The keyless access unit broke around 100k miles. Car acted like it was having a seizure. If car was locked, alarm goes off nonstop (during these episodes, which are intermittent) and all dash lights and head lights blink on and off over and over in quick succession. If car was not locked, only the lights had a seizure, there would be no audible alarm. Seemed to happen more near towers (cell towers, fire station broadcast tower, absolutely could not leave the car alone in nyc and had to go home). So so so embarrassing. So many people with this issue.

Multiple warning lights by model year
What owners say
My daughter was driving her car to work. Well in the middle of rush hour traffic the car put itself in neutral and then would not move and all of the lights were displayed on the dashboard as if the car was turned off. The car would not go into gear to move forward. She put the car in park and then shut the engine off. The engine shuttered and the car shook while it turned off. He then tried to start it and then started again and it started up okay and was able to put the car in drive and move forward. I spoke to my mechanic and he said that there is a recall on this car for fuel pump issues. I checked the VIN and it said that there was no open recall. However I wanted to report this incident to document it for this particular car because it could have a fuel pump issue.
On May 11, 2024, while driving my 2017 Acura TLX on a local city street, multiple dashboard lights suddenly came on. Since that time these lights began to come back on more frequent and often will go into a Limp Mode. I have had the vehicle inspected at my local Acura dealership only to be told that the vehicles rear PAWS Actuators and Control Unit need to be replaced at a cost of around $8,000. They also informed me that a recall for this issue was only for the 2015 TLX and RLX models but there could be a recall for my model year at some future date. I find this to be unacceptable as I have found out there are multiple instances of this same issue happening with many other Acura owners.
Car experiences intermittent electrical system failure. Upon failure, drivers will experiance random and rapid clicking, clanking, and electrical systems discharging like lights, screens, and alarm. After restarting the car, users will find, all warning lights displayed with a few blinking: transmission, parking brake, traction control, a few more. Headlights will randomly turn on, as well as the alarm, intermittently. All ADAS offline. Experienced sudden system failure causing all ADAS to fail while stationary/parked or moving/(actively driving on highway). Does actively affect driving ability more specifically: disrupts steering ability, causes random malfunctions with electrical components, cannot exceed 40 mph, car will not shift above 3rd gear, engine does seem much louder. After a thorough investigation/diagnosis with the dealership I concluded the main fault is due to the "Smart Power Control Unit" located behind the glovebox compartment of the vehicle. More specifically, one of the chips on the circuit board is not fully coated with sealant from the factory, leading to a potential for some kind of mold, dust, or organic growth to form and short one of the ground pins on the end of the chip. Driver States: This is a control unit failure, I believe a small short on a single ground pin with the positively charged chip housing was causing a short within the control unit circuit board where the chip was not fully covered with non-conductive coating/sealant. This caused a handful of issues, like electrical systems prematurely wearing due to rapid discharge of electronics. Impairs drivers ability and ability in turning, braking, and accelerating. Also car will roll backwards if driver is not careful. BIGGEST CONCERNS: FIRE, partial loss of control while driving, and premature wear on electrical components. A extra note: Disconnecting battery does temporarily fix issue but rarely, most time it will start discharging electrical systems immediately or in the day.
In 2017 I had the car lose throttle power when pressing the gas pedal and every light in the car began to flash. I let off the pedal several times and tried accelerating again and this did not work. I pulled over to the side, put the car in park and turned it off. After about 15 minutes or so of trying the car finally started. But the check engine light was still on and so was the warning of "emissions system problem" and "emergency parking break problem". The next day I dropped the car off at acura. They called the next day and told me the car had malfunctioned and tripped the sensors but they cleared the codes and everything was fine. They also tried to blame my lengthy roadtrip for the malfunction. When you spend 40,000 dollars on a car that has 6,000 miles on it you do not expect a "malfunction" but I accepted the result and walked away. In 2018 it happened again. The lights began to flash and I lost all throttle respone. But suddenly the car downshifted into 4th gear(going 60mph) and was sitting at about 4500 rpms and I was unable to shift but regained throttle response so I pulled over. I allowed the car to sit for about 15 minutes and the car started with no problems. I did not take the car to the dealer this time because all of the lights had cleared overnight. In june 2019 this had happened again for the last time and I took the car straight back to acura and told them to figure it out. They called me 2 days later and told me they had to update my transmission control module. That was covered under warranty and said they fixed it. So I assumed the problem was fixed and I was extremely happy. But now just the other day august 19th 2019 the throttle lost complete power again except this time no lights came on. I pulled over to the side turned the car off and back on with no issues. Could you please help with this matter. Thank you very much for you time!
