After the car has warmed up, a high pitched whistling sound (think dog whistle) emits upon rapid acceleration between 30 and 70 mph. Have worked with Honda service depts, engineers, and customer service since February (estimated date) to no resolution. Noise began around 41K miles and has continued since. It is a distraction making it difficult to concentrate when driving.

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.

I was driving on highway at approx 75mph when got message power failed, overheating and breaks failed. Accelerator / gas pedal stopped working. Could have been big accident if vehicle from behind hit the car.
