The Most Expensive Mistakes in Car Manufacturing

When a car manufacturer gets something wrong-whether a serious safety issue or a product that just doesn’t sell-they can lose billions. We’re talking about recalls that cover millions of cars and flop models that damage a brand’s reputation. These mistakes affect everyday drivers like us in Manchester and Stockport, because the used-car market picks up the aftermath. At Dace Motor Company we see how those legacy errors ripple through.

Let’s break it down into two main types of mistakes: safety/design recalls, and commercial/design flops. Ready? Let’s go.

Major Recalls That Cost Big

General Motors ignition-switch debacle

This one is a classic. GM had a fault in the ignition switch on certain models that could shut off the engine while driving, which meant airbags didn’t deploy when they should. Over time the company ended up recalling around 30 million vehicles worldwide. They also paid large fines and compensation. 

What went wrong? The switch failed under vibration or the key-ring load. GM knew about the issue years before acting. 

What’s the lesson for you at Dace Motor Company? When we inspect used cars (and we always do), we check for recall history. Buying a car that’s been part of a big recall isn’t a deal-breaker, but you want to know it’s been properly fixed.

Toyota Motor Corporation – unintended acceleration / floor-mat issue

Toyota is known for reliability. But in 2009-10 they had to recall over 9 million vehicles worldwide because some cars accelerated unintentionally-initially blamed on trapped floor mats, later gas pedal issues. They ended up in a settlement for about US$1.2 billion for concealing the defects. What’s the takeaway? Even the brands you trust can slip. At Dace, when we bring in used cars from manufacturers like Toyota (we do stock them!), we check that any recall work is up to date.

Takata Corporation air-bag inflator crisis

One of the widest and costliest recalls ever: airbags from Takata could explode and send shrapnel into the cabin. Hundreds of injuries, dozens of deaths. The number of affected vehicles? Easily tens of millions globally.

Why this matters for you in the used-car market: If you’re looking at a used car of a certain age or type and it had Takata-supplied airbags, you want to check whether the recall fix was done. At Dace Motor Company we ensure full HPI checks are done, and we ask for service records-so you’re not left wondering.

Volkswagen AG “Dieselgate” – emissions scandal

Although this is less about a physical safety defect, this is a big mistake in manufacturing/manipulation. VW admitted to cheating diesel emissions tests, affecting millions of vehicles (≈11 million) globally. The fallout: huge fines, recalls, reputational damage.

Used-car buyers often don’t want to pick up cars with a shadow hanging over them. At Dace Motor Company we check the history so you don’t buy trouble.

Design or Commercial Flops That Cost Millions

Sometimes the mistake isn’t safety-it’s just that a car fails to hit the right note. Here are some big ones.

Ford Edsel

If you’re buying used, the lesson is: a car might be from a reputable brand, but you need to know if it was a successful model or a troubled one.

Renault Avantime

Renault tried something bold: a coupe/MPV mix based on their Espace MPV platform, for just four people. It sold only ~8,500 units. Why? Concept not matching market. People wanted practicality rather than odd packaging.

When browsing used cars, oddbody styles can mean smaller demand, harder to sell later, fewer parts-it matters.

Lincoln Blackwood

This one walked into a niche nobody really wanted: a luxury pickup truck with a trunk instead of a proper load bed. Sales tanked fast. 

So for used car buyers: rarity might seem cool, but when parts or servicing are hard to get, the cost goes up. At Dace Motor Company we prefer cars with good support and known histories.

Why do these mistakes happen?

Here in the North West-Stockport, Manchester-you and I know that “good value” matters. At Dace Motor Company, we check our pricing daily and make sure you’re getting something solid. The manufacturers’ mistakes often come down to a few recurring themes:

• They underestimated the market shift (e.g., Edsel, Avantime).
• They compromised on engineering or safety to save cost (GM ignition switch).
• They mis-judged consumer expectations (Lincoln Blackwood).
• They tried to innovate but skipped steps in testing or quality control (Takata air bags).

These things add up. A recall means thousands to millions of cars, plus reputation damage. A flop means unsold inventory, wasted development budget, and lost trust.

What should you watch out for when buying used?

Since we’re in Stockport and Manchester, and you might be dropping into one of our Dace Motor Company showrooms (Greg Street, Reddish; Buxton Road; Manchester Road; or Eccles), here are concrete things to ask and check:

• Check recall history: Ask for the VIN, have us run a history check. See if any major recalls were issued for that model.
• Check service records: If the recall or fault was fixed, the service record should show it. If not, ask “why not”.
• Check reputation of the model: Some models may have “black marks” in their history-less reliable, less parts availability.
• Check parts and servicing cost: Luxury or rare cars might look classy, but if parts cost more or are hard to source, your cost of ownership goes up.
• Check fit for your needs: If a car was a commercial flop because it didn’t match what people wanted, its resale value might suffer. You want something that’s recognised and demanded.

At Dace Motor Company we make sure every car goes through a full HPI check (80 data points: previous owners, mileage discrepancies, outstanding finance, write-offs). So you’re buying with your eyes open.

Drawing the line: safety vs commercial faults

It’s helpful to separate the kinds of mistakes:

• Safety/design bugs: These are critical. If a car had a big recall (engine could stall, airbags could explode, fuel tank could rupture) you want assurance the fix was done.
• Commercial/design flops: These are more about value and practicality. Maybe the car looked weird, or the concept was off. You may still buy one, but you’ll want to know resale may be weak and servicing might be tougher.

When we stock used cars at Dace Motor Company, we’re leaning into the first category being clear – “No-surprise” cars. For flops we’re more cautious: we’ll highlight any odd background and make sure you're comfortable.

A few extra real-world examples

• The Takata air bag recall: One of the widest ever. Tens of millions of cars, from many manufacturers, were affected.
• BMW’s “N54” engine (2007-10): Some cars had a high-pressure fuel pump problem which let the engine cut out. Around 130,000 cars in the U.S. were subject to recall. 
• Firestone & Ford tyre controversy (1990s): The tyres on certain Ford SUVs (Explorer) had high failure rates, leading to dozens of deaths and major cost.

Each of those show one thing in common: the mistake may start small (a part that fails more than expected), but when multiplied across many units it becomes huge.

What this means for us in Stockport & Manchester

We’re based in this area, you’ll drop into one of our Dace Motor Company showrooms, and you’re looking for a used car that doesn’t come with hidden baggage. Because if you buy a car with sketchy history, the “cheap” upfront cost can be swallowed up by repair bills, downtime, or falling resale value.

Here’s how we use the lessons:

• We pick cars from manufacturers whose models we trust.
• We check for known recall worms.
• We prioritise cars with good service history and known issues already fixed.
• We back our cars with our own in-house warranty (that’s right – we run it ourselves), so you’re covered if something unexpected shows up.

And because you live locally you benefit: we’re right here in Stockport, so any servicing is nearby, you’re not stranded miles away.

Mistakes in car manufacturing can cost millions or billions. Big recalls shake a brand; flops cost time and reputation. But for someone buying used in Manchester or Stockport, the takeaway is: be wise. Ask the right questions. Buy from someone you trust (that’s us!). Make sure your car has a clean past.

At Dace Motor Company we’ve been running for 25 years (since 1993) around Stockport & Greater Manchester. We’ve seen the aftermath of these big mistakes-and we make sure our stock is clear of any nasty surprises. When you walk into our Greg Street show-room in Reddish, or one of our others, you’re backed by someone who knows what to look for.
