Rehlko Reviews 

Between myself and a few friends we have spent over $100k on 4 new 26RCAL generators and cannot get the projects completed and cannot get any response and/or communication from Kohler/Rehlko!!!!! They actually told our dealer to stop giving us their number!! What kind of customer service is this. I love the old Kohler generator but I am FURIOUS DEALING WITH THE TOTAL LACK IF COMMUNICATION AND CUSTOMER CONCERN FROM REHLKO. I WOULD NEVER RECOMMEND
THEM TO ANYONE WITH THIS TYPE OF CUSTOMER SERVICE!!!!!

As a dealer who expects a baseline of professional partnership, I am deeply disappointed by the completely unacceptable customer service from Rehlko (formerly Kohler).We paid $1,000.00 for employee training and needed to reschedule the session. Instead of accommodating a working partner, Rehlko is outright refusing to honor our original payment and is demanding an additional $1,000.00 to rebook.To make matters worse, their communication is non-existent. I spent an entire workday trying to resolve this issue. I sent more than six emails across Friday and yesterday, most of which went completely ignored. When I finally received a single response nearly six hours later, it contained zero helpful information and didn't even include the employee’s name or contact details.For a company that prides itself on being a reputable brand, treating authorized dealers with this level of disregard and pulling predatory pricing tactics is shameful. We expect much better support and accountability from our partners.

BAD GENERATOR JUJU
PERSONALIZED POWER SYSTEMS
RETAILER AND INSTALLER
PAID TOP DOLLAR... THEY TALKED ME INTO A KOHLER.
BAD MISTAKE. THE COMPANY WAS CHANGING OWNERSHIP.
THEY INSTALLED THE THING. NEVER WORKED FOR THE FIRST ALMOST 8 MONTHS!!! RETAILER SENT ME BACK TO THE MANUFACTURER. MANUFACTURER TOOK NO RESPONSIBILITY TO RESTORE MY 8 MONTHS OF WARRANTY. IT WAS THE RETAILER THAT SENT INADEQUATE HELP THAT DID NOT DIAGNOSE THE PROBLEM. AFTER ME PURCHASING A PART AND PAYING THEIR TECH TO PUT IT IN, THEY SENT SOMEONE ELSE THAT DID NOT KNOW ANYTHING. AND THEN...A GLIMMER OF A BRAIN. THIE NEW TECH RICK DICOVERED THE PROBLEM! I KEPT COMPAINING WHY DO I HAVE TO GET ANY NEW PARTS, IT IS A BRAND NEW MACHINE???? HOW DO I GET MY WARRANTY FOR THE 8 MONTHS BACK. WHY DID A NEW GENERATOR NEED NEW PARTS? NO ONE REMAINS FROM THE OLD COMPANY! THEY ARE BLAMING THE OTHER TECHNICIANS, THE MANUFACTURER, THE OLD OWNER, THE NEW OWNER???? I DON;T KNOW HOW TO GET MY 8 MONTHS OF WARRANTY BACK. AND ALL OF THE HOUIRS ON THE PHONE WAITING FOR SOMEONE THAT NEVER PICKED UP TO RESPOND. PLEASE DON'T BUY FROM THESE HORRIBLE PEOPLE WHO CARE NOTHING ABOUT THEIR CLIENTS!!! AND KOHLEER OR REHLKO DID NOT OFFER ANY ASSISTANCE OR ANY MONTHS BACK ON THEIR WARRANTY. I GUESS THEY DON'T THINK MUCH OF THEIR PRODUCT!!!

Uses the same time stamp for every event. Consequently, if I'm out of town I have no idea how long my generator was running.

I purchased a Kohler (now Relhko since 2024-09-17) 12 kW residential standby generator in March 2021 that went online in May 2021. Before that generator, at a different residence, I owned a 16 kW Generac generator for 12.5 years.

I was initially going to leave a one-star review, but to be fair to Rehlko, my 2021 Kohler 336HGMHR0166 model 12RESV generator has been much better overall than its Generac predecessor. My current issues with the Rehlko generator are a faulty low oil pressure sensor, which was finally diagnosed by my installer late last week. That is to be replaced at a future date.

Most importantly, the Android version of the Kohler Home Energy app is no longer displaying the total electrical load on my generator. That is critical information for me, since my 12 kW Rehlko generator cannot meet the electrical load in winter of this electrically-heated two-story old home. I need to avoid an overload situation by switching off electrical load that I deem non-essential.

The online app (now discontinued) and the mobile app formerly displayed that information. Now the mobile app does not, and I am flying blind.

My efforts to have Rehlko Support respond to my concerns have met with a bunch of "boilerplate" responses. They suggested that they would send my request to their developers to add this "new" feature.

It is not a "NEW" feature: it did work, and now it doesn't! I have sent Rehlko screenshots of the app on my phone showing that it did display that information. Since then I have been ignored.

I have repeatedly requested via email that Rehlko Support escalate my complaint to the appropriate Director, requesting his/her acknowledgement. All I have heard is silence.

As such, I am being "generous" by leaving a three-star review. The generator itself is well-designed, and it is far superior to the former Generac that I owned. Parts do fail, but there is no excuse for deficient support. Neither Kohler, nor Rehlko, give away these generators. They are very expensive to purchase and install.

I WILL update this review and perhaps change my rating, if I ever hear again from Rehlko Support and the appropriate Director. In the meantime, potential and existing customers should be aware that the support is not as good as it was when it was under the Kohler brand name. I know, because Kohler Support was very attentive to a previous 2021 complaint and help me resolve my issues.
