A lot of this happening here.
I think that you have the wrong impression. Here is a video of how the Gen 1 drivetrain works:No. There is a direct connection to the drive train at higher speeds. GM hid that for a little bit and there was a little controversy when it first came out. But, it makes sense to have the engine drive the wheels at certain speeds as that is more efficient.
There are only two volt qualified dealers/mechanics in the Portland area, one in Portland itself (google chevy dealers) and the other is in Sandy, Oregon where I just had the systems battery replaced December on my own 2012 Volt. Good luckI drove my car (chevy volt 2012) from AZ to OR. After getting past the mountain pass in Bend I stopped for gas. My car started and I got on the interstate then immediately the propulsion went out and a code said engine not available and I pulled off to the side and the check engine light was on. I called for my car to be towed to the dealership. After 5 days of no word or reply from the dealership I was told they want to run compression tests for $500 but it seems the engine needs to be replaced at a cost of $7400.
1) I know I can find an engine for cheaper than that
2) does anyone know of a mechanic who deals with volts in Portland, OR?
I would tend to argue that 150-200 might even be low....My volt is already at 135k snd still going strong (knock on wood). I;ve had 2 cars get to nearly 200k miles and the only reason they didn’t was because I had better cars, so they sat for years before I got rid of them. The 100k mark might have been true in the 80s-90s, but with the precision they can build engines today, I think the new number should be 150-200k miles. So it’s more wear and tear in the interior rather than engine wear as well as safety and tech that would cause me to trade in.
