What is the warranty on a 2018 Acura RDX?


The 2018 Acura RDX is a luxury compact SUV known for its reliability, performance, and advanced features. If you own or are considering purchasing a 2018 Acura RDX, understanding its warranty coverage is essential for ensuring peace of mind and managing potential repair costs. Below, we’ll break down the warranty details for this vehicle and what you need to know about coverage and limitations.


Factory Warranty Coverage for the 2018 Acura RDX


When the 2018 Acura RDX was sold new, it came with Acura’s standard factory warranty, which includes the following coverage:



  • Basic Warranty: 4 years or 50,000 miles, whichever comes first. This warranty covers most components of the vehicle against defects in materials or workmanship.

  • Powertrain Warranty: 6 years or 70,000 miles, whichever comes first. This warranty covers the engine, transmission, and drivetrain components.

  • Corrosion Warranty: 5 years with unlimited mileage. This warranty protects against rust-through on the vehicle’s body panels.

  • Roadside Assistance: 4 years or 50,000 miles, whichever comes first. This includes services like towing, flat tire assistance, and battery jump-starts.


It’s important to note that these warranties are only valid for the original owner or subsequent owners if the vehicle is still within the warranty period. Additionally, the warranty does not cover regular maintenance, wear-and-tear items (like brake pads or tires), or damage caused by accidents or misuse.


What If the Warranty Has Expired?


Since it is now 2025, the factory warranty on a 2018 Acura RDX has likely expired for most vehicles, especially the Basic Warranty and Roadside Assistance. However, the Powertrain Warranty may still be valid if the vehicle has fewer than 70,000 miles and was purchased less than six years ago. If the warranty has expired, you have a few options:



  • Extended Warranty: Acura offers extended warranty plans that can be purchased before the original warranty expires. These plans provide additional coverage for major repairs.

  • Third-Party Warranty: You can also purchase extended warranties from third-party providers, though it’s essential to research their reputation and coverage details.

  • Regular Maintenance: Keeping up with regular maintenance can help prevent costly repairs and ensure your vehicle remains in good condition.


If you’re unsure about the warranty status of your 2018 Acura RDX, you can contact your local Acura dealership or check the vehicle’s warranty booklet for more details. Additionally, the dealership can provide information on extended warranty options if you’re interested in additional coverage.


Conclusion


The 2018 Acura RDX came with a robust factory warranty that provided excellent coverage for the first few years of ownership. While most of the original warranties have likely expired by now, the Powertrain Warranty may still be active for some vehicles. If you’re considering purchasing a used 2018 Acura RDX or want to ensure your current vehicle is protected, exploring extended warranty options or maintaining a regular service schedule can help you avoid unexpected repair costs.
