MAZDA Complaints

The infotainment system in my 2017 Mazda CX-5 exhibits dangerous behavior consistent with known defects described in the Mazda Infotainment Class Action Settlement (Case No. 8:21-cv-01355). The infotainment system and touchscreen repeatedly activate critical functions on its own (“ghost touches”), sometimes going black, changing critical settings, disengaging phone calls as well as unexpectedly activating phone calls, and navigation features engage or freeze unpredictably. These malfunctions distract from safe vehicle operation, requiring driver attention to manage the malfunctioning display. The vehicle’s display is integrated with backup camera, audio, and Bluetooth controls, so these repeated malfunctions cause safety concerns while driving. Mazda and the dealership have refused to repair the defect under the Limited Warranty Extension established in the settlement, incorrectly claiming the issue is unrelated to the CMU (connectivity master unit). However, these symptoms are identical to those described in Mazda’s internal service bulletins (CSP13 and TSB 09-022/17) and covered by the settlement. I believe Mazda is failing to properly address a continuing safety-related defect that impacts infotainment stability and driver concentration. These issues have occurred for years and are continuing nearly every time I operate the vehicle.

Vehicle suffering from Mazda TSB 05-005/23 Chirping noise from Transaxle on 3rd to 4th gear upshift. Vehicle diagnosed by dealership as needing new Transaxle on 17OCT25. Diagnosis stated issue started ~32k miles.

2018 Mazda CX-5, 2.5L NA Has been diagnosed with leak in the cylinder head cover, which has resulted in engine oil leaking directly onto the exhaust manifold. This leak produces significant smoke and a strong burning oil smell while the vehicle is running. There are numerous reports on Mazda owner forums describing the same issue occurring in Mazda CX-5 models. Some owners even reported instances of minor fires or active burning under the hood due to oil contacting hot components. Mazda released Technical Service Bulletin TSB #SA-031-21, which includes a redesigned cylinder head for the 2018–2019 CX-5 models. This bulletin demonstrates Mazda’s awareness of the design flaw. The TSB only covers turbo 2.5L engines and not normally aspirated engines. There is substantial evidence that this is a widespread defect in these model years, unrelated to owner misuse or vehicle mileage. Mazda should take full responsibility by issuing a formal recall or providing an extended warranty to address the problem and prevent safety risks.

In June of 2022 I started having a strong antifreeze/engine coolant smell inside the cab of my vehicle and also outside the vehicle. I had the car checked for a radiator leak, but there wasn’t one. I took my car into my local Mazda where they found that the engine coolant was leaking into the heads of the engine. Mazda kept my car for 5 months and repaired the problem, it cost me $4000 and they had added a 12 month 12,000 mile warranty for the parts. My car is a 2016 Mazda cx-9 at the time of the repair it had 70,430 miles on it. Now a few years later I am having the same issue with the coolant smell inside the cab and outside my vehicle, it goes into the shop for diagnosis on Monday November 10,2025. The car now has 118,000 miles on it. I had purchased an extended warranty for the car at the time of purchase but it had timed out a month before I took my car in for the first repair….please Mazda stand behind your vehicles I am a senior woman with very little income and I will not be able to pay out of pocket for this repair and I CANNOT afford a new car… I would like to get reimbursed for my out of pocket on the first repair and get my car repaired this time as well under a warranty.

All of the door handles and locks have loosened and fallen off. Sliding door will not latch now. Hatch on rear has lost suspension.

I am submitting this formal complaint regarding a potential recall failure involving a 2005 Mazda Tribute driven by my fiancé, [XXX], who died following a crash on [XXX]. Mazda has opened Case #[XXX] in response to my inquiry, and I am requesting federal oversight of this investigation. Joey’s vehicle may have been affected by NHTSA Recall 12V357000, which addresses throttle body malfunction and unintended acceleration. Service records show that a dealership performed a recall service, but the parts used may have been ineffective or incomplete. The crash sequence—rear-ending a stopped vehicle followed by veering into oncoming traffic—matches known symptoms of this defect. I am requesting: •A formal review of Mazda’s handling of Recall 12V357000 •Verification of Joey’s VIN-specific recall compliance •Investigation into the dealership’s repair actions and part quality •Oversight of Mazda’s internal case (#[XXX]) and its findings This issue raises serious concerns about manufacturer accountability and public safety. I am submitting supporting documentation and service records for review. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
