To whom it may concern, I am writing to formally file a complaint regarding the safety and reliability of my leased vehicle. I have been experiencing ongoing issues that pose a serious safety risk. Approximately two months into my lease, I began experiencing electrical problems with the vehicle. The most concerning issue is the car's tendency to shut down unexpectedly while driving, which has escalated over time. Each incident has resulted in significant concern for my safety and that of my passengers, as well as for other drivers on the road. I visited the dealership to report the problem and get the car serviced but I was unfortunately met with unprofessional behavior, and was asked to leave the dealership without resolution. Despite my repeated attempts to address the ongoing issues, I have been unable to find a suitable solution. Additionally, the lack of available loaner vehicles has made it increasingly difficult to have the vehicle serviced. Driving a vehicle that is prone to unexpected shutdowns is not only inconvenient but poses a significant safety hazard. I am deeply concerned that continued use of this vehicle may lead to an accident, endangering myself, my family, and others on the road. Given the seriousness of these safety issues, I am formally requesting an investigation into these matters. I believe it is essential for this situation to be addressed promptly to ensure that necessary measures are taken to prevent accidents and protect consumers. Please let me know if further information is required to support my complaint. I appreciate your attention to this serious matter and look forward to your prompt response. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The DASHBOARD keeps changing while driving, and the dealer states they have fixed it. I have had 2 dashboards replaced since I purchased the car (1 year) and this unsafe while driving my GPS keeps changing while driving. This is VERY UNSAFE! The SUNROOF WILL NOT CLOSE, until the next day. It rains inside my car because it will not close, so I can not use my sunroof PERIOD. This is one of the reasons I purchased the car. NOW, my CHECK ENGINE LIGHT is on for EMISSIONS SYSTEM (IT IS CRITICAL THAT YOU TAKE CARE OF THIS PROMPTLY TO MAINTAIN SAFETY). The dealer held my car for 3 days, and now they state "they requested the part, but no one told them (from the manufacture) that the part is not available due to problems with the current part and they have to rebuild the part, and it's on back order". Now, I'm riding around with a check engine light on until Nobody knows when! I don't trust this dealer, who told me its okay to drive like this AND we will call you when the part comes in. They stated they fixed my dashboard and its still not fixed. They don't know when, they will have the part for my sunroof or my emissions issue, and my dashboard is still not working and I have to borrow someone car to travel because my GPS and Engine light is on. A brand new car and it has been in the shop (6 times) more than any car I have owned. I pay my car not on time and I keep my car serviced, but this not fair to me and I need help please.
