NHTSA Complaint #11696077 — 2024 HONDA CR-V

My 2024 CR-V EX-L FWD has roughly 37,000 miles on it, and the tires have been rotated per Honda's built-in "Maintenance Minder". The inner shoulder of all four tires are worn to the extent that they need to be replaced. The rear suspension suffers from excessive negative camber; It is visually discernable upon approaching the vehicle from behind. I asked the service advisor at my local dealership in League City, TX, what they could do about it, since the rear camber is non-adjustable, and his response was that in situations like this, they recommend installation of aftermarket adjustable upper control arms. They, of course, do not install those parts, and, he even indicated that once those were installed, they would no longer perform any alignment of the vehicle. Additionally, that would void any warranty of any rear suspension components. I have since discovered Honda TSB 20-081 for 2017-2020 CRVs (https://static.nhtsa.gov/odi/tsbs/2020/MC-10181080-0001.pdf). I know, via comparison of part numbers on honda parts websites, that 2017-2026 CR-V's all share many of the same rear suspension components. Therefore, I think this is a situation where there is an overarching issue in the suspension design used on the 5th and 6th generation CR-V (and therefore, also their contemporaries - Civic, Accord, HR-V, Clarity, and Acura Integra, which also share components with this design). Additionally, the rear of my CR-V looks to be 'sagging', and knowing how suspension geometry functions, it leaves me thinking that perhaps the springs specified for the FWD CR-V (at least) may be too short or have too light of a spring rate, permitting this 'sag', which would then not only result in more negative camber but also increase the toe measurements as well, which would also negatively affect tire life.
