Doing a bit of venting. I have a 2021 AT4 2500HD diesel. My drivers side head light started to act like a strobe light. I couldn't drive at night without giving the drivers coming at me or in front of me seizures.
So I took it into the dealership and found out that my entire head light needed to be replaced. Oh it gets better, they found a light out on the passenger side also, so they need to replace that one also. I was quoted over $3,000 to replace both. Evidently you just can't replace a bulb like the good old days. You have to replace the entire assembly. Each head light runs about $1,400 (yes you can buy online for cheaper, but i'm not a mechanic), then add in labor and tax and just like that you have a grand total of $3,485. Of course this isn't covered under warranty or my extended warranty. No damage to the head lights, no water damage either. I thought these LED lights would out last the truck, what a joke.
This has to be the most ridiculous repair I have ever had to pay for. How does GMC think people can afford $3,485 for head lights! The family really didn't want Christmas gifts anyway!!
