POWER TRAIN, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, SEATS
Internal vehicle fire started around front passenger seat and burned for an unknown amount time before it extinguished on its own while vehicle was off and parked. Fire department was contacted upon fire discovery and they confirmed it was out, could be electrically related, and disconnected my battery Vehicle is available for inspection for the time being (pending insurance). If I or any passenger was in the vehicle they could've been seriously injured or died. There were no warning lamps or issues of any prior problem.

ENGINE, ELECTRICAL SYSTEM, SERVICE BRAKES
While driving suddenly all error warnings came up. It included Check Engine Light, Error messages included: Electronic Braking System error, Emission System error. The light indicative of parking P! kept blinking also the (P) came up on the dashboard. Interestingly after some time this all cleared on its own. Then came back again only this time it stayed on. I don't know if this has compromised the safety features of the vehicle including emergency braking (crash avoidance/vehicle proximity)

ELECTRICAL SYSTEM, POWER TRAIN
I believe my transmission or the electrical component(s) to my transmission failed. I was driving down the road and all of a sudden my car shifted into neutral and would not allow me to accelerate so we had make our way to the shoulder to put the car in park. Having my vehicle thrown into neutral while driving and not being able to accelerate put not only us, but other drivers at serious risk! There were several warning messages popping up on our screen (see attached photos). In researching this issue, I found that there had been several TSBs and a class action lawsuit claiming the same issue faced by many drivers. It is currently at the Acura dealership getting serviced and they will be replacing the entire transmission and TCM harness under the CPO warranty. I cannot believe there has not been a recall on this potentially life-threatening issue.

EXTERIOR LIGHTING
The outside rear taillight was FULL of water. I discovered this when going to replace bulbs I thought were just burned out. In fact one of the bulbs was shattered I presume from the water reaching the hot light. The taillight is non functional and I will have to take it to be repaired/replaced. I should not have to pay for what is very clearly an manufacturer defect that compromises safe vehicle operations. Acura did a recall for the interior tail light for this same issue, but did not include the outer taillight. A simple google search shows this is not an isolated incident but rather a major problem.

POWER TRAIN
Every since I've owned my 2016 Acura MDX I've had infrequent, and intermittent transmission issues. Several have been safety concerns: - Transmission is slow to engage when first pushing accelerator, leading to unexpected lag pulling into traffic - Transmission did not shift into park as expected, causing car to keep moving as I was opening door and starting to step out - Transmission slips and does not respond when accelerating to merge into fast lane on highway to pass slower traffic. Car speed stalls and you have to let off the gas and wait for a few seconds before the transmission reengages. - Overall horrible/hard shifting all the time... to which we're told... the car learns your driving style. We've reset it multiple times to try to get it to start learning again. No luck. - After coasting on highway, very hard shift with loud noise when you go to hit the accelerator All of these situations have happened numerous times over the past 2 years of owning this car. All of them infrequent, but also unexpected... leaving you to really worry if this is the time the transmission is going to let you down and cause you to wreck. Dealer now says a new transmission is needed, but I waited until 78,000 miles to first report it, so it's out of warranty now. Hoping Acura will step up and address this serious safety issue with the 9 speed transmission.

ENGINE
Excessive oil consumption. I have the oil changed when the maintenance minder gets to 10%. Usually this is about 5,000 miles between oil changes. I will add oil to the engine at 50% oil life or 2,500 miles. I have contacted Acura and they are unwilling to address this problem. These engines need to be recalled. This is a reoccurring event.

POWER TRAIN, ENGINE
The vehicle makes noise while shifting from Park to Reverse to Drive. Transmission fluid and oil fluid leaking while I had driven only 450 miles. Had reported the issue to the Service Department. They informed that since the engine is new it will take a while for the transmission gear to quiet it down. They can't find any leakage for the first two times when I brought the vehicle for them to inspect. Their Service Manager was able to identify the issue and assigned the technician to trace it down. My car is currently in their shop for the third time since I just purchased it on August 19th, 2021.

At different times, either with my wife or I driving the vehicle, we will receive error messages on the dash indicating that various systems are inoperative. These involve the lane keeping assist system and the braking system. I also believe that the cruise control does not function when these messages appear.
