I-??ve had this happen 4 times now with my 2019 RDX. The latest Is on 12/10/23. Low speed braking and the tac revels to over 5000. Vehicle lurches forward with both feet on the brake peddle nearly hit a car broadside that was moving perpendicular to me., Three times under warranty to the dealer who could find anything. They even had the factory rep, in who after keeping the car for 5 days replaced an abs sensor. Now that the warranty is up they want $120 an hour to diagnose the problem that they couldn-??t before.. But this is a dangerous vehicle that.I-??m scared to drive. After reviewing several forums this appears to be a know problem Acura won-??t address.

Transmission intermittently gets stuck in a gear while driving and will not shift until car is powered off and on again. Brake system, LKA, power steering, vehicle stability/traction control, hill assist, cruise control, collision mitigation, and road departure mitigation intermittently stop working and error. Infotainment and audio intermittently error or get stuck on after powering off vehicle. Trunk randomly opens when no one is in range of the vehicle. Horn randomly sounds for approximately 30 seconds on hot days after vehicle is stopped. Engine cylinder heads, transmission, and horns have been replaced without resolution. MOST bus system has been replaced twice without resolution. All issues have been recorded on video and documented with the local Acura dealer and Acura Client Relations, but neither has been willing to help reach a resolution.

My car has been shaking on acceleration but no engine light or any warning popped up. When I called an Acura dealership, they said they would have trouble diagnosing the problem without a light on. A few days later, while accelerating on the highway, my car started shaking violently and lost power. The engine light started flashing. I could have gotten into an accident because I could no longer accelerate on the highway. I had to slowly pull off to a safe stop. This could have been a dangerous and life-threatening situation. Someone could have crashed into me behind me and I could not quickly get into a safe area. I brought it to an Acura dealership and they could not find anything. The engine light had turned off. Though, when I took the car again, the car was still shaking on acceleration. I was afraid to drive at normal speeds since it is extremely safe. I took it to another personal mechanic and he was able to reproduce the problem. He saw there is a service bulletin out for just this problem. The possible cause is -??humid air within the intake tract May condense and accumulate excessive moisture during steady driving.-?? I would have to replace the intercooler system and get the PGM-Fl software updated. This is a safety issue, and Acura has not released any recalls on this. The dealerships are also saying it will not be covered by warranty for me.

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 -€œThe MIL is flashing with loss of power.-€ It indicates -€œCorrective Action-€ for the RDX as -€œUpdate the PGM-FI and replace the intercooler, the intercooler outlet pipe assembly and the intercooler outlet hose.-€ Affected vehicles include -€œALL-€ 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 -€œplayed dumb, -€ claim they could not locate a Service Code, nor -€œreplicate 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.

On 9/22/22 travelling on I-290 near Boylston, MA I was passing a large tractor trailer in the far left lane going up a hill. It was and had been raining very hard for at least the previous hour. When I stepped on the accelerator to increase speed, the car suddenly decelerated to about 20 mph and the check engine light began flashing. I was able cross all three lanes in very heavy traffic to the shoulder. I then slowly made my way off the interstate to a gas station right beyond the exit. My passengers and I were very concerned about the suddenness and the abrupt reduction in speed on an extremely busy roadway. A call to the nearest Acura dealer service department confirmed he had seen nearly the same symptoms the prior week under similar road conditions and the same model car as mine. He found no codes on the other car. I also notified Acura customer service who confirmed the existence of a Service Bulletin on precisely this issue (flashing light with loss of power).

on 2/3/22, after only 12 hours of owning the vehicle, I merged onto 287 South and upon speeding up and merging into the center lane, I lost all acceleration and my dash lit up like a Christmas Tree. An 18 wheeler was coming behind me in the middle lane at 65 mph while my car slowed down to 25 mph. I was thankfully able to get over to the side of the road without being hurt or even killed. Upon bringing it into the dealer, the codes showed that it was a bad engine coil and spark plug. This was repaired under warranty. Fast forward to 5/16/22, I exited the highway, came to a complete stop at a red light. Upon the light turning green, I went to accelerate and limp mode activated again. I have video of the incident and dealership is unable to find any issues with the vehicle. Both times it was either raining or had just stopped. I have asked that the Intercooler be replaced as part of Bulletin 20-053 however the dealership states my vehicle is not part of this bulletin although it lists the model and year. This is a serious problem that requires a recall. I hope Acura is not waiting for someone to get hurt before they take action!

I was driving for approx. 3 hours on the interstate and exited to return home. After stopping at the red light my car would not excel. The rpm where moving up to 4 plus but the car wouldn-€™t go over 20 miles an hour when pressing the excelerator. No warning lights came on but I pulled over and turned the car off trying to decide what to do. I couldn-€™t get back on the road driving 20 miles an hour because it wouldn-€™t be safe. I decided to restarted the car then I drove 2 miles home without incident. I will take the car to the dealer after the holidays because I-€™m scared to drive it. I bought the car with 25,000 miles and it now has 32,000 miles on it.

