By S. Guinther on October 22, 2010
I am the proud owner of a well-maintained dead generac 16Kw generator with a whopping 72 hours of use, mostly exercise cycle time. The generac we originally purchased was unable to hold oil upon delivery, and was eventually replaced under warranty. Four years later during a brief power outage a couple of weeks ago our generac failed. The local dealer determined the rotor, the most expensive component to replace, had failed. If you do some research, you will find that this is a fairly common problem. We approached the manufacturer with a warranty claim, but, since their warranty was only two years, the best they were willing to do is sell us the replacement part at their cost, about $565 and leave me to eat the labor to install (including diagnostics to determine problem), another
$300. So, let's see, they are only willing to forgo their profit on a part that was engineered to last for 20 years and failed at about 20% of life expectancy, and is well-known to do so. Not wanting to throw good money after bad, we'll be buying a new, better, generator from another manufacturer.
I think it's likely you will be disappointed if you buy a Generac product as a long term investment, because as a company they are quite unconcerned with providing you with a product that will perform at all beyond the brief factory warranty. There are many better alternatives out there.

I live in NJ, and like most of the state, lost power during Hurricane Sandy.

We purchased a 17KW Generac in June 2012.
When we lost power during the storm, my 4-month-old Generac did kick in and we were initially happy campers. We were without power for 11 days. Every few days, we powered down the unit, let it cool, and checked the oil, per the user manual. After 9 days, the Generac failed. We were without power for the remainder of the period, about two days, enough to lose the contents of our fridge and freezer.

The repairman just left, he told me they are receiving many calls for the 14KW and 17KW units. He believes they have a design flaw where the spinning part can slide slightly along the axle, about 1/32 of an inch, allowing the spinning part to touch and wear down the brushes. He replaced the brushes and installed a spacer to avoid this issue in the future. I hope his jury rig works.

I'm dissatisfied when a 4-month-old unit fails after following the user manual recommendations. Wish I bought a different brand/model.

On August 11, 2012 I placed order # 114997 with Norwall PowerSystems for a Generac 17kw residential generator and transfer switch. I paid them $3620,12 for the unit. The serial number on this unit is#7046623.

I received the unit from UPS Freight on August 22, 2012. I had a slab poured and a propane tank installed and then had the generator installed on September 21, 2012.

The unit started and stopped and could not be restarted to test it. Mr Seth Wilson (Suke Enterprises) is a licensed Generac technician. His report was that the magneto had fragmented sending debris all over the inside of the casing.

He suggested that I needed to call the `resolutions' department at Generac and see what they would do. On 10/8/12, I talked to Angi Miller, a `resolution specialist' and she referred the claim to a (?technical disputes person) who was to evaluate the report from Mr Wilson. I requested that they send me a new unit. Ms Miller, called and emailed me back that the warranty only guaranteed that they would fix the unit, and that they would send the parts to Mr Wilson who would then come and fix the unit. Although I did not want a repaired broken unit and wanted the new unit I had payed for, she said that I had no other option.

I met Mr. Wilson at the site on 10/25/12 @ 10am. He worked until 5pm. He disassembled the entire unit (see photos) in order to replace the flywheel and the ignition coils on my brand new never used Generac 17KW unit.

The disassembled unit is now a bunch of parts in a pile. Mr. Wilson finally determined that the crankshaft was bent and he would be unable to fix the unit. There was no reason to reassemble the unit so he left it in over 50 pieces.

On 10/26/12, Mr.

For 12 years I had a portable honda generator that did not fail. But my husband has a heart condition and I wanted something that automately turned on and so we spent over 10,000 between the Generac generator, the electrican and the city permits and after three days, this brand new generator failed to restart after we shut it down to cool down, had the electrician service it with oil and with 55 percent of the propane remaining in the tank. It turns out we need a new panel or something and have to wait for it to be delievered from Michigan to Ct. For a BRAND NEW product. And by the way try and reach the company. Good luck with that. It turns out several of my colleagues had the same experience. How many others had this expereince? I say it is time for a class action. I came to work this morning sat november 3 because cannot stay in the cold dark house with spoiling food and smelling bathrooms any longer.
