What happened to the yukon a/c issue happened to me. What would it take to make sure the sierra has the same recall as the yukon? "yukon and yukon xl vehicles, may have a condition where thermal cycling on the combination transmission fluid/oil and ac condenser cooler creates a crack that may allow refrigerant to escape. This condition consequently may deactivate the ac system which may cause potential customer annoyance. ".
My 2015 GMC Sierra 1500 (approximately 45,000 miles) had a defect that caused the ac system to crack and leak refrigerant, lose pressure, and fail to properly function. When I took my vehicle to a certified gm service center on 4/11/19, three other similar vehicles (make/model/year) were experiencing the same issue. Upon conducting further research I found that this issue is widespread amongst similar year GMC sierra and Chevrolet silverado 1500 pickups. So much so that some areas are experiencing ac condenser replacement part shortages. My vehicle was no longer under warranty and gm refused to assist with the over $1,200 repair bill.
Like so many others, my truck is not very old and has been blowing hot air for months. It appears to be the same condenser issue as reported by hundreds if not thousands more. After discovering this is chronic issue and ac delco * discontinued the original condenser * issued tsbs for the condenser which include a bracket to help prevent the issue (TSB pit5331 / oct 2014) (TSB pie0340 / may 2015) neither of these were either applied to my vehicle or were not effective in preventing the issue. It seems obvious that this is a defect in materials and workmanship based on their issuing of these tsbs and failure to recall these vehicles under warranty. They've apparently operated a blatant "let's wait and see" campaign, hoping those of us that didn't catch this under warranty will fall out of warranty as I have. Several law firms have initiated class action suits against gm in regards to this, but it seems like that's a good chance to get lawyers rich and not get my truck fixed, or get a check for $9. 99. . . As a summary - my truck began blowing warm air last fall, but I didn't recognize it as an issue as the weather was also turning cool and I wasn't using the a/c. Ac/delco and general motors knows this is chronic and avoidable issue the faulty parts have been replaced when the products fail under warranty no effort has been made to replace the knowingly faulty parts.
Ac condenser had to be replace due to leak. Faulty design & installation. Gm already recalled 2014 models with the same problem. Condenser line bracket mount does not allow the line to flex, thus making crack in condenser. Repaired by the dealer at a cost of $775. 61.
