What are some of the lincoln navigator electrical problems?

Some potential electrical problems in a 2020 lincoln navigator are due to a dead battery, bad alternator or blown fuses.

2019 and newer Navigators electronics are constantly drawing power. Over time this can cause a dead or sulfated battery cell which leads to component glitches such as running boards acting up, screen blackouts etc. The cure is installing a good battery tender such as the OptiMATE 6 which desulfates and maintains battery to 100%. Hardwire battery terminal leads with extension cable and feed to easily accessible point for ease of daily use without lifting hood. Since installing over 1 year ago, I have not had a single issue. Seems the electronics are very sensitive to weak batteries.

I have a 2020 navigator. We have had major issues with this vehicle. Transmission problems started at 2500 miles but despite all of the alerts inside the car, they never registered and the dealership always told me the vehicle was fine. The gears would not shift properly at important times, but it was random—like accelerating to get on the highway or trying to pass someone on a dotted yellow. The problem finally showed up consistently at 34000 miles and the transmission completely was replaced. I was told by the dealer it was a known issue. It is also a major safety issue. The electrical problems began straightaway. That entitled system was updated and tweaked twice before they fully replaced it. 15,000 miles later and it is struggling again. If I am on the phone and get in the car, plug my phone into the jack immediately after start and put it in reverse, the screen goes black and won’t fix it unless I turn the car off for several minutes and restart. It had happened about 3 times in the past two weeks, but I have literally only had my car back from the transmission fix for a few weeks (and they had it for 4 weeks), I wasn’t rushing back to the dealership. This morning I got in, put my foot on the brake and pressed start, and all the interior lit up as usual, the music even started playing. But the engine didn’t fire. So I pressed the button again. It acted as if I had turned off the car and the seat started moving back. So I pressed it again. The screen went black and then a message came up that said “turning off ignition to preserve battery power” with a timer bar under it. I pressed start over and over. No clicking noise that would typically indicate the battery is bad. Just a car that won’t do anything. Seems electrical again. I loved this car and was so excited to get it. I never wanted a large car but if I had to drive one for the kids, this was the only one I ever wanted to have. Now I can’t wait to get rid of it. The car has been in the shop for something broken every month since July and they’ve had to keep it a week or longer twice because parts were back ordered. My specialist always works me in and gets me to the top of the list for work, but it is still a terrible inconvenience. Don’t buy one.
