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.

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.

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.
