2017 CHEVROLET VOLT Vehicle Speed Control Problems

Experiencing intermittent propulsion system failure with multiple simultaneous warning messages on 2017 Chevrolet Volt at approximately 59,000 miles. WARNINGS DISPLAYED: - "Propulsion Power Reduced" message - "Check Tire Pressure Monitoring System" (false alert - all tires properly inflated and recently replaced) - Multiple dashboard warning lights including exclamation point indicators - Vehicle exhibits abnormal driving characteristics PATTERN: Issue occurs intermittently while driving. Vehicle can be restarted and may operate normally afterward, then fault returns unpredictably. SAFETY CONCERN: This matches documented Battery Energy Control Module (BECM) failure pattern referenced in GM investigation N232432680/PE23022 and Customer Satisfaction Program 17228 recall N172096420 for reduced propulsion power in 2016-2018 Volts. Review of owner complaints shows other 2017 Volt owners experiencing sudden complete loss of propulsion while driving at highway speeds, creating dangerous situations requiring evasive action by other drivers. RISK: Loss of propulsion power while driving with dependent passengers creates serious crash risk. Vehicle...

I was driving in stop and go traffic on a relatively busy road when I was cut off. I braked hard to avoid a collision. Immediately afterwards, the car would not respond to the accelerator and would not go forward. I was in the middle of the road and the car would not respond. It could have caused an accident. I put the car into park and then back into drive and it seemed to work again. But I am now worried about the car.

The engine light starts blinking and telling me propulsion power reduced, and then I cannot use the cruise control after that turns on, and it starts losing power, driving on I 70 after work all of a sudden it turned on and wet from going 76 miles an hour to 52 on highway I 70 where the speed limit was 75. This problem was a recall problem which was fixed and now is happening again on the same part and having the same problems.

I am reporting a series of safety concerns regarding my 2017 Chevy Volt, which have persisted despite multiple attempts to address them with the dealership. These issues pose significant risks to my safety and that of others on the road. On January 18th, 2024, I brought my vehicle to the dealer after experiencing reduced propulsion power while driving on the highway, coupled with the illumination of the check engine light. The mechanic performed a quick inspection and used a GM scan tool to diagnose the issue, revealing the code P1E00 for the Hybrid Powertrain Control Module 2, which was cleared without a thorough investigation. I was advised to return if the issue reoccurred. Despite the reset, the problem persisted, and on February 9th, 2024, I scheduled another appointment due to my Chevy Volt's High Voltage battery charging only to 65% capacity despite indicating a full charge. Subsequently, on February 11th,...

While driving approximately 65 MPH on an interstate highway, the vehicle's check engine light illuminated. Very shortly after, the dashboard screen displayed the message "propulsion power reduced," and the internal combustion engine turned on. The vehicle's power was significantly reduced, almost causing an accident when another car started merging without checking their blind spot, forcing me into the left lane in front of a third vehicle that had to brake sharply to allow me to accelerate to keep up with traffic in that lane. Upon scanning the vehicle with an OBDII reader, codes P1E00, P1F06, U2603, U2604, U2605, U2606, U2617, and U2618 were present. Together, these codes indicate an issue with the Battery Energy Control Module (BECM). The vehicle is currently at a Chevrolet dealer, awaiting replacement of the BECM under the applicable warranty extension.

I got a warning from my car a little over a week ago (around 6/1, unsure of exact date) that I needed to service the battery charging system, but then the check engine indicator light shut off and so did the warning light. The hybrid battery took a charge with no issues after that. Then, I left work the evening of 6/9 and drove home. On my way home, the check engine light came back on, followed by warnings that I needed to shift to park. Before I could pull over, my car stopped moving. Cars had to stop abruptly behind me and navigate around me into incoming traffic. I shifted to park, then tried to turn my car off and on again. I tried to switch between the gas engine and the battery, I tried to move my vehicle in any way. I couldn't get it into neutral to...

Unknown My car has been accelerating and decelerating on it’s own while I’m driving.I got it checked with Fix Finder and states that my EGR Valve and ABS System failed. I brought it to a mechanic for a repair and I was told that the valve was unplugged so they plugged it back in and cleaned it , and said that everything was fine it said it might also be the cause of the failed ABS System but everything looks fine. After I got it fixed, it’s doing the same again and it’s worse this time. The car is accelerating on it’s own faster than what it did but the dashboard is saying 0mph. I was driving in the highway when it happened and it’s scary so I had to pull over.

