2019 Hyundai Santa Fe

Oil Pan leaks after an oil change. Oil pan has a hairline crack just below the drain plug after normal tightening of the plug. Excessive oil was found on my driveway. No obvious engine damage, considering the vehicle was only moved from one spot to the other. The dealer stated the oil pan isn't covered under warranty. I simple internet search revealed there was a high number of complaints. It was a "Do It Yourself repair." The cost to fix was to replace the oil pain, new tools and 5 quarts of oil.

Engine Failure. Engine stalls during deceleration. If it doesn’t stall while braking, it immediately stalls around 5 mph when I come to a stop sign or red light. Vehicle start/stop button will not work to start the vehicle back up. It is to sit for 10-20 minutes and then it will start. If I don’t let it sit, it gives me a message on the dash that the vehicle is already on/running even though it is not. I have done regular maintenance and have had it serviced 4 times for the same issues. It has 126,000 on it. The dealership said it was the oxygen sensors and spark plugs. We had those fixed and the problem continued. The dealership is now wanting me to pay $11,000 for a used motor to be installed. Check engine light keeps repeating oxygen sensor malfunction. This has been happening since July of 2022.

I purchased a pre-owned certified 2019 Hyundai Santa Fe from a Hyundai dealership on 10/13/2020 and the vehicle had 21,770 miles. Then on 10/25/2021 (vehicle mileage was 31,950), I was driving my vehicle on the onramp to i-10 West lanes at Gessner Road. As I was accelerating at 40 mph to enter the freeway, my car engine seized and immediately I lost the ability to accelerate since the engine died. I immediately pulled over and had my car towed to the local Hyundai Dealership, HUB Hyundai Mitsubishi West. The Hyundai Dealership Service Manager, Daniel Castillo (832-739-6353), inspected my vehicle and after an inspection of the engine/underside of the vehicle, Hyundai found no damage or impact on the vehicle or the underside of the vehicle besides a missing drain plug. Their analysis concluded that the full result of the mechanical issue with the engine was a result of the missing drain plug which caused the oil to leak from the engine. Hyundai denied the warranty on the engine citing due to the drain plug issue is a direct result of a third party, Brake Check, that recently changed the oil (See attachment). The Brake Check Store #545 (11564 Westheimer Road, Houston TX 77077) had conducted recent oil changes performed on the vehicle on 12/8/2020 when the vehicle had 24,300 miles and on 5/5/2021 when the vehicle had 27,681 miles. I filed a claim (#3419328-1) with Brake Check for the damages however after 5 months of correspondences I was denied since I could not prove they did anything and the drain plug was missing. I also tried to file a claim with my personal auto insurance carrier, Progressive, however I was denied since the claim did not involve an accident. There was no warning lights that ever appeared on my dash prior to the incident. However, when I did go home that evening, I noticed a fresh large oil stain on my driveway were my car had previously be parked. The oil stain just occurred that day (See attached photo)

2019 Hyundai Santa fe first owner after each use of the Auto Stop/ Start feature is guaranteed that in 24-48 hrs the car will stall at stop lights and take anywhere from 15-20 min to restart. The power to the electronics continues but the engine can't restart from the stop. It appears as of the feature takes the power from the alternator, starter and battery and drains it until the car can be restarted. Once it starts it drives well until the system is engaged again. I have chosen to not use the system and the car has not stall however once the use of the Auto/ Start Stop system is engaged for a day or two it will stall the vehicle from a stop mostly at stop lights after so much time on standby mode while using the Auto Start / Stop system. Dealer can not recreate the issue.

The contact owns a 2019 Hyundai Santa Fe. The contact stated that while at a complete stop with the auto engine Start/Stop feature activated, the vehicle would intermittently shut off upon depression of the accelerator pedal with several warning lights illuminated on the instrument panel. The contact would be forced to turn off the vehicle and open the driver’s side door to reset the vehicle; after multiple attempts, the engine would restart and resume normal operation. The contact had taken the vehicle to two separate dealers, Freehold Hyundai (4065 US-9, Freehold, NJ 07728) and Greg May Hyundai (1501 TX-340 Loop, Waco, TX 76712)] on multiple occasions but neither dealer was able to duplicate the failure. The manufacturer was also notified of the failure and provided a case number. The contact was referred back to the dealer for assistance. The vehicle was not repaired. The failure mileage was approximately 40,000.

On 3 different occasions my vehicle has not restarted at a stop light after the idle stop and go feature turned the car off. I can’t to a complete stop, the car went into idle mode, then wouldn’t restart when I hit the accelerator again. I put on my hazard lights so cars could go around me and all the lights on my dash were flashing, brakes would not engage and it took several attempts to restart the car. The car has also not turned on 4 times when I first get in and go to start it. All the dash lights go on then as well and takes several attempts to start the car. I took it to the dealer and they could not find any issues. It is scary to drive as I fear it not starting after coming to a stop and being stuck on a main road.

Was driving and the car started stuttering. When I came to a stop the car would not move, a message flashed across the dash saying something about the auto stop feature was active and I had to put the car in park or neutral in order to drive again. Has happened numerous times almost daily. In order to stop this from happening you have to remember to turn the auto stop feature off.
