NHTSA Complaint #11525650 — 2013 HONDA INSIGHT

I experienced "rough running" of my 2013 Honda Insight just prior to August of 2021. Initial work on the vehicle helped, but repairs became increasingly expensive and extensive. EX: A simple oil change on about 8/2/2021 (mileage at 64,545). At about mileage 68,370 the vehicle failed again (showing check engine light / stalling); repair shop found a misfire on cylinder #4, and all 8 of the spark plugs were replaced.  Then on/about Nov./2022 (mileage at 71,988), the vehicle was running rough again (with check engine light on) and the repair shop found a miss in cylinder #4 again, and then replaced cylinder #4  spark plugs and coils. On/about Feb./2023, the vehicle had more problems (running rough) and then the repair shop found a misfire on #4 again (spark plug was replaced.) On/about 5/18/2023, I took my vehicle in for a routine oil change. About two days later, on/about 5/20/2023, I (along with my girlfriend) drove on the freeway for a long trip. We had only been on the freeway for a few miles when the engine died. I had accelerated to 75 m.p.h. on a slight upgrade and was in the process of setting the cruise control when the engine revved up to 4,000 r.p.m.'s (as if it was climbing a steep hill); several warning lights showed up on the dashboard.  I immediately disengaged the cruise control while in the left lane and (thankfully due to no vehicles being near us) was able to get the vehicle off to the right edge of the freeway. The vehicle had no power. I called a tow truck and the driver attempted to drive the Honda Insight onto his ramp (with thick smoke billowing out of the exhaust pipe) but it was only able to go half the car length up the ramp. At first, I was told it needed 2 spark plugs and was fixed. I reminded them that all 8 had recently been replaced; they then said no compression on #2 / that engine was dead. Took it to Honda; diagnosed it as the oil consumption issue. Check lights are for systems: emmission, brake, VSA, w/ various other lights on dash.
