Maintenance Warning Signs in Merrillville, IN

Maintenance Warning Signs in Merrillville, IN

It’s understandable that when you drive around Merrillville, the maintenance for your Lexus won’t be at the front of your mind. That’s why we here at Lexus of Merrillville have prepared this short overview to help you recognize some of the warning signs. If you have any questions after reading this, be sure to Ask a Tech!

Dashboard Warning Lights

Dashboard warning lights are the most plain to see as they are the car’s way of communicating to you. There are a wide variety of lights that will each tell you about a different part of the car. When you ignite your vehicle, these will typically all illuminate, which is when the vehicle is diagnosing itself. If everything is in working order, then they’ll turn off, but if there’s an issue then one or more will stay on. Some common ones that you may run into are the battery light, which depicts the energy component. This can usually mean that power isn’t being stored or transferred properly. The oil can picture turns on when the oil pressure has dropped in the car, which can mean that either it needs to be topped off or that there is a leak.

Unusual Noises 

You should also keep an ear out for any strange noises that you could encounter on your way to Hidden Lake Park. When you press down on the brake pedal, you could hear a grinding noise, which means that the brake pads have been worn down. If you hear a clicking sound when trying to start the car, then that could be an issue with the battery not delivering the charge needed for combustion. If you hear knocking or whining from the engine, then this could be a loose or cracked component that needs to be taken care of. 

Handling and Performance Issues

While driving down I-65, your vehicle may pull to one side, which can mean there’s an issue with the wheel alignment. You can also feel this if the steering column shakes while driving. Should you notice that the vehicle is harder to maneuver or if it’s experiencing worsened fuel efficiency, then that can be an issue with a number of things. The vehicle could have poor tire installation, low tire pressure, or transmission issues, which can all be tended to by our Service Department.  

Smells and Smoke

Malodorous scents or smoke in the car can also be grave signs. If there’s ever smoke rising from the engine, then that could indicate an overheating engine and needs to be taken care of immediately. If you notice a sulfur or rotten egg-like scent, then that could be the battery leaking. If it's a mildew like smell, then that could mean that the cabin air filter has been clogged. Should you notice any of these issues, then don’t hesitate to schedule a service appointment

This is the 2nd vehicle we have bought from Johnny V. We simply can't say enough good things about this guy he is the best. Very professional and personable. Very knowledgeable about the cars, and had answers to everything we asked. They didn't have the car combo we wanted and he took the time to find it. Other "big" dealers don't/won't offer the service to locate what you need. We then met with Joe to sign the papers, he was helpful without the hard sell. Very professional as well. One last thing... they offered great advice on local pizza! We will be back! Thanks!

Very happy with the service I received when buying my pre owned vehicle! From the front desk receptionist which was very nice and helpful to the sales representative James Tucker who helped me with purchasing a new vehicle. I already knew what I was looking to buy walking into the Lexus Dealership. But James made the process simple and easy and I cannot recommend him enough to anyone looking to buy a car. When the time comes again to upgrade my ride I will be returning to Lexus of Merrillville.

Talk about a breath of fresh air!! I, like everyone else, am not a fan of the car search process, however, Noelle and Joe at Lexus of Merrillville made this process PLEASANT!!! I got a call from a website inquiry and they played ZERO games! Noelle has been with Lexus for almost 2 decades and it shows in her professionalism, knowledge, and grace! It was a pleasure chatting with her let alone doing business with her. I was confident that she was taking good care of me and being transparent. Speaking of transparency, the business manager Joe S played no games! He knows his stuff! He advocated for what I felt comfortable with but also gave me transparency! He answered my question and made sure I understood the process and wasn’t just signing papers! If you want a seamless process, GO TO LEXUS OF MERRILLVILLE!!

I am in the process of purchasing an electric vehicle with Lexus of Merrillville. I am waiting for the vehicle to arrive at the dealership. I had to write this review to tell you about the AMAZING experience I had with Douglas Onyekachi! I came in uneducated about the difference between electric vehicles and Plug-in Hybrid vehicles and when I left, I understood things so much better. Douglas made the experience unlike car buying experiences I have had in the past. During the test drive, we talked and laughed like we were old friends. Douglas was patient with me. He made sure I got the exact vehicle I wanted. I am a return Lexus customer. It is really nice to see the service I was accustomed to in the past is still in place! My old salesperson was Mark Lovejoy who I purchased two Lexus vehicles from (Marck unfortunately passed away). Many thanks to Douglas, my new salesperson, for my wonderful buying experience!

I would like to start by saying this place is amazing from customer service to closing the deal. I came in because I wanted to upgrade my mother's car. Mother's Day is next week, and I wanted to give her her dream car. The sales associate was welcoming from the time I pulled in the lot. The sales associate took the time out and listened to what I wanted to do for my mother. He showed us every car we wanted to see. The crazy part is the very car I wanted my mother to have, I didn't even ask to test drive. But it worked out because it was the very car I drove off the lot in. The GM and finance team where total amazing. I would come back here for every car moving forward. Don't walk, please run here to buy your Lexus. Lexus of Merrillville, you guys rock. Thank you for the GREAT experience.

I was looking for a 2026 Lexus IS 350 F sport with specific options and finish and Lexus of Merrillville came through for me. They did some research, were able to get the vehicle that matched my preferences, and installed an additional option I wanted. The customer service when I took delivery was top tier. Douglas Onyekachi was my salesman from the start and was outstanding to work with throughout the buying experience. I will certainly look him up when I ready for another vehicle.
