A car that won't start doesn't always mean the battery is flat. In fact, many breakdowns we attend across the UK turn out to be simple issues that are often misdiagnosed or misunderstood.
At Avant Auto Assist, we provide nationwide roadside assistance across the UK, including fast-response breakdown support in Preston, Manchester, Liverpool, Blackburn, and the wider North West.
This is a real call-out example from Preston where the issue looked serious—but turned out to be something much simpler.
"My Car Won't Start After Parking Up"
We were contacted by a customer in Preston who explained the following:
- They were driving normally
- Parked the vehicle and switched it off
- When they tried to restart it, the car would not start
The customer was understandably concerned and unsure whether they needed a jump start or a recovery.
We confirmed the details over the phone and arranged attendance immediately.
We were already finishing a job nearby, so we provided a 15-minute ETA and arrived on time.
On-Site Diagnosis: Not What It First Looked Like
When we arrived, the assumption was that the vehicle had a flat battery.
However, we always carry out proper diagnostics before starting or replacing anything.
We tested the battery and found:
The battery was reading 12.6 volts
This told us something important immediately:
- The battery was healthy
- A jump start was not required
- The issue was likely elsewhere in the starting circuit
The Real Problem: Loose Battery Terminals
After further inspection, we found the actual cause:
The battery terminals were loose
This meant:
- Power was not being properly transferred to the vehicle
- The car could not complete the starting process
- It appeared like a flat battery, even though it wasn't
This is a very common issue we see on roadside call-outs.
Once the terminals were secured, the vehicle started immediately.
Secondary Issue: Rear Windows Not Working
The customer also mentioned another concern:
Rear windows were not working
They believed this indicated a battery or electrical failure
After checking, we identified the real cause:
The child lock for the rear windows was activated
This meant:
- Rear window controls were intentionally disabled
- There was no electrical fault
- No battery or wiring issue was present
We explained how the system worked and showed the customer how to operate it correctly.
What We Did on Site
On this Preston call-out, we:
- Carried out full battery diagnostic testing
- Confirmed battery was healthy (12.6V)
- Identified and secured loose battery terminals
- Explained rear window child lock system
- Tested vehicle starting system
- Ensured everything was working correctly before leaving
No unnecessary parts were replaced, and no jump start was needed.
Why Fast Response Matters
The customer told us they had already:
- Been given a 2+ hour ETA by other recovery companies
- Had one company cancel on them entirely
Because we were nearby, we arrived within 15 minutes.
This highlights a common issue in breakdown situations:
Speed of response often matters just as much as the repair itself.
Key Lesson From This Breakdown
Not every non-starting vehicle is caused by a dead battery.
In this case, the real issue was:
- Loose terminals preventing proper electrical contact
- Misinterpreted symptoms caused confusion
This is why proper roadside diagnostics are essential before replacing parts or calling for recovery.
Common Signs of Loose Battery Terminals
If your terminals are loose, you may notice:
- Car won't start intermittently
- Clicking sound when turning the key
- Electrical systems behaving inconsistently
- Dashboard lights flickering or dimming
This can easily be mistaken for a flat battery.

Frequently Asked Questions
Why won't my car start if the battery is showing voltage?
Even with good voltage, loose or corroded terminals can prevent power from reaching the vehicle.
Can loose battery terminals stop a car from starting?
Yes. They can completely interrupt power flow and make the vehicle appear dead.
Do I need a jump start if my battery is 12.6V?
Not usually. 12.6V indicates a healthy battery—diagnosis should focus elsewhere.
Why are my electric windows not working?
It could be a simple feature like child lock activation, not an electrical fault.

In this case, we arrived within 15 minutes as we were already nearby. Response times vary depending on location.
