Adaptive Cruise Control Problems of Acura MDX - part 2

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.

On 8/20/23 heading south on I-294 in chicago : in center lane with cruise control on and no cars close in front of me when the car suddenly started a hard braking without warning. No orange warning to brake came on but engine warning light of left of dashboard was on. Immediately turned off cruise control. Car would not accelerate and came to a stop on the highway. Tried to start without success, then restarted and the car came on but in neutral. It had been placed in park before shutting off. Car started and drove uneventfully back to indianapolis. Took to Acura dealer and diagnostics were run showing that "position range" switch or sensor had been activated. Told it was safe to drive. We do not agree and are selling the car. Dealer, or service dept was very lackadaisical about the incident. I will contact Acura corporate headquarters as well.

My car was purchased with 12,000 miles and supposedly worn tires. Because of that, I went to the dealership to get new tires and an alignment since the car was always pulling to the right. My car has been at the dealership four times for the same problem, and they still haven't fixed it. My car continues to constantly pull to the right, and when I use the cruise control, it stays above the other cars to the right, causing it to suddenly pull to the left, deactivating the speed control and losing control. The dealership's recommendation is to stop using the speed control. ".

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.

My vehicle has similar behaviors to the most recent investigation that is happening with the investigation of the Honda accord and crv noted in this article: https://static. Nhtsa. Gov/odi/inv/2022/inoa-pe22003-5540. Pdf. On a handful of times while driving on the freeway, my car has unexpectedly decelerated when passing another vehicle, or on a curve the adaptive cruise control slows the vehicle down. On one occasion, the car suddenly applied the brakes and slowed us down at least 10mph. In any of these instances, I have not had anyone following, but could have caused issues if there was.

I was driving on a 80-mph 3-lane one direction (6 both) toll road, following a TX state trooper. About a 1/4 mile ahead of me were two waste disposal trucks. One in the right land and one passing the other in the center lane. The trooper and I pulled into the left lane. As we approached the waste disposal trucks (about 1/8 mile away) my brakes automatically engaged and braked hard for no reason. I tried to override it by depressing the accelerator but the accelerator did not respond (as though it had been disengaged). Behind me was a mercedes SUV, which had to brake hard to avoid rear ending me. My brakes kept automatically braking (off and on). I finally pulled off the road on the left shoulder and brought the car to a complete stop. It then allowed me to proceed on my way. I bought the car in part for this safety feature, but it clearly is faulty. In reading about braking system, I found that older models had a button that you could use to turn the system off. In my 2022 model, you can turn it off only with multiple steps. You can also adjust the responsiveness of the auto-brake system through a multiple step process. Clearly, this is a major problem that needs to be addressed. I was very lucky that the car behind me braked immediately or it would have rear-ended me at high speed. It was about 5:30 p. M. It was getting dark but not completely dark. I think the problem is with the automatic braking system for forward crash avoidance, but my adaptive cruise control was engaged.

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.

While driving with adaptive cruse control on, I was approaching slower vehicle. I wanted to go around it without breaking. While driving already on high speed (70m/h) I press acceleration pedal so I can safely go around slower vehicle. I was half way into passing line (last left line), there was a car already behind me approaching with higher speed, when I suddenly completely lost power and lots of lights illuminated on the dash. Car behind me notice that I start loosing speed rapidly so he start braking that I could hear his tires. I didnt know what to do so I just kept going to emergency stopping line where I almost crash into the concrete divider. I manage to stop vehicle safely by pure luck. After stopping I notice that car is not shifting, and sh-awd system, blind spot ass, emission system and transmission system fault lights came on. I called insurance agent to send road side assistance, but while waiting on the call I start the car again (like 15min after this incident) and all lights were still on except transmission. I tried car and it was shifting normally now, except sh-awd was not working (I didnt have power to the rear differential). This could be very tragic event if both me and the driver behind me didnt react properly. I had two more passengers in the car, from which one was 15 months old child. I was reading that this could be transmission system update issue, but my dealer did update transmission already.

While driving at highway speeds with the adaptive cruise control engaged, the vehicle detects vehicles to the right (same direction of travel) or at times vehicles to the left (opposite direction of travel) and abruptly applied backing. No vehicles will actually be in lane of travel of the vehicle to cause action. On a 87 mile drive (one way to work) happens more than eight times on first drive and over ten time on second drive. Vehicle has under 1500 miles on it and was purchased brand new. Taken to Acura and told to turn off lane departure system unless in city traffic. System turned off and did not correct issue. The abrupt braking causes drivers behind to abruptly brake, increasing risk of crash, and also angers them because they think you are �brake checking� them. Weather was cloudy or clear.

Cruise control stopped working 5 years ago after acc lkas stopped working. I have had the car into multiple Acura certified dealerships attempting to repair and no one has been able to determine the issue.

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

There was a couple times where the car stalled at a red light. Also, there are a lot of times when I press the push to start, it will not start, advising me to place the key fob near the push to start. I find this to be dangerous when driving and very annoying when attempting to start and it doesn't start.
