“Odometer Fraud. The contact purchased a 2012 Honda Civic. The contact stated that before attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private dealer sale. At the time of purchase, the vehicle mileage was 116,000. Through a Carfax report, it was discovered that the mileage was 159,000.”
“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…”
“Odometer Fraud. The contact purchased a 2012 Honda Civic. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 119,560, and the contact stated she looked at the title and took the vehicle to a mechanic to verify and noticed that the mileage was 193,099.”
“Odometer Fraud. The contact purchased a 2012 Honda Civic. The contact stated that while attempting to repair the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was an independent dealer sale. At the time of purchase, the vehicle mileage was 71,00 and at the time of replacing the instrument panel, it was discovered that the mileage was 190,000.”
“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.”
“Owns a 2012 HONDA Civic Hybrid. While driving ~30MPH, the IMA/braking/engine/charging/ABS lights illuminated. The car still driving but the hybrid system fails. Also, when starting the engine it switches to using the starter instead of the EV motor. The 12V battery will not charge and die soon, which increases the risk of a stall on the road, thus leading to a crash. The vehicle was taken to a Honda Dealer which suggests a Model Power Inverter failure. There is a Technical Service Bulletin: 20-030 (Warranty Extension: 2012-15 Civic Hybrid IMA Motor Power Inverter) related to the failing parts, however, the vehicle was not covered under the TSB. The vehicle was not prepared. The failure mileage was approximately 123,000 miles.”
