Where did the legendary phrase come from and why did it become a meme?

Have you ever heard from a mechanic at a car service: “This has never happened before and here it is again!”? This phrase has long become an internal meme among motorists and mechanics. It is pronounced in cases where the car presents a surprise - a breakdown that the master saw for the first time... or for the hundredth time in a week. Paradox?

In fact, behind this joke lies a whole layer of professional experience. Auto mechanics face non-standard faults daily: then Toyota Corolla 2010 will give an error that is not described in any manual, then Volkswagen Passat will start to “glitch” after changing the oil. It is at such moments that this phrase sounds - as a sign that even experienced specialists have situations when they have to improvise.

But why “and here we go again”? Here lies the second meaning: some breakdowns that seem unique are actually repeated with alarming regularity. For example, crankshaft position sensor failure Renault Duster after washing the engine or valve sticking EGR on diesel Skoda Octavia - the master sees such cases over and over again, but each time they surprise with their “unexpectedness”.

When masters say this phrase: top 5 situations

Not every breakdown deserves a legendary comment. There are specific cases when even experienced mechanics clutch their heads. Here are the most common of them:

  • 🔧 "Self-diagnosis" of electronics: The machine shows an error that does not exist in the database. For example, Ford Focus gives a code P25A2 - but there is no such thing in the manual.
  • 🛢️ "Oil" in unexpected places: antifreeze in the gearbox, brake fluid in the washer reservoir or diesel fuel in the cooling system. Classic of the genre!
  • 🔥 “Spontaneous combustion” of wiring: no short circuit, no overload - just like that, “from a good life.” Often found on Lada Vesta first issues.
  • 🚗 "Invisible" knocks: the owner complains about a knock in the suspension, but upon diagnosis everything is fine. And a week later the knocking appears again - and disappears again.
  • 💻 "Updates that break the machine": firmware of the engine control unit (ECU) from an official dealer - and the car stops starting.

It is interesting that some of these situations are so typical for certain models that experts already know how to “treat” them. But every time such a breakdown happens, the same phrase is heard - as a tribute to tradition.

What to do if the master told you this phrase?

If you heard from a mechanic “This has never happened before and here it is again”, this is not a reason to panic. But you shouldn’t relax either. Here is the algorithm of actions:

  1. Check details: ask the technician to explain what exactly is “unique” about the breakdown. This may be a common problem with your model that you weren't aware of.
  2. Check your repair history: if the car was at another service station, compare the diagnoses. Sometimes a “unique” breakdown is a consequence of previous unprofessional repairs.
  3. Request photos/videos: Let the technician film the problem node on camera. This will help when contacting another specialist or warranty center.
  4. Ask about the warranty: if the repair is non-standard, check whether the service station provides a guarantee on the work. Some workshops refuse warranty in such cases.

It is important to understand: the phrase can mean either a truly rare case or an attempt by a master inflate the cost of repairs under the pretext of "complexity". If the explanations sound vague and the price seems too high, this is a reason to seek a second opinion.

Car models that most often “surprise” masters

Some cars are notorious for regularly stumping mechanics. Here are the top 5 “unpredictable” models according to car services:

Model Typical "unexpected" breakdown Frequency of cases (according to surveys of masters)
Renault Duster (until 2018) Oil pressure sensor failure after filter replacement 1 time for 20-30 cars
Volkswagen Tiguan (2010-2015) Spontaneous turbine shutdown without errors 1 time per 50 cars
Lada Vesta (2015-2017) Short circuit in the fuse box for no apparent reason 1 time for 15-20 cars
Ford Kuga (2013-2019) Antifreeze leakage through microcracks in the cylinder block 1 time per 40 cars
Nissan Qashqai (2014-2020) CVT failure after oil change (even with original oil) 1 time per 30 cars

If you own one of these models, you should study the “weak points” in advance and be prepared for the master to tell you the famous phrase. By the way, Renault Duster and Lada Vesta There is a whole series of “proprietary” breakdowns that have already become the talk of the town in services.

Why Lada Vesta so often “surprises” masters?

First games Vesta suffered from wiring problems due to skimping on wire insulation. In addition, the fuse box had design flaws that led to short circuits for no apparent reason. Many mechanics still recall cases when a car refused to start due to oxidation of contacts in the most unexpected place - for example, in the connector of the coolant temperature sensor.

