UK drivers are being cautioned that a common cold-weather habit could set them up for a four-figure repair bill in the future. Ignoring a basic engine warm-up procedure during winter months may lead to significant transmission damage, with fix costs exceeding £2,000 for some vehicles.
The Costly Cold-Start Habit
According to motoring content creator Pete, known online as @capturing_cars, the risky routine involves starting a cold car and driving off immediately. "Did you know that jumping into your car, starting it up cold, and simply driving straight off can be seriously damaging to your vehicle long term?" he stated in a warning issued in late December 2025.
Pete emphasises that the potential harm isn't instant but accumulates over time. The core issue is cold friction within the gearbox, which is exacerbated when the transmission fluid hasn't had time to warm up and circulate properly. This unnecessary strain gradually wears down internal components.
Your Car's Built-In Warning Signal
The expert explains that vehicles provide a clear, universal indicator for when they are ready to drive. The method applies to both older and modern cars.
"All you need to do is start up your car for the first time in the morning, and you'll see that the revs are sitting just over a thousand RPM," Pete advises. "It will stay there for a little while. After a while, people will notice that the revs will eventually drop to just below 1,000 RPM."
This drop in engine revolutions per minute is the car's signal that it has reached a sufficient operating temperature. "That's the car's way of giving you a good indicator as to when it's warm enough that you can put the car in gear, drive it, change gear, etcetera," he added.
The Financial Impact of Skipping Warm-Up
Neglecting this simple step can have severe financial consequences. The primary risk is damage to the gearbox, one of the most complex and expensive parts of a vehicle to repair or replace.
A full gearbox replacement typically costs between £500 and £2,800, with the final price heavily dependent on the car's make and model. For many drivers, this means a bill potentially surpassing two thousand pounds, all stemming from a preventable daily habit.
Pete recommends a practical approach: "I tend to wait in my car for a couple of minutes, which is longer than overly required." A short wait, guided by the rev counter, allows fluids to thin and lubricate critical components fully, protecting the transmission from premature wear and tear.
This winter driving tip serves as a reminder that minor preventative measures can avoid major mechanical failures and save drivers from unexpected and costly garage visits.
