The picture splits along duty. Owners on light and medium work mostly report a machine that does the job for the money. Owners who put an EP on hard continuous work report failures inside the first year, and the failures they report are electrical.
The most detailed independent reports on EP sit in a Forkliftaction forum thread rather than in any published review. In August 2013 a dealer running twenty two Komatsu trucks said he bought EP machines as backups and had to retrofit the control systems on all of them within two months, when they all failed. A June 2013 poster listed fractured steering column brackets, a stripped LPG tank toggle, a crack in the frame under the hydraulic tank and broken hood hinges, on machines that were not working hard.
Now the other side. Those posts are dated 2013 and 2016, and describe EP's older engine powered and lead acid trucks. EP did not build its own lithium batteries until 2017, or launch the EFL302 aimed at replacing engine forklifts until 2020. The firm in that thread is not the firm selling the EFL range today. EP's own case study describes one of the first UK EFL181 units running five years without a breakdown, though that is EP talking about EP.
Straight answer. Nobody has published an independent, large sample reliability study of EP's current lithium range. Anyone who tells you EP is proven is either selling them or guessing, and that includes us. Buy an EP for what is checkable: a low buying price, cheap wear parts and a sealed battery. Do not buy one expecting Toyota service life.
