Many have noted the need for multiple replacements within a short timeframe, with one owner replacing their driver front window regulator four times in just two years and another three times in two months, indicating a recurring problem. Additionally, some owners emphasize the importance of careful installation, as improper reassembly can lead to further failures, exemplified by a user who encountered issues after a small clip fell out during the replacement process.
