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
What sound does a bad starter make?
A failing starter often clicks when you turn the key-but it might also produce a grinding or whirring sound, or no sound at all. If your engine won't turn over, schedule a diagnostic with Autowise Automotive to determine if starter replacement is needed.
How do I unlock the steering wheel if it's stuck?
Apply pressure to the brake and turn the steering wheel slightly while turning the ignition key. This typically releases tension in the steering column and unlocks the wheel. If it doesn't work or the battery is dead, contact a professional to avoid damaging the ignition system.
Battery FAQs
What should I avoid when replacing a car battery?
When replacing a car battery, avoid letting tools bridge the terminals-it can cause sparks or electrical shorts. Make sure the battery is properly secured before connecting cables. Unsure how to replace a car battery safely? Our team is here to help with expert, affordable installation services.
What's the most common mistake when jumping a car?
The #1 mistake is connecting the jumper cables incorrectly-reversing the positive (red) and negative (black) leads can cause serious damage to your alternator or battery. Always double-check your connections and avoid using damaged or low-quality cables. If you're unsure, it's safest to let Autowise Automotive handle the jump-start for you.

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.
