⭐ NHTSA NCAP Crash Test Ratings
New Car Assessment ProgramNCAP crash tests measure how well a vehicle protects occupants in controlled frontal crash, side crash, and rollover scenarios. Stars are awarded per category (5 = safest). These laboratory results are independent of owner complaints and are performed by NHTSA engineers on new production vehicles.
NCAP crash test ratings for this model are not yet loaded or this vehicle was not tested in the years analyzed. NHTSA tests a subset of new vehicles each year. Check nhtsa.gov/ratings directly for the latest results.
AI Interpretation
Low ConfidenceAverageBased on a low-confidence dataset of 8 complaints across 2017–2026 model years, complaints are concentrated in the 2018 model year, with the engine being the most frequently reported component. No crash-related complaints were filed, and the vehicle has 5 recalls. The data suggests potential issues with the engine and electrical system, but the small sample size limits reliability.
- The engine accounts for 2 of the 8 total complaints, making it the most reported component.
- The 2018 model year has the highest number of complaints (4), while 2019, 2021, and 2022 have zero complaints.
- There are 5 recalls associated with this vehicle across the analyzed years.
- ENGINE
- ELECTRICAL SYSTEM
- VEHICLE SPEED CONTROL
The 2018 model year has the most complaints (4), with the engine being a commonly reported component. However, with only 8 total complaints, this pattern may not be statistically significant.
Model years 2019, 2021, and 2022 show zero complaints, which may indicate fewer reported issues, but the low sample size means this could be due to low reporting rather than actual reliability.
- Inspect the engine for any signs of issues or prior repairs.
- Verify all open recalls at nhtsa.gov/recalls.
- Request service records for reported components like the electrical system and steering.
- Have a mechanic inspect the vehicle before purchase.

On my 2020 Acura RLX hybrid: On the same day, once in a parking lot and once on a side drive, traveling at less than 15mph but more than 5mph, the car suddenly accelerated upon which I slowed the car dowm by braking lightly. I have no idea why this happened. The original equipment rubber floor mat was correctly fastened and was not near the accelerator. The car only has 14,000 miles, is lightly driven. The fuel pump was replaced a year ago on tab recall. No other issues have been noticed.
Catastrophic engine failure at speed, connecting rod failure, which is a known failure for this engine. Engine blew, lost all power, and hot oil hit the hot exhaust and the car caught on fire. A fire truck came to put out the engine fire.

📖 Understanding This Data
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The Acura RLX has 8 complaints on record across 10 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The Acura RLX has 5 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 0 of the Acura RLX's 8 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.
How Is the AI Rating Calculated?
The AI reliability rating (Average) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. The rating provides a plain-English summary for buyers who want a quick verdict without parsing raw numbers. It is one input in your buying decision — always verify with a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all Acura RLX vehicles on the road — not any specific car. Two Acura RLX vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The Acura RLX has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
