My 2017 Acura was involved in a low-speed collision where it failed to stop in a timely manner, resulting in a total loss declaration. This vehicle had open safety recalls (including the fuel pump/rod bearing issues) that remained unrepaired for over 1.5 years. Despite multiple inquiries, the manufacturer failed to provide a repair timeline or remedy. I believe these unresolved defects directly contributed to the braking failure and subsequent safety incident.

The contact owns a 2017 Acura TLX. The contact stated that the vehicle was previously repaired under the federal safety agency Campaign Number: 23V751000 (Engine and Engine Cooling); however, the failure occurred five months after the recall repair. The contact stated that while driving at an undisclosed speed, the engine started knocking. The vehicle was taken to the dealer, who performed a valve adjustment, but the failure persisted. The manufacturer had an engineer inspect the vehicle at the dealer and discovered there was wrist pin play on piston #2. The contact was informed that the short block needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but refused to replace the short block due to aftermarket components on the vehicle. The failure mileage was approximately 94,000.

On September 30, 2024 I received a notice from Acura titled “Important Safety Notice” (Recall Number 23V‑751). The recall concerns a manufacturing defect of the engine crankshaft. On October 1, 2024 I contacted Nalley Acura of Marietta, Georgia about scheduling an appointment and was told that the first available appointment was not until July 24, 2025 (almost ten months later). I was also told that the recall is not a safety concern and that I can continue to drive my car. I find it incredulous that Acura can issue a “safety recall” and then claim that the first opportunity to perform the repair is ten months later. Being forced to wait ten months to repair a manufacturing defect is outrageous and dangerous. Is this a subterfuge by the Company to avoid performing the repairs? In addition, I am confused by the dealerships response that this is not a safety concern. The recall notice states “due to a manufacturing defect of the engine crankshaft, the connecting rod bearing can prematurely wear and seize, causing engine damage. A damaged engine may run improperly or stall while driving, increasing the risk of a fire, crash, or injury”. Is the recall notice incorrect - that the matter under recall is not a safety concern? Additionally, I received a call from Honda Customer Service on Friday, October 4, 2024. Among other things, I was told that as part of the recall, I may be charged for a "diagnostic test" if the dealership looks at my car and finds a repair is not needed. Waiting ten months for a safety recall is unacceptable and I hope the federal safety agency investigates this further and forces Acura to explain how it can take so long to perform the service caused by its manufacturing defect. Also, to incur a charge as part of the recall process is unacceptable and will only discourage consumers from taking their car to a dealer.
