I have a Kohler 30K propane. It's been nothing but trouble from day one. I was just checking. We installed it back in 2010. The unit was defective from the get go and the alternator needed replacement just to get her to make power. Every year or two it needs brushes or fuel pressure regulator. Luckily I can repair it myself. Gen techs are both expensive and the ones I met, incompetent. The brushes don't wear out. They overheat to the point the wires connecting to them fall out of the brush. I always keep a spare fuel pressure regulator and brush set around. It's looking like brush supply is getting scarce. I might need to find alternative brushes. Keep in mind, it runs the exercise cycle once a week. Otherwise we barely use it. It has 400 hours in 14 years. The longest it's run making power was a week. Maybe this is par for the course. I bought Kohler because of the reputation for reliability. In hindsight, I probably should have paid more for a diesel generator. PE ruins companies. They buy them up, load them with debt, then sell new stocks to rubes. Then they bail and leave the now heavily indebted company to sink or swim. More on reddit.com

As a general rule, your best bet is a local dealer. Obviously exceptions, but more often than not you'll get better service if you bought the machine there

It’s not we bought a 60kw generac and it was the worst experience in my whole life. It worked once on test start did all the load testing thought great. Then about three weeks later a hurricane was possible so i went to check it and a red light was on. So i called the installer who has installed 100s by the way and he looked ran some test got the code sent it in they sent a part that didn’t work. So they sent a complete wiring harness that didn’t work mind you the installer is a electrician 3 generation he is not stupid. So this went on for months. The claims lady was terrible wouldn’t answer emails literally would take 4-5 days one time it was a week and half she said she was on vacation. I’m thinking you are so unorganized as a company when one person is out the customers calls and issues just go unanswered it was ridiculous. Then after about 5 months i kid you not still not resolved they had basically replaced every went over it multiple time with genecrap on the phone nothing. I told them look i paid i did my part i gave you money for a working unit it’s not working so give me a new unit i need this for my business i can’t have no power i cant operate with out it. She said that’s not how the warranty process works. I told her if you bought a car and for five months you couldn’t drive it and dealer couldn’t fix it and you couldn’t drive would you think that is an acceptable answer. Sorry about your luck thanks for you money we gave you a bad car but you will have to wait. Who in the world operates like that. The installer and dealer. Was so embarrassed and upset with them he literally out of his pocket gave me the refund then she said that not how they operate she will have to close the case they never refunded him he sold it at Richie brothers for a loss after taking it to his shop and trying to get it to work he even called im a engine specialist to see if they could figure it out. Generac is a complete joke I was understanding patience and they treated us like garbage i did yell at them on the phone till month 4 i wasn’t rude till that point but i went off the wall when i did just a complete disaster all around I would never ever wish that company on my worst enemy.
