Alternator, Starter & Car Battery Replacement Services
Alternators
Your alternator powers essential systems while your engine is running. If your lights dim or your battery drains unexpectedly, it may be time for alternator repair or replacement. Our expert team will test your alternator and get you back on the road safely.
Batteries
Your car battery powers everything from the ignition to headlights. If you're jump-starting regularly or seeing a dashboard warning light, it's time to consider a car battery replacement. Our team offers fast battery testing, replacement, charging, and recycling services in Hayward. Not sure how often to replace a car battery? Most drivers should check their battery after 3 years and consider replacing by year 5-especially in extreme climates or with frequent short trips.
Starters
The starter gets your engine going. Clicking sounds or a failure to start can signal a faulty starter motor. We'll diagnose starter issues and repair or replace the component as needed to ensure reliable starts every time.
Car Starting FAQs
How do I unlock a locked steering wheel?
Press the brake pedal and gently turn the steering wheel in the direction it moves slightly while turning the key. This relieves pressure in the steering column and allows the wheel to unlock. Never force the wheel or key. If the battery is dead or the key will not turn, consult a professional technician.
What does a failing starter sound like?
Common signs of a failing starter include a single clicking sound, grinding noises, or complete silence when turning the key. These symptoms often indicate a starter problem that should be inspected and serviced as soon as possible.
Battery FAQs
What are common mistakes when jumping a car?
The most common mistake is reversing the jumper cable connections. Always connect red to positive and black to negative. Using low-quality cables, allowing the clips to touch, or attempting to jump-start a battery with visible damage can cause serious electrical damage. When in doubt, have Autowise Automotive perform the jump safely.
What should I be careful of when replacing a car battery?
When replacing a car battery, avoid touching both terminals with the same tool, as this can create a dangerous short circuit. Never drop the battery, and do not reconnect the cables until the battery is securely mounted. If you're unsure about the process, let our technicians handle your battery replacement professionally.

What People Say About Us
I've been going to Autowise for years. The people who work there are friendly and professional. Right now my family owns and maintains 5 cars. Autowise services all of them, and I have never been stuck by the side of the road in any of them because they do such good work. That is very important to me, especially when my children are behind the wheel. As far as price goes...cars are not cheap to maintain! I would recommend that you shop around. You might find a better price, but remember the old saying...You get what you pay for!
Professional & experienced staff!!
I take my two cars to them, I always had good experience with them. They identified the issue and proposed the fix, estimation and upon approval they did the fix. It worked great. I feel , they are honest hard working and only recommends what needs to be changed to keep the car in good condition. The quotes are reasonable This makes me trust them.
The shop is a great shop they have excellent mechanics that really know your car inside and out there little spendy but I recommend them!
The folks at AutoWise are terrific! They diagnose problems brilliantly, repair what needs to be done, but don?t ?push? to have unnecessary work done. They can take you home so you don?t have to wait there. All work on my 2003 Saturn Vue has been done by AutoWise and my old SUV runs well! Estimates on work are accurate and work is done in a timely manner. Because it is a family business, clients are always treated with courtesy and warmth. I highly recommend AutoWise and wouldn?t go anywhere else!
Good people and great service. My wife and I have been bringing our cars here for years. Mike and Laurie are a pleasure to deal with.
