2019 Acura RDX Electrical System Problems

Vehicle: 2019 Acura RDX (Technology Package) I am reporting a serious safety issue involving sudden loss of engine power while driving. On March 14, 2026, I filled my gas tank before traveling approximately 1.5 hours out of town. The vehicle operated normally that day. The following morning, during snowy and icy conditions, while accelerating in traffic, the vehicle suddenly lost power and stalled. Multiple warning lights illuminated on the dashboard (“Christmas tree” effect), and the steering became very stiff, making it difficult to safely maneuver the vehicle out of traffic. I was able to restart the vehicle, but warning lights remained on. The next day, while driving on the highway under normal conditions, the same issue occurred again. While accelerating, the vehicle suddenly lost power and stalled in traffic, creating a dangerous situation. In response, the fuel pump inside the gas tank was replaced; however, the problem persists. The vehicle continues to display warning lights and still loses power when accelerating. I contacted an Acura dealership after seeing reports of a fuel pump recall for similar vehicles, but I was told my VIN was not included. Despite this, the symptoms match known fuel pump-related issues. This defect poses a serious safety risk, especially when driving at highway speeds or in traffic, as sudden loss of power and steering assist can lead to a crash. No injuries have occurred yet, but the issue is ongoing and unresolved. I am requesting investigation into this issue as a potential safety defect.

Component Failure & Inspection: The rear windshield glass spontaneously imploded/shattered. This is a documented manufacturing defect involving the rear defroster grid, as detailed in Acura Technical Service Bulletin (TSB) 22-014. The vehicle and the shattered glass are currently available for inspection. Safety Risk: The glass shattered while the vehicle was occupied, spraying shards of tempered glass into the cabin. This posed an immediate risk of laceration and eye injury to the occupants, as well as a significant distraction/startle hazard that could have resulted in a collision if the vehicle were in motion. Confirmation: The failure was inspected and confirmed by McGrath Acura of Westmont on February 27, 2026. The dealership acknowledged the existence of TSB 22-014 and the defect in the defroster grid but has not yet provided a full remedy. Manufacturer Inspection: The vehicle is an Acura Precision Certified unit. A formal case has been opened with Acura Client Relations (Case #16209033), and photos of the failure have been provided to them. Warning Symptoms: There were no warning lamps or symptoms prior to the failure. The glass imploded suddenly and without external impact while the vehicle was stationary.

Vehicle was stolen within 15 minutes due to a weak door lock cylinder on the driver's door. Once the robber was inside they used a scanner yo bypass the weak security system and erased all key fobs

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.

The contact owns a 2019 Acura RDX. The contact stated while driving at an undisclosed speed, the contact attempted to use the horn however, the horn was inoperable. The contact stated that while attempting to engage the horn, the horn failed to function properly or make a sound. The vehicle was taken to the dealer, where it was diagnosed that there were internal parts located in parts of the horn that needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 63,220.

The auto-stop feature on my 2019 Acura RDX has resulted in my car abruptly shutting down twice now -- today it happened when I slowed to a stop at an intersection. Basically, rather than just shutting the engine off while idling, it shuts of the electrical (dashboard and infotainment -- all systems) and engine and then immediately restarts with the car in Park. There was no warning sound or light prior to the car turning off and restarting. Obviously, it is very dangerous for a car to turn off unexpectedly, and I'm thankful that I was braking to a stop at a red light and had time for the engine to turn back on, and to put car back in Drive.

Problem with rear back mirror defects after so long my back window shattered with no reason

Back up camera system failure

This morning I awoke to another shattered rear windshield. I had the exact same thing happen in January of this year. This is my second out of cost rear windshield replacement due to the known problem Acura has failed to address. I have spent over 1,000 dollars on replacement glass in addition to my car being in the shop for 3 months waiting for a fuel pump. This is ridiculous, and something needs to be done.

I was driving on the highway and it was raining. I tried to pass another car so I started to accelerate. But during my attempt to accelerate, my 2019 Acura RDX would not respond to throttle response. So I slowly started to loose speed the car. The engine warning light started to flash and the car came to a stop on a dangerous road construction area with no medians. I had to turn on my hazards and wait ON THE ROAD at night. I quickly turned off the engine and tried to turn the engine on again. When I turned the engine on it no error codes were shown and the check engine light was gone. I started to drive again and was able to get to a service road. After a while I decided to try to keep driving so I could get home and when I was merging into the highway, it happened again. The same situation, I was accelerating when my engine decided to stop accelerating and flash the check engine light (it didn’t stall but it wouldn’t respond to throttle response). I stopped on the side of the road and turned the engine off before turning it on again. Again the check engine light was not on, and the car acted like nothing happened. It seems like accelerating to higher speed in the rain is a huge safety issue…

On 02/25/2023 our car abruptly stalled on us while driving without any warning in a remote area out of state over 3 hours away from our residence at night with temperatures below freezing with a minor in the car. We were lucky it happened on a back road and not on highway with hi velocity just an hour earlier because this would have killed us. The car came to a complete stall in the middle of the road, the red battery sign came on and the car would not start. We had a very poor cell phone reception, it took us over 3 hours to get a tow track, by the time the truck arrived we were shivering from cold. The car is impossible to put in neutral while in full stall that makes removing car from the road and towing near impossible. The car got towed to the nearest Acura repair center in PA. We were left with no car with a minor in the middle of the night in the cold out of state with very limited financial resources. As of now the car is still at the repair shop in PA, we are back in Maryland without any vehicle. The repair shop told us that there is no fuel pressure and it is likely fuel pump failure, that has already been reported and recalled on other Acura RDX 2019, but for some reason is not associated with our VIN. This is a major safety concern with a faulty part on a 4 years old car that could have potentially killed us and now is putting unimaginable financial, logistical and emotional hardship on us being left without a vehicle out of state and absolutely no timeline on when this very costly repair will be done due to unavailability of the part. Please issue a recall on this VIN ASAP before somebody will get hurt. It seems to be problem with many Acura RDX 2019 cars and is calling for much larger recalls then previously issued NHTSA recalls: 21V-215 FAM 2019-20 RDX Fuel Pump Motor Safety Recall Expansion and 20V-314 S7D2019 /RDX Fuel Pump Motor Safety Recall. This same exact fuel pump failure is reported all over the internet in forums and RDX 2019 reviews.

