2020 Acura MDX Speed Control & Cruise Problems

I start getting every kind of warning on my dashboard - Collision mitigation system problem -Auto Crues Control Problem -Brake system Light on - The Car apply brake on the miidle of street/Highway

I was driving on a normal sunny day when every light on my dashboard came on. I initially panicked thinking my car was going to shutoff while I was driving it. This is in conjunction with the car stalling out when the auto shutoff feature malfunctions. After researching the issue, I realized the safety camera was no longer working and a major concern. A malfunctioning front camera can prevent the vehicle from automatically braking or maintaining lanes, hence increasing the risk of collision. I am requesting that NHTSA investigate the front multi-purpose camera system on the 2020 Acura MDX for potential defect and safety hazard.

1. The car accelerates by intself. The accelaration is like "hiccups". When reversing and changing to D gear, it takes longer than usual for the accelarion to take effect. Yes, car is available for inspections 2. It is dangerus because it gets the hiccups even at high speeds. If it is a serious egine problem, which seems like it is, could cause an accident. 3. The car was taken to the dealership for 3 recalls but it got worse after the recalls were fixed. Supposedly the recalls were supposed to fix the issues. We have not taken it back yet. 4. There is no lights or warnings when it does it.

MALFUNCTION: ROAD MITIGATION SYSTEM FAILED (RDM), LANE KEEPING ASSIST SYSTEM (LKAS) FAILED, and CRUSE CONTROL FAILED, after investigating the issue this is happening with multiple vehicles. SAFETY: YES, these all failed at the same time, poses significant safety issues for the diver, passengers, and other drivers due to nature of failure. CONFORMATION: at this time no inspection of the vehicle has transpired. NO OTHER WANING LAMPS OR MESSAGES, prior to suddenly showing up today 6/18/25

upon turning right, the car lost power, degraded acceleration as if someone is holding and pulling the car to move forward. The traffic behind me expected me to cathup with the speed on the road but due to loss of power and engine hesitation i got honked and was luck to avoid a crash from behind on a busy road. Acura dealership in Dallas dont have parts since a very long time. They have pleant of new cars to sell but not repair.

I stopped at a stop sign and the car went into N without me changing anything. The car wouldnt go back to D or P mode even when I pressed the buttons. I had to turn off the car and turn it on again to make it function properlty. This happened twice within 5 mins.

Problem started 1 month ago. As I approached the round about I am at very slow speed,and for no action on my part, my MDX accelerates! Fortunately it has only happened as my vehicle is coasting or I am applying the break slowly. This is happening more and more. It has over 20K miles on it.

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.
