    Wondering if there is a way to manually start the ICE on the PHEV. Like when you are sitting on the driveway and the battery is charged but you want to start the engine anyway just for troubleshooting or general inspections.

  4. 2008-2013 CTS General Discussion
    So, I have a 2009 Cadillac CTS with the 3.6L V6 and the engine just blew. I’m wondering if I can swap the motor with a 04-05 CTS engine with the same motor. I guess the question is are they the same motor and will it fit? I matched my vin number if that even means a thing. Thank you guys in advance!

The thought just popped into my head this evening and before I spend a bunch of time researching I wanted to see if anyone else who knows more about this kind...

    Yesterday was the first time the car switched over to ICE soon after a fresh charge. The battery is now 7 years old. Warranty until September, 2022. I purchased the car exactly 4 years ago. I also am noticing the mileage range on a full charge gas dropped. In first year, I was getting 32-34...

    O2 sensors have welding beads on metal to metal contact, already was told the exhaust manifold gasket and all 3 o2 sensors need to be changed.

    How well does the cylinder deactivation work on the V6 twin-turbo? Is there an indication on the instrument panel when it is activated? Also, does anyone know if it's always the same cylinder(s) that are deactivated? I can find very little information on this feature, other than that it exists...

    I have a friend with an '08 Escalade which has a strange problem starting after sitting overnight, sometimes it'll crank fine for a couple seconds then all the sudden slow down before the engine finally catches.
