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.

On my way to drop kid to school all of a sudden the car gave up power and shuddered with engine malfunction and I-drive malfunction warning. Check engine light came on. This is risky because another vehicle could have smashed into us if on highway or high speed. Research shows that a whole lot of people have this identical issue.

- Litchfield Park, AZ, USA

Stopped at a red light on a busy 2-lane road. I-stop function turned the engine off. When the light turned green, releasing the brake caused a "Hybrid Battery Malfunction" error and the engine failed to start. We put the transmission in park and attempted to turn off and turn on the car with the push to start button. When we attempted to start the car with the push to start button, the car would not start. We were unable to shift into neutral to move the car out of the busy 2-lane highway and were blocking traffic for about an hour. The first tow truck to arrive was unable to move the car onto the flat-bed because the transmission was stuck in park and would not go into neutral so another tow truck was dispatched with a dolly. Our safety was at risk because we were stuck in an immobile car in busy highway traffic. A police officer arrived to help direct traffic around our disabled car. The vehicle is currently at the dealership and has not been inspected as of the time of this report.

Mazda CX 90 PHEV. When charging on 110 standard outlet or 240v dedicated breaker - Chargepoint charger, the car onboard charger/inverter backfeeds a loud buzzing / humming back through the electrical wire to the electrical panel. It also causes a buzzing/humming in other appliances and causes led lights in the house to flicker. This is with a 100amp breaker panel and a new upgraded 200amp breaker panel. May cause electrical issues up to electrical fire in other areas of the home. Scheduled diagnostic test in vehicle 10/1/24, but other owners report same issue on Mazda CX 90 online forums.

On July 15, 2024 this vehicle at 50 mph on cruise control suddenly flashed white warning words indicating problems with the cruise control and immediately thereafter started flashing -??hybrid malfunction-?? and to return to service dealer. At the time of the hybrid malfunction warning which was right after the quick cruise control warning, the engine operation, specifically the gas pedal no longer delivered power to vehicle, either electric or gas. Additional warning was to pull off to the side and stop and turn off vehicle. This occurred and vehicle was pulled to the side put into park and turned off. Waited approximately 3 to 5 minutes and restarted the engine which started in gas with no electric although there was electrical charge on the battery. Was able to continue to our final destination approximately 15 minutes later and no more than 10 miles driven. Hybrid malfunction was still visible on the dash to include the warning stating that vehicle needed to go to the service department. Approximately an hour later, vehicle was turned on again with the same warning about the hybrid malfunction, however, engine started in electric. Drove vehicle to dealership and stated what happened. Dealership the next day stated that this was a phantom code known by Mazda, but no problems associated with the code. Vehicle picked up per service advisors request two days later. Mazda dealership stated that headquarters had eyes on this particular vehicle. A day later after the pick up Mazda dealership requested vehicle be brought back for a -??DC box-?? repair. Dealership stated this process would take a week or thereabouts to replace this component. Vehicle currently in dealership service.

Driving up snowy pass on I-90 approaching the top of Snoqualmie Pass. Vehicle stalled and warning lights flashed critical warning and loss of power. The vehicle stopped in the middle of the highway and would not start or go into drive. After a few minutes, because of speeding and adverse conditions, another driver collided with my vehicle from behind. Another following vehicle lost control and ran off the road. Nobody was injured. Mazda has not provided any information to what happened with the vehicle. We added about 12k miles in the 5 months of driving it, so we had lots of testing with it, and never ran into this serious of an issue with this or any other vehicle.

