ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
I am formally requesting a neutral third-party arbitration review under the Magnuson-Moss Warranty Act to compel American Honda Motor Co. to provide a permanent mechanical remedy—specifically, the sourcing and installation of a brand-new, redesigned engine assembly (Engine #Four)— This vehicle frame is now on its third engine block. Car was bought 11/30/2024. At Grubbs Acura, fuel pump safety recall that involves flashing/re-calibrating the Engine Control Unit (FI-ECU) software was done. Just a few weeks after new fuel pump, the vehicle displayed sudden stalling symptoms. The engine suffered a terminal, catastrophic internal collapse. The vehicle was towed to Grubbs Acura where Corporate Honda directed a forced out-of-pocket internal engine teardown. The physical teardown explicitly confirmed a catastrophic connecting rod bearing failure (spun bearing) identical to the structural manufacturing flaws currently under active federal investigation by the NHTSA under Preliminary Evaluation PE25008 / RQ24-025. Corporate Honda subsequently issued a verbal agreement to fully reimburse my out-of-pocket teardown fees. Because a manufacturer will never fund diagnostic labor if evidence of owner fault is present, this corporate reimbursement serves as formal validation that no owner maintenance neglect occurred, and that the engine died exclusively from an inherent component defect. Gunn Acura (San Antonio, TX) confirmed with my vin, that Engine #3 was a warranty/dealer-installed replacement unit at 22,000 miles. It failed after less than 40,000 miles of total operation. A professionally manufactured and dealer-installed engine is reasonably expected to last well beyond 40,000 miles. The manufacturer network cannot utilize arbitrary part-ownership rules or uncooperative, fragmented dealer communications. The original factory-installed engine and the dealer-installed replacement engine both suffered identical connecting rod bearing failures.

POWER TRAIN
Transfer case failure. I was driving my 2021 Acura TLX Type S when I suddenly heard a loud pop from underneath the car. Right after that, the SH AWD system stopped working and the car was only driving in front wheel drive. There were no warning lights or signs before it happened, due to it being a mechanical failure and not an electrical one because the car does not have sensors for the transfer case. After getting it checked out, I was told the splines between the transfer case and transmission were stripped. I’ve also seen that a lot of other 2021 to 2023 TLX Type S owners have had the same problem. It’s concerning because the AWD system failed out of nowhere, especially since the car depends on it for traction and stability. The car now needs a new transfer case and possibly more drivetrain repairs. (Proof shown in pdf down below, only front wheels spinning)

ENGINE, POWER TRAIN
I drive a 2021 Acura TLX 2.0 L turbo 4 cylinder. I was driving to work on [XXX] on a busy street in Boyle Heights, Ca. When all of sudden I get a warning indicator “engine temp is high do not drive”. Pulled over immediately. Good thing I was in the far right lane and was able to pull over and not stall or get rear ended by another vehicle behind me. There were no warning, symptoms and indicators of the engine's overheating. My vehicle has been in great condition prior with no major or minor issues with my vehicle. We took it to two dealerships for diagnostics. The head gasket blown, empty coolant reservoir, cracked engine block, and other parts of the engine were affected. What if I was on a highway and the car stalled. I could’ve been seriously injured or seriously injured someone else on the road. Acura corporate is aware of our situation and refuse to own their engine safety defects. They want us to pay out of pocket to repair our vehicle. My car is 5 years old there is no way out of nowhere my vehicle should have this type of engine issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Accelerated and heard a loud noise and felt like I had driven through wood and one got stocked to the whelle. There was a lot of traffic so I was driving slow. The noice I heard was like something was stuck inside the wheel, like it was grinding. Dealer diagnosed a bad transfer case and transmission and they replaced both under warranty.

Was changing the oil on my car and noticed grease running out from between the transfer case and transmission and also fluid build up on the transfer case higher up a little below the driveshaft. The car has 41k miles on it, there should be no leaks. My concern is the transfer case/transmission spline failure issue.

} I am submitting an update to my previous complaint. In my original complaint, I stated that the vehicle had not received transmission service. After reviewing my records, I confirmed that a transmission fluid service (drain and refill with inspection) was performed at an Acura dealership in July 2024. Despite this maintenance, the transmission still failed at approximately 84,000 miles. I am providing this update to ensure the complaint is accurate

I am reporting a transmission failure in my 2021 Acura TLX with approximately 84,300miles. While driving under normal conditions, after about 30 minutes on the road, I came to a stop at a red light. When I attempted to accelerate again, the vehicle would not shift out of first gear. The engine would rev, but the transmission failed to upshift. I also experienced a hard and abrupt engagement when shifting the vehicle into reverse. This issue occurred suddenly without warning and made the vehicle unsafe to operate in traffic, as I was unable to accelerate properly or maintain normal driving speed. The vehicle has been regularly serviced at an Acura dealership. At the time of the incident, the transmission fluid had not yet been replaced but had recently been recommended during a scheduled service visit. The vehicle is currently at an Acura dealership where I normally get the car serviced. The dealership has diagnosed the issue as an internal transmission failure and is recommending a transmission replacement.

2021 Acura TLX A-Spec SH-AWD and my transmission is leaking from the seal between the transmission and the differential. Acura is not sure if they can cover it under warranty because I am slightly past the powertrain warranty even though they had my car about a week ago when it was just barely past that point and no one said anything about the leak on the transmission until I checked with a certified Acura mechanic somewhere else.This is not just some small problem because with fluid leaking and leaving it will eventually damage the transmission and the differential or even just make them completely give out. This can be gears grinding and overheating. It is not just a problem it is also a SAFETY HAZARD if this starts dripping onto the exhaust pipe or even on the road behind making traction a problem for someone behind. This needs to be under a recall not just warranty with how much I see this happening to these cars this is ridiculous we have to go through this.

FUEL/PROPULSION SYSTEM
I was refueling my vehicle at Fullerton Costco, the internal metal flap of the capless fuel filler neck is stuck closed and preventing me from inserting a gas nozzle to refuel the vehicle. I could not refuel my gas tank. Luckily, my vehicle still has some fuel left, enough for me to get to the nearest Acura dealer (Cerritos Acura) to have them fix it. It was expensive though for an issue that should not happen at all. Also, a vehicle cannot be refueled or has a failed fuel neck flap, it can become a safety hazard and this is the main reason I file this complaint against Acura.

FUEL/PROPULSION SYSTEM, STEERING
Subject: Vehicle Data Submission for Investigation DP26001 To the Office of Defects Investigation (ODI), I am submitting maintenance data for my Acura TLX Type S (VIN: [ВСТАВ ТУТ VIN]) to assist with the ongoing DP26001 investigation regarding the AWD Transfer Case (PTO) splines. The vehicle is a US-specification model currently operated in [XXX] . Maintenance Facts: At 29,000 km (18,000 miles): PTO fluid was changed. Metallic debris was observed in the fluid. At 43,000 km (26,700 miles): PTO fluid was changed again. Silver metallic shavings and "glitter" were clearly present. A magnetic drain plug was installed during this service to capture further debris. Symptoms: The vehicle experiences harsh downshifts and mechanical clunking at low speeds in traffic. I am providing this to ensure the failure rate is accurately tracked globally. Please add this VIN and data to the DP26001 file.
