Example complaints
Electrical system: “We heard a whining sound under the hood on November 1st, 2025. Prior to noticing this noise, there were no warming lamps or messages appearing. Following a short drive we smelled burning in the garage. We did not drive the vehicle the following day and intended to take it to our mechanic on Monday morning, the 3rd. Upon trying to start the car it was dead. We had to have it professionally jumped as standard jumping with our personal jumper cables would not start it. Our mechanic explained both the battery and the water pump would need to be replaced. …”
