2014 Chevrolet Volt Fuel System Problems

Your car suddenly stopped working at a stoplight with only a brief "Propulsion power is reduced" warning message beforehand. After restarting, the car barely limped out of traffic and became nearly impossible to shift into neutral for towing. The dealer resolved the issue by replacing the engine control module.

Your car's engine power feels noticeably weaker than normal. This reduced propulsion could affect acceleration and overall driving performance. A mechanic will likely need to diagnose the fuel system, ignition system, or engine controls to identify and fix the underlying cause.

Your car is losing power while driving and moving slower than normal. This could indicate an issue with the engine or propulsion system that needs diagnostic evaluation. A mechanic will likely need to scan the vehicle's computer and inspect the fuel and ignition systems to identify the cause.

ON 2/17/2020, I WAS DRIVING ON I-5 NORTHBOUND AT ABOUT 10 PM NEAR BURLINGTON, WA. MY SPEED WAS ABOUT 60 MPH ON A RELATIVELY FLAT HIGHWAY. WEATHER WAS NORMAL FOR THE TIME. NO RAIN, NO WIND. SHORTLY AFTER MY CAR SWITCHED FROM THE ELECTRIC-POWERED OVER TO GAS-POWERED, THE CAR STARTED TO REV VERY HIGH AND QUICKLY DECELERATED EVEN THOUGH MY FOOT WAS FULLY PRESSED ON THE ACCELERATOR PEDAL. "PROPULSION POWER REDUCED" MESSAGE CAME ON, FOLLOWED BY "ENGINE NOT AVAILABLE, SERVICE SOON" MESSAGE CAME ON. THE CEL ALSO CAME ON. I HAD NEVER SEEN THESE MESSAGES BEFORE. SEMI-TRUCKS WERE BEARING DOWN ON ME FROM BEHIND. IT WAS A VERY DANGEROUS SITUATION. LUCKILY, I WAS ABLE TO COAST TO THE RIGHT SHOULDER WITHOUT ANY CAR DAMAGE OR INJURY. EASILY THIS COULD HAVE BEEN MORE SERIOUS DAMAGE AND/OR INJURY IF THERE WAS MORE TRAFFIC NEARBY OR I STALLED IN THE TRAFFIC LANES. I WAS ABLE TO RE-START CAR AT ABOUT 10 MINUTES AND SLOWLY DROVE HOME AT A VERY REDUCED SPEED. SUBSEQUENTLY, MY CAR SEEMED TO DRIVE FINE. BUT EVERY TIME THE CAR GOES FROM ELECTRIC TO GAS, I GET NERVOUS THAT THIS INCIDENT WILL REOCCUR AND CAUSE AN ACCIDENT. MANY TIMES, THE HIGH REV WILL START AND THE "PROPULSION POWER REDUCED" MESSAGE COMES ON AND THE CAR DECELERATES BUT THANKFULLY THE CAR HAS NOT COMPLETELY LOST POWER LIKE THE FIRST INCIDENT. ABOUT 1 MONTH LATER, I TOOK THE CAR TO A CHEVROLET DEALERSHIP FOR DIAGNOSTICS. THE CEL WENT OUT PRIOR. THEY COULD NOT FIND ANY FAULTS AND SAID EVERYTHING WAS NORMAL. NOTHING WAS STORED IN MEMORY. THEY COULD NOT REPRODUCE THE PROBLEM IN THE SHOP. THE "PROPULSION POWER REDUCED" MESSAGE HAS APPEARED AGAIN AFTER SERVICING. I AM FEARFUL TO DRIVE THIS CAR.

LOSS OF PROPULSION POWER. CAR ALMOST SHUT OFF WAS ABLE TO PULL OVER. WAS GOING UP ON A VERY SMALL HILL ON THE HIGHWAY. CAR WAS SEEN LAST YEAR FOR THE SOFTWARE UPDATE HOWEVER LOSS OF PROPULSION HAPPENED AGAIN.

