⭐ 1 Star Diesel Laptops promises never to leave me stranded. They LIED.
⭐ 1 Star — “You Promised to Never Leave Me Stranded. You Lied.” I run a Mobile Diesel Repair business. I work hard, I pay my bills, and I depend on my equipment — including the diagnostic tool I bought from Diesel Laptops. I purchased this tool specifically because I was promised in writing that access would never be shut off for billing issues or subscription update delays. That promise sold me. And that promise? Was a flat-out lie. Let’s start from the beginning. Diesel Laptops aggressively called and emailed me for years before I finally purchased the tablet. My lead mechanic — a grizzled 35-year veteran who can fix anything diesel and has used every system on the market — asked very specific questions based on his past experiences with Diesel Laptops: 1. Does it read Paccar? Sales rep: “Yes.” ❌ Not true. Their website says it too. Still not true. 2. Can it reset auto transmission shutoffs (in-gear reset)? Sales rep: “Yes.” ❌ Not always true. 3. Will it perform regens on all modern diesel trucks in the U.S.? Sales rep: “Yes.” ❌ False. 4. Will it clear codes? Sales rep: “Yes.” ❌ Sometimes — not always. 5. What’s the yearly subscription cost? Sales rep: “There are no additional charges. If you want next year’s updates, you can purchase them for $XXXX.xx — optional.” 6. Will our access be disabled if we don’t buy the next year's updates? Sales rep: “No, you’ll just miss coverage for brand-new trucks after 2026. But we never disconnect your access for billing.” Yet here I am. Shut down three times. And every time it happened, I was out on the road, on dangerous highways, where diesel mechanics are injured or killed every day. I’m not sitting in a cubicle, kicked back sucking up the A/C. I’m out in traffic, under trucks, in the heat, in the dark, in sleet and snow — doing everything I can to keep America’s fleet running. Cutting off my diagnostic tool without warning isn’t just bad business — it’s a massive safety risk. And that "24/7 tech support" they advertise? Total fiction. I’ve spent hours sitting on the shoulder of a highway, in front of a semi-truck, on hold — waiting for help that never comes. Tech support doesn’t answer in the evenings. Or on weekends. Or even quickly during business hours. Usually, you get an email response days later — if you’re lucky. The last time they shut me down? It was over a bill that was issued only 11 days earlier. Not late. Not even clearly due. Just... boom — access revoked. And here’s the kicker: I only owe ONE more payment. Worse still, they love to pull this move on Friday afternoons, leaving techs like me out of work and stranded until Monday. It’s a pattern. It’s intentional. And it’s cruel. They say, “We’ll never leave a tech stranded.” Well, that’s exactly what they’ve done to me. More than once. Jobs cancelled. Income lost. Dangerous situations made worse. All because Diesel Laptops doesn’t keep its word — and clearly doesn’t care about the real-world consequences of their behavior. And good luck finding other honest reviews. Know why? Because they’ve disabled reviews across the internet. Think about what that says. They don’t want the truth out there. I’ve got the screenshots. The emails. The billing records. The silence. I’ve lived it. And I’ve got all the receipts. Wanna see ’em? I’ll share them. So if you're a mobile diesel mechanic or small shop owner thinking about buying from Diesel Laptops — think again. They’ll leave you stranded, silenced, and scrambling... while pretending it’s your fault. And one more thing — the cherry on top of the Diesel Laptops disaster sundae? The tablet wasn’t even set up when I received it. For the first six months, it wouldn’t connect to anything. We called. We left voicemails. We watched videos. We wasted hours. Nothing worked. Finally, I emailed the owner directly, and suddenly I was escalated to a tech — who discovered the tablet hadn’t even been set up before shipping! He remotely logged in, activated settings, pushed a mountain of updates — and boom, it started functioning for the first time since I bought it. Six. Months. Later. While I paid full price for a paperweight. Hallelujah. Mic dropped. Tools thrown. The internet is listening.
