2018 Honda Clarity Plug-In Hybrid Fuel system Problems

“We leased a 2018 Honda clarity in december of 2017. Since then, the car has lost power several times (over 25 times). Attached are 2 separate video clips showing the car losing power. The car feels like the engine disengages and the revolutions go up, but the car slows down. I have been on the freeway going up a hill, when the engine lost power. We went from 65 MPH down to 20 MPH. I had to fully stop in the emergency lane and accelerate again to clear the issue. …”

“While driving on the interstate through the mountains, the car was able to keep up with traffic at the bottom of the mountain. However, as I approached the summit, no matter how far down I pushed the accelerator pedal, the car would not increase speed. With the pedal completely floored (past the hybrid system click point) the car would still not pickup speed, nor did it sound like the engine was even trying to rev higher. As I kept approaching the summit with the pedal floored, the car started to slowly lose speed. …”

“State of driving condition: the car was set in cruise at 70 MPH in hv mode (not charge mode). Ev range was 30 mile remaining, approximately 70% of battery remaining. The Honda clarity phev spontaneous excessive revving the engine while cruising at a constant speed on flat highway road then the car dropped speed by itself without any car in front. Once I notice the car does not have power to regain to set cruising speed, I turned cruising off, switched the car from hv to EV then the engine stop doing high revving. …”

“So my wife took the clarity on her regular commute for the first time since a bunch of recalls were performed on the car on friday. Along with a01 service, product updates 18-089, 90, 91 and 97 were performed on the car. She ran into a dangerous situation. I'll list the steps below. Has anyone else encountered this? I plan to report to NHTSA also. - she was driving normally on her way back home in econ mode at around 70 MPH or under. Prior to the updates the battery never used to go below 9 or 10% (last two bars). But today it went to no bars left. …”

“We leased our vehicle in november of 2018. From the test drive and going forward we noticed high engine idle during acceleration but was told the car needed to be charged.(we were never told of anything regarding loss of engine power or acceleration if the battery is low! False advertising!) as the days went by we noticed the issue getting worse and that the revving was actually the car losing power when driving in any condition or driving mode. While driving the car and the battery gets to two bars the car would loose power and will not go over 10 MPH. …”
