Ever since I brought my Volt into the dealership for the most recent recall my car has been abruptly switching to ICE during hard acceleration. I?ll try to start off slow from a red light but when it gets to about 60kw it randomly shuts off switches to the gas motor and creeps along at 20mph until it figures out that it has a full battery again. This process takes about 20 seconds and can be quite dangerous. The check engine light has not come on.

open and close the hood - ?

Yeah, it could be a loose hood causing the sensor to read open when accelerating (not sure if there's a hood-open speed limit or anything), but if that doesn't immediately solve it, definitely take it back to the dealer. Honestly the hood thing sounds like the best bet because they would have had it open, and if it's not lighting up the CEL, it's some sort of "expected behavior".

Of course, it could also be a damaged hood latch or sensor, which is a much more difficult problem to fix.

It sounds like something more serious to me - even if the ICE were to engage because the hood is open, it shouldn't creep along at 20 mph for 20 seconds. The ICE would just engage and you would keep driving normally. My car has never taken that long to switch over.

Bring it back to the dealer, no benefit in trying to armchair quarterback the problem here, especially if it cropped up after something they did. Let them figure it out.

^^^^This is good advice.

Wouldn't a damaged hood latch switch/sensor cause it to indicate the hood is open when it thinks it is? If the OP isn't seeing any messages indicating such then I would suspect something with the powertrain rather than a switch. It seems to me like this is an issue that can certainly be duplicated for a tech and due to the safety concerns should not be released back to the customer until it's solved.

Contact OnStar, ask them to retrieve any error codes that they can for your Volt. Bring this information with you when you take your Volt to a qualified Chevrolet Volt service center.

Good morning, Voltdaily80!

At your earliest convenience, could you shoot me an email with your VIN, contact information, preferred dealer name and your current vehicle mileage? This certainly doesn't sound right, and we'd like to look into this situation further on our end with your dealership.

Best,

Amber G.
