It seems that, from the day we purchased the vehicle, there have been issues with the transmission regarding how it is programmed and how it responds to drive or input through the throttle. This causes the vehicle the occasionally lurch forward under acceleration, especially at low speeds in the parking lot. And times the throttle gets really confused and the transmission fails to deliver power to the vehicle for a second. This has happened to me two or three times. I was turning left when the vehicle lost power momentarily and oncoming traffic was headed straight for me and my vehicle. If the delay had lasted just a while longer, things would have looked very bad. Based on my research online, I am not the only driver experiencing this kind of problem with the transmission.

Additionally, the contact was unable to shift into park (P) or into neutral (N) as the gear shifter became stuck into drive (D) position. The contact stated as he turned off and restarted the vehicle several times, the gear shifter responded as needed. Several unknown warning lights were illuminated. The vehicle was taken to the local dealer who informed the contact that they could not duplicate the failure. The vehicle was not repaired.

Gas petal is very touchy. It accelerates to fast even when you try to barely push the petal. And causes to shift hard.

On a regular basis, if accelerating to cross an intersection, car stops or hesitates for several seconds. We have almost been hit by cars several times in the past year. Dealership states everytime i have it serviced, they are unable to replicate and they have never heard of this. In a 5 minute internet search I have found many references to the same issue.

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.

Car miss shifts especially in the 25 to 40 mph range. Sometimes hesitates when taking off. Also stays in one gear and will not upshift when entering the Freeway. Very dangerous. I found numerous complaints on the web in reference to these problems, but still no recall"?" Have told the dealership about these problems with every service, but they said that there is nothing wrong.

6 months after delivery of my vehicle I stated noticing a jerking when my transmission shifts. I have taken my vehicle to the dealer indicating my concern. Each time the dealers said the could not duplicate. The problem continues. The second issue has to do with my brakes. On 9/23/2019 my brakes started emitting a loud persistent squeak. I am scheduling an appointment with my dealer. My vehicle is a little more than a year old and it seems to me that at 30,000 miles constitute premature brake ware.
