In May, we bought my nephew a 2017 Honda Civic for graduation. It has been one thing after another. Test drove great, drove 40 minutes home after purchase, great.

A few weeks later, drove an hour and half to give to him. Air stopped blowing cold air. Stopped. And got back in to start car, check engine light came on. Air worked again. First code at O’Reilys and Advance was P0340. Car cut off turning a parking lot. We ordered the camshaft position sensors and changed both the next day. Drove fine afterwards and no lights, no cutting off. Gave to nephew that evening - cut off on him driving home. Took to local mechanic, got P0714 code – CVT Fluid Temp Sensor Intermittent Failure. Mechanic recommended taking to Honda. On nephews ear home (less than 5 miles), car cut off and dash lights blinking D, check engine, etc. Towed to Honda Service Center.

▪ Honda got same code and recommended replacing Solenoid Wire Harness (valve body) and retest – agreed and approved

Honda also received code B1225 open in the incar temperature sensor circuit for AC.

unfortunately same issue happened a few days later - cut off and blinking dash D and check engine light came on. went back to Honda

Honda replaced transmission. $7000

next day, same issues - back to Honda

Honda said the issue was that one of theConnectors was Soft Set
✓ Honda corrected the soft set, found no further codes, but wanted to test drive more before releasing.

test drove- same issues

✓ Honda is now getting Code P0977 – Transmission Control Module, Shift Solenoid B Control Circuit High

replaced TCM - same issues.

how could this happen all in a matter of a few weeks? Could it be electrical? Certain wiring? Something else?
