I submitted via fax earlier this week a formal letter to Mr. Exler the president & CEO of mbusa and, cc'd Mr. King of the NHTSA that included information about known critical safety issued these vehicles had prior to mbusa importing them to the United States. Mbusa failed to disclose these known issues and, chose to importation these vehicles violating vehicle importation rules. Yesterday-January 31, 2019 I received a call from a representative of mbusa stating he was calling on behalf of Mr. Exlers office concerning my letter. I will not be intimidated by mbusa while seeking the truth on why mbusa allowed these vehicles to enter the usa knowing these critical safety issues existed while misleading consumers and, the NHTSA. On January 21, 2019 my vehicle had what is described by mbusa as a catastrophic failure when the entire brake system failed. This failure could have killed me - and, other motorist. Mbusa has replaced the sbc unit at least 6 times and, still the issue and, other persist. The vehicle has been driven on average 4,000 miles annually. How many failures must happen before mbusa is fully investigated? they refused to provide me any information on the vehicles except the 4 year warranty period. Once I complete my research on these vehicles I will submit my findings to the NHTSA & Ms. King

They have offered no assistance in repairing this safety/mechanical failure. This car should not have these sensors going bad this quickly.
