What Our Customers Are Saying

Don't just take our word for it. Here's what our customers have to say.

Sarah C

ALWAYS excellent service and in a timely manner. They don’t overcharge or treat me differently because I’m a woman, which is so rare. Great prices and great people. I’ve gotten nearly all of my car repair done here from brakes to oil changes and never felt taken advantage of. Cannot recommend enough!

Celeste G

I've been coming to Japanese Engine for about 3yrs now for a variety of car troubles and they have never let me down. They are honest and true to their work. Rob and Karen never start a project without the owner's consent and always performs exemplary work. They have even gone above and beyond to look over the rest of the engine and inform me of other potential issues my vehicle may encounter. Great service, very helpful, and well timed project completion.

Frequently Asked Questions

How often should I get my vehicle serviced for regular maintenance?

Regular maintenance is crucial to keep your vehicle running smoothly and prevent costly breakdowns. We recommend following your manufacturer's recommended maintenance schedule, which can typically be found in your owner's manual. This schedule typically includes services like oil changes, tire rotations, brake inspections, and fluid checks. In general, a standard guideline is to have your vehicle serviced every 3,000 to 5,000 miles, but this can vary depending on your vehicle's make and model. If you're unsure, our experienced technicians can provide personalized recommendations based on your driving habits and vehicle specifications.

Why is it important to have my car serviced regularly?

Regular service helps prevent unexpected breakdowns, extends the life of your vehicle, and maintains optimal performance and safety. Routine maintenance can also save you money by catching small issues before they become major repairs. At J. E. I. Complete Auto Repair, we make it easy to stay on schedule with reminders and personalized recommendations, so you can drive with confidence.

What payment options do you accept for your services?

We offer a variety of payment options to make your experience convenient. We accept major credit cards, including Visa, MasterCard, and American Express, as well as cash payments. Additionally, we honor most warranty programs, such as Endurance, CarShield, CARCHEX, and Protect My Car, to help cover the cost of eligible repairs. Our goal is to provide flexibility and ensure that your car repair needs are met without financial stress. Please feel free to discuss payment options and warranty coverage with our friendly staff when you schedule your appointment.


Do you offer a warranty on your repair work?

Yes, we stand behind the quality of our work with a comprehensive warranty. Our warranty coverage varies depending on the type of repair or service performed, but it typically ranges from 90 days to 12 months or more. This warranty is a testament to our confidence in the expertise of our technicians and the quality of the parts we use. If you experience any issues related to the repair within the warranty period, simply bring your vehicle back to us, and we'll address the problem at no additional cost to you. Your satisfaction and peace of mind are important to us, and our warranty reflects our commitment to your vehicle's performance and reliability.

Can I bring my own parts for repairs?

No, we do not install customer-supplied parts. We only use high-quality, trusted parts sourced through our suppliers to ensure your vehicle’s safety, reliability, and warranty coverage. This allows us to guarantee the workmanship and performance of every repair we perform.

How long will my repair take?

Repair times can vary depending on the type of service and parts availability. We strive to complete most repairs as quickly as possible—often the same day for common maintenance and minor repairs. For more complex issues, we’ll give you an accurate estimate and keep you updated throughout the process.

Do you provide estimates before starting work?

Absolutely! We provide clear, detailed estimates before any work begins. Our team will walk you through the recommended repairs and answer any questions, so you can make informed decisions about your vehicle’s care.

Can you help if my car breaks down or won’t start?

Yes! We offer diagnostic services and can arrange towing if needed. Just give us a call, and we’ll help you get your car to our shop safely and efficiently.
