Want to purchase 2015 GMC Yukon SLT with 92k on it. What should be my concerns and what should I look for? Is it safe to buy?By Paulnyc
What could me the main problems and issues I should look for ? Thanks for the input
Hey guys, new to this forum. Recently purchased one of the dream trucks of mine, 2014 Sierra Z71 4x4 5.3l. Which I was finally able to afford lol, bought from a local dealer with 88k miles.
Prior to purchasing I test drove it, checked the history and maintenance records from GMC. All seemed well, purchased it and few days later while driving home on the highway cruising about 60-70mph, I began noticing a really loud sudden vibration that would come and go every few minutes (feels like it’s coming from underneath the truck not sure), lasting about 5 seconds. Even around 20-30mph I notice some shaking. Seems to be shifting fine, drives pretty smooth other than these vibrations that are coming and going. I just don’t know what it could be. I didn’t notice it during the test drive, just my luck, hoping for the best. Any opinions are greatly appreciated, I attached a video as well of the sound.
Hi! In April, my Yukon was throwing codes P0172 P0175. Local GMC dealer in Louisiana "fixed", by replacing some sensor. Traveled to PA, codes came back on. Local GMC dealer fixed by replacing BCM, body control module in June. Now my check engine light is back on! Power train Warranty ran out 2-3 weeks ago. Also had extended warranty, which also ran out at 5 years, which was Sept. Code onstar says its throwing now is P0430, all of the codes from I can find are related to exhaust system. My question is are these 3 codes related??? Could this be something they will have to fix under warranty, given it's related and has been worked on several times?
If not, what does this mean? Catalytic converter bad? Help! My husband is being laid off in the next week. So, obviously finances are tight. Yes, obviously itll be fixed regardless, just trying to plan and cut back elsewhere if needed. This has been a great vehicle! As luck has it, trouble starts when warranty runs out.
Really wanting to trade, but waiting on new body
Adding mileage if matters, 91K
Hope this helps anyone that runs into this. My original battery died and I changed it out yesterday. After the change my AC was not operating correctly. I surfed the forums and found all sorts of fixes like pulling fuses and disconnecting/reconnecting the battery. None worked. I then notice that the outside temp on the intellilink screen is showing 36 degrees. Figuring it reset to Celsius (I’m in Texas so that is a logical centigrade reading for us) I checked settings and found it was set to F.
Buried in a forum about calibrating the temp gauge I found a GM service bulletin that says after a battery dies you need to drive the car at least 5 minutes over 20 mph for the temp gauge to calibrate; or let the car sit off for 8 hours. I drove the car down the highway and this worked like a charm.
When the outside temp is showing 36 degrees, it is basically telling the ac compressor not to come on and sending heat to the car. Not a lot of fun in 95+ heat in Texas.
On a side note why why is there no documentation that this is the norm? I called the dealer to have a girl laugh at me and tell me the car “has” to have a lot of things reset after a battery swap...and they want $155. Which was basically corrected with 5 minutes of driving.
