Sorry, thought you were asking about tire pressure. On the Lariat, it is on the left side display (you have to scroll down to get to it), but it depends on which level of Ranger you have. Not sure on the others, but you can find where to look under "Information Displays" in your owner's...
I had that problem with my Colorado and finally installed a simple 3" long cabinet door handle over it. Never happened again and it looked factory installed. A terrible design since they also don't have a light on the dash to tell you that you are in 4wd.
Generally means you run the transmission in a higher gear than it should be in. Common in manual transmissions when you fail to downshift and the engine can't keep the rpms up for the load it is encountering.
Have never noticed either of those problems. Brake pedal feel is just fine and no issues with transmission down shifts. Have you had your dealer look at it?
Drive it. It's a truck and intended to be driven in all kinds of weather. Take it to a car wash to clean it and be sure to spray off the area inside the wheelwells to get rid of accumulated salt.
Ah, the good old days of the 1950s and 1960s when add-on toilet paper filters were all the rage. I think you can still buy them. Wonder if scented Charmin would make your oil smell better?? :)
You should be pissed. Warranties are a big money maker for dealerships, and you have to wonder how many get slipped past buyers who aren't paying attention with all the excitement of buying a new car.
