2025 MAZDA CX-90 Complaints

The vehicle repeatedly displays warnings including “Acceleration Limited Due to Low Fuel and/or Battery Condition,” Hybrid System Malfunction, and Engine System warnings. These events result in reduced acceleration and loss of power while driving. The condition occurs despite normal fuel levels and routine driving conditions. The vehicle has been taken to the dealership multiple times. Each time, I am told no fault codes are present or the issue cannot be replicated. The warnings continue to recur and remain unresolved. This creates an unsafe driving condition due to unpredictable power limitation. This issue appears to be a known problem affecting Mazda CX-90 vehicles and may be related to hybrid system software or battery management. The vehicle was being driven on a city road (Lake Forrest and University dr in McKinney, TX). Turned right off of a shopping center exit toward Lake Forest Dr. The vehicle lost power all of a sudden and would not accelerate with traffic heading in my direction. The vehicle signaled to stop and place the gear into park. I was able to slowly change lanes and pull into the Chipotle parking lot at 5151 W. University Dr at 10:56 am. I called Mazda Roadside and they came to tow it to El Dorado Mazda dealership. This incident: Date: 01/10/26 Time: 10:56 am Temp: 45° / clear and sunny Previous Incident: 12/04/25 6 pm Parked - Idling at Prosper High School. I-stop and hybrid system malfunction warnings appeared Called El Dorado Mazda- advised it was not a safety issue and sometimes it just needed a software update or the battery was bad. They scheduled a service appt until 12/17/26 due to lack of loaner vehicles available. 12/08/25 / 12:05 pm Clear weather Inspected at El Dorado Mazda Could not be Duplicated. Battery OK Nothing came up on diagnostic machine. Cleared recall. Advised to return if it happened again. Reassured me it was safe to drive and I was not in danger. 12/16/25 Car started from park at home Approx 40-50° 9-10 am 1/10/26-

Premature tire tread wear on 2025 Mazda CX-90 PHEV equipped with OEM Falken tires. At 21,586 miles, an authorized Mazda dealer measured tread depths at 5/32, 5/32, 4/32, and 3/32 (rear tire at replacement threshold). This level of wear is abnormal for the mileage and creates a safety concern due to reduced wet traction and hydroplaning risk. Dealer inspection dated 12/16/2025. Mazda USA case number 00394959.

Steering became Notchy and in left turns only steering wheel would bind or stick when exiting a turn at a speed between 30 to 50 mph. Problem became significantly worse over course of a few days.

I was stopped by a railroad crossing and when I started driving, my automatic emergency braking activated and jerked to a stop. This happened two consecutive days in a row. Gratefully no one was behind me, or they would have rear ended my vehicle.

On or about [XXX], I leased a 2025 Mazda CX-90 PHEV Premium Sport from Bob Penkhus Mazda, Colorado Springs, CO. Within approximately six weeks, on [XXX], while traveling south on [XXX] from Pueblo toward Walsenburg, the vehicle experienced severe loss of power under load. Despite the accelerator being fully depressed, the vehicle would not exceed 74 mph on the initial incline and later would not accelerate past 64 mph near La Veta Pass, even in sport mode. During an attempt to pass a slow-moving truck, the vehicle failed to accelerate, forcing me to brake hard to avoid a head-on collision. My fiancée and our infant twins were in the vehicle at the time. I immediately contacted Service Manager Steven Constable at Bob Penkhus Mazda. The dealership retained the vehicle for inspection but claimed they “could not duplicate” the issue because “they don’t have mountains to drive it up.” No repairs were made. Instead, I was told to “drive it for 30 days to monitor,” despite the documented safety risk. I refused to assume that risk and requested a repurchase, replacement, or trade into a non-PHEV model. I even offered to accept a lower-trim base model, provided it had captain’s chairs, and to continue paying my current monthly amount. The dealership and General Manager A.J. Ager rejected this and demanded that I personally pick up the unrepaired vehicle, although they knew I live three hours away in Monte Vista and Mazda advertises complimentary pickup service.

After driving >2000 miles or about a month, I could hear a loud, grunting/grinding noise when accelerating aggressively from 1st to 2nd gear when on EV or gas mode. Brought the vehicle at the dealership service department 4 times already, each time MAZDA Headquarters in California confirmed that this is a known and documented condition. According to Mazda, the grunt noise you’re hearing when the vehicle shifts from first to second gear under medium to aggressive throttle is considered normal operation. It has been determined that this does not affect the drivability or reliability of the vehicle, and it is safe to drive. The transmission is operating as designed and performing within normal parameters. Mazda is continuing to collect data on this condition as part of their ongoing commitment to improvement. However, I totally disagreed to their answer and that the truth is that they don't know how to fix it, unless tearing down completely the transmission to find out what the cause is! I feel it is a safety problem as explained by a top transmission repair shop: "In most cases, a loud, grunting or grinding noise when accelerating from 1st to 2nd gear would likely be considered a defect that substantially impairs the vehicle's use and could also affect safety, particularly under the context of Oregon's Lemon Law. Here's why: •Impact on Use: Grinding and grunting noises suggest that the transmission is not functioning properly, according to Top Notch Transmissions. This makes the vehicle less reliable and less enjoyable to drive. If the problem persists or worsens, it can hinder the vehicle's ability to operate safely and effectively, potentially leading to hard or delayed shifting, or even transmission failure."

Near a roundabout the car in front of me started moving and braked. My car didn’t give any forward collision warning or proximity alert before my car hit the other car from back. The speed was less than 12 mph.

The car automatically brakes at lower speeds. This happens about 3x week and typically on a specific freeway entrances but in other locations as well. I believe this is a known phantom braking issue but for some reason my car is not included in the recall.

The drive power on my 2025 Mazda CX-90 was SEVERELY reduced last week while making a left turn in front of oncoming traffic. No warning light nor sound from my car appeared at the time of this incident. The vehicle was purchased 5 months ago and there have been other occasions where the power was reduced while turning. This incident, however, was the most dangerous. The turn was made at a traffic light while sitting on a hill yielding to oncoming traffic. The approaching car was moving slow enough to make a safe left turn in front of it, but the lack of power prevented me from making a reasonable (not reckless) fast turn. Fortunately the oncoming vehicle was able to stop in time to prevent an accident.

The Mazda CX90 PHEVs i-activesense system that controls the adaptive cruise, lane departure and lane keep assist system disables at random times with a message "i-activesense temporarily disabled. front radar obstructed." There is never any objects obstructing the radars and no outside weather/elements affecting it. It will not turn back on either, even though it should turn back on if the obstruction is cleared from the radars/sensors. Since there isnt anything to clear when it happens, it stays disabled unless the vehicle is turned off completely and back on. I have had this vehicle for 2 weeks and it has disabled on the interstate traveling 70+ mph and on city roads in congested traffic over 15 times. When it happens with the cruise control enabled, it immediately begins decelerating quickly, causing a safety issue when on the interstate at high speeds. Was brought back to service 24 hours after acquiring the vehicle but Mazda cannot seem to figure out what is wrong with it. Its a huge safety issue when it all disables and the car quickly decelerates without any warning. Has happened on multiple dates, at least 15 times in 2 weeks, at various speeds with 75 mph being the fastest.