Once again, 3 weeks after the first time it happened, my 2019 ACURA RDX lost ALL power and I had to drift to the side of the road. This occurred on the Baldwin Beach Express and luckily there is not a lot of traffic this time of year so I could get on the shoulder. Car would not restart, all lights around the speedometer had come on. I had to have it towed to the Acura dealership in Mobile where it was towed the first time when this happened. At that time the told me they could not duplicate the problem. Three weeks later it has happened again . The tow truck driver tried to start the car and said " you're not getting any fuel" and asked if the fuel pump had been checked. Supposedly it has been replaced when it was first recalled. Could it be another faulty fuel pump? My question....how dangerous would this be if this happened in the I-10 Mobile tunnel?????? The first time it happened I tried to call Acura but the complaint department is not open on Sundays. This time it happened on a Friday and I was able to file my complaint. Will I get a response to this event now that it has happened a second time?

While driving on interstate 65 headed towards Mobile, Al. My 2019 Acura RDX lost ALL power. Every light surrounding the speedometer was lighted. No power, nothing.. was able to coast from the right hand lane to the shoulder of the interstate. . No power steering and I was moving slower and slower because I was on a hill. Frightening to say the least. If I had been in the left hand lane I’m not sure I could have made it to the shoulder. And if a truck had been behind me an unable to change lanes I would have been smashed. Car towed to dealership.

On November 26, 2022 RDX rear glass shattered while parked. This was reported to ACURA to find out if this is a known defect. Acura replied that they don’t have a recall on this problem. Coincidentally, few days after glass was replaced (insurance) the remote start failed due to “open trunk, doors or hood”. Acura dealer replace defective trunk switch. On a few other occasion the infotainment screen will go blank and then turned ON and stay ON while vehicle is off. Battery died several times while this happened. Last occasion was Jan 15, 2023. Again, Acura was called and didn’t have a recall/repair solution. Battery was disconnected and screen resumed operation!

Was driving on the interstate with slight rain and trying to accelerate but then the check engine light started flashing and the car would not accelerate. Speed on the interstate is 70mph, but the car immediately dropped down to 35mph. Traffic behind me had to slow down to avoid an accident as I had to move the car to the side of the road. Restarted the car and the check engine light disappeared.

I was driving and all of a sudden the car started to slow down and wouldn’t accelerate. After a couple pushes on the pedal it just completely shut off. Every mechanical light was on or flashing. I was in the middle of the road terrified but was able to steer over to the side of the street. I called 911. 2 gentlemen tried helping push it out of the way of traffic but we couldn’t get the car in neutral. I was able to get a tow to the dealership and they claimed nothing was wrong. My safety and other drivers were out at risk because I was blocking an entrance lane to a busy shopping center and a police officer had to park behind me. There was no warning, it came out of nowhere. I know there is a class action suit regarding this issue. I refuse to drive the car.

THE ABOVE MENTIONED VEHICLE WAS LEASED IN MARCH 2019. I HAVE RECENTLY EXPERIENCED ISSUES WITH THE INFOTAINMENT SYSTEM THAT COMES STANDARD WITH MY VEHICLE. THE SCREEN IS GOING BLACK AND NOT RESPONDING WHILE THE VEHICLE IS IN MOTION ON A BRIDGE. THIS IS CAUSING MY BLUETOOTH, BLINDSPOT ASSIST, NAVIGATION, AND ENTIRE COMPUTER SYSTEM TO MALFUNCTION. I AM ALSO HAVING ISSUES WITH THE VEHICLE STARTING. IT WAS AT ONE POINT I WAS TOLD TO PLACE MY KEY NEAR THE START BUTTON IN ORDER FOR THE VEHICLE TO START. I WAS INFORMED BY DANIEL FLORES OF ACURA OF WAPPINGER FALLS THAT THEY ARE AWARE OF THE ISSUE BUT THEY HAVE NO IDEA WHEN THE ISSUE WILL BE RESOLVED. I AM AFRAID THAT I WILL BE PLACED IN A SITUATION WHERE MY VEHICLE WILL NOT START OR CAUSE A SAFETY ISSUE FOR MYSELF OR A PEDESTRIAN. MY VEHICLE IS LESS THAN A YEAR OLD AND I HAVE I INVESTED MORE THAN $10000 IN IT. THE ONLY WAY FOR ME TO GET OUT OF IT IS TO SPEND AN ADDITIONAL $133.00 A MONTH (WHICH I DO NOT HAVE) AND CHANGE THE VEHICLE OUT TODAY!!!. I AM LOOKING FOR HELP. MY HUSBAND RECENTLY HAD A 2013 NISSAN ROGUE CATCH ON FIRE IN MY DRIVEWAY JUST UNDER MY BEDROOM WINDOW. I AM AFRAID THAT SOMETHING LIKE THIS MAY OCCUR AGAIN.
