2023 HYUNDAI ELANTRA Complaints

The car has been making clicking noise when braking or acceleration for about a year. I had all recalls software updated. I have brought it in multiple times. First saying a wheel bearing needed replacement, then a lose bolt. It helped for a while and then the clicking started again. Then the system failure occured recently and all the lights came on. The dealer currently cannot figure out what the issue is. The ABS light is on and the brakes don't seem to be working properly. I can't safely drive the vehicle and have no car to drive now. I have had the car a little over two years so lemon law most likely does not apply to this situation.

Car was breaking hard because of Active Assist despite that no car was in front. It was breaking consistently until I finally was able to disable the Active Assist. Luckily, there was traffic and driving at less than 20mph but this also happened some time last year at the same area where there was no traffic and was going at a minimum speed of 45mph and to have the Active Assist break hard put me at great risk of getting rear ended. I have footage from the dash cam which I unfortunately cannot attach as it's more than the 10MB limit.

The contact owns a 2023 Hyundai Elantra. The contact stated while driving 70 MPH, the vehicle lost motive power and stalled. During the failure the check engine warning light illuminated. The vehicle was taken to the local dealer to be diagnosed. The contact was informed that the cause of the failure was due to faulty motor mount bushings. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 290.

On July 28th 2024, I took my new 2023 Hyundai Elantra to its first oil change at a Take 5 oil change center. They replaced the oil, filter, checked the fluid levels in my car, and topped the fluids off. That evening, I noticed there was a liquid leaking from behind the passenger side tire, and at first thought it was water from the A/C, but in the morning, I noticed a puddle of liquid was under the car. I went back to Take 5 on August 5th and informed them that I believed there was coolant leaking from the vehicle following my oil change. The worker checked and said my coolant reservoir was completely empty, and he refilled the coolant and told me to take it to be diagnosed at a full service auto center. On August 13th I noticed there was a smell of burning metal coming from the engine bay when I turned the car on and took it to a Firestone where they informed me that the radiator cap had failed and was no longer holding the pressure in the radiator, and that almost all the coolant had leaked from my car. I had the radiator cap replaced and kept the original to take to the Hyundai dealership to see if this was a manufacturers defect or the result of improper handling by the Take 5 worker.

Since 2/2/24 13 episodes of all safety features failing including blind spot monitor, lane keep assist, forward collision warning, and others. Last occurrence on 8-8-24. On one occasion the car failed to accelerate in the middle of an intersection, the car did move slowly and operation returned to normal after turning off the car and pressing the 12V reset button. Diagnostic codes found on car APP include both C164286 and C164202 for all 13 episodes. Despite being told this code is "for the speed sensor because it saw a voltage drop from the battery system" the dealer claims there is nothing they can do because they can't recreate the problem. This is highly dangerous to my family and others as the safety features can prevent accidents. The most concerning is the car suddenly losing acceleration as this could potential happen where there is no safe way to get off the road in time prior to an accident. This loss of acceleration has been reported by many other people on the Facebook group I am a part of called Hyundai Elantra Hybrid Owners. The loss of safety features occurred after all recalls were performed as of 8-8-24

The vehicle was not taken to an independent mechanic or tire repair shop. The tire was not inspected and was not replaced. The contact stated that the failure was the third Kumho Solus 205/55/R16 that had developed blisters on the sidewall and failed.

When vehicle gets wet, knock sensor trips and puts the vehicle in limp mode. Making it very dangerous to drive since everything is underpowered and makes it hard to get up to speed, shift, etc.

When passing under a bridge or traveling underneath train tracks, the forward collision warning would activate causing the car to brake when no other vehicle is in front
