The 2007 Acura RL has 6 recalls, the most serious being defective Takata airbag inflators on both the driver and passenger sides that can rupture and send metal fragments into the cabin, causing serious injury or death.
Both frontal airbags are affected. Prior repair attempts did not fully resolve the issue across all affected vehicles, which is why multiple filings exist for the same underlying defect. Whether the airbag deploys in a crash or not, a ruptured inflator can scatter sharp metal shards toward anyone seated in the front of the car. This is among the most widespread and serious defects in automotive history, and the 2007 RL appears in multiple rounds of the campaign covering both the driver and passenger inflators.
On the braking side, the brake master cylinder in certain vehicles was filled with a fluid that contains polymers. Over time, those polymers can break down and cause the master cylinder to leak internally. As fluid escapes, the brake pedal may feel softer or behave differently underfoot, and braking performance can gradually worsen, raising the risk of a crash if the driver cannot stop the car as expected.
