Rear subframe structural damage per class action lawsuit bacca v. BMW of north America, llc, case no. 2:06 cv 06-06753 ddp ajw(c. D. Cal. ). I brought my vehicle for maintenace repairs and inspection at a private repair shop and notified me that there is evidence of rear subframe damage during their inspection. BMW did not notify me of this very typical issue of their BMW 3 series models 1999-2006. This is not a typical issue in automotive manufacturing and should be continued to be address by BMW north America due to the compromise of safety to the owners and the public of these vehicles. I have attached a pdf of the class action lawsuit letter regarding the structural issues of the automobile. This obviously was not addressed by BMW properly and should be continued to be addressed as the issues are still relevant up to now. This still raises a safety issue since these models are still being sold today. I've also attached a current photo of my vehicle that shows the evidence of structural damage under the rear subframe of the vehicle. I would greatly appreciate you help in getting this issue resolved with BMW of north America as so prevent further damage and prevent any major accident from happening. Thank you! clarence trinidad.