How to avoid “unexpected” breakdowns: prevention

Of course, it is impossible to completely insure against surprises, but you can significantly reduce their likelihood. Here's what experienced mechanics recommend:

  • 📅 Follow the maintenance regulations - even if the car “drives like a nova”. For example, changing the oil in DSG every 60 thousand km prevents 90% of problems with the gearbox.
  • 🔍 Check your car before long trips: Pay attention to the condition of belts, hoses and electrical connectors. Especially relevant for Volkswagen and Skoda with their love for “spontaneous” leaks.
  • 🚿 Avoid engine washing - unless it is a specialized service. Water getting on sensors or connectors often leads to “unexplained” electronic glitches.
  • 🔌 Don't ignore small mistakes: even if the car drives normally, the code P0420 (low catalyst efficiency) can lead to serious problems later.

Pay special attention firmware. Many “unexpected” breakdowns occur after updating the control unit software. If your Ford or Mazda requires updating - check with your dealer to see if there have been any complaints about this firmware version.

💡

Before visiting the service center, record on a voice recorder all the “oddities” in the car’s behavior over the past weeks: when the knock appears, at what speed the engine jerks, how often the check light comes on. This will help the specialist make a diagnosis faster and avoid unnecessary expenses for diagnostics.

When is “this has never happened” a bad sign?

In most cases, the phrase does not pose a threat, but there are situations when it should alert you:

⚠️ Attention: if the master says this up to diagnosis, not after - perhaps he is trying to hide his lack of experience with your model. In this case, it is better to clarify how many similar machines he has already repaired.

Another alarm bell is if the phrase is accompanied by:

  • Refusal of a written estimate (“we don’t know what we’ll find there”).
  • Requiring prepayment for “complex” repairs.
  • Assurances that “no master can do a better job.”

In such cases, it is worth looking for another service. An honest master, even when faced with a non-standard breakdown, will offer:

  1. Carry out step-by-step diagnostics, recording each step.
  2. Connect with colleagues or explore technical forums (eg. Drive2 or Autodata).
  3. Offer alternative repair options with a risk assessment.
💡

If the master says “this has never happened before”, but at the same time confidently names the cause of the breakdown and how to eliminate it - this is a good sign. It’s worse when the phrase sounds like an excuse for ignorance or unwillingness to delve into the problem.

FAQ: We answer frequently asked questions

Is it possible to diagnose an “unexpected” breakdown yourself?

Theoretically yes, if you have a scanner (eg ELM327) and access to error databases (Autodata, Mitchell1). However, many “unique” breakdowns require experience. For example, a knock in the suspension can be caused by either a worn bushing or a crack in the subframe - and this is a safety issue.

If you are not sure, it is better to contact a specialist. But before visiting the service, you can check yourself:

  • Level and condition of technical fluids.
  • Presence of errors via scanner or on-board computer.
  • Visual inspection for leaks, broken wires, damaged hoses.
Why is the same breakdown called “unique”?

The fact is that even typical faults can manifest themselves in different ways. For example, mass air flow sensor failure (MAF) on Toyota Camry usually causes floating rpm. But sometimes it leads to the fact that the car stalls only when the air conditioner is turned on - and such a symptom may surprise the mechanic.

In addition, the same breakdown on different machines can have different causes. For example, crankshaft oil seal leak on Renault Megane is often associated with a design defect, and Kia Rio - with incorrect installation of the timing belt.

How to politely ask the master to explain what he means?

It is better to avoid statements like “What are you talking about?” or “Explain normally”. Instead you can say:

“Sorry, I don’t quite understand. Could you tell us in more detail what exactly the problem is? Maybe you can show me on a diagram or photograph?”

If the master refuses to explain, this is a reason to doubt his qualifications. A good specialist is always ready to clearly tell the client about the essence of the breakdown.

Is it worth agreeing to a repair if the repairman says he doesn’t provide a guarantee?

It depends on the situation. If we are talking about experimental repair (for example, soldering control units instead of replacing), then the lack of warranty is justified. But if the master refuses to give a guarantee for standard work (timing belt replacement, suspension repair), this is a reason to be wary.

In such cases:

  1. Clarify why there is no guarantee (low-quality spare parts, complexity of work, etc.).
  2. Ask for a written refusal stating the reason.
  3. Compare prices and conditions in other services.

Remember: the lack of a guarantee does not always mean fraud, but it’s not worth the risk.

Is it possible to get a refund if the problem remains after repair?

Yes, but for this you need:

  1. Have a written estimate and certificate of completion of work.
  2. Record all conversations with the master (for example, correspondence in instant messengers).
  3. Submit your complaint to the service in writing (indicating the deadline for eliminating the deficiencies).

If the service refuses to return the money, you can:

  • Contact Rospotrebnadzor.
  • Write a complaint on the site ONF or Dobrodel.
  • File a lawsuit (if the amount is significant).

Important: if you signed the work completion certificate without any comments, it will be more difficult to return the money. Always check the car before paying!
