Car has been having a myriad of problems that seem to be related to the electrical system. First warning sign that something was wrong was the car wouldn’t start up immediately after turning the car off. We had to wait between 5 and 20 minutes before the car would start up again. It was also revving up briefly at idle. Brought it into the mechanic, they replaced the power steering pump. We told them about the issues with turning the car on, they said they didn’t see anything.
Car worked fine for a couple of weeks, then when we were driving a longer distance (more than an hour drive) the tire pressure alert light went on. We were close to our destination, so we drove and parked, and the tire pressure was a little low. We were asked to move the car to a different spot in this lot, and it wouldn’t turn on. When we came back to the car (this was after flying out of down for four days) the car started up fine, and we filled the tires with air.
Next time we went on a longer drive, the tire pressure alert light went on again, but we checked the pressure and the tires were fine. This light turning on issue has continued, without seeming to be related to the tires actually losing pressure at all.
A couple of other problems that may be related. One, the car completely stalled out once at an intersection, and the battery warning light went on. I turned the car off, waited 60 seconds, then turned it on again and drove home just fine. Also, the right turn signal is flashing at double speed on the dashboard, but there aren’t any issues with the headlights or taillights themselves that would cause the light to flash at double speed. The left turn signal and the light on the dash flash normally.
I’m worried that this may be indicative of a larger problem in the electrical system, and since the mechanic told us the first time that they didn’t see any issues I wanted to get a second opinion before I brought the car in again. I also don’t really have a lot of money to spend, so I need to know if this is a critical issue or just something I can ignore until I get a new car early next year.