I am submitting this complaint regarding a recurring and potentially hazardous issue in my Chevrolet Volt 2017.The vehicle frequently displays a “Shift to Park” warning message even when the gear shifter is correctly in the Park position. This malfunction prevents the car from shutting off properly, posing both safety and operational concerns. This issue is widely reported among Chevrolet Volt owners, and General Motors has acknowledged it in Technical Service Bulletin (TSB 19-NA-206). Despite this, no formal recall has been issued to ensure a permanent solution for affected drivers. My Volt currently has 138000miles, and although it is outside of the Voltec Warranty period, this is clearly a manufacturer defect—not a result of normal wear and tear. The problem affects the safe operation of the vehicle and may lead to battery drain, inability to power down the car, and driver confusion. I strongly urge the National Highway Traffic Safety Administration...

On December 2023 the vehicle lost power and lost control while driving speed limit 55 Mph followed by check engine light associated codes due to known issue with BCEM controller failing. June 2024 Vehicle experienced the same issue with duplicate check engine codes associated with prior issue. Dealer states the vehicle has a bad battery pack and has been there for over 8 months. Vehicle has a BECM warranty due to a law suite filed and also has a battery pack warranty from GM that was extended for 150,000 miles or 10 years.

The EGR valve failed. This caused the vehicle to have insufficient propulsion while driving. The dealer has confirmed the EGR valve is the problem. The vehicle is at the dealership. The check engine light came on. The dealer is now stating the replacement EGR valve is a $4000 part because GM stopped making the part when they discontinued the Volt. An EGR valve should cost $250-$400 not $4000. The current trade-in value of my vehicle is only $7000. I cannot get my vehicle fixed due to the cost and the vehicle is too dangerous to drive due to the power loss issues.

This car has a failed EGR valve which first became evident in March of 2024. There are no parts available, this in an emissions issue but the failure causes blown fuses which can cause the car to completely stop running which is a safety issue. Reduced propulsion is a symptom which is dangerous and this has been confirmed by three Chevy dealerships. I have had the EGR valve cleaned to the tune of $1200, have a deposit on a new valve which doesn't seem to exist for $850. There were no other messages before the failure. I am driving the car with the EGR valve disconnected, mostly on the battery power but no end is in sight to this problem.

I had the BECM fail as part of many 2017 volts with this issue at around 40K miles. This failure has caused multiple near accidents with immediately losing power at highway speeds. The last time this happened (after the BECM was replaced) was a couple of weeks ago. They said the reason for the failure was a programming issue, and they have updated it. It is flabbergasting to me that a programming issue can result in such a dangerous result. The car reduced propulsion on the highway and got stuck on the offramp while trying to pull over on the busy highway. Not only were we left stranded on the highway with me being 8 and a half months pregnant, but my husband almost got into an accident twice while trying to make it over safely. Chevy needs to be accountable for these significant failures that seem to continuously happen...

On [XXX] while traveling at highway speed my Chevrolet volt abruptly lost propulsion and an alert was displayed to pull over and turn car off. I was on [XXX] in California a 4 lane highway forced to cross 3 lanes of traffic at an exceptionally slow speed in heavy traffic. It is a miracle a crash did not occur. Fortunately other drivers were aware and able to stop or quickly change lanes. AAA towed directly to Stewart Chevrolet in Colma Ca. It was diagnosed and I was advised it is under warranty HOWEVER parts are on back order. Today [XXX] ~ the car still has not been repaired and I have been advised parts will not ship until September 2024. This is both dangerous and unacceptable.

I am writing to report a series of safety concerns regarding my 2017 Chevy Volt, which have persisted despite multiple attempts to address them with the dealership. These issues pose significant risks to my safety and that of others on the road. On January 18th, 2024, I brought my vehicle to the Provo Utah Chevrolet dealer after experiencing reduced propulsion power while driving on the highway, coupled with the illumination of the check engine light. The mechanic performed a quick inspection and used a GM scan tool to diagnose the issue, revealing the code P1E00 for the Hybrid Powertrain Control Module 2, which was cleared without a thorough investigation.

While we were driving on the freeway, we saw a check engine light and “propulsion power is reduced” message. The car began driving very roughly and we had to slow down. We had this happen once before where the car engine stopped working entirely while driving at city speeds after seeing this error earlier in the summer, so we pulled over as soon as we could. We were traveling in a remote area at the time, just before the holidays, and it was fairly cold out. The car dealer inspected the car and told us it was unsafe to drive, that we could not take it back until it was fixed, and that it was an EGR valve problem. We previously had this fixed under warranty as well for similar behavior, and the car is barely five years old with very few miles on it. It’s our only car and...

