Infotainment system went dark and I cannot get it to come back on. I’ve read that this has been an ongoing issue and is covered in Mazda cx5 models up to 2020 thru a class action lawsuit, but my one is a 2021 (manufactured we’ll before 2021 though) with a virtually identical system.

My car is experiencing extreme ghost screen. Also when this happens I get a lot of warning lights when nothing is truly experiencing fault. My screen will jump, change settings, reset settings,become dark on it own, not turn on at all, flip through the system causing major distractions. For instance I was driving in my car with quiet no noise then my screen jump and without warning blasted am and scared the living heck out of me while on the highway. It has called people and hung up on its own. Lights flicker and one side of my top lights don't work. My plugin have no electricity coming to them.There are times I have trouble connecting to Bluetooth.

The info uni in the car constantly resets itself. It happens when GPS is activated, parking, listening to directions, pretty much at all time especially in crucial moments. Nav center doesn't even load at times, this causes unknown information of speed limits and streets.

Car “died” while idling at a traffic light. It started but would not start several hours later and car was towed to mechanic. Diagnostics “determined “after several days that car needed an ECM. ECM was ordered and replaced, along with the battery. This took several weeks, in the meantime, I had to rent a vehicle. Vehicle picked up on May 29th and driven 250 miles and car sputtered, hesitated, slowing down in heavy traffic at high speeds on highway, putting other drivers and myself in a very unsafe situation. Several days later this happened again while traveling back home, again, at highway speed putting other drivers and myself in high risk situation. (This happened several times during both trips.) As I was focused on the road, I did not see if any messages were displayed. After returning home, the mechanic was informed via voice mail and again via telephone. The following morning (June 2), the car sputtered, hesitated to accelerate at low speeds and died while driving to repair shop (battery indicator illuminated as I was pulling over). Car has been towed again to repair shop.

Sometimes, the breaks will not go all the way down to the floor and act like theyre not working. it's very odd and only does it once in a while. i have constant issues with the technology in the car. it changes my music, the buttons get stuck and my it acts up. my aunt has the same model and is running into the same issues. i never received a letter in the mail about the last recall and have had issues where it doesnt seem like my engine is getting the power it once did. this was early on after i got the car. my gas mileage has significally decreased even after oil changes.

Summary of Events: Purchase Date: 05/27/2023 Coolant Warning: In January 2025, I received a coolant temperature warning (code P0126) indicating insufficient coolant temperature. Repairs: I brought the vehicle in for repairs on 02/15/2025 for thermostat and related parts. The repairs were completed by 02/17/2025. New Warning: On 03/18/2025, I received a high coolant temperature warning. Upon inspection, coolant was nearly empty, and I found coolant contamination in the engine bay. Notification to Dealership: I emailed Hennessy Mazda on 03/19/2025, but after no response, I filed a claim with Mazda headquarters on 03/20/2025. Only after that, they called me and instructed me to bring the vehicle in. They claimed that after replacing the faulty parts and cleaning the engine bay, the car was ready for pickup. (While they assert that all actions were completed on 03/22, Based on the fact that the car door was opened approximately five times in April, it can be inferred that the necessary actions were likely completed in early April.) Concerns: Coolant Leak: The coolant leak persisted for nearly a month, likely causing damage to internal components due to engine overheating. Electronic Contamination: The leaked coolant likely contaminated sensitive electronic systems, wiring, and connectors, potentially leading to long-term failures due to the conductive and corrosive properties of modern coolants like Mazda FL22. Long-Term Risks: Hidden corrosion inside connectors and wiring. Potential for electrical failure, sensor malfunctions, and further degradation over time. Hennessy Mazda is currently addressing only the visible issues and claiming the car is now functioning properly, while attempting to shift the long-term and hidden risks onto me. I am requesting a vehicle replacement or compensation due to the safety and long-term reliability risks posed by the unresolved coolant leak and contamination.
