Good evening fellow Mack enthusiasts. I am not sure if anyone cares how my new Mack is doing, but for those that might, here is my update. Let me start by saying between my 379 pete with a c15, my 660 kenworth/studio with an ISX, and my new CXU/505C+ (all ordered new), this Mack remains my favorite so far. The highrise sleeper isn't as deep as the 86" was on my KW obviously, but I feel like I have twice the room due to it being so much more useable. The truck rides nice, it's quiet, and performs beyond my expectations for a 13 litre. I personally love all of the interior illumination @ night. Headlights are fantastic too! I was kind of ticked when I found out HID wasn't an option when ordering this truck. I had them on my kw. These are as good, probably better, so no worries there. As far as issues with the truck, I have had 1. Around the 10 000 mile mark, I was 50 miles North of Vegas and I got a cel light come on. I drove straight to Mack/Volvo in Vegas. I walked in and explained I had a 16 Mack with 10 000 miles on it with a check engine light on. This needs to be fixed now. The service writer appreciated my frustration and had a tech on it in 20 minutes. It was discovered that the module that runs the 7th injector was bad from factory. It was actually trying to do its first regen, didn't reach temp, and failed. So it threw an engine code. They changed the module, ran it through a regen, and I was down the road in about 3 hours. Start to finish. The truck hasn't missed a beat since. It's lifetime fuel economy is 7.39 us mpg from new, and it's 30 day average is 7.48. It's still going up. Anyhow, that's about all there is to tell for now. I will check in when there is a few more miles on the clock. As of now, very happy I ordered a Mack.
