2020 Acura Rdx

On April 18, 2023 driving thru shopping center parking lot, WITHOUT WARNING car suddenly jerked right, accelerated, while brakes, steering wheel, gears locked. Ended crashing thru the wall of a structure. Airbags did NOT deploy but seat belts tightened firmly keeping us from going thru windshield. Episode of "UNINTENDED ACCELERATION" was reported to Honda Motors whose agent, Jason, checked the car 8/1/23 and found no defect. We had driven the car for almost 49,000 miles without incident yet, their agent drove it for LESS than 10 miles and concluded NOTHING WRONG with the car. Twelve days later while stopped at a red light, dashboard lights suddenly flashed and engine came to a complete STOP. DEAD. Conclusion was damaged sensor to gas tank since husband had run over tanker truck tire debris on fwy earlier in the day. Point is, this 2020 Acura RDX with <50K miles has had TWO MAJOR INCIDENTS : UNINTENDED ACCELERATION and UNINTENDED DECELERATION. Feel betrayed by Honda Motors Corp at conducting a superficial, inadequate inspection for the defects mentioned and fear for our safety and those of others we share on the road. There's a class action lawsuit in Florida for similar complaints but we live in California and have been unable to procure legal representation.....apparently, not cost effective. My driving record is clean.

upon entering the cross driveway at a mall parking lot, car suddenly veered right, accelerating & unresponsive to stepping on brakes pedal, steering wheel locked, gear buttons did not respond, seat belts tightened, but air bags DID NOT deploy. Speed was slowed when car ran over a large rock and crashed into the wall of small store front. I, the driver, have not been in any accidents, had not taken any medication of any sort.

On September 6, 2022, at 7:45 AM I was traveling from my home to work in my 2020 Acura RDX. As I was merging on to an interstate in heavy, high-speed traffic, my RDX suddenly lost power and started to decelerate with absolutely no warning at all as high-speed traffic was approaching from behind. My vehicle decelerated to a speed of about 20mph on an interstate in the midst of heavy, high-speed traffic. The malfunction indication light began flashing in the instrument panel. I was able to drive at slow speed of about 15-20 mph, with 4-way lights flashing, until I could exit the interstate. I turned the car off for a few minutes and then was able to proceed. This created an extremely dangerous situation.

11/6/21: Mid way home from a trip from Washington to Connecticut on the New Jersey turnpike in the left-hand lane the car lost all ability to accelerate. Concurrently the engine like came on and multiple warning signals came on regarding traction control, breaking, and steering. One can imagine how unsettling that could be but at that moment. Being in the left lane it was apparent I needed to get off the road. With cars traveling at 65+ mph and my car decelerating continuously changing lanes was nearly catastrophic and the last lane I needed to move over to nearly resulted in a multi car accident 11/8/2021 I was contacted by the service manager at the towed to acura dealer. They informed me that the evaluation determined a need for an “intercooler" This breakdown of my car with less than 20,000 miles on it was under warranty . More importantly, my understanding of this problem is that the car is engineered to power down under these circumstances to protect the engine and or transmission. I would have imagined that when a warning like comes on it would not result in an instantaneous power down action. Put quite simply it appears the car was more interested in protecting itself than the occupants. This is egregious. Acura has failed to address my concern or help now about 1 month out

Last week I was driving the 2020 Acura RDX on the Massachusetts Turnpike during very wet weather. Three hours into a planned four hour drive, while accelerating up a hill, the car power cut out. Engine was running, but no oomph. Check engine light, and other lights, flashing on dashboard. Car kept slowing, and there was no place to pull over at that point on the pike (mile 68). Finally, car made it to crest of hill (at that point going 15 miles an hour in the right hand lane and still slowing), and a pull out spot appeared. Pulled over, but a very harrowing experience. Had the car towed to the closest Acura dealer (this was clearly an issue that would be covered by warranty...). They checked out car, and said that they had seen the same problem before, and that fix was to replace the "intercooler kit", which required a part that was on a long back order. Researching other threads, I find that this has happened to others... and that a "fix" can be to turn off the car, and restart after a few minutes. Car seems to drive fine again... In any case, I later moved the car to the dealer where we bought it, and they had the part in stock. Apparently, when it is very wet and a driver accelerates hard, the old part lets some water enter the turbo charger, at which point the car goes into "limp" mode. Apparently, Acura has an outstanding service bulletin on this issue. The reason for my filing... I think that this a recall issue. I love the car, and am glad that it is fixed (at least, I hope it is!), but this is a very bad problem and should not happen. Any questions, please let me know. But I would encourage Acura to do a formal recall...

The contact owned a 2020 Acura RDX. The contact stated while driving approximately 35 mph, the vehicle inadvertently slowed down and without warning a strange noise came from the engine compartment and a sudden jerk to the wheel when the vehicle accelerated without warning up to approximately 100 mph. The contact was able to exit the highway where the vehicle made another strange noise from the engine compartment and the wheel jerked when the vehicle accelerated without warning again which resulted in the contact crashing into a group of 3 vehicles. There were 2 confirmed injuries which were the occupants of the contact's vehicle the driver and front seat passenger. The contact sustained a broken sternum, internal bleeding, decompression of lower back, and swollen right side foot. The contact's son sustained a lumbar fracture and a contusion. The contact does not know if anyone in the other vehicles were injured. A police report was taken and the vehicle was towed to an insurance lot. The vehicle was then towed to a salvaged lot and deemed a total loss. The contact stated she does not know if warning lights were illuminated. The manufacturer was informed of the failure and told the contact that they were unable to assist. The failure mileage was approximately 5,040.

IT WAS MILDLY RAINING AND I WENT TO ACCELLERATE ONTO THE HIGHWAY AND ALL A SUDDEN WITHOUT WARNING THE CAR STARTED TO VIOLENTLY SHAKE AND STUTTER AND THE CAR LOST ALL POWER AND I WAS ALMOST HIT BY ANOTHER CAR BECAUSE I LACKED POWER. THE VEHICLE THEN REFUSED TO ACCELERATE AND I HAD TO DANGEROUSLY GLIDE OFF THE HIGHWAY WITHOUT POWER AND THE VEHICLE HAD TO BE TOWED. EVERY CHECK ENGINE LIGHT CAME ON. I THEN HAD THE VEHICLE FIXED AND THEY SAID IT WAS A PROBLEM WITH AN ENGINE COIL. THREE WEEKS LATER IN THE SAME SITUATION IN THE MILD RAIN THE EXACT SAME PROBLEM HAPPENED AGAIN. I WENT TO GET ON THE HIGHWAY IN A MILD RAIN THE CAR BROKE DOWN THE EXACT SAME WAY. I AM WAITING FOR IT GET DIAGNOSED AGAIN.
