    They almost got away

    https://owlcam.com Like a Ring doorbell for your car. No affiliation with them, just read an article recently where an NFL lineman nearly strangled a guy in his car and this is how he was alerted.

    08 Hybrid At low speed jolt cutout lerch and get codes P061B & P0AC4

    First check the 12V battery....if it is even the slightest bit weak, replace it....a weak 12v battery causes the hybrid/computer system to go bonkers. Since it doesn't start the vehicle, you will never know until it's completely dead. I recently checked mine and it had 136 CCA from a stated...

    Comtemplating 08 Hybrid, 80k miles

    I would not recommend a Hybrid over a clean regular Tahoe. A new authentic GM (not re manufactured) hybrid battery is $3700(part only), maybe around $3000 if you can get a good deal....however, they are currently not available, they have been on back order for several months with no definitive...

    Actual hp

    My understanding is the ICE is 332 HP and there are two 50 HP DC motors in the transmission equaling 432 HP. However it probably isn't that easy to calculate given how the two systems interact with one another, it's doubtful they both operate at 100% at the same time. The hand off between...

    Service Hybrid system, traction control, stabletrak, and brake system message

    Check the 12V battery, regardless of age, load test it. It may appear to be fine if you just check the voltage but will drop to zero under a load indicating a possible shorted cell. The symptoms you mention are common for a weak 12V battery. The Hybrid computer modules go haywire with a weak 12v...