While connected to a level 2 charger, overheating caused both the charger and charging port of the vehicle to melt together such that it was very difficult to disconnect, and both were then unusable -?" needing replacement. (photos attached) We feel that there should be some safeguard in the vehicle to prevent this situation as it is a fire hazard. There were no warning lights, sounds, nor signals from the vehicle to warn of the problem. We were present when this occurred, so we could disconnect before a potential fire may have occurred. When we called for service, we had to wait two weeks for an appointment, and then were told that the car was not safe to drive until repaired. This was not considered a warranty item even though the car had fewer than 2800 miles and only owned by us for fewer than 7 months. We were charged $5000 for the charging port and cable assembly and $800 labor. (Copies of service receipts attached.) We contacted Mazda regarding our concern and were given Case #00182286. We received a reply by phone telling us that Mazda bears no responsibility for this (they feel ii was the fault of the charger) and that it is an insurance matter. In fact, auto insurance does NOT cover this. Our concern is that it very well may be a safety issue as people usually charge in their garages or near other cars and buildings in public. In either situation, a fire could be a serious hazard for many people.

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.

There has been two dangerous failures both occurring in an intersection. First instance was in December of 2023 whey the fuel pump failed while turning in an intersection. The second incident was a hybrid battery malfunction, rendering my vehicle unusable in the middle of an intersection again. This was 03/2023

On [XXX], I was driving on [XXX] near Pasadena at normal speed of traffic when suddenly an error message -??Hybrid System Malfunction-?? appeared on the dash board along with check engine light, and the car began to stall slowing down to nearly full stop almost immediately. When I pressed gas pedal, it would not accelerate. Because I was in the far right lane, I had just about enough time to pull over onto the shoulder before the car stopped completely. The car was in EV mode (using all electric power) when this incident occurred with 20 miles of electric range still left. I was lucky that no cars were right behind me as the traffic was moving about 60 mph or my car could have been rear-ended when it came to such an abrupt stop. I put the car in park and turned off the engine, then turned it back on after a couple of minutes. The dashboard was flashing -??Hybrid System Malfunction-?? and -??check engine-?? light was on but I was able to drive it because it had switched to gas power mode. I immediately drove the car to New Century Mazda in Alhambra where I purchased it on [XXX]. The Mazda app on my phone captured two Vehicle Issues Detected at the same time: Hybrid System Malfunction: There is a possibility of restricted power output-?? and -??i-ACTIVSENSE malfunction.-?? The Hybrid System Malfunction was the most serious and frightening of a series of malfunctions that my car experienced since it was purchased two months ago. On [XXX] (4 days after purchase) the car displayed -??Approaching Vehicle Audible System (AVIS) Malfunction, -?? on [XXX], a -??Brake!-??light came on when we started the car after it had been parked, which disabled the steering wheel and the gear shift preventing us from driving (problem resolved by turning the car on and off several times). On [XXX], another vehicle issue was detected: -??Air bag system and seatbelt pre-tensioner system malfunction.-?? Car was fully inspected by Mazda dealer in mid-January.

I have a recall open on my CX-90, took the car to the dealership and they informed me that the car was fixed, the recall is 6223J, but it is still happening it happened a day after the reprogramming, it is not fixed and I'm not sure if the fix is good I have a full video about it, I was able to record date and time when it was recorded, I did a gif to be able to upload it to the website

The major issue that happened to our newly purchased CX 90 last February 3 with more than 500 miles on it started around 5:30 pm of February 8, while my wife is driving this vehicle with my daughter, all of a sudden the car stopped at the middle of the road with warning signs popping up in the dash screen like I-active sense malfunction, hybrid battery malfunction, engine malfunction light on, and on top of these, critical vehicle malfunction. The car won't start and disabled. Also, the vehicle cannot switch to neutral gear to push/pull the vehicle to the side that made the vehicle blocking the roadway until the tow truck came in. My wife and daughter's life was put in danger when this vehicle suddenly stopped in the middle of the road with cars passing by on both ways. I also found out based on the NHTSA vehicle safety, Mazda recall website, carfax and Kelly blue book, that this particular vehicle with its VIN has a SAFETY RECALL due to its steering issue that may increase risk for crash. This was not disclosed to us when we are on the process purchasing this vehicle and they did state inspection and passed it that made we doubt how did it happened.. The vehicle is now with the dealership repair shop and the last update I receive was the technician is still checking on it.
