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 Dallas. 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.
Battery Related FAQs
What can go wrong when jumping a car?
Incorrect jumper cable placement-reversing polarity-is a leading cause of alternator or battery damage. Use red for positive and black for negative, and never let the clamps touch. Damaged cables or corroded battery terminals can also pose a risk. For peace of mind, let Dennis Road Automotive perform the jump safely.
What precautions should I take when replacing a car battery?
Use insulated tools and avoid shorting the terminals. Handle the battery carefully to prevent drops or tipping, and always secure it before reconnecting the cables. If you're not familiar with replacing a car battery, let our trained team handle it with precision and care.
Car Starting Related FAQs
How do I release a locked steering wheel?
Place your foot on the brake and turn the wheel in the direction in which it has a little range of motion. This should ease the tension in the steering column and allow you to turn the key. Turning the key unlocks the steering wheel. Do not try to unlock your steering wheel without a key or if the battery is dead. This should only be done by a professional auto repair technician.
What are the warning signs of a bad starter?
A failing starter may click when you turn the key or produce a slow whine. In some cases, there may be no sound at all. If your car won't start and the battery is healthy, it's likely time to inspect or replace the starter motor.

If I could give them 10 stars I would! We had our check engine light on and were prepared for a $1,500 bill. They called back and a wire was not plugged in correctly so they only charged us for the diagnostic plus $45. What a relief! An HONEST mechanic. We are customers for life. And they gave my 2 year old and 5 year old sons brand new Hot Wheels in the package to play with.

Where do I start ADAM ADAM ADAM remember that name his customer service was outstanding, spectacular, and above and beyond, when I first pulled up he had a Genuine spirit, His presence made me feel very comfortable, I didn't get this feeling this guys just here to do a job and get paid, but that he has a heart to care about his clients, He listened, took notes, and understood what I was requesting fully. I told him how I went to another mechanic shop and how I was treated there and how much they were trying to charge me to fix an issue he emphasized with me and understood that not everyone have money to blow especially fixing unnecessary things that doesn't necessarily pertain to the issue at hand I was being upsold at another mechanic shop and over charged but ADAM rest assured he doesn't do that there he knows when you treat a customer right they'll continue to be loyal. I was expecting to have it in the shop for a while and having to Uber to work and back it gets expensive when you're 30 mins away from work. He was able to fix my Auto Stop Start and Check Engine light for dang near HALF the price of another mechanic shop quoted me and didn't upsell me and fixed it in 2 DAYS! He was so nice I offered a tip 3 times and he denied it real genuine he also checked in on me to make sure things were straight. I was extremely happy to know it's fixed and that I'm saving HALF the price I was quoted I found my Guy and Mechanic shop at Dennis Auto Motive HIGHLY RECOMMEND
I've trusted Dennis Road Automotive for many years, though it's been a while since my last visit, mainly because they're not open on weekends. I've always appreciated their straightforward service, and I still miss Riley, who brought a great personal touch to the experience. On my most recent visit, I was charged $374 for a new battery for a Lexus ES350. I'm not sure how that compares in today's economy, but it gave me the same feeling you get when dining out these days, quality isn't necessarily better, yet the prices seem to jump significantly. The work was completed, and the team was professional, but the cost left me wondering if the value aligns with what it used to be. I still want to support businesses that have served the community for so long, and I hope they continue to provide honest, dependable service at a price that feels fair in the current market.
