In South Jersey, driving conditions are closely linked to the roadways. Most drivers have experienced what happens to NJ roadways: potholes. Caused by winter’s freeze-thaw cycles and general wear and tear, potholes are one of the biggest dangers to a vehicle, and they are everywhere. Drivers often hit potholes in late winter and early spring. Vehicles with previous damage from accidents may have weakened suspension or steering components that resurface when you hit a pothole.
Pothole season is a “stress test” for any prior repairs after a collision. Here’s what you need to know.
Key Takeaways
- Potholes act as a stress test for vehicles that have previously been in a collision.
- Even minor suspension or structural distortions can worsen after repeated pothole impacts.
- Alignment adjustments alone may mask deeper structural or suspension issues.
- New pulling, vibration, clunking sounds, or ADAS warning lights after hitting a pothole should never be ignored.
- Prompt inspection helps prevent accelerated tire wear, steering instability, and higher repair costs later.
What Happens to a Vehicle When It Hits a Pothole?
Imagine that you’re driving along through South Jersey, maybe on Route 55 or the Black Horse Pike, and you hit a pothole. A large pothole. The tire suddenly drops into the hole. Your vehicle adjusts for this by compression the suspension system to help transfer the force of the impact. Energy transfers through control arms, struts, steering components, and subframe mounting points. All of these can already be damaged after a collision.
A vehicle that has been properly repaired will absorb the shock of a pothole impact correctly. One that has remaining post-collision damage? It can’t absorb an impact.
Types of Hidden Post-Collision Damage That Potholes Expose
Not every collision is going to create damage that gets exposed when you run over a pothole. Let’s take a look at some issues that tend to worsen with repeated pothole impacts.
1. Slightly Bent Suspension Components
After a collision, suspension components can be slightly distorted but also functional. A minute distortion can also be missed during collision repair. Over time, pothole impact worsens the suspension problem. That means that what may have felt fine months ago when you left the collision repair center feels unstable now.
2. Weakened Suspension Mounting Points
Collision shifts parts and components within your vehicle. Even a small fender bender can shift where suspension attaches to the frame. These “mounting points” need to be precisely aligned. Otherwise, other problems start to occur. So when you hit a pothole with unsecure mounting areas, movement happens, and that movement leads to pulling or uneven ride height.
3. Compensated Alignment
Sometimes alignment is merely adjusted to make a car drive straight, but there are micro-shifts that may go unaddressed. In other words, if the structural geometry of the vehicle doesn’t get restored during repairs, the alignment is compensating, not correct. A single strike from a pothole can shift the alignment and put everything out of whack.
4. Pre-Stressed Steering Components
Steering components may sustain damage but still operate after a crash. Those weakened parts can be pushed beyond the breaking point when you hit a pothole. The result is a steering wheel that feels loose or delayed when driving—which can be a huge safety problem.
5. ADAS Sensor Misalignment Becoming Noticeable
Modern vehicles are safer than ever, all thanks to something called Advanced Driver Assistance Systems, or ADAS. Lane departure warnings, rear view cameras, and the like are powered by sensors and cameras that need precise positioning and calibration to function. The downside to these systems is that they are also reliant on the accurate alignment of the suspension system.
If your vehicle’s suspension is misaligned from an accident, your ADAS sensors are also at risk. Repeated pothole impacts can throw off ADAS calibration and notice lane assist drifting, warning lights for no reason, and false collision alerts.
Warning Signs That Potholes Have Exposed Hidden Damage
How do you know if potholes are exposing damages? There are several warning signs that you will visually or physically notice, including:
- Car suddenly pulls after hitting a pothole.
- Steering wheel is no longer centered when driving.
- Vibration when traveling at high speeds on the highway.
- Clunking sounds that weren’t there before.
- Uneven tire wear appearing quickly.
- Vehicle feels “loose” or less stable.
- Dashboard ADAS warning lights.
If the issue begins after hitting a pothole, there is a high chance that the pothole has revealed unaddressed damage. It’s important to get the issue resolved quickly before it worsens further.
Why Previously Repaired Vehicles Are More Vulnerable
Now, here’s one thing vehicle owners need to know: Damage may be repaired, but your vehicle remembers. Unless everything is brand new, damage leaves a mark. Metal that was bent during an accident is structurally changed. Sure, your vehicle may look good as new, yet it won’t resist damage as well as it did the first time. Repaired regions respond differently to stress. Furthermore, if the repairs weren’t fully measured or verified, various points may be slightly off and more susceptible to damage from potholes.
The Long-Term Risks of Ignoring Signs of Post-Collision Damage
Driving around with hidden damage is dangerous. Letting the damage when it become noticeable get worse? That can put you and your passengers at risk. The four main long-term risks include:
- Accelerated tire wear: Misalignment can cause tires to shred quickly.
- Reduced emergency control: Steering instability increases stopping distance.
- Compounding suspension damage: One weakened part will increase stress to others.
- Increased repair costs later: As time passes, what may have been minor can transform into a major replacement down the road.
Frequently Asked Questions About Potholes & Post-Collision Damage
Can a pothole really expose old collision damage?
Yes. A pothole impact can worsen suspension components or mounting points that were previously weakened in an accident.
Why does my car feel different only after winter?
Freeze-thaw cycles create more potholes, and repeated impacts can aggravate existing alignment or suspension issues.
Is a wheel alignment enough after hitting a pothole?
Not always. If structural or suspension components are slightly bent or shifted, alignment alone may only temporarily correct the symptoms.
Can potholes affect ADAS safety systems?
Yes. Advanced Driver Assistance Systems rely on precise vehicle geometry. Suspension misalignment can cause sensor calibration issues or warning lights.
When should I schedule an inspection?
If you notice pulling, vibration, steering changes, unusual noises, or dashboard warnings after hitting a pothole, schedule a professional inspection as soon as possible.
Potholes Don’t Always Create Damage—They Reveal It
Pothole season is coming for South Jersey drivers. Is your vehicle ready for impact? Remember, if you hit a pothole and something feels different, it most likely is. Make sure that your car has been properly inspected after collision repairs to avoid hidden damages from the start. Potholes can cause a lot of issues, but they don’t need to escalate them.
