I'm curious how many other Mazda owners are dealing with the same battery drain issue. I'm now on my third battery since 2024: Factory battery replaced under warranty in 2025. Second replacement purchased in March 2026. Within a month, the Battery Low - Drive Vehicle to Recharge warning was back. The dealer kept my vehicle for four days to monitor it, but they couldn't find anything abnormal. This started long before I had a dashcam professionally installed, so that's not the cause. I've read…

The vehicle's Connectivity Master Unit (CMU) suffers from a severe, persistent electronic hardware malfunction that causes the central information display and dashboard telemetry to blink, cycle, and drop signals erratically. This specific hardware architecture failure threatens to corrupt data transmission lines directly connected to the Advanced Driver Assistance System (ADAS), creating an imminent safety risk of unintended automatic emergency braking or false sensor deployment during highway…

I am writing to formally notify you that I have officially filed comprehensive complaints with the NHTSA (National Highway Traffic Safety Administration), the Tennessee Department of Commerce and Insurance (TDCI, Case #202604748), and the Better Business Bureau (BBB) regarding Wyatt Johnson Mazda. I am submitting my vehicle's official Warranty Vehicle Inquiry Report as evidence of consistent technical issues and mismanagement by Wyatt Johnson Mazda. Please note the following: History of…

The cylinder head on this 2018 Mazda CX-9 (Skyactiv-G 2.5T engine) cracked, allowing engine coolant to leak and intermix with engine oil, causing loss of coolant and catastrophic engine failure. The vehicle became undriveable in the first week of November 2025 at approximately 125,019 miles and has remained inoperable since; it was not in a crash and had to be towed. This matches a known, documented defect on Mazda's Skyactiv-G 2.5T engine: coolant leakage at the cylinder head near the exhaust…

Was braking with traffic and all of a sudden the emergency braking kicked on and brought the car to a stop from about 40 miles per hour with no immediate threat of collision. Brakes were being applied manually and had plenty of room infront of the vehicle and traffic was not stopped. Nearly caused the vehicle behind to collide into me. Very uncomfortable whiplash feeling experienced and my unsecured belongings in my car went flying.

I own a 2026 Mazda CX-90 hybrid with approximately 13,000 miles. The vehicle began making a grinding noise while driving, which has progressively worsened over time. It has since developed a hard knocking noise accompanied by noticeable vibration when the vehicle shifts gears. This knocking occurs during normal in-town driving. I have taken the vehicle to the selling/authorized Mazda dealership on two occasions — June 2, 2026 and July 14, 2026. On both visits, the dealer was able to reproduce…

I have a serious safety issue with my 2025 Mazda CX-5, purchased new in January 2026 from Island Mazda on [XXX]. A few days before the critical alert, I noticed the car stopping on its own before pressing the brake. While driving on the highway, I received a “faulty sensor” alert that went away. On July 10, 2026, I received a Critical Vehicle Malfunction Alert in the MyMazda app. The app gave no specific details. I called Mazda Customer Experience. They confirmed via email the system labels it…
