The 2021 Acura RDX marked a new generation for the luxury compact crossover SUV, combining sleek design, a comfortable ride, and advanced technology. With its performance-oriented turbocharged engine, high-quality interior, and impressive list of features, the RDX quickly became a popular choice for those looking for a more affordable luxury vehicle. However, as with any car, the RDX is not without its issues. This article will explore the common problems owners have reported with the 2021-present Acura RDX, provide guidance on what to look for when buying one, estimate ownership costs, and offer alternatives that could be worth considering if you're looking at other models in the same class.
Common Problems of the ACURA RDX (2021-Present)
1. Infotainment System Glitches
One of the most widely discussed issues with the 2021-present Acura RDX is its infotainment system. Acura’s True Touchpad Interface (TTI) replaces the traditional touchscreen with a touchpad controller, which some drivers have found to be difficult to use and prone to occasional glitches. The system can sometimes freeze, delay, or fail to respond properly, causing frustration for owners.
Common Issues:
- System freezes: Some users have reported the infotainment system freezing while using navigation or streaming audio.
- Touchpad responsiveness: The touchpad can be overly sensitive or unresponsive, making it harder for drivers to control the system smoothly.
- Audio system malfunctions: There have been complaints of intermittent audio loss, especially with the premium audio systems, making it a source of annoyance for owners who prioritize high-quality sound.
What to Look For:
- Test the system thoroughly: During a test drive, ensure that the infotainment system operates without lag or crashes. Test all key functions, including navigation, media controls, Bluetooth connectivity, and Apple CarPlay/Android Auto integration.
- Evaluate the touchpad: Try interacting with the touchpad to assess how responsive it is. If the touchpad feels too sensitive or unresponsive, it may indicate a fault.
2. Transmission Hesitation & Shifting Issues
While the 2021 RDX uses a 10-speed automatic transmission designed to provide smooth, responsive shifts, some owners have reported hesitation or sluggish shifting, particularly during low-speed acceleration or when moving from a stop. This can make the driving experience less refined and may be noticeable during daily commuting or in stop-and-go traffic.
- Common Symptoms:
- Hesitation during acceleration: A noticeable lag when pressing the accelerator pedal, especially at low speeds, can be attributed to transmission hesitation.
- Harsh shifts: Some drivers have mentioned experiencing jerky or delayed gear shifts, which detracts from the otherwise smooth ride that the RDX is known for.
- What to Look For:
- Test drive at various speeds: Pay close attention to how the RDX shifts under different conditions—such as during slow city driving, highway cruising, and rapid acceleration.
- Listen for unusual noises: Any grinding, clunking, or harsh shifting noises should raise red flags, and it’s important to have the transmission checked by a mechanic if these sounds persist.
3. Engine Problems (Turbocharged Variants)
The 2021 RDX comes with a turbocharged 2.0-liter 4-cylinder engine that delivers strong performance, but some owners have reported engine-related issues, primarily related to performance degradation and turbocharger malfunctions over time. While these problems are not widespread, they are still worth noting.
Common Engine Issues:
- Turbocharger lag: Some drivers report a delay in the engine’s response when accelerating, particularly when the turbocharger kicks in.
- Oil consumption: A few owners have noted excessive oil consumption, requiring more frequent oil changes or top-ups between standard intervals.
- Check engine light: The engine control unit (ECU) may occasionally trigger the check engine light due to issues with sensors or misfires, though these problems are often linked to software updates or small sensor malfunctions.
What to Look For:
- Accelerate on the test drive: Pay attention to any noticeable turbo lag or hesitation when the engine is pushed. Smooth, linear acceleration is a sign that the engine is functioning properly.
- Monitor oil levels: If you purchase a used RDX, ask the owner if they’ve noticed any unusual oil consumption or if the check engine light has been activated recently. Regular oil consumption can be a sign of underlying engine problems.
4. Brake Performance Issues
Another concern some owners have raised is with the brake system on the RDX, particularly the feel and effectiveness of the brakes. Although the RDX generally provides solid stopping power, a few owners have reported inconsistent brake performance, with some describing the brake pedal as feeling "spongy" or requiring more pressure than usual.
Common Symptoms:
- Spongy brake pedal: The brake pedal may feel softer than expected, requiring additional force to slow down the vehicle. This could indicate an issue with the brake master cylinder, air in the brake lines, or worn brake pads.
- Uneven braking: In rare cases, the car might pull to one side when braking, which could signal uneven brake pad wear or issues with the brake calipers.
What to Look For:
- Test the brakes during the test drive: Make sure the brake pedal feels firm and responsive. The car should stop smoothly and in a straight line without pulling to one side.
- Check for warning lights: If the brake system warning light appears on the dashboard during the test drive, this should be investigated further.
5. Suspension Noises & Ride Quality
While the RDX is designed to deliver a smooth, comfortable ride, some owners have reported hearing occasional suspension noises, particularly over rough or uneven surfaces. These noises can include clunks, creaks, or rattles coming from the suspension or chassis, which can negatively affect the overall driving experience.
Common Symptoms:
- Suspension clunks or rattles: These sounds can be caused by worn-out suspension components, such as strut mounts, control arms, or bushings.
- Unusual ride quality: A decrease in ride comfort, especially when driving over bumps or potholes, may indicate suspension issues.
What to Look For:
- Listen for unusual sounds: During the test drive, drive over bumps and rough roads to check for any strange clunking, rattling, or creaking noises from the suspension.
- Check ride comfort: Pay attention to how the car feels when driving over uneven surfaces. The RDX should provide a comfortable, composed ride, even on less-than-ideal roads.
6. Adaptive Cruise Control & Driver Assistance Issues
The 2021 Acura RDX comes equipped with a suite of advanced driver assistance features, including adaptive cruise control, lane-keeping assist, and collision mitigation braking. While these features are generally appreciated for enhancing safety and convenience, some owners have reported issues with the reliability and performance of these systems.
Common Issues:
- Adaptive cruise control malfunction: Some drivers have noticed that the adaptive cruise control can disengage unexpectedly or fail to properly adjust the speed based on traffic conditions.
- Lane-keeping assist failure: In some cases, the lane-keeping assist feature has been known to steer the vehicle too aggressively or fail to react to lane markings correctly.
What to Look For:
- Test the driver assistance systems: During the test drive, engage adaptive cruise control and lane-keeping assist to see how well they function. Ensure that the adaptive cruise control maintains the set distance and the lane-keeping assist reacts smoothly.
- Watch for error messages: If any warnings or error messages appear for the driver assistance systems, this could indicate an issue with the sensors or software.
What to Look for When Buying an ACURA RDX (2021-Present)
When considering a used 2021 or newer Acura RDX, it’s essential to be aware of the potential issues highlighted above, as well as some key factors that will influence the long-term reliability and cost of ownership.
- Service History: Make sure the car has been regularly serviced, especially the software updates for the infotainment system and transmission, both of which can sometimes require attention. Verify that any recalls or manufacturer service bulletins have been addressed.
- Warranty Coverage: The RDX comes with a 4-year/50,000-mile basic warranty and a 6-year/70,000-mile powertrain warranty. If buying a used model, check to see how much warranty coverage remains, as it can save you on repair costs.
- Inspection for Software Issues: Infotainment and driver-assistance system glitches can often be solved by software updates. Ensure that all systems are functioning as they should and inquire about any past software-related repairs or updates.
