What's wrong?
The automatic transmission oil cooler pipe assembly on the 2010 Mitsubishi Galant is a metal line that carries automatic transmission fluid between the transmission and its cooler. That fluid helps the transmission operate at the right temperature and pressure while the car shifts. The pipe needs a protective plated surface because it sits under the vehicle, where road water, salt, and grime can attack bare metal.
On affected Galants, the pipe assembly did not receive enough plating to protect it from corrosion. As the metal corrodes, the pipe can wear through and form a hole. Once that happens, automatic transmission fluid leaks out instead of staying inside the cooling circuit. Low fluid can interfere with transmission operation and leave visible fluid under the car.
There is no warning sign before failure. After a leak starts, an owner can notice reddish fluid on the ground, a burning fluid smell, or a change in how the transmission shifts.

What's the safety risk?
Automatic transmission fluid in the presence of an ignition source creates a fire hazard. Keep using the 2010 Galant cautiously, and schedule the inspection soon so a dealer can check the oil cooler pipe assembly and replace it if needed. Repair will be free at any franchised Mitsubishi dealer once available.
What should I do?
- Check your VIN to confirm your 2010 Mitsubishi Galant is included in this recall.
- Use Mitsubishi's owner notice if you have it, then contact a franchised Mitsubishi dealer for repair timing.
- Schedule the automatic-transmission oil-cooler pipe inspection that checks for insufficient anti-corrosion plating and ATF leak risk.
- Reference recall number 10V066 when you call the dealer.
- Avoid parking near ignition sources if you see transmission fluid leaking, and do not ignore fluid spots under the vehicle.
What happens at the repair
At the dealer, a Mitsubishi technician inspects the aft automatic transmission oil cooler pipe assembly for insufficient anti corrosion plating. If the inspection finds insufficient plating, the technician replaces the aft oil cooler pipe assembly with new parts that have the correct anti corrosion plating. The dealer repair will be free once available, with parts and labor covered under the recall. Mitsubishi's recall instructions also list Mitsubishi customer service as the contact point for repair timing.

What should I do if my 2010 Mitsubishi Galant is on this recall?
Check your VIN to confirm your specific Galant is included in recall 10V066. If it is, contact a franchised Mitsubishi dealer to schedule the inspection. Reference recall number 10V066 when you call. The dealer replaces the oil cooler pipe assembly for free if the inspection finds insufficient plating.
Is the recall repair free?

What is the safety risk?
The safety risk is a fire hazard from leaking automatic transmission fluid. If corrosion creates a hole in the oil cooler pipe assembly, fluid can leak. ATF near an ignition source creates the hazard described in recall 10V066.
What if I bought my 2010 Mitsubishi Galant used?
