Example complaints

Electrical system: “I purchased a 2015 BMW i8 (salvage title) from Parkline Motors. The vehicle history (Carfax) disclosed prior front/right damage, which I accepted. However, the dealership failed to disclose critical safety-related defects associated with that damage. Shortly after taking possession of the vehicle, I experienced a malfunction in the SRS (Supplemental Restraint System), which controls the airbag system. This is a serious safety issue, as it can affect proper airbag deployment. …”

Electronic stability control: “Vehicle is saying chassis stabilization error which I believe is the same as dynamic stabilization. I did some research and have found my make year and model was recalled for the specific problem. The Bmw dealership near me is requesting 2,500$ to fix this problem when it is suppose to be free of charge. While I started my vehicle one morning the light came on. It was not while I was driving. It first says initializing stabilization and then it says malfunction.”
