Cruise Control Problems of Acura RDX

- 2020 Acura Rdx aspec purchased apr2020 new - ~2,800 miles when incident occurred on sat, 4jul2020 - was traveling on I-10 west at ~70 to 75 mph - attempted to pass a vehicle (on the left) when car lost all ability to accelerate and orange engine light began to blink in lower left corner of dashboard - I was pushing accelerator to the floor but no acceleration, no engine revving - vehicle slowed down to ~20 mph by the time I was able was able to get over to shoulder safely - turned car off waited ~30 seconds turned car back on and car appeared to function properly - I reported issue to Acura dealership - service rep advised that this is a known issue, but service manager said he knew nothing about this issue - I researched issue and discovered that my vehicle appears to have experienced "limp mode" - as have many other 2019 and 2020 Acura Rdx models - at time of incident was using adaptive cruise control with one bar spacing between vehicles, start/stop was on, comfort mode, always use premium (93) fuel, gas tank was ~1/2 full, weather was clear ~90 degrees - after restarting car realized that had changed to sport+ mode - at this point, I no longer trust the safety of this vehicle - this could have caused a catastrophic accident had there been a fast moving vehicle (e. G. 18 wheeler) behind me - up to and including death - vehicle is currently at dealership for analysis.

Lkas system is dangerous - will pull to the right then shift to left dramatically and then overshoot markers. Will take you off the road, car will not stay in the correct lane. Does not recognize double yellow lines and cuts right across them, sometimes unexpectedly. Pays no attention to them driving on a 8 lane highway, in the fast lane with cruise control on. I am passing a car/truck going slower in the next lane to my right. All of a sudden, the car just hits the brakes and sounds an alarm. Very dangerous, can be hit from behind due to sudden unexpected braking. My car was not close to the other vehicle only approaching it. I've had the same thing happen when I'm moving to an exit lane with the blinker on. When approaching an entrance onto the interstate, the car sees the guard rail as a hazard and again, brakes hard while flashing the warning light. E car, I have reported it to the service group but as always the problems occur randomly I've also had it happen with a loner, a 2020 model. When approaching an entrance onto the interstate, the car sees the guard rail as a hazard and again, brakes hard while flashing the warning light. Stupid! the turn signal is in use. These are vehicle hazards caused by the so called, enhanced safety features, but which, in fact, create a situation that is dangerous. If anyone else drives the car, I have to spend time educating them of the �problems� they may encounter driving the car. I have reported it to the service group but as always the problems occur randomly and never when the car is in for service. I've also had it happen with a loner, a 2020 model.

I was driving on a highway with the automatic cruise control (acc) enabled and set at 68 mph. Without touching the pedal or controls, the cruise speed setting suddenly jumped to 90 mph and my car rapidly accelerated to reach that speed. Fortunately, there was no one in front of me and I was able to take control of the car and disable cruise control.

Uncontrolled acceleration in the two episodes that I described to the dealer when I brought the car in for service, I was unaware of the acc feature. I had not yet, and have still not, used any cruise control or acc. #1. I was in a parking lot of a costco. I had just started the car, backed out of a spot, and proceeded to the end of the row, where I would now turn left onto the main 2 lane (1 in each direction) feeder into the parking lot, from the public street. There was some traffic coming from the left and some coming from the right, but there was room to merge and turn left onto this feeder, to exit the lot. As I began to turn the wheel and slowly press on the gas pedal, the car began to accelerate � at a much faster rate that was safe in the parking lot, as there were other rows still feeding into this exit drive. I slammed on the brakes, and the car stopped. #2. I had been driving on the freeway for at least 20 minutes and then exited the freeway to go home. As I neared the left turn to enter our street, I stopped to let oncoming traffic clear, and then I released the foot brake and began to turn and slowly press on the gas pedal. Again, the car began to accelerate at a faster rate than was safe onto our narrow street and up a small hill with limited visibility. Again, I slammed on the brakes, and the car stopped � thankfully out of the oncoming traffic that I had just crossed. In both scenarios, I had not been using any cruise control or acc. It appears, but is not certain, that somehow the acc was active, and when I stopped to turn left, and then accelerated, the acc reengaged and accelerated far more than was safe. I would also point out that 1. In both cases, I was turning left when the acceleration occurred, and 2. In the episode at the costco, I had only just started my car, backed it out of a space, and then proceeded to a turn.
