1. Gear Shift Issue in EV Mode: The transition from 1st to 2nd gear is not shifting properly in EV mode. At times, the gear jerks during critical situations, which compromises control. 2. Power Output on Highway: While driving on the highway, there are instances where there is no power output when flooring the accelerator to overtake. 3. Engine Malfunction Light: The engine malfunction light has come on and off three times. 4. Radar Malfunction: The radar system is intermittently not working or working improperly. The radar malfunction light also came on and off once (i-ACTIVSENSE system malfunction). The last safety recall was completed a few weeks ago, but the issues are still ongoing. Since then, I have visited the Mazda dealership twice, but they let me go, dismissing my claims and saying they couldn-??t duplicate the problems. I have a case with Mazda corporation. Nothing done yet (Case Number: [XXX]). The name of the Representative is Candy. I would appreciate it if you could investigate these issues at the earliest convenience. Thank you for your attention to these matters. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I-??ve only owned this brand new vehicle for just two months. Had I known these issues, I would not have purchased the CX90! Having issue with I-stop causing vehicle to stop whenever and now the dash display just popped up yesterday 12/09/24 regarding -??Headlight Malfunction contact dealership-??. I contacted the dealership yesterday and was going to be charged for a diagnostic test on a two month old vehicle, I don-??t think customers should have to pay for a diagnostic test on a -??brand new vehicle-?? and was also advised, Mazda is aware and working on issue (headlight malfunction has been complained about since 2023) but no recall on headlight malfunction, test! As well as now, there are two campaign #7024 J and #7124 J But at the present time service department is waiting on -??when-?? the recall and headlight issue can be serviced! I-??m confused why owning a brand new vehicle and being told of issues and experiencing issue along with recalls and not being able to get them fixed is asinine! What customer wants to pay lots of money on a vehicle to risk injury or damage due to manufacturer dragging their feet. I would appreciate assistance in these issues! Thank you

While driving (less than 2000 miles on the OD) in our 2024 cx90 SE the vehicle started to shift out of timing and everything shut off at once. The vehicle lost all power and all parts shut down. The vehicle would start back up and power steering went out. Our driving speed was at 30mph so it was extremely scary during rush hour traffic. We had to have it towed to the dealership, we're not sure what the issue will be.

The contact owned a 2024 Mazda CX-90. The contact stated while driving 40 MPH, the engine seized. The contact stated that the failure occurred while the contact was driving at night on a busy dark road. The Police was contacted for assistance. The contact stated that it took two days for the vehicle to be towed from the location because the vehicle was missing a tow tool. The vehicle was towed to the dealer where the vehicle was diagnosed with engine failure. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The contact no longer owns the vehicle, after agreeing to a buyback. The failure mileage was approximately 28,100.

Vehicle present engine hesitation. In acceleration the engine losses power, noticeable delay and jerk when accelerating from a stop. Also if you have to make a suddenly speed reduction, you see that the vehicle still accelerating. First time the dealership did a technician service bulletin to fixed the problem, but for the second time with exactly the same problem they said that is normal. That-??s a safety issue and Mazda is ignoring the concern.

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.

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.

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!!
