Do Acura RDX have transmission problems?

Generally, Acura RDX models built in recent years are considered reliable, with no widespread transmission defect reported across the lineup. Isolated complaints exist, but many are tied to software updates or specific model-year issues rather than a systemic failure.

Understanding the RDX transmission system

The Acura RDX uses a nine-speed automatic transmission in most modern iterations. This design aims to balance fuel economy with responsive performance. Like any modern automatic, its behavior can be influenced by software calibration, fluid condition, driving style, and environmental conditions. Dealers can apply software updates (TCM calibrations) and perform maintenance to address shifting smoothness and engagement concerns.

Before diving into common concerns, it’s important to note that most RDX owners enjoy smooth shifts and dependable operation. The following sections summarize reported symptoms and recommended actions, drawn from owner feedback and official maintenance guidance.

Common transmission concerns reported for the RDX

The following items have appeared in owner surveys, reviews, and regulator complaint databases. They are not universal and often involve model-year-specific quirks or maintenance-related factors.

• Rough or hesitant shifting, especially during cold starts or low-speed driving.


• Shudder or judder during acceleration or after a stop, sometimes described as a brief “shimmy” as gears engage.


• Delayed downshifts or a perceptible lag when accelerating to merge or pass.


• Slippage or inconsistent clutch/torque converter feel in certain situations.


• Warning lights or transmission malfunction messages prompting dealer inspection, with some cases resolved via software updates or component reprogramming.

Concluding: While these symptoms have been reported, they are not universal, and many owners experience normal, trouble-free operation. When they do occur, they are frequently addressable through updates or maintenance tasks.

What to do if you suspect a transmission issue

If you notice persistent or worsening symptoms, follow these practical steps. The goal is to confirm whether a software, maintenance, or hardware issue is present and to determine the appropriate remedy under warranty or service plans.

• Check for open recalls and Technical Service Bulletins (TSBs) related to the RDX transmission with your dealer or on official manufacturer sites.


• Ask your dealer to check for software updates to the transmission control module (TCM). A software calibration can improve shift quality and response without major hardware work.


• Inspect transmission fluid condition and level if your model requires periodic fluid servicing. Replace or top up as recommended by the owner’s manual and dealer guidance.


• Document symptoms with dates, speeds, and actions leading up to them. This helps technicians reproduce and diagnose the issue.


• If under warranty, have the dealership perform required service. For out-of-warranty vehicles, compare the cost of software updates versus potential component repairs or replacements.


• Consider an independent second opinion if a dealer assessment seems inconclusive, especially for older model-years or higher-mileage vehicles.

Concluding: Most transmission-related concerns can be addressed without a major repair, particularly when action is taken early and within warranty coverage or through service bulletins.

Reliability, recalls, and long-term ownership

In overall reliability surveys and owner feedback, the RDX tends to score well for its class. There have been recalls and service campaigns over the years that touch on transmission electronics or related systems, so checking current recall status is prudent for prospective buyers and current owners alike. In practice, routine maintenance, timely software updates, and prompt attention to warning indicators greatly reduce the likelihood of serious transmission trouble.

Warranty coverage and recalls

Warranty terms for the RDX typically cover major powertrain components for a defined period or mileage, with variations by model year and region. Always verify the exact coverage on your vehicle and review any active recalls through official channels such as NHTSA’s recall database or Acura’s consumer portal. Addressing recalls and service campaigns early helps prevent long-term reliability issues.

Maintenance and preventive care

Adhering to the recommended maintenance schedule—especially regarding fluid condition and software updates—helps keep the nine-speed automatic operating smoothly. If you drive in harsh conditions (extreme heat, heavy city traffic, or frequent towing), more frequent checks or early intervention may be warranted.

Summary: The Acura RDX does not suffer from a universal transmission defect, but like any modern automatic, it can exhibit symptoms that range from mild nuisance to significant concern in isolated cases. Most issues are manageable through software updates, routine maintenance, and timely dealer intervention. For prospective buyers, reviewing the vehicle’s recall and service history and ensuring current maintenance can reduce the risk of transmission-related surprises.

In closing, the RDX remains a strong option in the luxury compact-SUV segment, with the majority of owners reporting reliable performance. As with any used car purchase, a thorough pre-purchase inspection and a current service record are essential to gauge the likelihood of transmission-related problems down the road.

Do Acura RDX have transmission issues?

Transmission problems were the second most reported problem on the 2021 Acura RDX and comprised seven of the fifty-eight total complaints. Transmission problems involve the vehicle's transmission and gear system, which moves power from the engine to the tires and allows the vehicle to accelerate or decelerate.

What year of Acura RDX to stay away from?

The Acura RDX years to avoid are generally the 2015, 2019, and 2021 models due to significant issues. The 2019 is often cited as the worst, especially the first model year of the third generation, with problems like engine stalling and power loss. Other years with notable problems include the 2013, 2014, and 2018.
