Does a slightly cracked rear bumper need to be replaced?
2 Answers
If the rear bumper is slightly cracked, it needs to be replaced. Here are the relevant details: Reason: If the internal bracket of the bumper is severely damaged or cracked, it generally requires replacement. When replacing the bumper, it is best to choose an original equipment manufacturer (OEM) part. Although the price is relatively higher, OEM bumpers are of better quality than aftermarket ones, offering superior toughness. Even under high pressure, they are less likely to deform, and there is minimal color difference. If conditions permit, choosing an OEM bumper is the best option. Rear Bumper: The rear bumper is a crossbeam located below the taillights. In addition to maintaining their original protective function, front and rear bumpers are designed to harmonize with the vehicle's styling and achieve lightweight construction. Nowadays, most car bumpers are made of polypropylene plastic.
In cases where the rear bumper is only slightly cracked, my opinion is that immediate replacement isn't always necessary. It depends on the extent of the damage: if the crack is very small, measuring just a few centimeters in length and not distorting other components, it can usually be professionally repaired using methods like plastic welding or patch filling, followed by repainting. This approach can save a significant amount of money. The primary functions of a bumper are collision protection and impact absorption, and minor damage typically doesn't compromise these safety features. However, if the crack extends into structural support areas or causes sensor malfunctions, replacement becomes necessary. Additionally, bumpers on newer or high-end vehicle models may contain internal airbags, and even micro-cracks can affect waterproofing and sound insulation. It's advisable to have a professional inspection at an auto repair shop to prevent potential hazards. Maintaining bumper integrity is important for daily driving, so I recommend checking for damage during routine maintenance.
