DIY maintenance guides at au7o.io.
On the 2000-2003 Acura RL, the 2000-2003 Acura 3.5RL is one of the vehicles named in NHTSA recall 20V027000. The problem is not the air bag the RL left the factory with — it is a replacement driver frontal air bag module that some of these sedans received during a past vehicle repair. Honda reports a manufacturing issue with the NADI inflator in those replacement modules: the inflator may absorb moisture. If it has, the inflator can rupture during deployment and send metal fragments toward the driver or other occupants, or the cushion can underinflate and fail to properly protect the driver. Given the RL's age, many of these cars have had multiple owners and multiple repairs, so the repair history that determines whether your car is covered may not be known to you. The 875,966-vehicle figure attached to this recall is the total across the whole campaign, not an RL-specific count.
Common Symptoms
How to Fix
Acura dealers perform this work free of charge: they inspect the air bags and replace the driver frontal air bag inflator with an inflator of a different design where necessary. Notification to owners began October 1, 2020. Enter your VIN at nhtsa.gov/recalls to confirm whether 20V027000 is open on your RL — that is the only dependable way to check on a car this old — or call American Honda's Customer Support & Campaign Center at 1-888-234-2138.
On the 1996-2004 Acura RL 3.5L V6 C35A, like every C-series V6 Honda used in the 1990s and 2000s (Legend, NSX, CL, TL, RL all share the family), the RL's 3.5L C35A V6 has a distributor mounted at the back of the head and driven directly off the camshaft. Inside the distributor housing, an oil seal isolates the cam-driven shaft from the cap/rotor/electrical assembly above. By 100,000 miles the seal hardens, oil pressure forces engine oil past the shaft, and the cap fills with oil. Result: misfires (typically P0300 random plus individual cylinder codes P0301-P0306 since this is a V6), rough idle, hesitation. RepairPal explicitly lists distributor O-rings as one of the most common Acura RL oil leak points. The figure-8 oil cooler seal and oil filter housing gasket are the other two common leaks on this engine — diagnose carefully before assuming distributor. The C35A engine remained in the first-gen RL through the entire 1996-2004 production run, so this issue affects all years.

Engine misfires, especially under load or after warm-up
Check engine light with P0300 random misfire or P0301-P0306 single-cylinder
Rough idle that smooths out with throttle

How to Fix
There is no replaceable seal inside the distributor — the seal is between the rotating shaft and the bearing inside the cast housing. The only fix is replacing the whole distributor assembly. OEM Honda runs $400-700; Cardone remanufactured runs $150-250. While the distributor is out, also replace the distributor cap, rotor, and ignition wires — they're cheap and you're already at the parts. Inspect the cap and rotor on the old unit for oil contamination to confirm distributor was the source. If you also see leaks elsewhere (figure-8 cooler seal, oil filter housing), address those at the same time — they share access path. Total job: 2-3 hours independent shop.
Owner tips & cautions
TipReplace cap + rotor + ignition wires at the same time as the distributor. You're already there. Saves a future labor cycle.
WarningDon't assume distributor without inspection. RepairPal also lists the oil cooler 'figure-8' O-ring and oil filter housing gasket as common RL leaks. Pull the cap and check for oil before buying the distributor.
