2022 Ford Maverick Hybrid No Crank No Start? A Common TSB Fix That Gets You Back on the Road
How a loose high-voltage battery cable connection can leave your Maverick silent — and why proper diagnosis matters more than ever on hybrid trucks.
We’ve all been there: You go to start your truck in the morning and… nothing. No crank, no dash lights, just silence. For owners of certain 2022 Ford Maverick hybrids, this frustrating no-start condition often points to a known issue covered by a Ford Technical Service Bulletin (TSB 22-2340).
At Leon's PROFIX Auto Repair in Norman, OK, we understand how stressful it is when your vehicle won’t start — especially a newer hybrid you rely on every day. The good news? With the right diagnostics and the correct repair, it’s very fixable.

Diagnosing the No-Crank Condition
Recently, a customer brought in their 2022 Ford Maverick XL Hybrid that had developed a complete no-crank, no-start condition. The truck had no 12V power supply in the battery junction box, which is a classic symptom of this service bulletin.
Instead of jumping straight to replacing the 12V battery (a common first guess), our technician performed a thorough diagnostic and inspection following Ford’s guidelines. A wiggle test on the C1617E eyelet terminal — the connection where the high-voltage battery cable assembly meets the system — revealed the problem: a loose and partially detached connection. Over time, this eyelet can work itself free, cutting power and leaving the truck unable to start.
Here’s what the engine bay looks like on this Maverick Hybrid. The high-voltage orange cables are a big clue that this is a hybrid powertrain requiring special care.
Why Proper Diagnosis Makes All the Difference
This is exactly why we emphasize proper diagnostics at Leon's PROFIX Auto Repair. Hybrids have complex high-voltage systems, and simply replacing parts without testing can lead to repeated visits and unnecessary expense. In this case, the service bulletin advised us to replace the complete high-voltage battery cable assembly - along with the required hardware and clips.
The repair involves safely de-energizing the high-voltage system, removing the old wiring, and installing the updated assembly — a job that takes careful attention and several hours of labor. We also inspected related components and noted a broken lock on the battery junction block that occurred on arrival.
The failed eyelet terminal connection that caused the no-crank condition. This small but critical point of failure is what the TSB specifically addresses.

Getting the Maverick Back on the Road
After the repair, the Maverick fired right up and has been running reliably since. Following the manufacturer’s technical service bulletin ensures we’re fixing the root cause instead of just treating symptoms.
If your 2022 Ford Maverick Hybrid is showing no-crank or no-start symptoms, don’t assume it’s just a dead battery. A diagnostic check and inspection can identify whether the high-voltage cable eyelet connection is the culprit. Addressing it promptly with the proper repair can save you time, money, and headaches down the road.
