Tire Compressor broken again

Hello Minor problem compared to others but I wonder how long these compressors/Seal kit last. I had to replace one with the 2013 volt and now the one with my 2015 Volt broke. At the switch. I was expecting this one with the 2015 to go as it was laboring alot after 35PSIG where the units with the 2013 hummed right along to 42 PSIG. Actually the unit reads about 45PSIG to get 42 PSIG on the tires. You have to overshoot what pressure you want to see on the display. I think I checked this a few years ago with a hand gage and the display is more accurate then the compressor gage.
