2019 Acura RDX Reliability Report

Owners report frequent issues with the 2019 Acura RDX's power train, particularly involving sudden loss of power and the vehicle entering limp mode, often accompanied by a flashing check engine light. These incidents are commonly noted during acceleration, especially in wet conditions, and typically resolve temporarily after restarting the vehicle. Complaints often occur around 18,000 to 60,000 miles, with several owners mentioning a service bulletin related to the intercooler as a potential fix. Safety implications are significant, as the sudden deceleration and loss of power occur on highways and busy roads, posing risks of collisions. Additionally, a few reports mention fluid leaks and transmission issues, including metal shavings found in the transmission oil, which contribute to high repair costs.

Owners of the 2019 Acura RDX frequently report issues with the vehicle's electrical system, particularly involving sudden loss of power and stalling. Complaints describe scenarios where the vehicle unexpectedly enters "limp mode," fails to accelerate, or completely stalls, often accompanied by multiple warning lights on the dashboard, sometimes referred to as a "Christmas tree" effect. These issues typically occur during acceleration or while driving at highway speeds, posing significant safety risks due to loss of control. Another common issue involves the infotainment system, where the display screen may go blank, affecting visibility of critical safety features like the backup camera. These problems are reported across a range of mileages, with some owners experiencing failures shortly after purchase, while others report issues at higher mileages, such as 63,220 miles. Buyers considering a used 2019 Acura RDX should be aware of these potential electrical system failures and their associated safety implications.

Owners of the 2019 Acura RDX frequently report incidents of the rear windshield shattering spontaneously, often while the vehicle is parked and without any apparent external impact. Complaints commonly describe the glass breaking suddenly, sometimes with a loud noise, and shattering into small fragments, posing a risk of injury from flying glass. These incidents are noted to occur in various weather conditions, with some owners mentioning cold temperatures or the use of the rear defroster. The reports do not specify a consistent mileage range for these occurrences. The spontaneous shattering of the rear windshield can create visibility issues and potential safety hazards, especially if it happens while driving. Additionally, one complaint mentions a similar issue with the panoramic moonroof shattering. Potential buyers should be aware of these reported issues, as they could impact safety and repair costs.

Owners of the 2019 Acura RDX frequently report that the rear windshield or tailgate glass shatters unexpectedly, often without any apparent impact. This issue typically occurs when the vehicle is parked, and the door is opened or closed, but it can also happen while driving. Complaints often reference Technical Service Bulletin 22-014, although many vehicles with this issue are not covered by it. The failure is reported across a wide mileage range, from approximately 24,000 to 126,000 miles. No crashes or injuries are reported in connection with the shattering glass, but the issue may pose a safety risk due to the sudden nature of the failure and potential for glass debris.

Owners of the 2019 Acura RDX frequently report issues related to unexpected deceleration and loss of power, often described as the vehicle entering "limp mode" during acceleration. Common symptoms include the check engine light flashing, the vehicle failing to accelerate despite pressing the gas pedal, and the car stalling or decelerating unexpectedly, particularly when attempting to merge or pass on highways. These issues are sometimes noted in wet conditions, but not exclusively, with some reports occurring as early as 500 miles. Additionally, some owners experience unintended acceleration where the vehicle moves forward unexpectedly, even when the brake hold feature is engaged. Safety implications are significant, with several owners mentioning near-miss accidents due to sudden loss of power and unexpected vehicle behavior.

Owners of the 2019 Acura RDX frequently report issues related to the fuel pump, with symptoms including vehicle stalling and sudden loss of power while driving at highway speeds. Several complaints highlight that the engine shuts down unexpectedly, posing significant safety risks, particularly when vehicles stall in traffic or on highways. Some owners mention receiving recall notifications related to the fuel pump, but they express frustration over the unavailability of replacement parts, which has persisted for over a year in some cases. These issues often arise regardless of mileage, as reports include both new and previously serviced vehicles. Buyers should be aware of potential safety hazards due to fuel pump failures, which can lead to dangerous driving situations.

Owners report two primary issues with the 2019 Acura RDX's service brakes. First, multiple complaints highlight a persistent squeaking noise from the brakes, often described as loud and occurring consistently when stopping or applying pressure. This issue has been noted since purchase and persists despite multiple dealer visits, with no permanent fix provided by Acura. Second, some owners describe problems with the brake hold feature, where the brakes release unexpectedly when the engine auto start-stop system reactivates, potentially causing the vehicle to move forward unintentionally. These issues are reported across various mileage ranges, with some owners expressing safety concerns, particularly regarding the unexpected vehicle movement.
