2016 CHEVROLET VOLT Vehicle Speed Control Problems

This vehicle has had multiple incidents of surging of the propulsion system both on battery power and when powered by the internal combustion engine, causing loss of propulsion and sudden acceleration almost causing collisions multiple times. We have paid for over $4,000 in repairs that are not covered under the propulsion system warranty, and these repairs have not remedied the issue.

I bought the car new in 2015 and after about only 40,000 miles I began getting a Propulsion Reduced error and the car would have very slow acceleration. I took it to the dealer and they replaced the accelerator for $500. It drove fine for a month, but then the acceleration was reduced again. I took it back to the dealer and they were stumped. They wanted to charge me $1300 just to replace some wires, but they weren't confident that would fix the problem. I declined. As it stands now I can toggle the F08 fuse and that temporarily fixes it for about an hour or so, but the error always comes back and the car has a hard time accelerating. Not safe. I called GM and they suggest I take it to another Chevrolet dealer, so I'm going to do that. I'm also going to reference NHSTA Special...

This vehicle has been intermittently displaying shift to park, reduced propulsion and loss of power. Chevrolet will not address its problems utilizing the March 6, 2024 service bulletin that covers this model year despite it exhibiting these dangerous warnings and reduced power and stoppage. Please help!

My car will lose all power as I'm driving, switch between gas/ elec and almost stall, it will accelerate when I take my foot OFF the gas , it will lose power on a turn.. it's random. form what I understand it's the BECM and it happened just after 100k miles. I have 105k.

UN-COMMANDED VEHICLE ACCELERATION UNDER FULL ELECTRIC DRIVE MODE (TWICE). WHILE DRIVING STEADY AROUND 65 MPH ON THE FREEWAY (NO CRUISE CONTROL USED), A SLIGHT STEP ON THE ACCELERATOR, CAUSED THE CAR IMMEDIATELY ACCELERATED UP TO 88 MPH (DASH SHOW LARGE ELECTRICAL DRAW OF BATTERY POWER). STEPPING ON THE BRAKE, USING THE REGEN PADDLE ON THE STEERING WHEEL AND REPEATED PRESSING THE CRUISE CONTROL POWER DIDN'T DISENGAGE THE POWER SURGE. CAR WOULD ACCELERATE WHEN BRAKE PRESSURE WAS LIFTED. AFTER REPEATED HARD PRESSING OF THE BRAKE PEDAL, THERE WAS A "CLACK" SOUND FROM BELOW THE DRIVER CONSOLE AND THE CAR RETURNED TO NORMAL. BEING ON THE FREEWAY, I WAS NOT ABLE TO PULL OVER AND RESTART/REBOOT THE CAR. I CONTINUED TO DRIVE CAUTIOUSLY, MONITORING THE CAR AND LEFT THE FREEWAY FOR SURFACE STREETS. EVERYTHING SEEMED TO BE OKAY UNTIL I CAME TO A COMPLETE STOP BEHIND TRAFFIC. WHEN TRAFFIC STARTED MOVING AGAIN,...

THERE'S AN ODD SITUATION WHEN I'M IN THE ELECTRIC MODE AND AM PASSING OVER A BUMPY BIT OF ROAD: THE VEHICLE ACCELERATES AUTOMATICALLY. THE PART THAT IS TROUBLING IS THAT THESE ARE TIMES WHEN THE DRIVER WOULD WANT TO SLOW DOWN. IT HAS HAPPENED TO ME MANY TIMES. I'VE BEEN LUCKY, SO FAR. BUT I HOPE THIS IS REMEDIED SOON.
