2004-2008 Acura Tsx Recall 13V093: Engine ECU Corrosion

RN

Published June 2, 2026

Recall 13V093 affects 76,253 2004-2008 Acura Tsx vehicles for ECU corrosion that can stall the engine. Repair is free at any franchised Acura dealer.

Acura is recalling 76,253 2004-2008 Tsx vehicles in salt-belt states because deicing materials carried in on the driver's footwear can soak the carpet and corrode the engine control unit. That corrosion can stall the engine and raise crash risk; the dealer repair will be free once Acura makes it available.

What's wrong?

The engine Electronic Control Unit, or ECU, in the 2004-2008 Acura Tsx is the computer that manages key engine functions. It reads sensor signals and tells the engine how to run, so the vehicle depends on clean electrical connections and a case that keeps moisture and corrosion away.

On affected Tsx vehicles in cold-weather states, corrosive deicing material can be tracked into the cabin on the driver's shoes. That material can soak the carpeting near the ECU, and the carpet is close enough to contact the ECU case. Over time, the case can rust or corrode. In recall 13V093, that damage can interfere with the ECU and cause the engine to stall.

There is no warning sign before failure. The issue starts around the ECU case and carpeting, so an owner does not get a clear driving symptom before the engine stalls.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific sedan is included.

What's the safety risk?

An engine stall can leave you without power when traffic is moving around you, which increases the risk of a crash. If your VIN is included, schedule the inspection soon and avoid delaying the dealer visit. Repair will be free at any franchised Acura dealer once available.

What should I do?

  1. Check your VIN to confirm your 2004-2008 Acura Tsx is included in this recall.
  2. Contact a franchised Acura dealer and ask whether recall number 13V093 is ready for your vehicle.
  3. Schedule the ECU inspection and waterproof-cover installation that protects the engine computer from carpet moisture and corrosion.
  4. Bring the recall notice if Acura mailed one, or give the dealer recall number 13V093 when you call.
  5. Drive with caution until the repair is complete. If the engine stalls, move out of traffic and call Acura Client Relations at 1-800-382-2238.

What happens at the repair

Once the dealer repair is available, an Acura technician will inspect the engine Electronic Control Unit, known as the ECU, for damage from rust or corrosion. If the ECU is damaged, the technician replaces it. The technician also installs a waterproof cover over the ECU to help keep deicing material and wet carpeting from reaching the case. Parts and labor are covered under the recall.

Frequently asked questions

What is recall 13V093?

Recall 13V093 covers 76,253 2004-2008 Acura Tsx vehicles in states named in the recall for corrosive deicing exposure. Materials tracked in on the driver's footwear can saturate carpeting near the engine ECU, corrode the ECU case, and lead to an engine stall. Acura dealers inspect the vehicle, replace any damaged ECU, and install a waterproof ECU cover for free.

What should I do if my 2004-2008 Acura Tsx is on this recall?

Check your VIN to confirm your specific vehicle is included in recall 13V093. If it is, contact a franchised Acura dealer to schedule the inspection and ECU cover installation. Reference recall number 13V093 when you call. Acura Client Relations is also available at 1-800-382-2238.

Is the recall repair free?

Yes. Federal recall law requires the recall repair at no cost, and the remedy states that Acura dealers will inspect the vehicle, replace any damaged ECU, and install a waterproof ECU cover free of charge.

What is the safety risk?

The safety risk is an engine stall. Corrosion at the engine ECU case can damage the control unit, and a vehicle stall increases crash risk. If your VIN is included, ask the Acura dealer whether the vehicle is safe to drive until the inspection and repair are complete.

What if I bought my Acura Tsx used?

The free repair still applies. Recall coverage follows the VIN, not the first owner. If you never received the April 2013 owner notice, check your VIN, then call a franchised Acura dealer and reference recall number 13V093.
