Car repairs are a part of life. Sometimes, you want to upgrade your ride or fix a problem fast. But not every repair is a good idea—at least, not if you want your car insurance to stay valid. Many drivers don’t realize that some changes, even when done by a professional, can void their insurance policy. This can leave you paying out of pocket after an accident or claim. Knowing which repairs are risky can save you money and stress. Here are ten car repairs that can invalidate your insurance, even if a shop does the work.
1. Engine Swaps
Swapping your car’s engine for a more powerful one sounds exciting. But it’s a big red flag for insurers. Most policies are based on the original engine’s specs. If you install a bigger or different engine, your car’s performance changes. This can make it riskier to drive. If you don’t tell your insurer, your policy may become void. Always check with your insurance company before making this change.
2. Suspension Modifications
Lowering or raising your car’s suspension can alter its handling. Some people do this for looks, others for off-roading. But these changes can affect your car’s safety and stability. Insurance companies often see modified suspensions as a higher risk. If you get into an accident, they might refuse your claim. Even if a shop does the work, you need to report it to your insurer.
3. Non-Standard Wheels and Tires
Upgrading to larger wheels or low-profile tires can make your car look sharp. But these changes can also affect speed readings, braking, and handling. If the manufacturer doesn’t approve your new wheels or tires, your insurance could be at risk. Some policies only cover standard equipment. Always check your policy before making this change.
4. Performance Chip Tuning
Performance chips or ECU remaps can boost your car’s horsepower. But they also put more strain on the engine and other parts. Insurers often see this as a sign you’ll drive faster or more aggressively. If you don’t declare this modification, your insurance may not cover you after a crash. Even if a professional tunes your car, you need to tell your insurer.
5. Aftermarket Exhaust Systems
A new exhaust can improve your car’s sound and even add power. But aftermarket exhausts can also make your car louder than legal limits. Some systems may not meet emissions standards. If your car doesn’t pass inspection or breaks noise laws, your insurance could be void. Always check local laws and your policy before installing a new exhaust.
6. Window Tinting Beyond Legal Limits
Dark window tints can look cool and keep your car cooler. But every state has laws about how dark your windows can be. If your tint is too dark, your car may be illegal to drive. Insurance companies can refuse claims if your car doesn’t meet legal standards. Even if a shop installs the tint, you’re responsible for making sure it’s legal.
7. Roll Cages and Racing Seats
Adding a roll cage or racing seats can make your car safer on the track. But on the street, these changes can be a problem. Some insurers see roll cages as a sign that you plan to race your car. Racing seats may not have the same safety features as factory seats. If you don’t declare these changes, your insurance could be invalid.
8. Non-Factory Lighting
LEDs, underglow kits, or extra-bright headlights are popular upgrades. But non-factory lighting can be illegal or unsafe. Some lights can blind other drivers or distract you. If your car’s lighting doesn’t meet legal standards, your insurance may not cover you after an accident. Always check the law before adding new lights.
9. DIY Bodywork and Paint Jobs
A fresh paint job or custom body kit can make your car stand out. But if the work isn’t up to standard, it can affect your car’s safety. Poorly fitted panels or bumpers can make accidents worse. Some insurers won’t cover cars with non-standard bodywork, even if a shop does the work. Always check your policy before making big changes to your car’s body.
10. Brake System Upgrades
Upgrading your brakes can seem like a smart move. But if you use non-approved parts or change the system’s design, you could be in trouble. Some aftermarket brakes may not meet safety standards. If your brakes fail and cause an accident, your insurer may refuse to pay. Always use approved parts and tell your insurer about any changes.
Protect Your Coverage by Staying Informed
Car repairs and upgrades can be tempting, but they come with risks. Insurance companies base their policies on your car’s original specs. Any change, even if done by a professional, can affect your coverage. Always read your policy and talk to your insurer before making repairs or upgrades. It’s better to be safe than sorry. If you’re not sure, ask your insurance company for advice. Protecting your coverage is just as important as protecting your car.
