NHTSA Complaint #11456585 — 2018 ACURA MDX

When trying to accelerate after braking the vehicle has a MASSIVE hesitation where it just sits there doing nothing literally for a solid second. Not only being very frustrating it's IMO very dangerous. If I'm at a yield and then need to merge quickly, if I'm getting on a highway from a parking lot, if I'm trying to switch lanes in traffic, etc etc the vehicle just bogs down and does nothing for that 1-2 seconds. Drive the vehicle normally, apply the brakes and then right away take your foot off the brake and accelerate. You don't have to mash the accelerator, even with light to moderate pressure you will notice that lag where the vehicle is just sitting there with zero power. If you do accelerate moderately or hard after a second or 2 of doing nothing it will just completely jerk into motion. Does the same thing in all modes, it's actually worse in Sport and Sport+ mode because you get more power after the hesitation After braking moderately hard from 40mph to 15mph because someone cut in front. Then I changed lanes and had to accelerate because that other lane was going quite a bit faster. Hit the gas and nothing for what seemed like the longest 1.5 seconds until the thrust came back online Pattern: From Stop --> Accelerate for about approx 20 MPH -->Release the gas pedal and immediately apply the gas pedal. Another pattern: Travel in about 40 MPH, apply the brakes to a speed below 20 MPH and apply gas pedal. Consulted with the dealer multiple times and they think this is normal for 2018 MDXes. But it is indeed a safety concern. The dealer said they applied TSB 20-015 TCM update and it still has not resolved the problem. THIS IS A HUGE SECURTY ISSUE and DANGER HAZZARD. The issue happens every day. Below reported date is the latest occurrence.