The contact owns a 2017 Chevrolet Volt. The contact stated that while driving approximately 65 MPH, the vehicle suddenly lost power and decelerated to 35 MPH. During the failure, the message "Reduced Power" was displayed. After turning off and restarting the vehicle, the failure remained, and the vehicle was driven to the residence at a reduced speed. The cause of the failure was not yet determined. The manufacturer and local dealer were contacted. The failure mileage was 26,000.

On 3/11/2023, I was heading home when my vehicle lost power in the middle of the freeway. Luckily, I was able to safely pull over to the side of the freeway. Since this is a plug-in hybrid, there are two gauges showing how much electric and gas is in the car. When I checked, both showed were empty; however, although I knew that I did not have much electricity in the battery, I had nearly a full tank of gas. The vehicle should have had automatically switched over to the gas but did not. After a few minutes of leaving the car off, I was able to restart the vehicle in gas mode and drive home safely. I brought in the vehicle to my local Chevy dealership to have it diagnosed. It was determine that the computer had registerd multiple faults p0030, 31, 54, 135, 403, 405, 443, 458 and...

This vehicle has a very dangerous malfunction. There was no power when I tried to move out of the way of an out-of-control semi truck while driving on the highway by pressing the pedal. I made every effort to maneuver because I was terrified. But because of the power outage, I could have died. This is really worrying, and I hope you can address the issue raised by Chevy so that someone else might be spared and so that future generations of electric cars are constructed to a standard that includes safety. Thank you.

While driving after the electric battery is used and switches over to gas, I have been getting the check engine, ABS, steering, parking, and brake lights. I have lost power steering, lost the speedometer, lost fuel range, lost stabilitrak, it has randomly turned on the emergency brake while all these other things are happening, It also has said “shift to park”, propulsion power reduced. I have taken it to the dealer and they read some of the codes but say they can’t find anything wrong and they need to be able to reproduce the problem to find it. I lost all propulsion and pulled over and turned it off and it stopped with a “clunk.” Then I turn it back on and just the check engine light is on. I’m very afraid to drive it but with the lack of vehicles available to buy and the dealer not knowing how...

After the battery runs out, the engine loses propulsion and fails to run on gas. The car completely stalls in the middle of traffic. The speed drops from 70+ mph to 0. Extremely dangerous to myself and others. The issue suddenly appeared at the end of December 2022 during a long drive. The engine check light remains on and a warning re: reduced propulsion power is displayed every time the car is turned on. Dealer is unable to fix the issue because they already have multiple cars with the same issue waiting for weeks to be repaired. Recently filed class action law suit suggests that this problem is caused by defective BCEM unit.

When shift-to-park the vehicle says the cars is not in park and will not turn off.

THE CRUISE CONTROL DOES NOT WORK EVERY SO OFTEN. IT SEEMS TO HAPPEN WHEN I USE A LOT OF THE STEERING CONTROL TO INCREASE AND DECREASE THE SPEED. IT'S I TOOK IT TO THE DEALERSHIP 2 TIMES AND THEY CAN'T FIND THE PROBLEM. I DON'T HAVE SPECIFIC DATES WHEN THIS HAPPENED BUT IT HAPPENS ENOUGH. OTHER THINGS THAT HAPPENS ARE 1) THE VOLT HAS A CHARGE SETTING THAT OPTIMIZE TO START CHARGE DELAY DEPENDING ON WHEN YOU SCHEDULE WHEN YOU PLAN TO LEAVE SO THE CAR WILL NOT BE LEFT FULLY CHARGE FOR A LONG TIME. HOWEVER, THE ESTIMATED CHARGE TIME IS COMPLETELY OFF NOW. IT SEEMS TO THINK IT WILL TAKE 12 MORE HOURS TO CHARGE. THEREFORE, THE CAR WOULD START CHARGING A FEW HOURS EARLIER THAN IT SHOULD. 2) THE AUDIO SYSTEM CONNECTED TO THE SMARTPHONE IS VERY BUGGY. SOMETIMES THE DISPLAY SHOWS MUSIC IS PLAYING BUT NO...

