Very friendly staff, very straight forward, upfront, and very welcoming. Not pressured what so ever, and I will be coming back for more service.


Excellent service, I mean there's nothing better. These people take care of you. They looked over my car when I took it in and I just feel very comfortable with them. The owner at Hye Tech takes good care of me.


John has always been helpful and fair about price. He is extremely credible when it comes to car knowledge and is very easy to talk to.


John and his team are the best!


John is a very caring person, takes good care of his customers. I enjoy talking to John.

Our review of Hye Tech Auto Repair found a shop where experience abounds. The average experience of John and his two technicians is over 25 years! Along with all of this experience is a commitment to ongoing training to keep up with all the latest technology. These guys not only work together, they train together, completing various classes each year. Combine these skilled technicians with all the tools and diagnostic equipment we would expect to find in one of our Certified shops and you have a recipe for success. Their excellent Customer Convenience score is due in part to a convenient location near other businesses and services, a local shuttle service, WiFi internet access, and Saturday business hours.

Obviously a fuel leak is very serious and dangerous, it's hard to speculate what is leaking. You should bring it into a shop to have it checked properly and repaired as needed. It could be a number of things such as the fuel pump seal, filler tube, fuel line, fuel filter and so on.

Over filling the oil could cause a leak to develop from the valve covers which will spill into the spark plug tube. I would more then likely think that it's from your valve cover gasket, but it should be checked out. BMW is notorious for oil leaks.

As your engine gets older it is normal for it to consume some oil, it is also possible that you may have oil leaks. Average vehicle can consume about 1/2 to 1 quart of oil between oil changes. If you hear noise from the engine such as a knocking or loud ticking noise there may be more going on with the engine that requires attention.
