I am reporting a severe electrical fire and system failure hazard resulting from unauthorized, dealership-installed aftermarket wiring modifications on a brand new 2026 Mazda CX-30. At the point of sale, Walker's Renton Mazda ([XXX]) spliced invasive, unauthorized aftermarket tracking/security wiring (suspected LoJack or similar) directly into the factory CAN-bus and main wiring harnesses. These modifications were done without consent, actively concealed during the pre-purchase inspection, and compromise the integrity of the vehicle's primary electrical architecture. Specifically, the physical installation bypassed standard safety protocols and compromised the vehicle's firewall insulation. As a military electromechanical engineering veteran, I recognize that unauthorized taps into a modern vehicle's high-speed data network and main power lines introduce immense risk of short circuits, signal logic failure, parasitic draw, and most critically, catastrophic electrical fires. Despite providing physical evidence of the tampered wiring, the dealership's management has denied the modifications exist and refused to remediate the safety hazard by unwinding the compromised vehicle. Mazda North American Operations (MNAO) has also refused to intervene under Case #XXX. The vehicle remains in my custody, but it is fundamentally compromised and unsafe due to the dealer's tampering with factory safety and electrical standards. I am requesting NHTSA investigate this dealership's practice of covertly installing unregulated electronics into new factory wiring harnesses, as it presents an unreasonable risk to motor vehicle safety.

The high beams would turn on by themselves, and no matter what I did, they wouldn't turn off. Each time the high beams turned on, I would have to fiddle with the control stick for a few minutes until the high beams turned off. Sometimes they would turn off for a second and then just turn back on. This is dangerous as it can blind other drivers. This has happened ever since I bought the car a few month ago. On August 11th the control stick broke off while I was trying to turn off the high beams. Now I have no control over the turn signals or the lights. I brought it to the dealer, but they refused to repair it for free. This is a brand new car which is under warranty.

1.5 years after purchasing new my passenger side front door would not open from the inside. Mazda states car is out of warranty at 36837 miles indicating a cable had come disconnected. Approximately 1.5 years later at 59934 miles the front passenger door again would not open from the inside. Mazda states that this door is used frequently (it is not) and after troubleshooting replaced the door handle and lock mechanism on June 22, 2026. Other than having out of pocket expenses of $738 I feel fortunate that I wasn't exposed to a life threatening situation whereby leaving the vehicle through the passenger side was my only option. Searching forums online show that this failure is currently occurring to others. My hope is that Mazda will formally recognize this issue with the passenger side front door before someone is seriously injured.

I was driving my 2026 Mazda CX-30 in a parking lot and was pulling into a parking space at a very low speed. I lightly pressed the accelerator to move the car forward, but the car suddenly surged forward much faster than I intended or expected based on how lightly I had pressed the pedal. The sudden acceleration resulted in a collision and property damage. There were no warning lights, warning messages, or other dashboard alerts before or at the time of the incident. I do not know what specifically caused the car to accelerate this way. I am concerned that there may have been an issue with the accelerator/throttle response, engine controls, transmission, PCM, or another part of the powertrain. The vehicle has not yet been inspected by Mazda or an independent engineer specifically for this issue, so the cause has not been determined. It is currently as a collision center. Before the accident, I had also noticed that the vehicle's acceleration and pickup sometimes did not feel normal, although there were no warning lights or messages indicating a problem. I am reporting this because the car's unexpected acceleration at such a low speed created a serious safety concern. I would like the incident and vehicle to be investigated to determine whether a defect or malfunction contributed to the sudden acceleration. The vehicle is available for inspection.
Reporting Product Defect in Mazda Vehicles I am writing to bring to your attention a recurring design flaw affecting current Mazda vehicles, including models such as CX30, MX30, and potentially the Mazda3 series. Following heavy rain or high humidity conditions, there is a consistent issue with the tire pressure sensor alarming and the smart key being unable to unlock the car doors. I have checked my key fob battery, RF function, car battery - none of these are the root cause. Despite consulting local dealerships and various Mazda forums, no one seems to have a definitive solution to this problem. Therefore, I am reaching out to report the existence of this product defect. This issue appears to be more prevalent during summer in Arizona - after the thunderstorms, this issue came up every time. Even with the heat here, it takes from several hours to 2 days for the affected part to dry out and function again.
