2019 Acura Rdx

While driving in the rain, after an hour long drive home from Philadelphia back to Reading, taking [XXX] and [XXX], I accelerated my vehicle while going around 50 mph and immediately was faced with a blinking check engine light and lost the ability to accelerate. My Acura essentially went into, what others call, limp mode while in sport mode. I filled my car with 93 gas around 20 minutes before this. After losing acceleration, I pulled over on the highway and the check engine light disappeared. After which, I still was unable to accelerate after leaving the car in park. After I turned the car off and turned the car back on maybe 30 seconds later, I was then able to accelerate and found no issues afterwards.

On July 24, 2022, while driving from Champaign-Urbana, Illinois back to our home in Lisle, IL, in a heavy rainstorm, our RDX suddenly started flashing the engine light and lost power on Interstate 57. We were fortunate to be able to maneuver it to the side of the road, and off the nearby ramp at Bradley, IL. We ‘googled’ the circumstances on our iphone, to learn that this is considered a serious, potentially life-threatening situation, and that Acura recommended immediate Service Bulletin 20-053, dated May 25, 2021, states the symptom as “The MIL is flashing with loss of power.” It indicates “Corrective Action” for the RDX as “Update the PGM-FI and replace the intercooler, the intercooler outlet pipe assembly and the intercooler outlet hose.” Affected vehicles include “ALL” 2019-2020 RDX models.” Despite the Service Bulletin that was issued, many RDX owners, noted the same response from their local Acura dealer. They note that the dealers “played dumb,” claim they could not locate a Service Code, nor “replicate the conditions and response” in the shop…. precisely my experience! In fact, the Service Receipt, indicates the car was driven less than one mile, hardly sufficient to replicate conditions. Acura Client Relations has refused to assist. I contacted the CEO Jon Ikeda but his office has not responded. I fear driving the car in wet conditions.

Vehicle went into limp mode while I was accelerating up to speed onto a highway crossing lanes and driving uphill. All acceleration stopped, and the vehicle quickly decelerated due to being on a steep hill. It was not raining at the time. I had moved into the leftmost lane, and luckily there was a left shoulder to pull the car onto. The check engine light came on and was flashing. I turned the car off and back on, and it started. There could have been a very bad accident.

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.

1. TWICE WHILE DRIVING, WARNING LIGHTS FLASH "APPROACHING OBJECT" WHEN THERE IS NOTHING AROUND THE VEHICLE, SPEED ABOUT 20MPH, EMPTY, RURAL ROAD, NO BAD WEATHER, 8AM IN THE MORNING. 2. WHEN TRYING TO START THE VEHICLE, THE ENTIRE CAR SHUDDERED AND WOULD NOT TURN OVER. RE-TRIED AND THE CAR STARTED. CAR WAS STATIONARY IN A GARAGE. 3. WHILE DRIVING ABOUT 60 MPH, HWY 29 NORTH IN DANVILLE, VA, THE ENTIRE CAR SHUDDERED FOR 2-3 SECONDS LOSING POWER. THE VEHICLE DIDN'T SHUTOFF AND I WAS ABLE TO RESUME SAFE DRIVING. NO INCLEMENT WEATHER AT THE TIME. 4. WHILE AT A STOP LIGHT IN VIRGINIA, THE VEHICLE LURCHED FORWARD (ACCELERATED ON IT'S OWN) WHEN I TOOK MY FOOT OFF THE GAS PEDAL AND I HAD TO SLAM ON BRAKES. I WAS ABLE TO RESUME SAFE OPERATION AFTERWARDS. NO INCLEMENT WEATHER. NORMAL BUSY TRAFFIC IN NORTHERN VA. REFER TO REPAIR ORDER # 6138673, 7/31/2020, CHEVY CHASE ACURA, BETHESDA, MD FOR ADDITIONAL INFO.

I HAD THE CRUISE AND LKAS ON AND SET TO 75. I MANUALLY CANCELLED CRUISE AND BEGAN TO INCREASE SPEED TO GET INTO ANOTHER LANE. WHILE PRESSING THE ACCELERATOR, MY RDX COASTED AND DECELERATED INSTEAD OF GAINING SPEED. I MADE AN EMERGENCY STOP (AS SAFE AS POSSIBLE) AND PUT THE RDX IN PARK. SHIFTED INTO DRIVE AGAIN AND THE VEHICLE STARTED MOVING. WHEN PRESSING THE ACCELERATOR, SPEED WOULD NOT INCREASE AND I COULD HEAR MY RPMS GOING UP BUT YOU WOULDN'T KNOW IT BY LOOKING AT THE GAUGE. KEEP IN MIND THE MALFUNCTION LIGHT IS BLINKING, SOLID, BLINKING, AND THEN STOPS ALTOGETHER (NEVER HAVE SAW THIS ORANGE LIGHT UNTIL THIS HAPPENED). I TURNED THE VEHICLE OFF AND BACK ON, AND DROVE AWAY LIKE IT NEVER HAPPENED AND THE LIGHT WAS GONE.
