I bought my car back in june (its a 2012 brand new) around 2 weeks after I bought it I started hearing a poping clunking sound from the front end at low speeds. Found it was a common problem with these cars and took it to the dealer to have it fixed. The dealer said it was the upper strut mounts and replaced them. So it hasnt been an issue for about 6 months but now im hearing the same sound as of yesterday. Is there any other part that needs replaced besides the mounts, or just any info would help.
