Its been a frustrating couple of weeks. Week before last when towing my camper for a short vacation the CEL pops on. So I immediately hop on the My Chevy app and schedule a visit to the dealer the following tuesday.

 

Tuesday comes and I go to drop off the truck and get my loaner to go to work. So there is some issue where the apt scheduled on the app doesn't show up in my dealer's system and they don't have a slot or loaner for me. But they work me in but by this time the shuttle leaves and by the time I get to work, my boss is mad, I'm mad.

 

So the code ends up P20EE, NOx sensor bad. They have to order it in. Manager apologizes for the scheduling issues and says he will have me a loaner. I get there and you guessed it, service rep has no idea whats going on, they have to dig up a loaner..... an hour later I go home!

 

Truck is to be ready at lunch but no go, still working on it. Pick it up on the way home and things seem ok with it.

 

Two days later, light is back on! UGH! I have a scanner so I check it, now its P204C, Redu​ctant pressure sensor circuit low... So now I am back in on Monday.

 

I am starting to think I should have bought something else.

Hang in there. We've sold 5 of these new ones, only one truck has come back but he has a communication error somewhere. The other ones no issues. One guy tows boats for his customers (big and small) and put it to work day one and has only done an oil change so far.

 

There was a couple bulletins for ECM reprogramming for some issues on them, but I don't recall if they pertained to the codes you had.

For a truck with less than 2000 miles on it and costing 70k. I am a bit more than just frustrated. I love the truck otherwise. And part of my frustration is with my dealer. I've had great service from them in the past, so I am hoping this was just an "off" day.

You could have.. but what makes you think you wouldn't have problems with something else? Regardless it sucks though!!

A quick update, I dropped it off at 7:30 this morning, When I did not hear anything by lunch I figured this was not going well. So at 5 they give me a loaner and tell me the technician has been at it all day, running tests, then calling GM, GM telling him to run more tests.

 

I am due to tow my camper this weekend, the mrs is not going to be happy if we don't have a truck.

that's ok. They're never completely satisfied anyway.

So the technician talked to GM, GM thinks a bad DEF wiring harness caused the earlier and the current faults. GM overnighted a new harness.

 

Good to hear. Typically if a tech gets a hold of GM (they call their Technical Assistance group TAC), the folks at TAC get calls throughout the nation. Lots of times, they have an answer right off the bat as they will have had a similar or exact same case at another dealership somewhere else. They have all sorts of info, from other similar problems at other dealers, to engineering issues, production line issues, etc. TAC is full of some smart folk with lots of data.

More bad news. First the harness did not make it in today but they think it will be here tomorrow in the AM.

 

But now they are backing off how long it will take to install it. They are now saying it may take 1-2 DAYS to install the harness.... I was told it was a DEF harness. Does this sound reasonable?

 

Its too late to cancel my camping reservation this weekend. I'm out $120 for that if this all falls through.

 

Do I have any recourse to ask for a truck capable of towing as a loaner?

If its one of the two harnesses that are in/on the tank, its not a 1-2 day job. Now, if they were trying to get the engine harness side plug that goes to one of those DEF harnesses, then yes its a day or two. If that's the connector they needed, they have to change the whole engine wiring harness.

 

Is your trailer conventional hitch or a 5th/goose?

If it is the main harness, do you know if this means pulling the cab up? I had someone tell me that...

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      New tires are on, Cooper Discoverer Road+Trail AT's in 235/75/15. $100 per tire, after $10 AAA discount. Plus install ($100), disposal fees, and taxes.   The new tires ride nice. Catch 22, new tires, I love it again! But I feel like I've been through the wringer with this rig, and maybe I don't need this kind of headache right now. Wait until tomorrow, I'll probably love it again and keep it another week.   Never a dull moment: Got a CEL driving to the tire shop, P0172 bank 1 too rich. Oh lordy, really? I've been enjoying an emoji-free dash for too long, apparently. I popped the hood at the shop and I think there was a vacuum leak very close to the intake. Cleared the code and put a bunch of miles on it going home, code never returned. My fix was zip-tying the line on the vacuum reserve ball because the hose won't stay seated. It's either that or the fuel pressure regulator has an issue again or an injector is leaking. See why I'm getting tired of this one?!   In the gas price thread I recorded 19mpg on the last tank in fairly mixed driving and some higher-speed highway (70). I also don't have the lower engine shield installed right now, and that would help with diverting a lot of wind underneath the truck.   Not too long ago, a green '96 4-door 4x4 came up for sale with less than 1,000 actual miles. There was a story there but it was real, and the place wanted like $25k for it. Would be fun to have a NICE example of one of these, but not too nice. The joy is driving them.   That's it for a while...family and social stuff all weekend, no time to play with my Hot Wheels in the garage for the next couple of days.

      $5.19 after Kroger discount for 87 today. Moses!   Somehow I've already put 560 miles on the Blazer with the last tank clocking 19mpg.

      Oil dipstick

      By Stu Katz · Posted

      I have a 91 GMC SIERRA 1500 4.3 liter. My dipstick broke. Can someone tell me how long is the oil dipstick. Local Part stores do not stock the oil dipstick. If someone can tell me the length. I can match up an aftermarket one. Thank you.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Assembling a Word Puzzle   A sentence in a famous sermon says:    “Happy are those conscious of their spiritual need, since the Kingdom of the heavens belongs to them".   Forget it was a sermon and forget its religious nature. Assemble the puzzle. What did he say? I'm only going to unravel the part underlined.... Keep it simple and out of the ditch. It's a word puzzle not a religious class. I'm not writing a book. Okay..   By saying that people conscious of that stated need will receive; the implication is that there are also people that are not conscious and thus deprived.   But this one sentence also says that ALL people have this need, not just the ones aware of it.   NEED will try to lead you to satisfying it. You're thirsty, you seek water. You're hungry, you seek nourishment. You're cold, you find cover. Lack of awareness is a choice. So when he says "conscious' he isn't saying simply aware but aware and active in satisfying that need.    That's allot of information for eight words. This man knew how to craft a sentence...   Give that some thought the next time you read an advertisement or a book.

      Gas fill door

      By snowblind · Posted

      My gas fill door does not stay closed. Not sure what happened, but it works its way to about a inch open every trip. Need a fix to this. 2020 Silverado 1500.
