Adaptive Cruise Control problems of the 2022 Acura MDX

While driving with my small children in the vehicle, my 2022 Acura Mdx suddenly displayed multiple simultaneous system failures without warning and the steering wheel locked and the car slowed and the brakes didn't work well: •brake system problem – warning that braking performance may be reduced •electric power steering problem – “do not drive” warning •vehicle stability assist problem •hill start assist problem •all wheel drive system problem - •adaptive cruise control problem •collision mitigation braking system problem •lane keeping assist system problem •trailer stability assist system problem •brake hold system problem •vehicle stability assist problem •electric power steering system problem •low speed braking control problem •road departure mitigation system problem these failures created a serious risk to my life as well as my children's lives by simultaneously disabling braking, steering assist, stability control, and awd traction. If this had occurred at highway speeds or in a location without space to maneuver, it could have caused a severe crash and even death. The vehicle was towed to the dealer immediately. The tow truck driver stated that he had transported another 2022 Acura Mdx with identical failures earlier the same day, suggesting this may be a widespread defect. The dealer found no recalls and attributed the issue to a steering angle sensor malfunction. Given the severity and the risk of injury or death, I am reporting this to NHTSA. Request: NHTSA investigation into whether this is part of a broader safety defect affecting 2022 Acura Mdx models, and whether a recall or manufacturer corrective action is warranted.

While driving the vehicle and while it was in motion, I received a wave of faults. The power steering, lane departure, brake system, brake hold system, vehicle stability assist, hill start assist, trailer stability, and adaptive cruise control all failed. Consequently, the steering wheel locked completely while the car was in motion. I couldn’t steer at all, and the car was in motion! I informed american Honda and the dealer, who informed me that “they had never heard of such a problem”, and that they were “unable to duplicate the issue” when the tow truck brought it into the shop.

Driving when all electronic lights flashed. Rakes steering driver assist lift and towing. Said see dealer reset after I waited at gas station for 30 min power steering worked but was hard to control car.

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.

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.