My 2019 Acura RDX suddenly lost power while accelerating on two occasions this year. Both times it occurred in clear weather with temperatures around 80 degrees. The first time it happened was on 7/15/2021 when I was accelerating onto a US Highway. The second time was on 10/4/2021 when accelerating from a stoplight. Both times I had to coast to the side of the road due to loss of power. I was able to restore power by restarting the engine. Please investigate since loss of acceleration can lead to crashes. For example, it can be deadly if it occurs while passing on a 2-lane road or making a left turn in front of oncoming traffic. Thanks.

On 7/24/2021 around 6.30pm, the transmission on my RDX suddenly failed. The problem happened when I attempted to accelerated when entering a highway. I temporarily fixed the problem by turning engine off and re-starting.

Three hours into a four hour road trip, we had been driving in the rain when needed to overtake a slow car in the right lane. Went to accelerate when car lost all power and a check engine light came on flash. Pulled over to the emergency lane and turned flasher on. Car had to be glided into the lane as there was little to no power when using the gas. Thankfully we had not passed the vehicle yet when we lost power and the car behind us had enough room to slow down. After turning the car off and on again check engine light went off and car had normal power again. We were able to drive it for the next hour without further issue. We will be bringing this into the dealer to have it inspected. Currently car has only around 18k miles on it and have never had this issue before.

On 4/17/2021 my wife and I were traveling form Florida to California, while traveling on I -49N in Louisiana I went to accelerate around a slower car and when I pushed the gas our car lost power and the check engine light started flashing causing us to suddenly slow down and almost being stuck by other automobiles in traffic. I was able to make it over to the shoulder of the interstate and shut off our SUV for about ten minutes and the issue was gone.

This is the second complaint for this vehicle, the previous complaint was assigned NHTSA id number: 11277657. Similar to the incident that was previously reported, while driving on a highway at a high rate of speed, attempting to pass another vehicle, the car went into limp mode, lost acceleration, steering became difficult, and the check engine light came on. Luckily, we were able to safely get the car into the right hand lane and pull off into the shoulder. We turned the vehicle off and when we turned it back on the vehicle operated normally. As with the previous incident, this occurred in the rain. The car was brought to the dealership and, as with the previous incident, we were told they could not duplicate this issue and the vehicle was returned to us. We were told that if the issue occurs again to bring the vehicle back to the dealership. As stated in my previous complaint, this is an extremely dangerous malfunction that could result in a serious accident. This time my two children were in the car. What is it going to take for Acura to find an acceptable resolution to this problem" how many of these malfunctioning vehicles are on the road??"

While accelerating through 50mph the car suddenly stops developing power and begins to coast down to a stop, regardless of gas pedal input. The vehicles 'malfunction indicator lamp', 'electric power steering (eps) system indicator', 'vehicle stability assist (vsa) system indicator', 'road departure mitigation (rdm) indicator', 'collision mitigation braking system (cmbs) indicator', and 'brake system' light illiminate simultaneeously. The center display rotates through these problems, advises to avoid heavy acceleration and high speed, and advises to see the dealership. This happened while merging into a lane on the highway and could have easily killed me. This car must be recalled. This car has been maintained on all required inspections, is run on 91oct gas, and was just in a certified Acura dealership less than a month ago for an unrelated issue.

Driving for 15 minutes engine stopped while going up a very busy bridge on I-10 - started shaking and flashing no brakes no steering contact dealer. Coasted to construction area on top of bridge as to not be hit by 18 wheelers. The vehicle was out of warranty by 1200 miles... that's ridiculous

Transmission does not down shift appropriately when slowing or traveling a low speed and the need for fast acceleration is needed. There is about a 3 second delay before any throttle response or acceleration. Car is stuck in 5 or 6 gear and going 10-15 miles per hour and no acceleration despite gas peddle pressed to the floor. Highly dangerous delay in acceleration response like when cross traffic. This will get people killed. Dealer says is working as designed. But it a very dangerous design flaw then. I can slow from 40 mph to 10 mph and then apply full acceleration and there is no response from the vehicle for 3 second. Very repeatable. No acceleration despite gas peddle pressed to the floor.

We turned onto the on-ramp of I40 West in Arkansas at exit 58 heading West. I accelerated to get up to speed to merge onto the highway. When I reached 70mph the car stopped acceleration and very rapidly slowed to 20mph in front of multiple cars and semi trucks. I was lucky to have been missed by the traffic behind us and was able to get to the right shoulder. The car would not accelerate past 10-20mph. We limped to the next exit and found a parking lot. I turned the car off and back on and it seemed to be working correctly again. My entire family could have easily been killed! during the incident the check engine light came on and remained on until turning the car off and back on.
