While driving down highway the car suddenly will stop accelerating. Once this occurs the check engine light will turn on and shortly after the battery light will turn on. The car will not move and the AC will then stop working. The first time the car was brought to dealership (under warranty). They had to replace battery, fuel pump and fuel level indicator. They stated the fuel pump was broken as was the fuel level indicator. They were able to reproduce the problem prior to fixing it the first time. Less than a month after the car was repaired the exact same issue happened. This is a significant safety concern as I was driving on the highway with a [XXX] child in the back seat when the car stopped driving the second time. I was barely able to get over a lane and off the road before the car stopped driving. The AC then stopped working on a day where the feels like temperature was over 100. I had to lay wet cloths over my infant to prevent her from overheating while we waited for AAA and a family member to reach us. The inability to accelerate/sudden stopping of the car while driving on a highway with a speed limit of 70mph posed a significant safety risk to my life, my child-??s life and potentially other cars if they weren-??t able to stop. I had to wave frantically at the car in the lane next to me so that they wouldn-??t hit me. No warning lights came on until after the issue (stopped accelerating) occurred. The dealership (Mazda) now has the car again and will be inspecting it. I have files from the first incident however they are in the car. Once I get my car back I can send over the reports of what they replaced/work completed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Mazda-??s CX-5 engines, particularly in earlier models, have been known to experience issues with Hydraulic Lash Adjusters (HLAs), which are responsible for maintaining proper valve clearance. Many owners have reported a persistent tapping or ticking noise, especially during cold starts. This issue is often caused by air bubbles or insufficient oil supply to the HLAs, and cold weather exacerbates the problem as thicker oil struggles to circulate until the engine warms up. The HLAs have also faced criticism for their sensitivity to oil pressure and quality, making them prone to failure in less-than-ideal conditions. Mazda claims that replacements and redesigns have resolved these issues in newer engine models and has not issued any Technical Service Bulletins (TSBs) for models after 2021. However, I experienced the HLA -??ticking-?? noise in my 2022 CX-5, suggesting the issue has not been fully addressed. I am concerned about the longevity of these parts and potential repair costs in the future, as Mazda seems to be dismissing the problem. I have a video capturing the noise but cannot attach it to this form. If interested, please contact me, and I can provide the video. Additionally, there are countless videos of similar issues shared on the CX-5 subreddit, which can be found by searching -??clicking-?? at the following link: [XXX].

The vehicle unexpectedly caught fire and the results could have been catastrophic. Almost new car under warranty. All details are in the uploaded PDF letter and photos. I have contacted Mazda and they claim they do not investigate, only insurance company will investigate. My insurance company will pay me for the total loss but does not plan to investigate. I think this is dangerous and unconscionable. Thank you for any help or guidance.
