After a bumper is cracked in a collision, replacement is not always necessary. The appropriate solution can be chosen based on the extent of the damage. Specific standards are as follows: 1. If there are only small cracks after the collision, welding can be used as a remedy. Most repair shops have mature plastic welding techniques for bumpers, and the bumper can still effectively reduce impact force after repair. 2. If the internal support structure of the bumper is damaged after the collision, it is necessary to replace the bumper with a new one. When replacing, it is best to choose an original manufacturer's product to ensure better toughness and quality. 3. If the bumper is severely deformed after the collision, it also needs to be replaced with a new one to better absorb the impact forces encountered during low-speed collisions or scrapes.

From my decade-plus experience in driving, a cracked bumper doesn't always require replacement—it depends on the size and location of the crack. Minor surface cracks that don't affect internal support can often be fixed professionally with plastic welding or adhesive for just a few hundred dollars, ensuring both safety and convenience. However, if the crack exceeds ten centimeters, especially near radar sensors or headlights, repairs may significantly weaken the structure. Daily bumps could worsen the damage, and compromised crash protection poses serious risks. I recall helping a friend inspect his car: a nail-width crack was heat-welded to look brand new, while another at the edge still leaked air and water after repair attempts, ultimately requiring a $2,000 replacement. Safety should always come first—drive to a repair shop immediately for professional assessment. Technicians can accurately determine whether to repair or replace, preventing escalating costs from delayed action. Never gamble with safety; every detail matters when driving.

As the household budget keeper, I always think about how to save on expenses. If the bumper is cracked, there's no need to rush to replace it—repairing is much cheaper than replacing. Small cracks, like the width of chopsticks, can be fixed with hot melt adhesive or welding techniques, saving you hundreds without a problem. However, if the crack is too large, especially near critical areas like sensors, repairs might not hold up, wasting both time and money. I've experienced this firsthand: a small crack on the rear bumper cost me 150 to bond, and it's held up fine till now; another time, the front bumper cracked under the license plate, and after repair, it split open again the next month, forcing me to spend more on a replacement. So, weigh the financials—first check the depth of the crack. Minor cracks can be ignored or simply patched, while deep cracks warrant immediate replacement. Ask a repair shop for a quote; in most cases, minor repairs are sufficient. Saving money is the priority—no need to waste cash for appearances. Safety-wise, minor cracks on a daily commuter car aren't a big deal, but it's best to get them properly fixed before long trips.

As a young car owner who cares about style, a cracked bumper is an eyesore! The damage ruins the overall aesthetic—like a hole in your clothes—so I’d definitely want to replace it or at least clean it up. But realistically, it depends on the severity: a shallow hairline crack can be fixed by a pro with plastic filler or touch-up paint in minutes for a small cost. If it’s a messy, obvious crack in a prominent spot—like multiple fractures dead center on the front bumper—replacement is a must! Repairs might leave imperfect traces, hurting curb appeal. Cost-wise, a patch job costs around 100-200 RMB to get by, while an OEM replacement runs several thousand but is worth it. Last time I had a minor scrape and crack, I used a touch-up pen myself—decent results. But my buddy’s bumper had a gaping, bulging crack that split again within a week post-repair; only after replacement did it look right. Bottom line: for image and peace of mind, tolerate small cracks, but don’t hesitate to replace major ones—your car is your calling card!
