  1. Wonderful, well I'm still having issues, ecm and harness are being replaced, it's being considered a different issue since something new is being replace, I guess I'm going to have to get a lawyer because they are insisting on no buy back if this fixes the truck which has what has been said the last 3 times
  2. That's the problem, I've only made 3 payments on it so whatever they offer me is going to put me in the red. I just want a new truck that's exactly the same. I love the sierra other than the engine I've got
  3. Dealer has my truck and is getting with gm on instructions on diagnosing and repair, which is what they have done the past few times because it seems to be a technical gremlin. I also contacted my service advisor at gm and they are gonna start paper work for either a buy back or trade in, from what I can tell gm isn't too great about buy back prices even though I got mine on sale. I'm also concerned I won't be able to get another one like it for the price I bought it.
  4. I was literally supposed to come to terms on some kind of reparation for all the stuff that has happened today. That's has now changed. I've been in contact and have had a claim with them since the 2nd week of ownership. Now I'm gonna be asking for a buy back no matter what happens. The truck has been proven to be unreliable time and time again. Something tells me im about to fight with them
  5. I've had issues with purge solenoid, fuel pump, filler neck, and I've had dfm solenoid #3 replaced, all my lifters, and after 2400 miles I'm at 6600 and the check engine has been on for 3 days for emissions and I've been having the check engine flashing for misfires during the time period. It was off this morning but I'm taking it to the dealership today. Had it since may 14th and this will make the 9th or 10th time in the shop. It's only been in my possession about a total of 3 or 4 consecutive weeks this last time. Before that it was in the shop every single week since the week after I bought it
  6. Sector, I opened a case with gm because I had other issues but after the 2nd time I brought it in for the mifire and they couldn't replicate it they opened a case with gm and got help from their support. First time after that they had it for a week and they couldn't duplicate it and the second time I brought it in a couple days after that gm support told them what to replace I guess.
  7. Hopefully I'm done dealing with this problem for awhile but mine just had to have a dfm solenoid replaced and I've been battling this issue since 800 miles and I'm at 4300 now.
  8. Took back to dealership after another misfire. Tried to replicate for a week. They put a 150 miles on my truck. Got it back and over the weekend it happened again. Took it back monday and now they are waiting on lifters and a dfm solenoid at 4100 miles and I've been in a loaner for almost 2 weeks. This has been the worst experience ever. Dealership has been awesome but gmc hasn't been that great.
  9. Lifters and dfm solenoid for cylinder 3 are being replace in my 5.3 10 speed currently at 4100 miles
  10. 3rd Time was the filler neck, it had a crack Less than 200 miles later check engine for misfire again, code not present when taken to dealership, they've opened a case with gm and I have a claim open waiting on response. 4 times in 4 weeks.
  11. Well issue the second time was supposedly the purge solenoid, it was replaced. Half a tank of gas later at 2900 miles misfire code again and now at 3000 miles the check engine light is on solid. 3 times in 3 weeks, misfire codes every single time and evap system issues.
  12. I have a 2020 gmc sierra sle 5.3, I bought it may 13th. Starting at about 800 miles check engine light would flash for a minute or two and then go off, this occured every 300 miles until I got in one day around 1500 or 1600. Check engine light stayed on. Called the dealership and took it in was throwing misfire codes, the diagnosed it as fuel pump module reset the codes and ordered the part and sent me on my way. Come back in and had it replaced when the part arrived, well now fast forward to a tank and a half later and now the check engine light is on for the evap system/gas cap, and fuel pressure at 2200 miles. Right at a week from the time it come out of the shop. I've been extremely happy with the truck but I can't believe I'm going to have to find time to get it in the shop to be looked at and fixed again. I'm at wits end already. Anyone else having these issues?
  13. 2020 gmc sierra 1500 sle. Check engine light was flashing and turning off every few hundred miles since new. Check engine light came on and stayed solid today, took it to dealer and sat for 3 hours, they cleared the code and are waiting on a fuel pump module to come in from gm
