The fuel gauge and range indicator are faulty. I was doing long-distance highway driving during the holidays. At 1/4 tank, the range indicator said 110 miles until empty. As soon as the needle dipped a fraction below 1/4 tank (about 20 miles later) the range indicator dropped instantly to 40 miles left AND THEN DROPPED ONE MILE PER SECOND UNTIL IT REGISTERED ZERO. The needle also fell at the same rate until I was driving on the interstate with zero range and a gas gauge buried below empty. All of this occurred within one minute. I pulled into the nearest gas station and filled up with $12.71 gallons (it's an 18.5 gallon tank). So I actually had 5.79 gallons left (or $156.33 miles of range at 27mpg on the highway). Not being able to rely on the gas gauge/range indicator is a safety issue.

I was driving my 2024 CX90 PHEV when a warning about an electrical leakage in the hybrid system was detected. I brought it home and parked in my garage. I called the dealership and they told me to bring it in. When I started to leave, the car would not shift out of park and bricked up. A towing service had to drag it out of my garage. My concern is that there is no limp mode or any way to switch to the gasoline engine when this happened. Had there been a fire in the battery, I would not have been able to get it out of my garage, putting our house and children at risk. Also, had it locked up on a highway, an accident could easily happen. After the dealership dragged it off of the rollback, they couldn-??t even get the car to move. They told me that they would have to order special tools to be able to get the car to move. Along with the steering recall that worked for about a month, the steering rack had to be replaced, and the failure of the electrical system, I feel like this car is unsafe to drive. Thank you.

I was traveling at 40mph on August 14 when the engine stopped running suddenly and without warning. I lost all power. I tried pressing the gas pedal and the engine shuddered and sputtered with the speed ranging from 0 mph to about 18mph with no steady duration longer than a second or two. At the same time an engine icon appeared and a message displayed reading engine malfunction. I safely exited the travel lane despite having very little power. I waited 10 seconds and restarted the car and everything worked fine. I called the dealer explained the incident and to made arrangements to have the vehicle serviced. The appointment was for Friday. When I asked whether I should continue driving the car. I was told that so long as the engine icon was not flashing the car was ok to drive. The next day I started the car and did not see any warning message or engine icon. I thought all was ok so I cancelled the appointment. A second incident occurred later in the morning. I called the dealer again and was told to bring the car in that afternoon, Thursday. On the way over to drop off the car a third incident occurred with the same characteristics as the first two. Each time waiting 5 to 10 seconds restored power to the car. One week later the car was returned to me with the diagnosis of low fuel pump pressure problem. I am wary of driving this car on any trip especially on a speed highway for fear this situation will occur when I am driving at 70mph. I appreciate your taking the time to read this description of a very scary and unnerving situation that no one should face.

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.
