What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2018 Acura Rlx Hybrid, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
My engine malfunctioned by throwing a rod, causing the car to lose power and leak oil on the lower passenger side of the engine bay onto the floor below. I was driving to work on a busy highway at the time, and I had to pull over immediately to avoid collisions from other vehicles on the highway. The car immediately became undrivable. I had check engine lights visible on the dash after the incident and I could smell the oil that had leaked from the engine from inside the car. I had to call AAA to have them tow my car to the dealership for service. My engine had to be replaced. The engine had to be ordered, and it took them a little over 2 months to complete the necessary work to fix my vehicle. The problem was confirmed and addressed by the dealership once the vehicle arrived at the service location. The manufacturer inspected the damaged parts and offered a viable solution to repair the vehicle. The warning lamps were visible immediately after the incident occured. No warning lights were present prior to the failure.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
No incidents so far. However, it is causing a lot of anxiety knowing that the car could potentially stall or crash since I received the email notice on 12/18/2023. What is a reasonable wait time?

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
