This is a mercedes benz, in the 90's it had a huge engineering failure
and this is why.

see mercedes once tried to make biodegradable wiring.

it all started when germany passed a law requiring a certain percentage of new cars
to be bio degradable

so that when you junk it those parts will return to the earth.

but they decided instead of biodegradable seat covers or headliners

the part they would replace with a eco alternative is the rubber that covers all of
the electrical wires.

Overtime the wires got exposed to the elements and they degraded.

Causing a ton of short circuits and even worse.

mercedes never issued a recall even though a wireing harness with
no insulation is incredible dangerous

would you drive it?

This Is A Mazda 6

This Is A Yellow Sac Spider

They Have A Love Hate Relationship And This Is Why

See Yellow Sac Spiders Are Attracted To Gasoline Like Hyrdrocarbons

And On 2009-2015 Mazda 6's

There Was A Way For These Spiders Drawn Out By The Scent Of Fuel To

Enter The Fuel System And Spin Their Webs Eventually Clogging Everything Up.

After Crawing Through A Small Auxilary Hose Used For Ventilation

Once They Spin There Webs The Gas Fumes Cant Escape Like They Need To And

Pressure Builds Up In The System.

Mazda Became Aware Of This After Several Owners Had Their Gas Tank

Crack And Leak Fuel Due To A Build Up Of Pressure.

Eventually Releasing A Software Patch That Regulates The Fuel System Pressure

Even If There Was Spiders Living Inside

Not Able To Rid Their Bug Problem Mazda Learned To Co-Exist

Would You Drive One?

This Is Ford

This Is FireStone

Ford And Firestone Had A 100 Year Relationship That Ended Abruptly And This Is Why

See This Happened When People Started Crashing In Fords New Suv The Explorer

Police From These Crash Sceenes Would Report That The Entire Threads Were Seperating

From The Tire Itself.

Ford And Firestone Have Been Working Together Since The Model T.

And Were Both Adamant About Resolving The Issue

Firestone Imediatly Recalled 6.5 Million Wilderness Radial Tires

But Even After The Recall The Crashes Continued

So FireStone Would Come Out Saying The Problem Isnt The Tires But

Rather The Explorer Itself Stating It Was Unsafe And Would Roll Over In A

Crash Regardless Of The Tire

Ford Quickly Denied These Allegations And Abrubtly Ended A 100 Year Relationship.

Would You Drive One?

This Is A Toyota Tacoma

From 1994-2004 First Gen Tacomas Suffered From Frame Rusting

Due To Their Box Frames Trapping Water Inside

Which Forced Toyota To Recall 800,000 Trucks

Then From 2005-2011 Tacomas Suffered From A Worse Rust Problem In The Rear

Leaf Spring That Would Rot Causing Them To Snap And In Some Cases

Puncture The Break Lines And Gas Tank

resulting in them Recall Another 690,000 Tacomas

See The Cheap Steel Being Used To Make The Leaf Springs Rusted Easily

Initially Toyota Offered Steel Clips That Would Go Around The Rotting

Leaf Spring And Hold It Together

But Owners Were Not Happy With This Fix

And Toyota Issued A Total Recall

Would You Drive One?

This Is A G Wagon

Originally Used By The Military And German Farmers

They Were Fairly Slow Trucks, But Nowdays Not So Much

They Come Stocked With A Handmade AMG 621 HP Twin Turbo Engine That Does

0-60 In Under 5 Seconds.

But, Despite 4WD And Modern Day Technoloy To Help Keep Them On The Road

Their Tall Stance And Narrow Wheel Base Make Them A Bit Sketchey

At High Speeds

But Could You Imagine That In Reverse?

In 2016 20 G65 AMG'S Had To Be Recalled

Because They Forgot To Program A Electrical Speed Limiter For The Reverse Gear

Allowing The Car To Reach Speeds Of Over 60MPH In Reverse.

When It Should Be Limited To 15MPH

It Was A Quick Fix That Involved Altering Some Code In The ECU

Would You Drive It?

This Is A RX-7

They Have A Horrible Design Flaw

And This Is Why

See When Engineers Designed The RX-7 They Failed To Put The Fuel Filter

In A Easy To Access Location Such As, I Dunno Under The Hood?

Instead Designers Of The 3RD Gen RX-7 Put The Fuel Filter

In The Back Of The Car Between The Differential, The Sub Frame, And They Sway Bar

Meaning You Have To Disassemble The Rear Suspension And Drop The Entire

Sub Frame To Change Your Fuel Filter.

A Job That Should Be Done Around Every 20 Thousand Miles

Being Such A Huge And Expensive Jobs Many Owners Just Didnt Do It

Wich Led To The Filter Becoming Dirtier And Dirtier

Eventually Working Its Way Into The Engine Causeing A Lack Of Power

And Break Downs

Would You Drive One?

This Is Ford

Between 1988 - 1993 Ford Build 7.9 Million Cars And Trucks

With A Faulty Ignition Switch That Would Overheat And Fail

Due To Its Location Next To The Engine

Causing Your Car To Stall, Losing Control Of Steering And Braking

In Some Cases The Ignition Set Itself On Fire Burning Down The Car

For Was Aware Of The Issue But Instead Of Moving It To A Cooler Location

They Decided To Beef
