Hey everyone, I have a 2018 GT premium and I bought it new in Jan of 2018. Car has about 70,000 miles. Question, is this normal for the light output to dim over time? I have a 2017 Honda Civic Touring with LED headlamps and it has 117,000 miles and it much brighter than my GT, and does not seem...

Hey everyone, Need advice on what is possibly wrong with my 2018 GT (69,xxx miles). A week ago the CEL came on and I scanned it using FORScan and it showed code P0420. I reset it just to see if it pops up again and within a few days of driving maybe 60-80 miles the CEL came on today. I...

Hello, I dropped off my 2018 GT at Ourisman Ford Service Center ( Ourisman Ford of Manassas ) on March 30, 2024. That car is outside of factory warranty but is covered by Ford ESP. The issues the car was taken in was for 1) leaking coolant (turned out to be water pump that needed replacing...

Long story short, I took out the spare tire to do some work on the car and noticed the paint completely gone and exposed metal covered in rust at three different spots in the spare tire area. No idea what caused this as there is no standing water (pointing to a leak). Can this be repaired as a...

Hello, My 2018 GT has 57,000 miles on it. I have been using Pennzoil Ultra Platinum 5W-30 since the first oil change (about 3000 miles). I changed oil last time with PUP 5W-30 and filled it up where the oil level was touching the top hole on the dip stick. I wanted to see how much oil my car...

I tried many times to update my 2018 GT Premium 8inch with NAV using a SanDisk 64GB Extreme Go USB but no luck. I input my VIN number on Ford's website and it tells me that the latest version I can get is 3.0.20204 (Currently running 3.0.19205). I extracted the file into my USB drive (formatted...

Hey everyone, I was doing some general maintenance on my 2018 GT when I noticed the passenger side valve cover sensors (dont know what they are for, please educate) have oil accumulation around them. Looked on the driver side but did not see anything like this. Should I be concerned? I am...

Hey so its time to change the first set of tires since the car was purchased new in Jan of 2018. The factory tires are: Goodyear Eagle F1 Asymmetric All Seasons This set of tires has been good to me. Not a lot of road noise, decent grip in dry, wet and light snow. However, after 38,000 miles...

I have a rattle/buzzing sound coming from the bezel/trim around the digital cluster and it drives me insane as the colder weather is really making it buzz. I just don't know how to take it off and am afraid to break it if I pull on it wrong. Any suggestions on how to take of the trim without...

Hello! Last night I took my GT for some back road fun. It has been a couple of months since I had the chance to do so and to my surprise I noticed that the car was not making the power it use to. The car has about 27,500 miles and is equipped with the A10 trans. In Drag Mode, it use to chirp...

My car is a few miles shy of 25000 and as you can see from the pictures, the car is consuming oil. I switched from PUP 5W20 to PUP 5W30 at 23,300 miles and once I filled up the car with 10qts the oil level was at the middle of the hashed area. After approximately 1600 miles the oil shows at the...

Checked the oil this morning and it was about half way down from the top of the hash marks. Is this amount...

Hello, So I purchased a bottle of Redline SI-1 fuel system cleaner and when I tried to pour it into the gas tank using a funnel (tried 2 different ones), the additive just spilled all over. The little cover on the mouth of the tank flips back but another 3 inches in there is another flap that...

Interesting topic that is about a year old but relevant and an interesting read. https://jalopnik.com/why-expensive-oil-is-a-waste-of-money-1797241527 Keep in mind, this is for a 4K oil change and a longer oil change interval would reveal how higher cost oils outperform your cheaper oils...
