I Noticed this on mine (XLT hybrid) about a month ago. I got it on 9/20/23. At first the rev sound going down long-steep grades was concerning but figured it was related to the battery regeneration. This forum confirmed it. Runs great and am pleased with its performance.
Most dealers in CA Mark up the Eco oost Maverick $5k and Hybrid Maverick 10k! Some Mark them up even more! The "market adjustments" are insane! The dealers say it's in part because people were getting them at MSRP and flipping them and making big profits. Unscrupulous dealers taking advantage.
