All 2 Known Issues

On the 1998-1999 Acura CL, nHTSA Campaign ID 03V423000 (October 2003) covers 1998-1999 Acura CL models. The defect: the ignition cylinder body wears, which causes the shift interlock to malfunction. If the vehicle does not securely lock in Park because the worn cylinder allows the interlock to disengage, the vehicle can roll away even with the transmission in any non-Park position. This is distinct from NHTSA Campaign 02V120000 (2002), which covered 1997-1998 CL for a different ignition switch defect. The 1998-1999 model years are the overlap between the two recalls — those owners should check both campaign IDs against their VIN. The fix is a free dealer replacement of the ignition switch/cylinder assembly. As of 2026, safety recalls have no expiration date under 49 CFR §573.6, so eligible VINs can still be repaired free of charge.

Common Symptoms

Key can be removed from ignition with transmission in Drive, Reverse, or Neutral
Shift lever stays freely movable after key is removed
Steering wheel does NOT lock when key is removed (sometimes paired symptom)
Vehicle rolls when you exit on a slight grade with the key removed
Ignition switch feels notchy or unusually free

How to Fix

Check VIN at owners.acura.com/recalls or NHTSA recall lookup to confirm whether your specific car was included. If yes, schedule the free dealer fix — they replace the interlock assembly in about 30 min. If your dealer claims the recall is 'closed' or 'no longer covered,' escalate to American Honda Customer Service (800-382-2238) — safety recalls have no expiration date under federal law (49 CFR §573.6). If you can't get to a dealer, ALWAYS verify the shifter is fully in Park and the parking brake is set before removing the key. This is not a workaround — it's a discipline check that protects you while you arrange the free repair.

TipFree dealer fix under the original safety recall. Check VIN at owners.acura.com/recalls. If the dealer claims the recall is 'closed,' call American Honda at 800-382-2238 — safety recalls don't expire under 49 CFR §573.6.
NoteIf the symptom is present, NEVER leave the car running unattended or park on an incline without setting the parking brake AND verifying Park engagement with the shifter, until the fix is done.

On the 1997-1999 Acura CL 3.0L V6 J30A1, the 1997-1999 3.0CL uses an automatic transmission specific to its V6 model family (the 2.2CL/2.3CL 4-cylinder variants do NOT share this transmission and are not affected). Owners and independent transmission shops widely report failures: slipping under load, not shifting out of 1st until warm, harsh shifts, and eventually total failure. Reports of repeat failures are common. NOTE: this transmission failure pattern is more severe and better documented on the 2nd-gen 3.2CL (2001-2003) than on the 1st-gen 3.0CL; the 1st-gen exhibits the same underlying weakness but at lower failure rates. A critical maintenance detail: this transmission has minimal internal filtration, and the filter is not serviceable without complete teardown. Owners who power-flush a slipping unit dislodge clutch debris and accelerate the failure rather than fix it.

This issue also affects: Acura TL, Mitsubishi Outlander, Saturn Vue

Common Symptoms

Transmission won't shift out of 1st until engine is warm
Slipping in higher gears under load
Rough or delayed engagement from Park to Drive
Harsh thunk shifts when slowing
Burnt smell from transmission dipstick
Repeat failures within 30,000-60,000 miles after replacement

How to Fix

If symptoms appear, immediately switch to ONLY Acura/Honda ATF (never Dextron substitute) and start a regular drain-and-refill schedule at every engine oil change interval (6 months). Do NOT power-flush — this transmission has effectively no serviceable filter and pressurized flushing forces debris through tight passages. If slipping has already started, a transmission specialist (not a quick-lube) needs to drop the pan to check for clutch material in the fluid. Once debris is visible, only a rebuild fixes it ($2,500-3,500). Replacements/rebuilds may need a fresh torque converter — the original is a known weak point. Add an aftermarket transmission cooler at rebuild time; the factory cooling is undersized.

NoteDo NOT power-flush this transmission. It has minimal internal filtration and pressurized flushes dislodge clutch debris into tight passages. Drain-and-refill ONLY.
TipUse ONLY Acura/Honda ATF, never a 'compatible' Dexron substitute. Wrong fluid accelerates failure on this transmission.
TipIf you rebuild, add an aftermarket transmission cooler. Factory cooling is undersized and was a contributor to original failures.
