Hybrid system warning, shut off don't drive!!! light came on car shut down while in reverse, it was fine in drive! took it to the Hyundai in mesquite TX where I've had numerous issues in the past but had to go somewhere close! they couldn't find a diagnosis went through all the codes, said it wasn't shutting down for them and it was an oil pump and oil assembly $1,904. 49 minus the $150 diagnostic to not even tell me why it shuts down in reverse giving a whole other issue with the car that isn't a part of the reason I took it in! never again will I buy a Hyundai!.

2 Oil Pump problem

Failure Date: 02/26/2016

I have been notified by Hyundai motor America that my car is part of NHTSA campaign 15v-568. The issue is metal debris from the manufacturing process causing premature wear and possible engine seizing. The dealer has informed me that the will evaluate the engine with a "sound" test, only, taking about 15 minutes. This being the authorized method from Hyundai to this dealer. I assume that NHTSA has approved this method of evaluation. This method of testing will only identify those engines that have already experienced enough excess wear to cause unusual noises. This dependent on miles driven which will vary significantly among the number of vehicles effected. Metal debris blocking oil passages will not be detected by this test. Crankshaft and bearing damage due to metal debris that will be a long term problem will not be detected by this noise test. Vehicles with low mileage such as mine may not have enough damage sustained to cause any detectable noises at this time. The proper evaluation of this potential problem would consist of removing of the oil pan and inspecting for debris, disassembly of the oil pump for inspection, removal of all connecting rod bearings and inspection for metal debris or premature wear. This process would provide a more reasonable assurance that a future engine seizure would not occur. This problem represents safety uncertainty unless properly evaluated, which I do not believe is being done per your approval to this manufacturer. If possible, I would like to have a copy of your written approval to this manufacturer to use the sound test for this important safety issue. I am available to discuss this matter at any time [xxx] thank you information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6). ?.

3 Oil Pump problem

Failure Date: 08/07/2015

On August 7, 2015 at approximately 9:30 pm, I was coming back from running an errand with my 16-year old daughter in the car with me. I made a right-hand turn when suddenly, all of the lights on the instrument panel illuminated and the engine stopped. Additionally, I lost all power steering, etc. I was able to maneuver the vehicle to the side of the road immediately, but almost got rear-ended by a pickup truck that was following me. I turned off the car, let it sit for a few minutes, and started it up again. The car seemed fine at that point, and I was able to continue my short drive back to my home (approximately 1. 25 miles). When I arrived at home and placed the car in park, the oil pressure light was flickering slightly. I turned the car off and went into the house for the night. The next morning (8/8/15), I checked the oil level in the engine, and noted that it was slightly above the fill line. I added some synthetic oil to the engine, checked the level and noted that it was adequate. I started the engine to go run some errands. The car seemed fine at first, but when I was approximately 5 miles from my home, the oil pressure light began to flicker again while the car was idling (at a stop light, etc. ) I called my husband right away, who told me to bring the car home. I noted that the engine had somewhat of a ticking noise while driving it. When I was approximately a quarter-mile from home, the engine started knocking/banging very loudly. I immediately shut the car off, called my husband, and called for a tow truck. I had the car towed to my mechanic's shop. On Tuesday, 8/11/15, my mechanic removed the oil pan and informed me that the bearings were failing, which caused metal shards to clog the oil pump filter, and he also noted that the oil pan was full of shards. This car is a safety hazard and needs to be recalled!!!.
