Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners report catastrophic transfer case and transmission failures concentrated around 50,000–83,000 miles, with one case at 1,071 miles. The most common failure involves shearing of the splines connecting the transmission to the transfer case, which silently disables the all-wheel-drive system. Critically, the dashboard continues to display the vehicle as AWD-capable while it operates in front-wheel-drive only—with no warning lights, fault codes, or alerts. Owners discover the problem only when traction is needed: stuck in snow, unable to climb inclines, or experiencing severe tire spin on acceleration. The result is dangerous understeer, loss of directional control, and vehicles becoming stranded. One owner had already replaced the transfer case seven months prior at 57,000 miles before experiencing another complete failure at 64,000 miles. Early transmission issues include fluid leaks and noise at low mileage (450 miles), transmission faults limiting acceleration to 25 mph, and jerking during low-speed operation. A single report describes total electrical failure for 5.5 hours while parked in a garage—trapping occupants with no door or window operation. NHTSA opened investigation DP26001 in March 2026 following a petition citing 48 complaints alleging the same spline failure. Warranty repairs have been performed by dealers, though replacement costs cited reach $16,000.

Failure modes owners describe
Transfer Case and Transmission Spline Shearing
The interfacing splines between the transmission and the transfer case/power take-off unit fail, preventing power transfer to the rear wheels. Owners report the transfer case becomes stripped or shredded, causing sudden loss of AWD functionality and forcing the vehicle into front-wheel-drive only mode.
When: Reported between 50,000 and 83,000 miles; one failure at 1,071 miles; one at 64,000 miles with prior transfer case replacement at 57,000 miles
Symptoms owners cite: Sudden loss of AWD with no warning lights or indicator messages; Vehicle operating in FWD only while system displays AWD active; Loud clunking, banging, or popping sounds during acceleration or from a stop; Severe front wheel spin and tire slip under acceleration; Loss of traction and directional control, especially in snow or wet conditions; Difficulty climbing inclines despite AWD badge; Understeering in corners; Front differential leak at gasket
Codes mentioned: NHTSA Action DP26001
Repairs/costs cited: Complete transmission and transfer case replacement. Owners cite costs up to $16,000; covered under warranty in most cases reported.
Recalls/TSBs owners mention: NHTSA opened investigation DP26001 on March 6, 2026, following a petition alleging spline failure in MY 2021–2023 TLX and MY 2022–2023 MDX. Acura/Honda has replaced failed components under warranty. One owner references Honda USA coordination with dealership regarding warranty coverage.
Transmission System Fault with Limp Mode
Transmission system faults cause the vehicle to enter a reduced-power or limp mode, preventing normal acceleration. Dashboard warning messages indicate transmission system problems. Failures occurred very early in vehicle ownership.
When: One reported at 1,071 miles (4 days after purchase); occurs intermittently in other cases
Symptoms owners cite: Engine revs but vehicle does not accelerate; Vehicle slows down despite pressing accelerator; Transmission system fault warning on dashboard; Emission system problem warning message; Vehicle limited to very low speed (25 mph in one case); Vehicle jerks during acceleration from stop; Grinding noise while accelerating from stop; Metal chunks found in transmission and transfer case
Codes mentioned: Transmission System Problem warning message, Emission System Problem warning message, Brake Fault warning (intermittent, unresolved)
Repairs/costs cited: One transmission failure diagnosed within hours of purchase; another owner at 80,000 miles found metal debris requiring full transmission and transfer case replacement.
Recalls/TSBs owners mention: Acura dealer requested transmission replacement on the 1,071-mile vehicle. One owner reports Acura service claimed a brake fault warning is normal and working as designed with no fix available.
SH-AWD System Failure Without Warning Indication
The Super Handling All-Wheel Drive (SH-AWD) system fails silently in low-traction conditions. The system does not distribute power to the rear wheels despite the dashboard display indicating AWD is active. No fault codes or warning messages alert the driver to the malfunction.
When: During winter freeze event; multiple cases in snow and wet conditions
Symptoms owners cite: Rear wheels receive no power despite AWD being displayed as active; Significant wheel slip under light throttle; Inability to climb slight inclines; Vehicle performs poorly in inclement weather; Stuck in snow with no power to rear wheels; No warning lights or diagnostic messages displayed
Codes mentioned: No fault codes detected by driver; dealer inspection confirmed SH-AWD system failure
Repairs/costs cited: Failed SH-AWD components replaced under warranty. Specific part names and costs not detailed in narratives.
Recalls/TSBs owners mention: Warranty replacement of affected SH-AWD components confirmed by authorized dealership.
Transmission Noise and Fluid Leaks (Early Mileage)
Vehicles exhibit transmission noise and fluid leaks very early in ownership. Dealership initially misdiagnosed issues as normal break-in noise despite fluid loss, requiring multiple service visits.
When: At 450 miles on vehicle purchased August 19, 2021
Symptoms owners cite: Noise while shifting from Park to Reverse to Drive; Transmission fluid and oil leaking; Whining or whistling noise at 40–65 mph speeds (unresolved across multiple visits)
Repairs/costs cited: Vehicle brought to service three times for noise and leak diagnosis. Service manager eventually traced the issue; specific repair not detailed.
Recalls/TSBs owners mention: Initial service dismissal claiming break-in period normal for new engine. Third service visit by service manager led to identification and repair attempt.
Sudden Complete Powertrain Loss
Vehicle loses all electrical power and becomes completely unresponsive. Doors lock and windows do not operate, creating a potential entrapment hazard. Vehicle does not respond to normal start procedures.
When: While backing into garage after church service
Symptoms owners cite: Vehicle becomes completely unresponsive (dead); Loss of all power including door locks and windows; Vehicle unresponsive for 5.5 hours; No warning signs before failure
Repairs/costs cited: Not specified; vehicle was at Vandergriff Acura in Arlington, Texas (last serviced 6/13/2025).
Transmission Jerking at Low Speeds and During Deceleration
Vehicle jerks or lurches unexpectedly when decelerating from highway speeds or coming to a stop, especially at very low speeds or during final braking. Problem persists despite software updates and transmission resets.
When: During deceleration and low-speed driving; problem unresolved after multiple visits
Symptoms owners cite: Jerking during deceleration from high speed; Lurching or forward jerk just before complete stop; Vehicle may lurch forward several inches unless brakes applied firmly; Especially noticeable at very low speeds; Problem persists despite transmission resets and software updates
Repairs/costs cited: Transmission resets and software updates attempted without resolution.
Recalls/TSBs owners mention: Dealership has not provided adequate follow-up or resolution despite multiple visits.

What owners are reporting 2 most recent
When the vehicle decelerates—either from high speed or while already moving slowly—it frequently jerks just before coming to a complete stop. This issue is especially noticeable at very low speeds or during final braking, where the vehicle may lurch forward by a few inches unless the brakes are applied firmly. Despite multiple visits to the dealership, including transmission resets and software…
The vehicle makes noise while shifting from Park to Reverse to Drive. Transmission fluid and oil fluid leaking while I had driven only 450 miles. Had reported the issue to the Service Department. They informed that since the engine is new it will take a while for the transmission gear to quiet it down. They can't find any leakage for the first two times when I brought the vehicle for them to…
