“So according to Honda Service Bulletin 20-030, all honda civic 2012-2015 hybrids having IMA Motor Power Inverter (MPI) have to fixed. I have the SAME CAR, SAME MODEL, SAME YEAR AND SAME ERROR CODES AS THE SERVICE BULLETIN AND THIS IS SUCH A SERIOUS ELECTRICAL POWER INVERTER ISSUE. Yet HONDA IS denying to work on it, even though there is 15 years or 150,000 miles warranty for this specific issue and MY CAR HAS 95000 miles. Yet HONDA is trying to run away from fixing it by claiming the VIN number is not associating whereby MY CAR IS EXACT SAME AS THE MODEL, year and issue for the GIVEN SERVICE BULLETIN. This is complete absurd and consumer rights are being thrown away by Honda. I am very sure that my United States NHTSA, state consumer protection, federal trade commission, all are going to help me and make Honda pay for this. I have attached the service bulletin and here my error codes on the car: P1437 Motor Drive Module (MDM) Short Circuit POA78 Tmu-L Motor Power Inverter Module Internal Circuit Malfunction P15A5 Motor Current Sensor Circuit Malfunction Clear Confirmed & Pending Trouble Codes 2 Pending Trouble Codes POA78 Tmu-L Motor Power Inverter Module…”
“The contact's stepdaughter owns a 2012 Honda Civic Hybrid. The contact stated that while his stepdaughter was driving at approximately 40 MPH, the check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who informed the contact about Service Bulletin 20-030 Warranty Extension related to the IMA motor power inverter (MPI) and was referred to the dealer. The vehicle was taken to the local dealer, who diagnosed that the failure was due to the IMA Motor Power Inverter (MPI). The dealer informed him there was no recall or warranty coverage. The vehicle was not repaired. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 90,000.”
“The IMA inverter system keeps malfunctioning without any clear reasons, and the car is in drive mode, which makes the electric motor unresponsive. Additionally, the braking system also malfunctions, leading to a lack of control over the vehicle. I have tried to repair it multiple times, but to no avail. It keeps malfunctioning without any apparent reason.”
“I purchased this vehicle 6 months ago from a dealer. In the short time I have had the car, there have been multiple issues presented. Bluetooth has been malfunctioning (connects the disconnects), window regulator has had to be replaced three times now (window kept disconnecting from the track and would cause the window to go down sideways and get stuck), more recently the AC condenser went out (it was reported as the condenser has small pieces of metal inside preventing the freon to get into the system and cool the inside of the vehicle).”
“When starting from a stopped position, there is a squeal when letting out the clutch. I took it back to the dealership 3x and they couldn't duplicate it. Apparently it is a known issue as there are bulletins on it. It happens almost every time, especially on a slight incline.”
“So on 11/6/19 Silko Honda Raynham, MA worked on my car for recall {campaign recall 19-106 6bd00- 2012 civic cold emissions gas reduction) So ever since this update on my computer I had non stop tightening gas cap which has been replaced with dealer cap did not work, and when the gas cap light goes out then get check emissions light does this non stop between both lights throughout the day everyday, I've had every single thing fixed that says with the code I get from check engine light nothing works but it passes inspection all I can think of is computer update only thing makes since .Also had 3 smoke test to comes back no leaks. the code I get is this P0497,p145c it has 7 things to do to resolve code which are 1)reconnection of hoses 2)wiring replacement 3)vacuum 4)charcoal canister replacement 5)canister purge valve replacement 6)gas cap replacement 7)clearing of codes and retesting with scan tool to ensure the problem is fixed. IVE DONE ALL AND STILL HAPPENING!! VIN # [XXX] 2012 Honda civic LX Mileage is at -99,535 [XXX] Cell # [XXX] “”
