Do you have childhood memories of a parent in the garage or driveway fixing or maintaining something on the family car? Maybe a family member even taught you a few things. Perhaps you grew up thinking that knowing something about auto body repair was part of being an adult.
And now you are an adult. Maybe you know how to change flat tires or a busted taillight. That’s great! But diagnosing and fixing more significant issues? Maybe that’s beyond your skill set. Well, don’t feel bad; this reflects much less on you than it does the growing complexity of automobiles.
Modern vehicle complexity
What is an automobile? What features define these machines? Tires, an engine, a chassis, a windshield? Well, tires and a body to hold the components together have always been present in cars. If we include “electric motor” as a form of “engine,” then that’s been constant too. And while the earliest models didn’t have windshields, that’s old technology.
And brakes have always been present… but not necessarily the brakes we have today. Regenerative brakes, brake-by-wire technology, and even hydraulic brakes were not always present in automobiles. And automatic emergency braking (AEB) systems weren’t always a part of vehicles. In fact, AEB is an advanced driver assistance system (ADAS), just like lane assist warnings, pedestrian detection, and adaptive cruise control. ADAS rely on sensors, LiDAR, and computer chip components you wouldn’t find in an Oldsmobile Vista Cruiser, let alone a Stutz Bearcat.
Is modern collision repair more complicated?
Modern vehicles have a level of engineering complexity they’ve never had before. Does that mean auto body repair is more complicated today than ever before?
The answer might surprise you … unless you think the answer is “yes,” then you’re right.
Of course, collision repair has increased in complexity since the days when a wrench and a jack could solve most car troubles. Modern vehicles aren’t just mechanical machines anymore, they’re rolling networks of sensors, cameras, radar modules, control units, and software. And these components that enable ADAS and other features have dramatically increased collision repair complexity.
Collision repair today
Let’s look at some specific ways in which auto body repair is more complex today than in eras gone by.
1. Repairs go far beyond the purely structural or cosmetic
A slow-speed fender bender sounds like a straightforward collision repair, right? Except for many modern brands, such a fix may require considering radar units mounted behind plastic covers. That means the auto body repair shop isn’t just replacing and painting a bumper; they’re protecting, scanning, and probably recalibrating safety systems afterward.
2. Calibration requirements
After a collision, even a light one, cameras and radar sensors frequently require static or dynamic calibration using manufacturer-prescribed procedures. This means collision repair technicians need access to specialized scan tools, targets, software subscriptions, controlled environments, and training.
And this isn’t optional. Improper calibration can mean an ADAS misreads distances or doesn’t activate when needed. And the consequences of that could be disastrous.
3. Materials have changed
High-strength steels, aluminum, mixed materials, and complex crumple-zone engineering mean structural fixes require specific auto body repair processes and tools. These include specialized welding techniques, rivet bonding, and manufacturer-recommended repair procedures. Thirty years ago, most technicians could just “pull and fill” to complete collision repair. Today? Not so much.
4. Liability is higher
When an auto body repair affects a safety system, the risk profile heightens. A misaligned radar sensor isn’t just an inconvenience; it’s a liability that increases the potential for future crashes. That increases the importance of documentation, scanning, and procedural discipline.
What does the complexity of auto body repair mean?
So fixing a vehicle is a more complicated process than it was in 1996 or 1926. So what? This article isn’t meant to air the grievances of collision repair technicians who are frustrated by the difficulty of their tasks. In fact, smart auto body repair businesses recognize that this increased complexity also means opportunity.
Shops that invest in training, OEM information access, proper scanning, and calibration capabilities are best positioned to thrive. Drivers who find these forward-thinking collision repair centres will also find the most joy and fewest headaches. Having to wait for a part or a special piece of diagnostic equipment may be aggravating, but it’s far better than going to a substandard shop and receiving a substandard repair. The result of that can be the need for another collision repair because mis-calibrated ADAS sensors caused another collision.
Progress doesn’t stop
Now that auto body repair is less about fixing metal and more about “vehicle systems restoration,” there’s a distinct limitation to what you as a vehicle owner can do. Want to learn how to check your automatic transmission fluid, change your engine oil, and rotate your tires? That’s great; those are all practical skills that could come in handy and save you some money.
But don’t feel bad if you find yourself unable to diagnose and fix certain car or truck problems. Sure, maybe your father or grandfather was handy with a wrench. But how would they recalibrate an ADAS LiDAR system or interface with an onboard computer to diagnose a problem?
With vehicles as complex as they are and the stakes as high as they are, the smartest thing you can do is find reputable professional collision repair technicians you can trust.