WE OWN TWO 2017 CHEVY VOLTS. BOTH HAVE TWO ISSUES: 1) OFTEN CRUISE CONTROL DOES ALWAYS STAY ENGAGED DUE TO BRAKE PEDAL SLIPPING TO A VERY SLIGHT DEPRESSED POSITION. 2) SHIFT-TO-PARK- CARS WILL NOT PROPERLY GO INTO PARK SOMETIMES AND THUS CANNOT BE TURNED OFF. THESE TWO ISSUES ARE CLEARLY MANUFACTURER DEFECTS AS BOTH CARS WERE BOUGHT NEW AND WITHIN A MONTH OF EACH OTHER. I WILL ENTER THIS FOR MY OTHER VIN NUMBER AS WELL. THESE HAVE BEEN ONGOING ISSUES THAT WE ARE HAVING TO SPEND MONEY TO CORRECT AND THERE ARE MANY REPORTS OF THESE BEING ISSUES, YET THERE IS NO RECALL. WE PURCHASED BOTH CARS BRAND NEW WITHIN A MONTH OF EACH OTHER. BOTH ISSUES HAVE BEEN ONGOING AND HAVE OCCURED MORE THAN ONCE.

MY 2017 CHEVY VOLT HAS AN ADAPTIVE CRUISE CONTROL PROBLEM . IT WILL ONLY WORK WHEN IT WANTS TO BUT WHAT MAKE IT SO DANGEROUS IS THAT IF YOU GET IT TO ENGAGE IT WILL RANDOMLY AND WITHOUT ANY WARNING DISENGAGE ITSELF. IF YOU ARE USING THE 2017 VOLT IN THE LOW GEAR MODE AND THIS HAPPENS THE CAR WILL RAPIDLY DECELERATE WHICH IS VERY DANGEROUS AND HAS ALMOST CAUSE THE PEOPLE BEHIND ME TO RUN INTO ME. I HAVE TRIED TO GET THIS FIXED SEVERAL TIMES BUT IT SEEMS NOBODY KNOWS WHAT TO DO WITH IT AND THEY WILL TRY BUT IT JUST GOES RIGHT BACK TO DOING IT AGAIN.

WHILE DRIVING ON CITY STREETS AND HIGHWAYS, THE ADAPTIVE CRUISE CONTROL WILL NOT ENGAGE 25% OF THE TIME AND WILL DISENGAGE WITHOUT NOTICE. "ADAPTIVE CRUISE CONTROL WILL APPEAR IN DIC. HOWEVER, THIS CREATES A SAFETY HAZARD AS YOU NEVER KNOW IF THE CAR WILL AUTOMATICALLY SLOW DOWN. I HAVE FILED CASE # 9-5379585813 WITH CHEVROLET AND BEEN TO FOUR DEALERS AND THEY REFUSE TO FIX THE PROBLEM. THEY NO LONGER RETURN MY CALLS. I AM AFRAID TO USE THE CRUISE CONTROL.

FAULTY FRONT PROXIMITY SENSOR OR CAMERA RESULTING IN FALSE POSITIVES OF OBJECT IN FRONT OF THE CAR. FALSE WARNING LIGHTS AND WARNING SOUNDS AS IF AN OBJECT IS IN FRONT OF THE CAR WHEN NO OBJECT IS IN SIGHT. USUALLY DURING THE RAIN BUT OCCASIONALLY NOT. OCCURS WHEN THE VEHICLE IS TRAVELING LESS THAN 6MPH. HAPPENS AROUND 75% OF THE TIME DURING THE RAIN AND ABOUT 5% OF THE TIME DURING DRY WEATHER.

DRIVING UP THE FREEWAY AT A NORMAL SPEED, MY VOLT BEGAN TO ACCELERATE WITHOUT WARNING AND AFTER APPLYING THE BRAKES AGAIN BEGAN TO ACCELERATE INVOLUNTARILY. AFTER I MANAGED TO PULL TO THE SIDE OF THE ROAD BY APPLYING THE BRAKES HARD, SMOKE CAME OUT OF THE HOOD. I CALLED A TOW TRUCK AND HE HAD TO JUMP THE CAR TO START IT AGAIN.

ADAPTIVE CRUISE CONTROL UNAVAILABLE RANDOMLY OCCURS WHILE DRIVING USING ADAPTIVE CRUISE CONTROL. PRESENTS A LARGE DANGER OF HITTING OTHER VEHICLES IF THE ADAPTIVE CRUISE CONTROL IS USED TO COME TO A COMPLETE STOP AS IT WILL RANDOMLY DISENGAGE WHILE COMING TO A STOP. CRUISE CONTROL ONLY WORKS 4/10 TIMES ATTEMPTED AND WAS "FIXED" BY THE DEALER WITH LESS THAN 500 MILES ON THE ODOMETER. HOWEVER THE PROBLEM RECURRED WITHIN A DAY. LOOKED IT UP IN FORUMS AND IT IS NOT AN UNCOMMON PROBLEM. HOLDING FOOT UNDER THE BRAKE PEDAL ALLOWS CRUISE CONTROL TO WORK BUT IS MORE DANGEROUS THAN RANDOMLY CUTTING OFF. NO ONE IN VOLT FORUM HAS GOTTEN A COMPLETE FIX TO DATE. WHEN THEY DO I WILL BE GETTING MINE REPAIRED ARMED WITH THE CORRECT INFORMATION. BUT IT IS DANGEROUS.

