Took the car to dealer on Monday morning and the finally called me today (Wednesday) and said car is ready to be picked up. They said the issue was a bad ECM/PCM (Engine Control Module or Powertrain Control Module). This is what the ECM does:

"The engine control management computer, also called the engine control module (ECM) or the powertrain control module (PCM), is a modern computer that receives inputs from nearly every system on the vehicle, and instantaneously uses that information to deliver appropriate engine power for operating conditions."

I am glad this car is leased and under warranty.

Thanks for posting this problem and fix.

Here is the actual message on the dash. Also the yellow warning light with the exclamation mark has been there for a while now. The dealer finally checked it and it has to do with "automatic air vents" in front of the car, I guess its broken. The dealer will also replace that part.

OK, I'll bite! The car is parked on your driveway and will not start. How did the broken "automatic air vents" kill the car? Did something over-heat while the car was parked? I do not know anything about the automatic air vents other than they are electrically operated. Perhaps, being broken, they were stuck and kept drawing 12 volt power even with the car powered off. If true, this would eventually drain the 12 volt battery and kill the car.



Sorry for being vague about my post. I'll try to explain better:

For months before the spark "died", I have had that yellow warning light on the dash. Been ignoring it and postponing a trip to the dealer until about a month ago I had to take it in because of the "airbag issue". Aside from the recall, I told dealer to check what the warning light is about.

Once I got the car back on the same day, the recall was performed and the dealer said that the warning light is due to a malfunctioning "Active Grill Shutter". To explain what this is: [In order to improve the aerodynamics and maximize thermal efficiencies the Spark EV employs an Active Grille Shutter system. The system includes a motorized actuator that closes louvers at the front bumper to enhance vehicle aerodynamics in driving situations where cooling and A/C loads are relatively low and high levels of front end airflow are not required. The engine control module determines shutter state based on various vehicle conditions such as vehicle speed, coolant temperature, fan state, refrigerant system pressure, A/C compressor state and ambient temperature. If high levels of airflow are required the active grille air shutter actuator opens the louvers.]

The dealer did not have this "part" of the active shutter available and told me to come back once they order the part. Last week, I was getting "Propulsion power reduced" randomly. The car would still start after several on/off. Finally yesterday, I was trying to back out of my driveway and got that message again. But this time it won't start anymore no matter how much I did the on/off cycle -All electricals still worked (headlights, radio, etc). That is when I finally called roadside assistance to get it towed to dealer.

So the car is on its second day at the dealer and haven't heard from them yet. They are to do two things: Check why the car won't start anymore and also install the new "part" for the active grille. Is the broken active grille responsible for the no propulsion? I don't know, but I am leaning more to both things as a coincidence.

Ill post updates once I hear back from dealer, hopefully today.


I had to laugh today. I had previously commented on this post. So....today, on my way home, the Yellow Service Vehicle Soon warning light came on but nothing showed up on the display - very similar to what I read above. I had OnStar do a scan but nothing showed up although the OnStar person said something about an electric motor.

Both my 2014 Spark EV and 2015 Spark EV are currently charging in 100 deg. F heat. The Active grill is OPEN on the 2015 Spark EV and CLOSED on the 2014 Spark EV with the fan(s) running.

I will take the car in tomorrow and have them check out this problem and I plan to mention that it might be the shutter motor or the ECM. I will update when I get the answer.

Yeah, that can't be right.
If it was not covered by warranty I know I'd MacGyver those shutters permanently open. :lol:

This morning I checked the grill and the shutter was still closed. I powered on the car and the Service Vehicle Soon warning light was now off. I backed out, left the car powered on and checked the grill again - the shutter was still closed. So, I drove 17 miles to the dealer, talked to the service advisor and set up an appointment for Thursday. Then, I drove home and checked the grill again - now the shutter was open and seems to be working correctly. I will have to keep an eye on this to see if the shutter continues working correctly.

Just wondering if replacing the ECM/PCM solved all the issues. My 2016 spark is now randomly showing the "reduced propulsion" message even though there's plenty of charge remaining. I'll be taking it to the dealer next week, but was just hoping to get better idea as to whether replacing that module will take care of it.

Did you end up having the same source of the issue?

They told me the battery pack was bad, and they're in the process of replacing it now. It's been almost a month since they've had my car. In the meantime, I'm forced to drive around in a Chevy Equinox loaner. I'm trying to figure out how much compensation to ask for when they finally do complete the repair.

Dang, how long does it take to ship a container from the warehouse??
If you bought this new ,, The Lemon Law Clock is running....
If not, sit back and relax, while buying that smelly stuff for your loaner.
