355HP Z71

I have a 2014 regular cab Z71 and I have smelled coolant and noticed a slow drain from the reservoir tank for some time . I didn't receive the letter that some of you did and my dealership service dept. said there was nothing on this issued for my truck according to my vin. I gave her the TSB number that was on this thread . She called today and said the radiator was leaking after a pressure test and that they replaced the radiator and thermostat . So for everyone who has smelled coolant but didn't get a letter you prolly still could have this issue.

I been using the OEM's with no issue . I change them every spring and a coat of Rain X every couple months and I'm good to go !!

I think LD stands for light duty ?

If for some reason it needs replaced I bought the extended warranty if for some reason they won't cover it under the TSB.

Ok .. Thanks Ron .. Im going to bring this up next time I take it in for a oil change . I have noticed the coolant smell for some time now and it seems like the over flow bottle is slowly going down .

I am a little confused . In TSB # 15829 It says it covers 2014 models and in the other TSB #PI1513A it says the 2014 are not covered ?

Does anyone know if all owners of a 2014 will be getting a letter or just certain VIN's ?

If you have onstar they use to be able read the code also . I think the service message has to be showing on the DIC.

I had this promblem about a year ago . It happened to me twice . The first time it happened the message went away the next time I started the truck up . I had the dealer check it about a month later when I had it in for a oil change and the code in computer was gone so there was nothing they could do . A few weeks later it came back on again so I took the truck in the next day and this time they were able to get the code. They replaced the transfer case actuator sensor and I havnt had a issue since.

nice pics ....love my topaz blue Z71

I had this happen to me one time . I used the remote start to start the truck and the wheel unlocked and the key turned .

Today it was 65 degrees here in Ohio and my service 4 wheel drive light came on . I was driving down a road going 45 in 2 wheel drive of coarse when the light came on . I decided to see if it would switch to auto and it would not . I came home stooped the truck and then restarted it and no more light . It also switched to auto when I took it for a drive . Still going to call the dealer tomorrow !

Just started to change the battery in my key fob . Did it just like it says in the owners manual . Used a coin to pry the cover open and in the process both of the plastic tabs on the top of the cover broke off ! ! These fobs are nothing but cheap plastic !! Going to call the dealer tomorrow and see if they will replace it under warranty.

I have have LT rated Bridgestones and the sticker on the door says 40 psi .
