NHTSA complaint #11646392

Owner complaint summary

I am submitting this report to document a persistent ticking noise in my 2022 Mazda CX-5, which appears to be the same issue outlined in Mazda Service Bulletin 01-002/21 for previous model years. This issue is commonly associated with Hydraulic Lash Adjusters (HLAs), which maintain proper valve clearance. The noise occurs most prominently during cold starts and resembles the previously reported HLA ticking sound. Owners of earlier CX-5 models have attributed this issue to air bubbles or insufficient oil supply within the HLAs, with cold weather exacerbating the problem due to restricted oil circulation. Despite Mazda's claim that revisions to the engine components have resolved this issue in newer models, my experience suggests it remains unresolved in the 2022 model year. I am concerned about the long-term reliability of these engine components and the potential repair costs if the issue leads to premature wear or failure. While Mazda has not issued a Technical Service Bulletin (TSB) for the 2022 CX-5, multiple owners have reported similar ticking noises online, indicating that the problem may persist. I have a video recording of the noise but am unable to attach it to this submission. If further investigation is warranted, I would be happy to provide the footage upon request. Additionally, similar reports and video evidence from other owners can be found on online forums, including the CX-5 subreddit, where searching for “clicking” will yield multiple examples. I urge the NHTSA to review this issue, as it may indicate an unresolved mechanical defect affecting the reliability of the 2022 Mazda CX-5’s engine. Please advise on any potential investigations or next steps regarding this matter.
