A car is a complex organism that almost never gives up suddenly. Before the metal finally gives up, your car starts to “whisper“ to you about the impending disaster, and if you don't listen carefully, this whisper quickly turns into a deafening financial slap. Recognizing these early symptoms is your only insurance against the nightmare of roadside assistance and cosmic sums at the service station.
There is hardly anything more eloquent than puddles under the car
Even microscopic drops of oil, antifreeze or brake fluid are a red flag that cannot be postponed. These leaks are often just the tip of the iceberg, suggesting burnt seals or punctures, which can lead to fatal overheating of the unit or, in the worst case, to a complete loss of braking power. If the engine starts to "hiccup", the fuel consumption increases unreasonably or a suspicious smoke curtain appears behind you, then it's time to stop postponing diagnostics.
Listen to the sounds
A metallic chatter, a monotonous howl or a shrill whistle are a real cry for help from the transmission, suspension or the engine itself. When strange vibrations are added to the acoustic discomfort, the situation becomes critical. No less alarming are the smells in the cabin. If you smell burnt rubber, something toasted, or that specific sweet smell of antifreeze, know that somewhere under the hood there is a fire or a serious leak that could leave you on the road at the most inopportune moment.
However, safety is most at risk when the car's "gait" changes
A squeaking sound when braking, pulsations in the pedal, or extended braking distance are a direct invitation to an accident. The same goes for the transmission - any "kick" when changing gears or a delayed response, especially with automatics, is a signal for an upcoming expensive repair. If the steering wheel becomes "rubbery" or the car persistently pulls to one side, don't blame the road, but check the suspension and steering system before your iron friend refuses to listen to you for good.
