Some Pontiac G6 owners report experiencing front-end clunking noises and a rough ride, which may indicate issues with the shocks and struts. These clunking noises can stem from worn-out struts, jounce bumper problems, or damaged dust boots. Additionally, front suspension problems are frequently reported, necessitating inspections and potential replacements of struts, jounce bumpers, and dust boots. The average repair cost for addressing these clunking noises is around $500 at approximately 57,300 miles. Real-world experiences from owners suggest that they have had to replace front lower control arms, front wheel bearings, and struts due to suspension issues, which can also lead to tire damage. Furthermore, the clunking noise over small bumps may point to suspension problems related to worn-out shocks or struts, and troubleshooting the exact cause can be challenging, as it may involve sway bar links, sway bar bushings, strut mounts, or other front suspension components. It is recommended for owners experiencing these symptoms to consult a professional mechanic for a thorough inspection and diagnosis.
