Adaptive Cruise Control problems of the 2017 Acura MDX

There are warning lights for all safety modules, the lkas, headlight warning system accident prevention system, collision avoidance system etc. .

I have a 2017 Acura Mdx that had around 98k while I was driving down the highway at 65 mph all lights came on the dash and lost acceleration would not go over 45 mph on a very busy highway. Had to have the vehicle towed per dealership- towed to jay wolfe Acura, overland park, KS. They said engine needed to be replaced due to the miss fire of rod knocking. There was no other option for replacing the rods had to replace the engine. In addition they replaced with an used engine that is a 2016 not even the same year. Dealer made us aware of the recall for this issue but advised us the VIN# is not under the recall so we had to pay out of pocket. I have tried to work with Honda and the dealership for reimbursement since there have been numerous vehicles with this exact issue but the VIN#'s not under the recall but with no help at all. I have provided documentation and explained the issues and the repairs. I have documentation but was not able to add it to the document listing below.

I had the transmission system failure error came on the dash and the car wouldn’t drive to d or reverse then blind spot and adaptive cruise control error propped up.

Driving east on interstate 20/59 10 miles east of meridian, ms November 17, 2021 around 2:00 pm. A lot of trucks on the road. Had speed control set at 69 mph. Came up behind a semi doing about 65, pulled over to the left lane to go around him. When I got about half way all of a sudden all hell breaks loose. Vehicle goes in into emergency stop with lights flashing all over the dash. Vehicle brakes to around 30 mph within a couple of hundred feet with semi's and cars beside and behind me. Finally got the vehicle over to the side of the rode without and accident. (a miracle inself). Code dtc p0716. After about an hour of shutdown, started engine and all messages were gone. Took it to the Acura dealer and they, evidently, updated the tcm software. I had not been notified that it needed and update which is negligence on Acura. This incidence could have been a catastrophe with possible deaths. Now my wife is really afraid to drive this vehicle.

On multiple occasions (6 times within a week) the powertrain loses power. While traveling 60 mph in 4 lane interstate traffic engine loses all power and accelerator ceases to respond. Passengers were at risk due to no power. Acura dealer has not been able reproduce. Some dealers have affirmed that they've had customers with the issue but can't reproduce. The issue seems to occur more frequently after cruise control has been dis-engaged. I have spoken with another a 2018 Acura owner directly and they have experienced the same issue. It does seem the engine/powertrain resolves when the transmission is switched from "normal" to "sport" mode. The amount of time with loss of power seems to span about 5-10 seconds.

Cruise control set to 37 mph, vehicle accelerates to almost 50 mph on downhill without braking.
