This truck has went back to shop at mack shop. So we will see what they say. I've asked around and every new mack we have from 2012 to new ones like mine. Have spent as much time in the shop as in service. This has been a real let down for me being a fan of Mack trucks.

2013 granite. This thang has been a headache. Third time goin to shop since may( just got it in May) has only 10000. Anyway! Any ideas of what's happening? It started this all at once. No radius turning left, but turn on a dime right. No visible leakage, nothing appears broke, or loose. This dog is so frustrating.

I didn't think to check boost pressure, truck has been sent to the dealer this morning. They didn't change a thing last time it was there. I believe they just reset the light. Luckily it's under warranty. Thank you for ur response. I will now know what to look for and ask about when I pick it up.

My 2013 granite has thrown the codes spn102, FMI14, SPN1127 FMI 18. Was sent to Mack to fix one week after finally getting it back it has done it again. What do they mean, the shop manager couldn't even tell me. Yes shop manager. Could these codes cause a power loss?

What are the fault codes spn1127 fmi18, spn102 fmi 14? Thanks for y'all's help

2013 with plow attachment. I just got it 2 weeks ago so no plow or bed spreader on it yet. Sorry!