TL* THE CONTACT OWNS A 2014 CHEVROLET VOLT. WHILE DRIVING 65 MPH, THE PROPULSION POWER REDUCED WARNING INDICATOR ILLUMINATED AND THE VEHICLE DECELERATED TO 35 MPH. THE VEHICLE WAS PULLED OFF THE ROAD AND THE BATTERY DIED. THE VEHICLE WAS TOWED TO MIAMI LAKES AUTO MALL (16600 NW 57TH AVE, MIAMI LAKES, FL 33014, (305) 455-3540) WHERE IT WAS DIAGNOSED THAT THE SOFTWARE TO THE PROPULSION SYSTEM NEED TO BE UPDATED. THE SOFTWARE UPDATE WAS PERFORMED, BUT THE FAILURE RECURRED THREE TIMES. THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 53,016.

WHILE DRIVING AT 45 MPH, THE VEHICLE BATTERY SYSTEM TURNED OFF LOSING THE ABILITY TO ACCELERATE. THE ENGINE DID NOT TURN ON WHEN THE BATTERY DRAINS TO ZERO. THE BATTERY WAS FULLY CHARGED AT ABOUT 95% WITH ABOUT 40 MILES OF RANGE REMAINING. THE GAS TANK WAS 3/4 FULL. HAD TO COME TO A COMPLETE STOP IN TRAFFIC, PLACE THE CAR INTO PARK, TURN OFF THE CAR COMPLETELY THEN BEGIN RESTARTING IT FOR ALL FUNCTIONALITY TO RETURN.

ON JUNE 4, 2018 I WAS DRIVING WITH 4 MILES LEFT OF ELECTRICITY POWER, ONCE I RAN OUT OF ELECTRICITY IT SWITCHED OVER TO THE GASOLINE TANK WHICH WAS HALF FULL. ONCE THIS SWITCH OCCURED I RECEIVED THE MESSAGE ON THE DASHBOARD THAT READ "PROPULSION POWER REDUCED" AND "ENGINE NOT AVAILABLE, SERVICE SOON". I WAS DRVING ON A REGULAR FLAT STREET (NO STEEP HILLS) FOR ABOUT 15 MINUTES THEN WENT INTO FREEWAY. ONCE IN THE FREEWAY MY VEHICLE BEGAN TO SLOW DOWN SIGNIFICANTLY GIVING ME JUST ENOUGHT TIME TO PULL OVER TO THE RIGHT SHOULDER LANE. I WAS VERY LUCKY TO HAVE BEEN ABLE TO PULL ALL THE WAY TO THE RIGHT WHICH IN PART WAS DUE TO THE FACT THAT I WAS ALREADY ON THE RIGHT LANE, BUT IF I HAD BEEN ON THE LEFT LANE I CAN GUARANTEE I WOULD NOT HAVE MADE IT SAFELY TO THE SHOULDER LANE. PRIOR TO THIS I HAVE HAD ABSOLUTELY NO OTHER ISSUES WITH THE VEHICLE. ON MARCH 26, 2018 I TOOK MY VEHICLE TO THE DEALERSHIP WERE IT WAS PURCHASED FOR AN OIL CHANGE AND FOR A COMPLETE CHECK AND ALL RESULTS WERE NORMAL.

WHILE IN FULL MOTION ON THE HIGHWAY, THE CAR SUDDENLY DECELERATED TO 5 MPH DESPITE PRESSING ON THE ACCELERATOR AND THEN A MINUTE OR TWO LATER COMPLETED STALLED OUT. TWO ERROR MESSAGES: ENGINE NOT AVAILABLE, SERVICE SOON AND PROPULSION POWER IS REDUCED. AN EARLIER INCIDENT, A FEW MONTHS AGO, WHILE ACCELERATING UP A SLIGHT INCLINE, THE CAR DECELERATED TO A FEW MILES PER HOUR DESPITE PRESSING ON THE ACCELERATOR.
