Hello, I turned my car on and saw the engine emissions system warning, which I’ve never seen before. I thought the cold front or sudden temperature change in my city had something to do with it & it would go away because my car is well maintained(all services done at Honda dealership). I was driving on the freeway about 75 mph and all of a sudden my car stops accelerating. I floored the gas pedal but it was only going about 30 mph(felt weak or like it was operating on battery only) this is when the “engine cooling system problem” and “engine temperature too hot” warnings started flashing. The car behind me almost hit me, other cars were passing & honking at me, I was holding up traffic so I got in the emergency lane. While in the emergency lane I had to turn my car on an off about 6 times for it to work normally for about 5/10 minutes before it would start stalling or the acceleration would stop working(this would happen when the coolant warning started flashing) until I got home. I was confused on why the car wasn’t accelerating like normal because I had more than half a gas tank left & my coolant has been replaced. The next day I turn on my car and it’s perfectly normal-no warnings. I took it to the Honda services and showed them the video I took of the warnings because I was scared and felt unsafe driving it, but they told me to bring it back when the warning lights turn back on the dashboard. It was Normal for about a week, then the warning lights popped back up and it would start stalling/not accelerate again. I constantly had to turn my car off and on driving to Honda services. They told me nothing is wrong with the coolant, they did a diagnostic test on it and said it’s the Computer module/electrical interference causing the warning lights/pumps not to not work. I believe it’s the hybrid propulsion system recall 15V602000, I have a 2015 Honda Accord Hybrid but my VIN is not recalled? Is there anyway to add my vin to the recall? Please and thank you.

I was driving on a highway at 70mph when signs suchs as "engine cooling system problem", "emissions system problem" started displaying on dashboard and speed was decreasing and I couldn't speed up. I pulled over to the shoulder and turned off the car and turned it back on and signs were gone. I drove home fine. I went to dealership and they stated nothing is wrong with the car.

I had purchased brand new accord hybrid 2015 in december 2015 and in january 2018 car battery is drained fully due to unknown reason. Last night , in -5f temperature my car broke on the road and I have seen worst in my life due to car issue on the road. I would appreciate , if you look into the quality of battery issue being placed in car from honda and various dealers as it sounds sketchy to me. Even if I drove 45k miles battery should last longer on newer car compare older cars. I would appreciate , if you can look into it more closely.

Vehicle stalled while driving on a highway with power system failure warning. I could not accelerate the car. I had to take the exit since I was luckily in the right lane and close to the exit. Car was running on battery only at around 30 MPH. I pulled out in the parking lot, turned off power and turned back on and was able to reach home. I took the car to the dealer, they could not diagnose the issue right away and asked me to leave the cardie to drivability issue. They called us back after 2 days and told us that they updated the software. I do not feel safe driving this car. Please take necessary action immediately.

Problem usually occurs during the day and when the weather is hot. Power system problem display comes on and engine service light as well. Turning the car off and on helps but the engine light stays on for another 24 hrs or so before turning off. The car felt like it lose gas engine power and operates electric only. I was going 65mph on the freeway, and when I try to step on the gas peddel, I can maintain that speed as long as the battery had enough power but the gas engine will not kick on. It was not a pleasant experience as I was driving on the left lane and was quickly trying to move over to the right on a freeway without shoulders. Luckily I was able to make it to the next nearest exit, half a mile away. Had the error msg appear 4 times in 2 weeks. Took the car to the dealer 3 times within that time frame. My first visit, they didnt see anything wrong, no dtc codes, no check engine light. Second visit, I told them about the software update I saw on this site. They applied patch tsb 15-057 hv cell voltage sensor (cvs) software update, took the car home, when to work later in the afternoon, and power system problem message came on again. Third visit, no dashboard lights stayed on once again, told them about how it was my 3rd visit in 2 weeks. Tech drove the car for 10 miles, power system problem pops up. Found dtcs codes finally. Code p108 - generator motor inverters, and code 0562 - generator motor control module system low voltage. Tech performed troubleshooting for p108c and reapplied patch, I guess it didnt go thru the first time? Drove it for another 10 miles and found no errors this time. It has been 5 days since my last visit and I have not had the issue since. Also to note, it has not been as hot here in the northeast the last few days. Highs in the 70s compare to 80s-90s when I began having this issue.
