There are 1 owner-reported fuel system complaints for the 2015 Lincoln Navigatorin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
While driving the Lincoln navigator with only 96,000 miles, it chugged and rapidly reduced power, forcing me off the road. It happened 3 times in 2 days while I was on vacation at the Wisconsin dells. The Dealer said it was "throttle actuator failure" after the test was run. I replaced throttle body and gasket at the dealer for $425.10 on 07/27/2021. This should be part of a recall!! We could have been killed from the sudden loss of power, and all the traffic behind me that had to suddenly stop. It was very, very, scary. It came out of nowhere, with no fore warning. I had no idea what to do.
