I have taken my car to mechanic and they have told me that my car is leaking gasoline. They recommended that I go to the dealer. When I called the dealer they told me that I would have to pay for the diagnosis. This is obviously concerning as gasoline fumes are toxic. There has been no warning lamps turned on this whole time but can definitely smell it when I finish my ride.

What component or system failed or malfunctioned, and is it available for inspection upon request" My engine stopped working while I was driving on the highway from Texas to Norman. This happened when I tried downshifting from 6 to 5. How was your safety or the safety of others put at risk? I had to find a way to maneuver from the fast lane to the side of the road without putting myself or any other road user at risk. Has the problem been reproduced or confirmed by a dealer or independent service center? After several failed diagnoses from different specialists such as auto locksmiths and other mechanics looking at the alternator and starter as possible causes of the problem, I had to have it towed to the Hyundai dealership in Norman to have it diagnosed and I was told that it was very likely to be an engine recall issue with a motor inside the engine having locked up. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was inspected by Hyundai Norman and they confirmed that it was the engine recall issue, but after sending it to Hyundai headquarters, they are unable to work on the problem due to my vehicle having a salvage title. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" There were no warning lamps, messages or symptoms prior to the engine failure

The engine and yes it is. Because my car turned off in the middle of the loop on the highway when there was a lot of traffic and we could have gotten hit. No it has not been. No it has not been. We were driving on the highway then the engine started sputtering and it wouldn-??t go faster then 40 when I tried pulling off to the side that-??s when the engine, battery, and oil light turned on and after that the car just shut off and wouldn-??t want to turn back on.

My 2015 Hyundai Sonata has recently been having both electrical and engine problems. Roughly a month ago, I had my vehicle completely stall in the middle of the highway. I lost power and a bunch of lights came on at once. Thankfully, I was in the right lane so I was able to safely get off the road even though I had many other cars speeding around me. I had no acceleration, I was just cruising off the highway at this point. Thankfully, my brakes did still work. Engine light and a bunch of errors turned on but went away once I pulled off and restarted the vehicle. I pulled off the road and once I decided to try and start it and go again, my car felt like it had hardly any power the whole way home. Fast forward to last weekend, I was driving home and my car would not accelerate. The engine light comes on and this time, my acceleration didn-??t completely shut off, I was just very limited. I had to ease into the gas because I felt like it was having a hard time shifting gears and keeping up with the RPMS. I felt uncomfortable pushing it above 50. As I got close to home, I noticed a knocking noise in the engine. I plugged one of my code readers in and it spit out 7e8, 7e9 and I believe it was p1326. Super rough start and feels like it-??s going to break down if I try to drive it. I-??ve left it parked since

I am unsure what exactly happened but it is giving an error code for the engine sensor. I was driving the expressway (55-65MPH) and my car went directly into safe mode. Which I didn-??t kno what it was til later. I went from going expressway speed to almost getting t-boned getting off of the exit ramp as I was unable to accelerate over 2RPMs. So my acceleration would jolt my car when going over 2RPMs. I made it to a gas station where I had my mechanic friend meet me. He said I had no oil. We put 4 quarts in and it barely did the job! I had gotten my car serviced and oil changed not too far from when my car began to -??shut down-??. So oil is in the compartment, the engine light turns off. Well then I-??m driving the expressway AGAIN thinking the problem is solved but also curious WHY and HOW I had no oil. All of a sudden the car goes back into the mode. Engine light comes on an I am once again going de-accelerating in traffic on an expressway. I get off an exit and make it home in back roads. I had to pay for rentals and I was unable to get it to the Hyundai manufacturer. I got it to another certified mechanic which stated there is an oil leak somewhere but is unable to be found. As the 4qts added days prior, was almost gone again. The engine sounds awful, there-??s rattling noises, noises sounding like a fan is broken but still spinning. There was absolutely NO warning signs prior. Nothing was on, nothing was off, absolutely NOTHING to forewarn me of this awful situation until it decided it was going to safe mode on the expressway out of nowhere. I owe thousands of dollars in rentals, I can-??t afford to even pay that off! For Hyundai to diagnose my car, they wanna charge 80$! When I already have the error code from the previous mechanic. I don-??t have the money to be doing this funny business. The car actually turned off when I was driving it and was in like an idle mode or something. I have no clue. Nobody has any idea where the oil goes. It isn-??t showing smoke anywhere

I have about 119,000 miles on my Sonata. One day while driving in normal conditions my check engine light illuminated and my RPMs were limited. I was Able to limp it home and park it. I hooked Up my OBD11 reader and it gives me p1326 code for knock sensor. After some investigation I read Hyundai has a recall for excessive rod bearing wear that leads to engine failure. I-??ve checked my VIN with this recall and my 2015 sonata does not qualify even though it has the same engine and make as the recall covers. Knock sensor has been replaced and of course it wasn-??t the problem as you can clearly hear the knocking in the engine.

My vehicle consumes oil in a very large amount. This has been happening since I bought the vehicle. Have had it checked numerous times. No oil leaks, no bad parts. I have to add 1 quart of oil every week to my car and I only drive locally. Mechanic states it is a common issue with this make and model of car. Nothing can be done except check oil levels daily. This is costly over time and worries me that if I dont keep a watch then my oil level will be too low and my engine will blow up. Blogs have also verified other owners have the same issue. Need something done about this issue. Why isn't there a recall to fix issue?
