Customer Guide: What to Do If You Have an Issue With Your Car

Something going wrong with a car rarely happens at a convenient moment, whether you are behind the wheel of your own vehicle or a rental picked up for a short trip. A dead battery, a warning light, or a knock from another driver can turn a relaxed journey into a stressful one within seconds.

The good news is that almost every situation on this list has a clear next step. Staying calm and knowing what to do first makes the rest of the process far easier to manage, whether you are a few minutes from home or much further along your route.

What to Do During a Sudden Breakdown

If the vehicle suddenly stops responding properly, the priority is safety rather than diagnosis. Move off the road if you can do so safely, switch on the hazard lights, and place the warning triangle a safe distance behind the vehicle so other drivers have time to react.

Put on the reflective vest before you step out of the car, even for a quick look under the bonnet, since visibility matters more than it seems on a busy road or in poor light. Once everyone is safely clear of moving traffic, work out what kind of help you actually need.

For a SpeedyCars rental, call the office directly rather than an unfamiliar garage, since the team already has the details of your agreement and can arrange the right support straight away. Our separate guide to roadside assistance in Bulgaria covers what recovery and repair services generally include.

If Your Car Will Not Start

A car that will not start is usually, though not always, a flat battery, particularly if lights or other electronics were left running. With your own vehicle, a jump start or a replacement battery often solves the problem within minutes.

Do not attempt a repair yourself in a rental car without checking first, since this can complicate matters if something else turns out to be at fault. Contact SpeedyCars, describe exactly what happens when you turn the key, and let the team decide on the best next step.

In many cases this means arranging assistance on the spot. In others, particularly if the fault looks electrical rather than a simple flat battery, a replacement vehicle may be the quicker solution while the original car is inspected.

Either way, a quick call means you are back on the road with the least possible delay, rather than guessing at a fix that might not solve the underlying problem.

Dealing With a Flat Tyre

A flat tyre is one of the most common problems drivers encounter, usually caused by worn tread or sharp debris such as glass or stones on the road. It is inconvenient, but rarely serious if you deal with it calmly and in a safe location.

Many rental cars, including ours, carry a spare wheel and the tools needed to change it, though this is a practical convenience rather than a legal requirement in Bulgaria, so it is worth checking what is provided before a long journey. Our guide to winter tyre requirements covers the additional rules that apply between November and March.

If you are unsure how to change the wheel safely, or the spare is missing or already damaged, call SpeedyCars rather than attempting a roadside repair alone, especially on a motorway hard shoulder.

What Dashboard Warning Lights Are Telling You

A dashboard light you do not recognise is unsettling, and with dozens of possible symbols, it is not realistic to expect every driver to know them all. The vehicle handbook, kept in the glovebox, explains what each one means and how urgent it is.

Red warning lights generally call for immediate attention, while amber ones allow you to continue carefully to the nearest safe stop. Either way, do not ignore a warning light simply because the car still seems to drive normally.

If this happens in a SpeedyCars rental, call the office and describe the light and any other symptoms, such as unusual noises or a smell. The team can advise whether it is safe to continue or whether a replacement vehicle makes more sense.

Describing the warning light early gives the team time to arrange a proper inspection before a small issue turns into a much larger repair, even if the fault does not seem urgent at first.

What to Do After an Accident

An accident is more serious than a mechanical fault, and safety comes first. Check that everyone involved is unharmed, and call 112 immediately if there is any injury or the situation is unclear.

Once everyone is safe, document the scene with photographs and exchange details with the other driver. Third party civil liability insurance is mandatory in Bulgaria, so this exchange matters even for a minor collision. If the other driver has no valid cover, our note on the guarantee fund explains how compensation can still be claimed.

Contact SpeedyCars as soon as the immediate situation is under control. Under our rental terms, driving under the influence or leaving the scene without a police report can affect what is covered, so following the correct order of steps genuinely protects you, both financially and in how quickly the whole matter gets resolved.

Why Contacting SpeedyCars Straight Away Helps

In every scenario above, the same principle applies: contacting us early gives our team the chance to guide you, rather than leaving you to work things out alone in an unfamiliar country. Keep your rental documents in the car at all times, alongside your passport and licence.

If you still have questions before your trip, our frequently asked questions page covers many of the situations above in more detail, and our current rental prices page sets out what is included with each class of vehicle.

Whether you collect your vehicle through Sofia Airport Car Rental or from our office in the city, car rental in Bulgaria with SpeedyCars means a direct line to real people whenever something on the road does not go to plan.
