Bests & Worsts Reviews from Amazon

I purchased 2 of the 20RESAL units that were installed in May 2014. They both have the same hunting issues. We added the tubes on the demand regulators to try to solve issues and it did not help. Software was upgraded. Still have the hunting issues. When we take cover off of end where battery is located, generator runs good put cover on and it hunts. Contacted Kohler, they gave phone number for tech 400 miles away, they said we were out of their area. Contacted local service techs listed on Kohler website and when they ask what model the unit is they say that it is a retail model and they do not know anything about them and could not help. Before purchasing unit I contacted Kohler and asked what the difference between RESA and RESAL, they said only difference is the controller, other than that units are identical. When purchasing a new unit you should not be faced with all of these problems. A unit should be running correctly out of the box. Kohler should not be passing these problems on to the consumer. When you purchase a new car you expect to drive it off the lot and go, not take it directly to a garage to make it run correctly. I am very disappointed in the tech service available for Kohler generators and am warning future owners to make sure there is a service tech nearby willing to help resolve issues with unit you intend to purchase. We are still trying to get someone willing to help us and it has been nearly 5 months since units have been installed. Very disappointed in Kohler's service. I am located 80 miles south of Chicago IL.
