2013 Acura ILXEngine & cooling

I am submitting this complaint to document what I believe is a recurring defect involving the air conditioning compressor on my 2013 Acura ILX Hybrid. Vehicle history: * 2013: Vehicle purchased new. * 2019: Original A/C compressor failed and required replacement. * 2026: Replacement A/C compressor has failed again. This means the vehicle is now on its third A/C compressor since new. Based on my experience, each compressor has lasted only about 4-6 years before failing. The first compressor replacement,...

performed by an Acura dealer in 2019, cost approximately $5,700. I have now been quoted approximately $3,600 by an independent repair facility and approximately $5,200 by an Acura dealer for the current repair. In addition to the extremely high repair cost, I have found that many independent A/C repair shops are reluctant to perform this repair because of the complexity and expense of replacing the compressor on this hybrid model. Replacement options are also very limited because this compressor is essentially an Acura OEM-specific component, with few, if any, widely available equivalent alternatives. The current failure began with a rattling/chattering noise whenever the A/C was engaged. Eventually, the compressor load became severe enough that the accessory belt was thrown off when the A/C engaged. An independent mechanic inspected the vehicle, ruled out the belt tensioner, and concluded that the compressor is the source of the problem. While compressors are wear items, replacing the compressor three times over the life of the vehicle - with each unit lasting only about five years - appears to be an unusually short service life, especially considering the exceptionally high cost of repair. In my opinion, this suggests a potential design or durability issue with the compressor used in the 2013 Acura ILX Hybrid. I am requesting that NHTSA document this complaint and review whether other owners of the same vehicle have experienced similar repeated compressor failur

2022 Acura ILXElectrical systemEngine & cooling

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.

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?!

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).

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.

recall). Powertrain and transmission leaking, check hill start assist system, check vsa system, found recall for powertrain on internet that was from july 2019 that I have not been notified about. Complained about paint fading on hood over engine, complained about shocks and struts that don't need replacement but there is something loose that is making noise, I have updated home address with acura but even so when I moved in 2017 I did a chang of address. They have replaced alternator, that I don't believe needed changing at that time, service tech at one dealership told me if I serviced my car would burn up but of course offered me to buy a new car. Acura service at several dealerships have never given me pictures or mentioned transmissions leak but honda gave me all evidence. Metal sound transmission is permeated showing this has been a problem threw several inspections that are all documented with acura.
