4 Engine And Engine Cooling problem of the 2013 Acura ILX

Failure Date: 05/12/2024

Issue had not been persistent, on Sunday, may the 12th, 2024, while driving home, I was on a slight downward slope coming to a halt at a red light, when the car jolted slightly and the warning lights came. The auto-shutoff feature on the vehicle stopped working immediately. I was able to drive the car home, but after parking - the vehicle wouldn’t start again. Electronic screen on the radio came on and I could see error codes p1437 & p15a5. Also warnings on the dash to check ima system, check charging system, check battery, check breaking system. Power steering locked up due to the voltage shortage. What is the reason/explanation provided by the dealer, as to what caused this issue? dtc's p0a78 - mpi internal circuit malfunction, p1440 - mpi out circuit malfunction. Mpi failing internally, causing 12v battery to lose charge. Previously parts involved were recalled in Dec 2020, since american Honda didn’t not include my VIN they have refused to be of any assistance - monopolizing on being the only available source to change the parts. Had I received the recall, I would have had it addressed prior to the part going out. I’m 6330 miles over what they would have covered because I had no idea this was an issue until I found the safety bulletin which exactly described the recall and what happened to be my experience. Same issues, but I’m being told I couldn’t be included. They are charging me over $1400 for the part alone and then service which includes a complete removal of my back seats. I just spent nearly $4000 in Feb 2023 on the ac because the car wouldn’t start, who is to say this wasn’t undetected issue at the time?!.

7 Engine And Engine Cooling problem of the 2013 Acura ILX

Failure Date: 07/20/2023

On July 20th, 2023, while driving home from work, my vehicle without warning made a sudden jerk and all the warning light s came on the dash board. The car had reduced power and acceleration and an automated voice from the dash board warned to pull over the car. I pulled over into a garage who performed a diagnostic. They stated the error codes indicated mpi failure (ima power moter invertor). They also stated there was a service bulletin 20-021 for tis issue with this car (same year /model). When a VIN check was performed, the vehicle did not come up on this TSB. I had the car towed to an Acura dealer and they ran a diagnostic. They confirmed error codes p1440,p15a5,p0ae1,p0da8 - all codes listed in the service builletin 20-021 for this vehicle year, make and model. I have no doubt, as the data indicates, this failure/incident was caused by the same issues which are covered under TSB 20-021 and this VIN should be included.

8 Engine And Engine Cooling problem of the 2022 Acura ILX

Failure Date: 04/21/2023

I am experiencing what I believe to be unauthorized remote access/control of my 2022 Acura Ilx. I suspect the extra set of keys provided by the dealership was given to unauthorized parties without my consent. The vehicle has exhibited sudden and unexplained changes in acceleration, braking, steering, and electronic functions while I am driving, as though being controlled externally. This creates a severe safety risk to me, passengers, and others on the road. I have also experienced tampering with electronic systems, tracking, and possible interference with the onboard computer. This has been ongoing for an extended period and may involve multiple parties, including a former employer and individuals tied to them. The risk of losing control of the vehicle is constant, and I believe this is a safety defect that requires immediate investigation.
