The Dealer has had my 2017 Chevrolet 3500HD since the 6th. The truck was put into service in 11/2017 and now has 18,000 miles. It is still under the 3/36 bumper to bumper warranty and has 5/100 power train warranty. They're replacing a headlamp on the passenger side that had apparently shorted out and was causing electrical issues. My backup camera was blurry and my mirror turn signals were acting funny. Basically the passenger side mirror turn signal would stay dimly lit and then blink along with the left turn signals when they were on. It would do it anytime the headlights were on, even with only the day time running lights on. If you turned off the headlights everything would work perfectly. They are replacing the coolant reservoir. I was getting a persistent low coolant light, but the level has always stayed full. I had to add some when I first got it, but the level hasn't dropped since I topped it off 11 months/ 7,500 miles ago. They claim it was leaking and needed replacing, so I didn't argue, but I thought only the sensor had died. Maybe it had a slow leak I couldn't see, but I've put 400 engine hours on it and it hasn't visibly dropped in the reservoir any. Whatever the case, they are replacing it and that's good enough for me. Lastly they are replacing the transmission cooler lines. Mine haven't rubbed through yet (it's a common problem, there's a TSB) but I explained to them that I tow heavy and often and that I didn't want to have to worry about them rubbing through while I'm hauling and having to figure out what to do with my loaded gooseneck. They agreed to replace them under warranty/per the TSB. I love the dealer that I'm using, they've been great to work with. The service advisor even came out and sat in the truck with me and let me show him what my truck was doing with the electrical issues related to the headlights. So, I'm a big fan of this dealer... we've bought 2 trucks from them over the last 3 years. I however am not very happy with GM at the moment, I've been without my truck for nearly 3 weeks while the dealer waits for parts that can be replaced in less than a day. I didn't ask for a loaner when I took it in because I thought they would only have it for a couple of days max. I took it in for an oil change, a recall and what I thought were a couple of minor repairs. At this point they've had it long enough to have rebuilt the engine. I talked to the dealer a couple days ago and they have completed the coolant reservoir replacement but they are waiting for the headlamp and trans cooler lines. The service advisor said that the parts are "special order status" and doesn't have an ETA on them. I think I'm gonna call GM corporate on Monday and express my frustration, this is ridiculous. I'm not too hard to keep happy, but I also expect a reasonable level of service from a company that I paid $60,000 for a pickup truck less than a year ago. I'm hoping for some kind of compensation for my trouble but not really expecting them to offer anything. Some extended warranty would satisfy me, not betting on it though. Does anybody know what GM pays per day or for mileage for a loaner/rental when you are having warranty work done? If I had this to do over again I would have demanded a loaner from the beginning, I had no idea this was gonna take so long. If I was using a dealer loaner or a rental GM would be paying for it, would they not? I didn't ask for one because I don't mind being without a car for a few days because I can walk to work, it's less than a mile. I've thought about trying to get a loaner, but I figure I should hopefully......maybe get it back soon. It's a 130 mile round trip back to the dealer to pick one up if they have something I can drive. Even if I had a loaner it wouldn't help me much, I bought a 3500 HD because I need a 1 ton truck with a gooseneck ball to tow with. I can't do what I need to do in a 1/2 ton truck or an SUV. I've been borrowing my Dad's Duramax when I need to tow and my sisters SUV when I just need a car to drive. I think they're getting as tired of it as I am, but what can you do? I think I'm gonna make a call to GM corporate tomorrow and complain. I paid $60,000 (traded my old truck and paid the remaining balance in cash) for this truck and have been walking to work and bumming vehicles from family members for 3 weeks, it's getting ridiculous. I could understand if I had a major failure and it required tons of labor.... but this is a couple of relatively minor repairs. Am I out of line to feel like they owe me something for this ridiculousness? It's not my fault, it's not the dealers fault... it's GM's fault. The dealer can't install parts that they can't acquire. I wanna hear what you guys think and what you would do in my situation. Thanks in advance.
