Modern Cars Sure Are Reliable, But Are They Durable?

There's nary doubting nan truth that we are surviving successful a aureate property of mechanical competence. Just return a look astatine really nan Japanese cars person taken complete nan reliability mantle. We person reached a constituent wherever cars are little attraction prone and tin spell 10,000 miles betwixt lipid changes. Some moreover travel pinch warranties that screen up to 10 years/100,000 miles. But nan lines are blurred between 2 very different — yet interconnected — concepts: reliability and durability. To put it bluntly, reliability is astir nan present. It's your car's expertise to effortlessly commencement each greeting for nan adjacent 5 years. Meanwhile, durability is nan car's expertise to withstand nan trial of clip for decades.

In galore beingness ways, modern cars are immoderate of nan astir durable cars ever built. Thanks to monolithic advancements successful metallurgy, we person high-strength steels and aluminum alloys that are light, yet incredibly fatigue-resistant. The astir important advancement, though, is rust proofing. In nan 1970s, cars successful nan brackish loop had a support life of astir 3 years earlier their fenders picked up rust. Thanks to modern exertion for illustration galvanized steel, precocious electrocoat primers, and blase cathodic dip coating, your modern car's chassis tin past that brackish loop better. There are still conscionable a fewer models with nan longest imaginable lifespans, but galore modern cars tin survive hundreds of thousands of miles pinch due care.

The problem arises erstwhile this mechanical toughness starts getting undermined by a integer fragility – a problem older cars seldom had to face. Today, almost each portion of a car is connected to a computer. And while that machine adds convenience and absorbing features, it besides adds plentifulness of caller things that tin spell incorrect aliases go outdated.

The bizarre portion is that nan mechanical bits are outlasting nan electronics. Parts for illustration nan block, pistons, and transmission gears are truthful well-engineered that they could theoretically past for  decades. However, nan electronics managing it person a short support life. Fifteen years into nan future, your "perfectly healthy" motor could beryllium a 400-pound paperweight simply because nan Powertrain Control Module (PCM) that manages nan nonstop injection has conked disconnected and is nary longer manufactured. The modern car is also moving from mechanical linkages to drive-by-wire systems wherever each input, for illustration nan throttle and steering, comes from signals generated by a computer. In these cases, a elemental package glitch tin disable an full car.

In a modern car, nan touchscreen infotainment strategy often is nan constituent of interaction to functions for illustration air-conditioning settings, information settings, aliases moreover doorway fastener settings. If nan surface delaminates aliases you're incapable to download mandatory Over-The-Air updates, you're losing a batch much than euphony control. Today, immoderate of nan strongest cars travel pinch physics hardware that, successful nan look of evolving tech, are successful threat of becoming obsolete sooner than expected.

Even worse — if a car's "active safety" sensor fails, nan car mightiness spell into "limp mode," disabling crucial driving aids. A malfunctioning $5 sensor tin efficaciously cripple a $50,000 car. Worse yet, manufacturers tin extremity package support for a car while nan motor is successful its premier moving condition. This leaves owners pinch a perfectly functional motor they tin nary longer usage because nan integer input needed to tally it is now obsolete.

You've astir apt heard of planned obsolescence successful smartphones. The conception seems to beryllium catching up pinch cars, too. Repairing a modern car has transitioned from fixing parts to replacing them. With older cars, you tin rebuild an alternator aliases solder a surgery connection. Today, astir modern car components you spot are designed to beryllium replaced arsenic a whole, not repaired aliases serviced. It's a cascading effect that sets an expiration day connected nan vehicle. When your car is 12 years aged and worthy only $6,000 pinch a azygous $4,300 module failure, it's a full nonaccomplishment scenario. With things going this way, nan financial logic of keeping a car connected nan roadworthy disappears measurement earlier nan car is really worn out. 

The last nail successful nan coffin comes successful nan shape of a deficiency of accessible spare parts successful nan future. As car makers move towards highly-integrated, VIN-locked parts, nan aftermarket ecosystem is incapable to supply cheap, spare alternatives. It moreover makes location repairs excessively costly to beryllium feasible. Cars are destined to nan scrapyard not because they are junkers, but because nan proviso concatenation for their specific, proprietary electronics has ended. Manufacturers mightiness person mastered nan creation of making unbreakable cars, but that's not nan aforesaid arsenic cars that tin beryllium kept live for a agelong time.
