  4. Problems, Driver Warnings or DTCs - Gen 1 Volt
    My 2012 Volt broke down and the dealership is quoting me $7500 for repairs. They would replace the motor 1? in the transmission and the AC compressor. To make a long story short my Volt coasted to a stop and would never turn back on, this was after a self-repair on the bearing that makes the...

  6. Problems, Driver Warnings or DTCs - Gen 1 Volt
    "Engine Unavailable" error & no help from Chevy to cover Transmission repair What up fellow Volt owners: I'm frustrated, sad, and looking for any last glimmer or hope or even just a place to vent. I purchased my 2012 volt from a dealer here in CA just three years ago at about 70,000 miles...
  7. Use, Care & Maintenance - Gen 1 Chevy Volt
    Just changed my transmission fluid a little early at about 94k miles. Everything went smoothly except for it seems like more than the recommended ~6 qts came out so I assume that means they slightly overfilled at the factory. My concern is after I finished the fluid change, driving home I...
  8. Generation 1 Chevy Volt (2011-2015)
    I recently a transmission bearing in my 2012 Chevy Volt. The dealership said I am out of warrantry, so I paid out of pocket. Now I have my doubts, as I read in some places that "transmission" is considered part of voltec... Can someone clarify if "transmission m2 bearing" is covered by 8yrs/160k...
  9. Problems, Driver Warnings or DTCs - Gen 2 Volt
    Does anyone else notice a buzzy vibration when the ICE is used while accelerating slowly? I can hear it and also feel it, most noticeable through the steering wheel. It is especially noticeable between 35 and 50 MPH. When acceleration stops and I hold speed constant the buzz will continue for...
  10. Problems, Driver Warnings or DTCs - Gen 1 Volt
    My Volt 2012 with ~ 120K miles broke down last week on the road. Got the bad news from the dealer today: Stating that the transmission needs to be replaced and costs about ~7,000.00 Almost the value of the car. Car was 5 weeks ago in for oil change and checkup. Nothing unusual regarding the...
  11. Problems, Driver Warnings or DTCs - Gen 2 Volt
    I would like to share an issue I experienced on Friday May 5th. While traveling to work, my 2017 Volt LT turned on the engine check light and requested me to shift to Park. It then slowly become unresponsive to the accelerator and I had to pull it to the side of the road. I tried to turn off and...
  12. Generation 1 Chevy Volt (2011-2015)
    https://www.youtube.com/watch?v=dqM3YXEf1js Good video showing the internal parts. The Gen 1 is really a very clever design. Couple of things I really like: Use of 2 electric motors Use of "Clutch packs" for engaging or stopping rotating parts vs one way clutches on Fords. Plus geared final...
  13. Problems, Driver Warnings or DTCs - Gen 2 Volt
    2016 Volt, produced October 2015, about 500 miles on engine, 17,600 total, car died. At dealer for 10 days total, Transmission replaced. Back to normal. Here are the 16 codes that were thrown and you probably don't want to ever see all at once: p0ac4 p1af0 p1af2 p1bob p1b43 p1e1e p1e22 p0a46...
  14. Use, Care & Maintenance - Gen 2 Chevy Volt
    Hi! Just purchased a used 2016 Volt and it's great. But I've noticed when it's in Hold Mode or even more so when the battery is completely depleted and I'm forced to use gas, I've noticed the loss of power a bit as if it's in too high of a gear sometimes. It's the equivalent feeling of if you...
  15. Generation 2 Chevy Volt (2016-2020)
    On the Gen2 output to wheels is linked to the differential by a chain. On the late 70's we had a Jeep that used a chain to couple the output from the transmission to the center diferencial (at the time called Quadra Track). In our particular case, we had to replace the chain twice in 10 years...
  16. Generation 1 Chevy Volt (2011-2015)
    So I just changed the engine oil in my 2013 Volt and noticed that this threaded plug looking thing was not fully seated and looking very peculiar. I don't think this is right. Can someone verify this is the transmission drain plug and that it's supposed to be seated or is this a feature I...
  17. Propulsion Systems - Chevy Volt
    Very interesting -- took the car to get washed today and the place was one of those old fashioned car washes where the car gets pulled along a track. -- I noticed that while the car was moving in neutral (at 1 mph...) the display said it was in regen charging. Is this why the owners manual...
  18. Suggestions for GM - Chevy Volt
    I have done lots of highway this weekend (and the past two other) On flat ground the kW consumption is quite OK when cruising at 100km/hr. However if I read the meter right, in extend mode I consume less electricity then when I run on battery for the same speed. I also feel I lost lots of...
  19. Chevy Volt Engineering and Design
    Am loving my new Volt as long as it is in Electric Mode. It's zippy, quiet and I haven't had to go to the gas station in a month. However, when it transfers over to gas usage, it starts acting strangely. Upon acceleration from a stop, it sounds as if it is stuck in "first gear". It has a...
  20. Use, Care & Maintenance - Gen 1 Chevy Volt
    Finally got my report in from Blackstone Labs. "This is the first fluid sample we've seen from the Volt's 4ET50 transaxle system, so don't put too much stock in comparing this with universal average levels yet. We started with average numbers from a similar type of transmission, but we'll...
