Very polite, and extremely helpful with everything!
John took care of me. It was definitely an easy in, and easy out! Thanks again John.
Allyson was great thru my whole career inspection experience.
My car still isn’t fixed. And On Wednesday, October 8, 2025, I noticed my engine making unusual noises. Later that day, after getting off work, my engine light turned on. While driving on the freeway, my car began to slow down suddenly and then stopped completely on the side of the road.
I had my vehicle towed by AAA to Ontario Hyundai, where I was informed by the guy who picked up my car there was a puddle of oil underneath the car. On Thursday, Ontario Hyundai called to tell me that my oil drain plug was missing and there was no oil remaining in the engine.
Ontario Hyundai advised me to contact the last dealership that performed maintenance on my vehicle, which was Glendora Hyundai. Glendora Hyundai then towed my car to their location, inspected it, and confirmed the same issue — the oil plug was missing, and as a result, the engine seized due to lack of oil.
Glendora Hyundai informed me that they would not take responsibility and recommended I go through my insurance. However, this vehicle has only 12,000 miles and is a 2025 Hyundai Elantra, still under the manufacturer’s warranty. The only entity that has ever performed maintenance on my vehicle is Glendora Hyundai, which means the missing oil plug likely resulted from improper or negligent service.
I am requesting that Hyundai review this case immediately. Given the clear connection between the last service and the mechanical failure, I believe Hyundai and/or Glendora Hyundai should take full responsibility for repairing or replacing the engine under warranty. It’s been 7 days and they haven’t gave me a loaner car. And I desperately need a car and still nothing. My car is brand new. I’m very disappointed with Hyundai.
John was amazing. Best service I have ever had at a service dealership. I also witnessed him interact with his employees. With his employees, he is kind, mentoring, and helpful.
I have been coming to this dealership for many years. Previously, when anything needed attention like the air filter or the cabin filter or something like that needed to be changed, the service department would call you and let you know and if you wanted to do so you could say go ahead or another time, thanks. Mine really needed to be changed but I was told when I got there to pick up the vehicle so now I have to make another appointment & go there on another day and spend an hour or more till that service is completed, when just a phone call or even a txt message could have taken care of the problem today while my car was already there for the oil change.
I don’t know why or who has changed that policy but maybe someone needs to think about it.
Other than that everything went very smoothly and the service personnel who help me, was a very nice gentleman who took care of all my concerns and made sure everything was good and called me to let me know when my car was all done even though I did get txt messages also.
Allyson was nice & professional. Service for oil change took about 2 hours. Smooth process and everything was straight forward.
Keep up the GREAT CUSTOMER SERVICE
I’m very satisfied with Saul’s service
Had a 2:30 appt. My car sat for 1 hour before service started.
Allyson was great and positive
I am very pleased with the service. It is better than it has ever been - and I have been bringing my 2016 Sonata there for nearly 10 years. Christian has been extremely helpful and professional.
Cardinale Hyundai always gives the best customer service! Service Director John Tait assisted me today. I asked to be Ubered home, not knowing that you no longer offer that service. Mr. Tait did not hesitate and ordered me a Lyft driver to take me home. I found out he paid for my ride himself. What a wonderful man Mr. Tait is. His selfless act of kindness did not go unnoticed.
John Tait was excellent. He ensures that my previous visit from a different location does not occur at Glendora (bad service from the past location I usually go). He is very polite and professional. He did not overpromise on time, which I appreciate for being honest. I will certainly return again for my next due service for my car.
Your personnel is fantastic. I drive almost 2 hours to get to you every time I need service because of them. I always always always stop in to see Ping. The gentleman who checked me in today had such a great attitude. It was worth the drive and fighting the traffic both ways.
Thanks for squeezing in the wheel alignment ...
I went to pick up my car and I signed the paperwork that they fixed it and when they tried to pick bring me the car. It didn't start so I had to leave with a loner. I
Great fast service that we needed due to an urgent out of town trip. Thank you very much
Excellent work. I can feel the difference with the drive. Thank you so much
