Ford Expedition Galvanic Corrosion, Image: Carcomplaints

I am not sure if you have looked at this before, but there are aluminum issues Ford has had on several vehicles. I discovered it after I purchased as Certified Pre-Owned 2016 Ford Expedition XLT 4WD with the upgraded option package. It had over 38,000 miles on it when I drove it off the lot. That number will make a difference later on. The biggest issue though is galvanic corrosion under the paint many customers are experiencing.

The tailgate/hatch and hood are made of aluminum on several years of the Ford Expedition. Within a few years the paint starts to bubble. I read about it online, and contacted Ford. I got a call back from a “Regional Manager” from Ford. She blamed ice on the roads. I pointed out I am in California, and she said oh, then it is salt air from the sea. I then further pointed out I was in Sacramento. She informed me my vehicle did not qualify for a buyback. I said I just wanted it fixed. She said the five-year corrosion warranty didn’t apply to this unless it corroded all the way through the panel. It was covered up to three years/36,000 miles, and not one of the things extended with the Certified Pre-Owned 12 month/12,000 mile. The vehicle was driven as a dealer exec vehicle from about 27,000-38,000 miles.

A couple days later, I was told Ford would cover repainting it. After I dropped it off I found Ford TSB 17-0062, which says it should be replaced, not repainted. It took over a week because they found more extensive corrosion repainting it, but still repainted it after I pointed out the TSB. When I got it back, I had new damage (paint chipped on the hood down to the aluminum) and they have had it four more days now to fix that. I am concerned that one of the theories on this is galvanic corrosion due to dissimilar metal contamination in the aluminum. If that is the case, repainting will be a temporary solution at best. A solution that gets you further from the time when it is covered.  (Read More…)
