Adaptive Cruise Control Problems of Acura RDX

While driving today around 30 mph using cruise control the display suddenly changed from showing a vehicle icon on the hud and dashboard display to a black box with a white line around it with the words in white "cruise mode" and disabled my cruise control operation while I was driving. This action almost resulted in a rear end collision with the vehicle in front of me as I was barely able to stop the vehicle before hitting the rear of the car in front of me. There was no warning no message that the function was being disabled. It just suddenly happened. I have contacted multiple dealers on this, contacted Acura emergency services and roadside assistance. No one has ever heard of this happening and have no idea of the cause. Acura client relations is closed on the weekends and has no hotline on the weekend for reporting safety issues. I can't even get any constructive feedback as to if the car is currently safe to drive without using the cruise control. I have scheduled an appointment with Acura of fremont service on Monday at 2:30pm pdt. This may be a flawed vehicle update that was pushed onto the vehicle while driving as I have run in car diagnostics and everything that should be normal in green seems to be. In my opinion this should be a high priority as it can lead to collisions.

While driving, all adas and emmision system malfunctioned and went offline (errors appear on main control panel and these features were no longer working). Fortunately, the car was otherwise still drivable without these features. It was brought to a local Acura dealer and they performed a software update which fixed the problem (at least so far after a week of driving).

The vehicles adaptive cruise control is unreliable. Guidance system goes haywire and cannot stay on track to destination. Carplay becomes inoperable. Have had tameron eastern shore Honda who sold car to me check problem on multiple occasions and they cannot find problem.

The contact owned a 2017 Acura Rdx. The contact stated that while she was driving, the adaptive cruise control was set to 25 mph, when she depressed on the brake pedal at the stoplight, but the brakes failed to respond, which resulted in her vehicle rear-ending six other vehicles. The air bags deployed. Medical attention was required as the contact and her husband were taken to the hospital for the injuries sustained. The contact believed one of the driver, was also taken to the hospital, but she was uncertain. A police report was filed. The vehicle was towed to a towing lot and the contact deemed the vehicle totaled. The contact stated that after reviewing the vehicle's manual, she learned that the adaptive cruise control has limited braking capabilities and would automatically cancel if the speed drops below 22 mph. The dealer and manufacturer were not made aware of the failure. The failure mileage was 18,000.

While using the cruise control, vehicle will automatically slam on the brakes without reason. This typically occurs on highway where vehicle will automatically brake reducing speed dramatically. Vehicle will go from 70mph to 55 mph in a few seconds causing the vehicles behind to have to brake fast to avoid collision. Acura has worked on vehicle 4 times and claims they cannot fix the system. I was told to hold my foot over the accelerator to increase speed when this happens. They also told me that they are very aware of this problem but offered no correction for this unsafe condition. It has happened at least 100 times. Vehicle is 4 years old with 7,000 miles.

Purchased my 2021 in November of 2020. Two weeks after, I was driving with adaptive cruise on at 65 mph on a freeway. 100 yds ahead I could see a diesel going slower than I, so I looked and saw no one coming at all, so I moved over to the passing lane. I got 5 feet into the lane and the car slammed on its brakes, on its own!!! thank god no one was behind me or I might have died!! I reported this to Acura within 1 week, and then reported it to dot the next week. I own one of the first 2021 s made, so I didn’t see a lot of feedback. Now after a year and a half I get on the dot website and see many complaints like mine. This has happens to me maybe once every 3 weeks. Why has the dot done nothing about this??!!! also the dot says there are no recalls on my car but if you go to the Acura website it says my car is under recall for a driveshaft problem, of which I never received a notice. Why does the dot exist??.
