Q: Lights burn out every time I start the car

asked by on

This is going to sound weird, but one of the lights burns out every time I start the car. Sometimes the head lights/tail lights, sometimes blinkers, etc. There are no codes. What causes such a thing as this?

A: The starter requires a lot of battery power...

The starter requires a lot of battery power to turn over your engine, and if the ground for the starter, battery, body or engine is loose, then the starter will use another ground if it finds one. You may be using the lighting system as a ground for the starter every time you try and start the car. Have the battery and engine grounds checked by a professional, such as one from YourMechanic. They will be able to diagnose your electrical issue and let you know what repairs are necessary.

Q: My car makes a whining noise in first gear

The first thing to do is make sure it's the transmission, and not the alternator or power steering pump. These components also produce whining sounds sometimes. Having done that, does the transmission only whine while it's in gear (forward or...

Q: Won't shift when moving forward

The seller probably had the right idea. 170,000 miles is really right in the life expectancy for a German automatic transmission. Especially now that the dealers are not recommending regular transmission services anymore. It sounds like you may have a...
