid batteries had Expired. Then the next time it happened they said it was the Catalytic Converter...that was change and it still did not fix the problem. I took it in the last time just recently and they reflashed the ECM and said they still don't know what is causing the problem...they supsect it is the aftermarket wheels and tires that is causing the vehicle to stall? The advisor said that Hybrids are very sensitive when it comes the the computer and torque calculation. Does anyone have any idea of what it causing this problem???
Thanks in advance.

Below is just some additional basic info for POAC4 on the GM Hybrids,

P061B:
From the following link regarding P061B is some copy and paste basic info, https://www.autocodes.com/tsb/gmc/sierra_1500/2008.html

Re: 2008 Tahoe Hybrid Codes POAC4 and P061B
It sounds like when these two codes are offered together, a battery fix is necessary.
Interestingly, I can't get freeze frame data when my Tahoe jerks, freezes and shuts off, turning on the check engine light. By the time I can get to a dealer to get freeze frame data pulled, the light goes off, and no data is available. I don't reset it, it "fixes" itself.
I need to find a local battery refresher.
