The contact owns a 2015 Acura TLX. The contact stated that while her grandson was driving approximately 40 MPH, the vehicle stalled. There was no warning light illuminated. The contact called for tow truck service, but the tow truck driver was unable to shift the transmission into neutral(N).

The contact had the vehicle towed to a dealer and was informed that there would be a cost for the vehicle to be diagnosed. The contact requested a diagnostic test and was informed by the dealer that there was a hole in the oil pan, causing engine oil to leak out and causing the vehicle to stall. The contact had called the Insurance Company about the hole in the oil pan and was advised to have the oil pan and engine inspected. The dealer found that the hole in the oil pan had been caused by a fractured crankshaft that punctured the oil pan. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 73,000.

My 17 year old son drove across town about 6-7 miles from home, on a back road. Out of nowhere, his 2015 TLX started to make a sound like knocking or thumping. Just moments afterwards, most if not all of the engine warning lamps illuminated at once.. He pulled off as best he could there was a loss of power and massive amounts of steam pouring out from the under hood. At sunrise I went to the car to wait for AAA I was astonished at the mess on the pavement under and around the car, and even more surprised to hear from my mechanic told that the engine had seized. I remember my mechanic using the word "warped" to describe it to me. I had him replace the engine, as I was I unaware of the recall at that time. It was not inspected by anyone besides my mechanic.

Connecting rod bearing seizure leading to engine failure on the TLX 2018 engine 3.5 liter V6 engine. Our 2015 TLX Acura we had to replace our engine because of the connecting rod bearing seizure and our extended warranty covered it around 2020. In 2023 the second the Acura motor which is TLX 2018 engine 3.5 liter V6 failed due to same problem, connecting rod bearing seizure. Acura will not do a recall on that motor. They say because its was manufacture in a different warehouse its not covered or a problem. I know there are other people struggling with the same issues on the 2018 engine. I know there are other investigations on this motor.

Three years ago, the car started stalling at traffic lights coming to a stop battery was replaced and the problem went away. A new battery was installed a few months ago and in the last week the same stalling situation has occurred three times. Acura says there’s a software update, and when the car was brought in for the recall on the connecting rod bearings, they said they refreshed the software pertaining to this issue, but obviously it does not work others say that it has to do with the idle stop and that disabling it resolves this problem. I haven’t tested this yet, but I am going to, but it’s an ongoing problem. That’s a major safety concern and could cause a fatal accident.

Unable to get an appointment to address the Connecting Rod Bearing recall until May 12, 2025 which is the earliest available. Apparently, Acura is not providing their dealers with enough required tools and parts to do more than 5-6 recall appointments per week with some weeks having no parts available. Given that the engine can actually seize if this issue is present, being asked to wait until May 2025 is simply I unacceptable and does not meet your comment on your website about effecting the repairs in a “timely manner”. I have contacted 4 different dealers and all report the same issues with lack of tools and parts. Acura needs to step up acquisition or manufacturing of tools and parts.

When the vehicle is running in driveway and I then get into it a few minutes later and drive around the corner, when coming to a stop it jerks as if it wants to stall. This happens when I am driving as well and slow down, it’ll jerk and push me forward a little and happens daily so not sure why my vin didn’t come up with a recall because it sounds a lot like the fuel pump issue the one recall mentioned.
