Question about temperature and 4wd
Last week I bought a 2014 trailhawk, fully loaded, tow package etc. Living on long Island, we spent a lot of time at the beach. This car is really impressive on the beach. But ad soon as I start driving in the sand, the temp shoots up to 220 (my older Chevy ran at 210 no matter what I was doing). The car also will no shift higher than second gear (2000 rpms), unless I put it in manual shift mode and shift it myself. A few days after I bought it I brought it in for the same complaint, as well as the information screen flashing with no picture. They replaced the master cylinder and and ABS sensor that they said was causing it not to shift correctly. What is a normal temperature and should it be shifting higher than second?
