I was driving on the highway; the speed limit is 70mph. I had the sunroof of my 2017 Hyundai Veloster open to the first stage. The glass in the sunroof literally exploded, (it sounded like a gun going off) blasting shattered glass down on me and all of the interior of the car, (scared the [XXX] out of me!) Luckily, I wasn't hurt and managed to pull over without any traffic incident, but this could have easily caused personal injury or a collision on the highway at 70mph. It wasn't struck by anything, and the glass was in perfect condition without visual defects, i.e., chips, scratches etc. It has been turned into my insurance and I am going to request that the new glass gets a coating like the windshield to prevent the glass from coming apart like this in the event that this happens again. I think all sunroof glass should be treated this way from the factory, a broken window or sunroof is enough distraction while driving without being showered in glass.

Almost got into an accident with 2017 Hyundai Veloster. Car stopped accelerating. Car had service campaign to enhance knock sensor software to detect abnormal engine bearing noise before potentially "severe engine damage occurs." They did not explain engine could have issue. Engine oil keeps disappearing. I went more than 5 times no fix yet. One time they put a free oil change. I keep going to Hyundai and am told nothing is wrong with car by Hyundai dealer. Months later I receive a letter from Hyundai extending warranty due to connecting rod bearing wear for replacement of engine. According to Hyundai, " If abnormal engine bearing noise is detected, the Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Engine Protection Mode allowing the customer to drive to the nearest Hyundai dealer for diagnosis and repair. In addition, DTC P132600 will be recorded in the ECM. The vehicle can continue to be operated for a limited time in Engine Protection Mode, but it will accelerate slower and have a reduced maximum speed. Engine RPMs will be limited to approximately 1800-2000 RPM." My car is doing that. I told dealer. They tried to charge me to change my coils and sparkplugs and refused to check my engine unless I fixed that first. They said they don't know what's going on even though Hyundai sent a letter out stating engines will be fixed because of rod bearing wear. Hyundai knows that the engine is bad and extending warranty for engines but are not recalling the engines. People can die from this. Engine oil that leaks because of this can heat up and cause cars to explode/cause accidents.

While driving this vehicle, it suffered catastrophic engine failure, I had no low oil pressure or check engine warning lights until the failure occurred. I was stranded on the I-270 outer-belt of Columbus, OH during the early morning hours of July 20, 2022, That is a hazardous place to be with traffic passing my vehicle at high rates of speed. I checked my engine oil and there was nothing on the dipstick. The vehicle had not exceeded its oil change window. The vehicle has not been inspected by the manufacturer/police/or insurer. AAA Gahanna New Albany Service Center 614-750-8350 verified that the engine was blown. It is unsafe that and engine can be suddenly oil starved with no low oil pressure light, leaving the driver at the side of the highway amid fast moving traffic.

My accident the air bag did not deploy hitting another vehicle it deployed after hitting a curb which would have been 2 nd impact to deploy it should have come out then, the bar in the head rest came out which cut my head and I received staples in my head. What the other metal things that flew out of the steering I don't know but they cut and burned my arm very bad. I was going straight on a two lane street. When the car backed into to the intersection it did not come from my right or my left. I was 3/4 of the way across the intersection when this car appeared backing up. I could not stop in time and hit it in the rear of their car.

Panoramic sun roof shattered today, 8 Jan 2019. My car has 14, 200 miles on it. There was snow on the top of my car (on the sun roof). After my car was warmed up (and stopped at a stop light), I heard a strange crackling type noise. I did not suspect it was glass until I hit a bump in the road and then heard pieces of something falling onto the protective/retractable curtain of my sunroof. I pulled off the road and noticed the entire sunroof was cracked with pieces falling onto the curtain.
