“aste): The vehicle has a serious pulling issue while driving, which was not corrected with alignment and poses a safety risk. Additionally, the windshield was scratched by faulty wiper blades that impaired visibility — the dealer later reimbursed me. Lastly, the driver-side running light was not functioning, which creates a hazard and may violate federal lighting safety standards.”
