I was driving 65 mph and the hybrid system malfunction warning came up. Car dropped to 25mph - pressing the gas pedal would not increase the speed. Continued to coast with no acceleration until it came to a stop and shut off

4 weeks ago my wife was driving on a busy highway and lost propulsion. Hybrid System malfunction message. She was able to pull over before causing an accident and put the car in gas only mode. She never shut the car off and drove on to her destination. I met her and picked up the car and took it to the dealer. Car is new and has 5000 miles on it. Car has been at dealer for 4 weeks with no answers and several unanswered phone calls to customer service at Mazda Corporate. Been told that is is a software problem with no fix and no time frame of when there will be a fix. I do have a case number with Mazda. Today after threatening calls to invoke "Lemon Law" in my state Mazda has suddenly said that the car has a faulty inverter and that the part is available and will be replaced. My feeling is that they are just throwing parts at a problem. This car is unsafe and NHSTA should put pressure on Mazda to either resolve issue or buy back cars. The majority of the complaints listed here are the same. Please take action!!

Car suddenly, unexpectedly, and without warning lost power while driving putting us at risk for serious collision/injury with inability to drive the car and then gave "Hybrid System Malfunction" warning. This occurred AFTER performing the recall which was supposed to address this issue.

At 3200 miles the vehicle had a major powertrain malfunction causing the vehicle to throw multiple error codes - Hybrid System Malfunction; Charging System Malfunction; Electrical Leakage Detected. Was instructed to pull over to a safe area immediately. Was unclear how long car would continue to be drivable. Once car stopped it became completely immobile. Repeated restart attempts would not let vehicle start ICE engine or shift into gear. Had to be towed via dollies to nearest dealer for diagnosis and repair. Dealer found a failed PTC heater unit as source of problem and replaced it (Mazda part- KMV6-61-FHX). Vehicle is once again drivable, but the dealer has no idea what would cause the unit to fail and how to avoid future problems. Dealer has heard about this with many vehicles and repaired several similarly. We are fortunate to have found a safe place to pull off the road before powertrain shutdown, but if not we would have been stuck on the road with no ability to move the vehicle and occupants to safety. I hope NHTSA can investigate whether a recall of that part or the software that controls it is needed. NHTSA should also look into the failure mode of the vehicle to see if a different approach is safer and more appropriate.

I was driving on the freeway on the fast lane and the vehicle slowed from 65mph to zero in about 30 seconds and came to a complete stop. It happened so fast I couldn-??t change lanes to get to a safe spot. I was left stranded on the fast lane of the freeway with traffic coming right at me. Vehicle displayed a Hybrid system malfunction message.
