Our 09 with the 4 cylinder had some noise as well. When we traded it in at over 80,000 miles, it was still making the same noise. Just perform regular maintenance and the engine will outlast the car. I didn't mind the noise. Just drive it and don't worry about it. You do have a good vehicle that you can drive for however long you like if properly maintained.
Welcome to the forum!!
You bought a big vehicle with a 4 cylinder engine. It is what it is. Aside from dropping a bigger engine into it, there is practically nothing you can do about it. Bolt ons may gain you a few HP here and there, but nothing that will make a noticable difference.
If it aint where it used to be (above the glove box on our 09) it does not exist. They did away with it. Never worked for us anyway. Just became another glove box (or junk holder box),
If you want OEM, you gotta go Dodge, either from the Dodge dealer, website or junk yard. Wiring harness is probably there, but you would need the lights and a new switch. Dealer would probably have to enable them as well.
No, that is a false statement. The tires are not "cheap, crappy chinese" tires. They are major brand name tires made to the manufacturers specifications to obtain a soft ride, i.e. soft compound and they do wear out quicker than the tires you and I can get from the tire store.
I think the bluetooth is advertised if it has a certain trim level. I did my research before my purchase. I knew that by looking at the steering wheel if it had bluetooth or not. As stated, installation of bluetooth after the fact will cost you.
