DIY maintenance guides at au7o.io.
On the 2014-2020 Acura RLX, the RLX develops premature wear of the front lower control arm bushings and rear trailing arm bushings, leading to vague steering, clunking over bumps, and uneven tire wear. The soft rubber compound used in the bushings degrades faster than expected, particularly in regions with temperature extremes.
Replace the front lower control arm bushings or the entire control arm assembly. Replace the rear trailing arm bushings. Perform a four-wheel alignment after bushing replacement. Consider upgraded polyurethane bushings for longer service life, though they transmit more road noise.

On the 2014-2020 Acura RLX 3.5L V6 Hybrid, the RLX Sport Hybrid with the SH-AWD system develops a noticeable whine from the twin rear electric motors during low-speed EV driving and regenerative braking. The motor bearings produce an increasingly loud whine as mileage accumulates, and the vibration transfers through the rear subframe into the cabin.
Have the rear motor unit inspected at an Acura dealer equipped with hybrid diagnostics. The rear motor assembly may need replacement if bearing wear is confirmed. Update the hybrid control module software which can adjust motor operation to reduce noise in mild cases. Replacement requires draining and refilling the rear motor coolant circuit.
