2026 Mazda CX-90 Owner Complaints

On multiple occasions, the steering wheel became stiff or locked while driving or during start-up, multiple dashboard warning lights illuminated, and the vehicle could not be shifted from Park to Drive. This occurred repeatedly since the vehicle was purchased. The dealer inspected the vehicle multiple times; on the first attempts they could not duplicate the issue. On a later visit, the vehicle displayed a lost communication fault with the electric power steering (EPS) system, and the dealer replaced the steering gear/rack assembly and EPS motor per the manufacturer’s technical hotline instructions. Despite this part replacement, the same steering/warning light condition recurred weeks later. At that point the dealer confirmed the defect but stated there is currently no authorized repair or parts replacement available, and that engineering is developing a permanent corrective action. The vehicle remains in my possession and is available for inspection. This defect creates a serious safety risk because the vehicle cannot be steered or shifted normally when the condition occurs, including while driving. No crash or injury has occurred to date.”

While driving approximately 50 mph, we heard a sudden, extremely loud bang, followed immediately by the sound of shattering glass. We pulled over and discovered that the panoramic sunroof had shattered and appeared to have exploded outward. There was no collision, no object that we saw strike the vehicle, and no warning before the failure. The glass remained largely in place but was completely fractured. This occurred while my family was in the vehicle, including my young children. The sudden explosion startled the driver and created a potentially dangerous driving situation. I am concerned that a spontaneous sunroof failure at highway speeds could cause a driver to lose control of the vehicle or result in injuries from flying glass. I am reporting this because I believe it represents a serious safety issue that should be investigated to determine whether this is a manufacturing defect or other vehicle safety problem.

Instrument cluster will reboot during braking at random times. All warning lights turn on, gauges go to zero and front wipers are set off. This happens for 1-3 seconds. Mazda replaced instrument cluster but only made issue worsen they said it’s safe to drive but very distracting especially when turning onto busy roads. Currently being experienced by multiple other vehicles, so not isolated. Bought in February 2026 and started in early March 2026, currently still an issue as of June 2026.

The contact stated while driving at approximately 20 MPH, the contact discovered that while the front passenger seat was not occupied, when the passenger did not weigh enough the front passenger side air bag was inoperative; the contact stated that while the front passenger seat was not occupied the "fasten passenger seatbelt" message was displayed on the instrument panel and the fasten seat belt alarm went off. A dealer was contacted however, the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 2,133.

Vehicle experienced multiple safety-related failures at approximately 500 miles. The failures included complete instrument cluster loss (no speedometer or gauges), unpredictable windshield wiper operation, headlight flickering, complete loss of brake lights and turn signals, rear liftgate malfunction, and airbag/seatbelt warning indicators. These issues created unsafe operating conditions, including inability to monitor vehicle speed, loss of rear signaling and brake indication to other drivers, and uncertainty regarding airbag system functionality. This presented a risk to both the driver and surrounding traffic. The failures occurred intermittently and in combination, indicating a potential systemic electrical issue rather than a single isolated component failure. The vehicle has been taken to an authorized Mazda dealership and is currently under inspection and repair. The dealership has indicated the instrument cluster requires replacement and is currently on backorder. Full root cause has not been confirmed. Warning indicators, including airbag and seatbelt system alerts, were observed prior to and during the failures. Additional symptoms included erratic system behavior across multiple vehicle functions. Vehicle remains at dealership with no confirmed repair completion date. Component is available for inspection upon request through the servicing dealership.

The contact owns a 2026 Mazda CX-90. The contact stated that while driving at undisclosed speeds, the steering wheel was pulling to the left, causing the vehicle to merge into the left lane unintendedly. The contact firmly held the steering wheel to prevent the failure. Additionally, the vehicle jerked to the right lane while the lane keep steering assist function was activated because the steering wheel was pulling to the left. No warning light was illuminated. The vehicle was taken to the dealer, but no cause of failure was found. The failure persisted, and the vehicle was taken back to the dealer, and an alignment of 0.1 degrees was performed; however, the failure recurred. The vehicle was taken back to the dealer for the third time, and the contact was informed that no repair was available and was advised to contact the manufacturer for assistance. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 100.

I am reporting a safety defect involving my Mazda CX-90 with approximately 1,400 miles. The vehicle emits strong chemical fumes into the passenger cabin during normal operation. I first noticed it the night I purchased the vehicle when I was driving it home. The fumes occur both with and without the HVAC system in use. Once present, the odor lingers inside the cabin for an extended period, even after the vehicle is turned off. The exposure causes physical symptoms, including headaches, burning eyes, watering, and irritation while driving. The severity of the symptoms raises concern that harmful fumes or gases are entering and remaining inside the vehicle cabin. The vehicle has been taken to Mazda service centers twice and it is currently there for the third time. The dealerships have stated they are unable to detect the odor and has not performed any effective repair. The condition persists and continues to affect occupant safety. This issue is not consistent with a typical “new vehicle smell.” The intensity, recurrence, and physical symptoms suggest a potential defect allowing chemical or exhaust fumes to enter the passenger compartment. I am submitting this complaint due to concern for my safety and the safety of passengers, and to request investigation into whether this is a broader defect affecting this vehicle model.
