2012 Hyundai Equus owner complaints

I am writing to log an immediate emergency update to my vehicle safety report regarding my 2012 Hyundai Equus Signature 5.0L. On Friday afternoon, July 10, 2026, Hyundai Motor America’s corporate office formally initiated a high-level Tier-2 supervisor review to investigate the severe powertrain safety hazard currently present on my vehicle—specifically, a catastrophic internal rupture of the transmission fluid cooler loop that has cross-contaminated and flooded my engine block infrastructure and main radiator with high-velocity metallic shrapnel. However, today, Saturday, July 11, 2026, the servicing franchise dealership, Patrick Hyundai, issued an immediate verbal denial of all goodwill repair or safety inspection coverage. This premature weekend denial represents a blatant, bad-faith a

I am reporting a severe vehicle safety hazard involving a sudden loss of motive power and extreme thermal failure on my 2012 Hyundai Equus Signature 5.0L. In July 2022, at 88,845 miles, an authorized Hyundai dealership replaced the transmission under a factory warranty event. Rather than replacing the transmission oil cooler assembly—which was contaminated with heavy metal shrapnel from the original mechanical breakdown—the servicing dealer chose to only flush the lines, creating a latent fluid restriction. After approximately 18,000 miles of operation, this restriction completely choked the transmission fluid pressure loop. The extreme thermal stress and back-pressure caused the internal walls of the transmission cooler to suffer a catastrophic structural rupture. This caused the transm

I was driving on the highway and my transmission due to a failed transmission service done to my vehicle caused my vehicle’s transmission to overheat a blowout my transmission cooler and mix coolant and transmission fluid unknown to me because of a clogged transmission cooler line improperly flushed instead of replaced by the Patrick Hyundai dealership there could’ve been and electrical fire or a crash due to these things.

From the desk of lmi's executive director: [xxx] I purchased 2012 equus on march 7, 2012 with 108,216 miles. The cars suspension started going bad as of last week. I brought the car back on march 20, 2020 to have a mirror replaced and to discuss the suspension problem. It?s been over a week and today them after a 45 minute drive I was told they had the wrong mirror...even though I spoke with the service person ([xxx]) and he assured me everything was in order and he even scheduled an appointment for them to replace the mirror. While I was there I showed [xxx] the suspension and I was referred to the sales manager. Talk to the sales manager and he showed no concern...the sales manager gave me a look like, so what do you want me to do about it. I stated my concern and that I've

My vehicle sways like a boat side to side no matter my speed, but on the highway it almost feels like I'm losing control. I have taken the vehicle to the dealership and after having it for 4 weeks they returned my vehicle back to me not repaired and no answers to why the issue started. I was told they were requesting an Hyundai field engineer to come out to inspect the vehicle but I have not heard from them in almost 2 months. *tr

After a few months of purchasing car the ecs light started illuminating which in return gave car a spongy, bouncy ride etc., height function would not work. After repairs were done 1st time around june-august of 2013 seem like every few months problem would occur again and again, latest being july 2014,car was placed in shop july 7th and car was just returned july 31st it has been an ongoing problem that I think will continue from my experience since purchasing car, I am no tech or engineer but for a fairly new car that's not that old this problem should not be happening, it is mind boggling. *tr

Following a slip on the road I am the victim of an accident on the edge of a Hyundai santa fe. The car struck the mountain, but the airbags failed to activate in the accident resulting in a frontal impact, which caused me serious injury. Why the airbags are not triggered ?? The car made several rotations and suffered irreversible damage and despite everything the airbags were not triggered.