LIKE OTHERS, INCLUDING THE INCIDENT IN RANCHO CUCOMONGA, CA ON THE SAME DAY, APRIL 25TH, I WAS DRIVING ON THE HIGHWAY AT HIGH SPEED. I WAS IN THE CARPOOL LANE ON THE 210 FREEWAY. I THINK I ALSO WAS TOLD TO PUT THE CAR IN PARK. I LOST THE ABILITY TO ACCELERATE ON AT A VERY DANGEROUS TIME, WHILE I WAS THE FURTHEST TO THE LEFT IN THE LATE AFTERNOON. MIRACULOUSLY, THERE WAS ONLY 1 CAR QUITE FAR BEHIND ME. SO, AFTER DECELERATION WAS FORCED UPON MY CAR, I BEGAN TO STEER THE CAR TO THE RIGHT THROUGH 5 LANES - ONE OF THE WIDEST PARTS OF THE HIGHWAY AT THAT POINT. HERE IS WHAT I NOW THINK. I HAVE BEEN THROUGH LOSS OF POWER IN MY 2014 VOLT. I HAD ACCIDENTALLY TURNED IT OFF WHILE BEING ON THE HIGHWAY. THEY FIXED THAT DESIGN FLAW IN THIS 2017 MODEL. I...

I PURCHASED A NEW 2017 CHEVROLET VOLT EQUIPMENT WITH AUTOMATIC PARKING ASSIST. ON NOVEMBER 1, 2017, I WAS DRIVING ON BATH STREET IN SANTA BARBARA. I DECIDED TO PARK ON BATH AT PUEBLO STREET. THE FIRST TIME, I ENGAGED THE APA FEATURE TO ASSIST WITH PARALLEL PARKING, I FOLLOWED THE INSTRUCTIONS ON THE DASHBOARD. AFTER COMING TO A COMPLETE STOP, I FOLLOWED THE DIRECTION TO SHIFT THE CAR INTO REVERSE. THE MOMENT I COMPLETED THE SHIFT AND I LIFTED BY FOOT FROM THE BRAKE, THE VEHICLE ACCELERATED UNEXPECTEDLY IN REVERSE AT A HIGH RATE OF SPEED. THE STEERING WHEEL TURNED TO THE RIGHT, AND THE CAR CONTINUED TO ACCELERATE OUT OF CONTROL UNTIL IT HAD JUMPED THE CURB AND SIDESWIPED A TELEPHONE POLE. I HAD THE VEHICLE TOWED TO A CHEVY DEALER AND FILED A CLAIM FOR PRODUCT DEFECT WITH GENERAL MOTORS. GENERAL MOTORS HAS SUBSEQUENTLY DECLINED THE CLAIM.

WE BOUGHT A NEW 2017 CHEVY VOLT AT THE END OF DECEMBER 2016 AND HAD OUR FIRST ISSUE IN EARLY FEBRUARY 2017. WHAT HAPPENED THAT FIRST TIME WAS ON (2/3/2017) WHILE DRIVING THROUGH TRAFFIC THE CAR WITHOUT WARNING TURNED OFF THE ELECTRIC WHEEL MOTORS AND WOULD NOT ALLOW US TO POWER THE CAR PROPERLY TO GET THE CAR TO THE BERM. WE WERE NEARLY WERE HIT TWICE WHILE TRYING TO STEER THE CAR OFF OF THE INTERSTATE HIGHWAY AS IT DECELERATED. THE CAR WAS COMPLETELY DISABLED AN NEEDED TOWED BACK TO THE DEALERSHIP. AFTER THE DEALERSHIP HAD THE CAR FOR A WEEK THEY RETURNED IT WITH THE EXPLANATION THAT THE CAR NEEDED TO DO SOFTWARE UPDATES AND THEY WERE TOO LARGE TO DO OVER THE CAR'S SATELLITE SYSTEM ' BUT THEY NEVER GAVE US ANY INDICATION OF HOW WE WOULD HAVE BEEN INFORMED OF THE NEED FOR SUCH AN UPDATE....
