Iâve bought my 2018 Acura TLX used from Holiday Mazda in [XXX] in XXX Now that my nightmare with the Auto Engine Idle is over(the shop that replaced my starter in November 2025 some how got it so it doesnât work anymore. But thatâs not my issue. Iâve had this issues 5-8 times in the last 2 years. I will be driving and my top screen in in the dash(it usually displays navigation, CarPlay, etc) will turn off and flash a couple times. Then it take out my âradioâ screen. Itâs like itâs resetting because the screens remind me when it electronics reset snd start up. It goes for a total of 2-3 times. Thank the Good Lord my car keeps driving safely. Here is the second issue. Iâve…

Driving car and suddenly all the lights on the dash light up and car goes into âlimpâ mode. Upon pulling over turning car off and turning back on lights are all still lit up. Plug car into obd2 scanner and car is showing code p0087 low fuel rail pressure. This is extremely dangerous as the car will randomly do this and will go into limp mode which can easily cause me to get into an accident. No active recalls on this but Iâm seeing this is a common issue with these Acura tlx models. Why hasnât this issue been addressed yet Acura?! For reference I drive a 2018 Acura tlx base model 2.4 cylinder

I bought my 2018 Acura TLX a-spec V6 in Nov. 2021, certified pre-owned from an Acura dealer. It had warranty through 100k miles. At just under 70k miles, around mid-2023 I believe, the engine seized and would not start. Warranty covered engine replacement. This was just around the time of the 3.6L V6 engine recall. I waited on the recall because the engine was brand new at that point. A year or so later, deal did inspect the engine for recall, but determined it was not part of the recall. Come current to late April 2026, just before engine #2 hit 70k miles (total miles on car ~139,000), engine has seized again. Driving on freeway and car went into limp mode, thankfully close to home and…

I was rolling up to a stop light at approximately 20 mph when the frontal crash mitigation feature suddenly slammed the brakes on fully to a complete stop. I searched the web and found that there are other owners of this model that have had similar occurrences. I could easily have been rear-ended if someone had been following. I was lucky that didnât happen. Since that day, I have been afraid to drive the car until I have disabled the feature.So every time I start my car I have to disable this mode. There is no known fix. No technical service bulletins etc. regarding this problem. Honda Acura needs to find a solution to this. I should not have to disable a safety feature that is actually…

The vehicle experienced vibration symptoms and stalled on the road. The day before it stalled, there were rattling noises which prompted me to take the car to the dealership the next day. I had just received the letter about the recall so I knew it was likely related. The car was towed to the Acura dealership but the dealership denied recall coverage, stating the engine number did not match the recall list. During the discovery process, it was later discovered that the engine had been swapped by the dealership in 2018 â a fact that was not disclosed to me at the time of my purchase. The installed engine still falls within the recall defect interval of 2015-2020 but they are resistant to…
