Editor's note
Avoid the 2019 and 2020 RDX, which score 32 each on 433 and 344 complaints, and the 2015 at 39 on 409, with the 2014 (50) and 2021 (51) as CAUTION years to walk past. Buy a 2016 to 2018, which score 89, 88 and 84 on 40, 75 and 77 complaints, or a 2022 to 2024 at 83 to 84 on 31, 21 and 11.
