2019 Acura Rdx

While driving on a two lane road at app 60 mph, we accelerated to pass a slower car, Our 2019 Acura RDX lost power and coasted down to about 20 mph and the check engine light was flashing. we had no control over the speed of the vehicle (limp mode), which was very scary and could have caused a serious accident. It was raining earlier but not at the time of the incident. This should be a recall and not just a Acura Service Bulletin 20-053 since it can be life threatening.

Was driving my car home and there was a loud explosion. There were no other cars around me and I couldn’t figure out what happened. I was suddenly aware of the noise of air outside and I could immediately hear stuff flying off my roof. I couldn’t safely pull over for a mile. Found a hole in my front moonroof and it was completely shattered. Had my sunshade not been closed I would have been covered with glass. Reading online lots of other Acura RDX owners have had the same thing happen. This is so dangerous.

I was driving on the highway, clear skies, nothing overhead. Then I heard a loud explosion and slowed down thinking I had a blown tire...but I didn't feel the car to pull to any one side no have difficulty steering. Then I started to hear wind noise in the cabin. When I finally exited the highway I looked up and saw that my sunroof was cracked and had caved in. You can hear the crackling noise. When I touched it pieces literally crumbled and fell into the cloth cover below. I believe the sunroof is defective and may have exploded while I was driving. there is no evidence on the roof that it was hit be road debris (no other spots show any dings or signs of damage).

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.

Vehicle was subject to a relay attack. Perpetrator walked right up to the vehicle and opened the door. My key fobs were far away from the vehicle in the basement. Acura claims there are no known cases of this vehicle hack. However, according to internet sources, Acura/Honda are subject to malicious hacking because their key fobs do not use a "rolling code" system. Other luxury brands have implemented security features which allows the key fob to "sleep" if not moved. See the video of the incident below: https://drive.google.com/file/d/1UiHjcdH-VD0uiHOGj7IbLen9ftJs2q3h/view I want Acura to review the issue and issue a security patch, if deemed appropriate. They are denying everything and maintaining their position that they are aware of "no known issues". Yet the police advised of a criminal ring with 100's of Honda/Acura vehicles stolen this way in NYC, for which the VINS are being scratched off and sold on Craigs list. Please advise if you can assist in this matter. This is a safety issue because when any malicious third party enters a vehicle without permission, they could do anything that would compromise the safety and drivability of the vehicle. Thank you

The contact owns a 2019 Acura RDX. The contact stated that upon exiting a highway and coming to a stop light, the vehicle would not accelerate above 25 MPH without warning. The contact was able to reach his destination and after explaining the failure to a friend; he was informed that his vehicle had gone into limp mode. Upon restart of the vehicle, the vehicle returned to normal driving operation. The contact hooked up his vehicle to a scanner and no fault codes were found. The contact then called the manufacturer where he was informed that this failure was a known issue and that he would have to take the vehicle to the dealer three times after experiencing each failure. The contact was not informed as to what would happen after the third visit to the dealer. The contact had taken the vehicle to a dealer where it had yet to be diagnosed and remained in their possession. The vehicle had yet to be repaired. The failure mileage was approximately 36,000.

I was driving in the rain on a dark desolate road. The engine began to malfunction, suddenly losing most power. The car would only go up to 20mph. I believe this condition is known as “limp mode”. Simultaneously the “check engine” light was illuminated. When I pulled off the road I shut the car off. I waited a couple of minutes and restarted the car. The condition miraculously disappeared. This was a very frightening experience because it happened on a major highway in the middle of the night.

Today, when accelerating on an onramp, merging into interstate traffic, the vehicle suddenly decelerated to about 30mph. Traffic, including a semi, was approaching at a higher rate of speed. I was able to get off the into the emergency lane but was concerned about being struck from behind. I stopped the engine, restarted it, and had no further problems. I tried to reproduce the problem but was unable. I contacted the dealer but was told it would be hard to repair if it wasn't reproducible and was advised to see if it recurred.

My wife purchased this car about one month prior to this incident. It was presented as a Certified Pre-Owned vehicle. While traveling on the PA turnpike, the car suddenly and with no warning went into "limp mode", with only enough power available to maintain about 20 mph. The "check engine" light came on, and we continued at about 20 mph on the shoulder, hoping to come to an exit. After a few minutes and no exit in sight, we stopped and turned off the engine while considering what to do next. When the air inside of the car became uncomfortably warm, I turned on the engine so we would have a/c. Immediately, it became apparent that the engine was working normally: no "check engine" light, plus other positive indications. We resumed our trip, arriving home safely. Our safety was at risk since the engine lost power with no warning whatsoever, and occurred while we were in a travel lane. As of this report, the car has not been taken to a dealer.
