2011 Hyundai Sonata: gas smell in the cabin

Filed Jul 21, 2026 · Airbags, Fuel system · CA

I purchased fgis car from a used car dealership, for over $6,000.00 , which is not a ton of money, but plenty enough to not have instant issues. Since my purchase in june 30, 2026, i have already had all of these issues occur. There is white smoke coming from the left tail pipe, it is sluggish when you push on the gas, there is black soot constantly on my rims that is extreamly hard to remove, the high pressure fuel pump jas failed, I can tell because the oil is higher then it was when o had the oil freshly changed, and it smells of gasoline.inside the oil. The exhaust has stron smell of gasoline. My steering wheel has a loud clinking noise everytime I go over a speed bump on pull into my driveway. Just so many items consistently needing repair or replacement, even though I just had the fuel system cleaned, the oil changed, and filters, and.oil filter too. I checked to see if any of my issues are covered by a recall warranty, because they all are recalled items for my car year, make, and model, but apparently Hyunfai is only covering these dangerous recall items for ul to 10 years. These items shkuld be covered longer, because my carfax states that at least one of these recalled items had already been changed in 2018, and is already broken again!! Hyundai should have covered these extreamly high wear out car parts for a longer period of time, or for the life of the vehicle, if every 5 years your replacing a $1000.00 part, not including labor, like the (HPFP) I was quoted by auto zone for over that price point!! "Ridiculous"! Another item is the air bag cover on the driver side windows area, of the body frame it is loose and keeps un-clipping, i am afraid that it is going to possibly just go off and kill me or something!! Very disappointed right now, that i cannot get any of these recalled items replaced by the manufacturer!!

Smell of fuel & starting issues. The car has been taken to the dealer multiple times regarding gas fumes and they could not find anything. And it is currently at a mechanic shop to for same reason. When you start the car it doesnt take long before the whole car smells like gas & the smell is so strong it is suffocating. The car is health & fire risk. Also the car sometimes doesnt want to start for days but the starter, battery, alternator all work & even the mechanic doesnt know whats wrong with it. Apperantly there is no recall & if you search online there are alot of people with same cars complaining about gas smell & starting issues..

I have had issues with this vehicle since oct 2019. At that time I had a recall for the hard knock sensor after that it continues to give me issues. The check engine comes on continuously every week. I fix one issue then the lights comes back on for another. My car shakes while driving like engine wants to stop, doesn't want to accelerate over 40 miles in the middle of the highway streets it's not safe for a vehicle to stop accelerating without any warning theirs other bystanders that can crash into me.I contacted hynduai every month since oct urging them to do a full diagnostic cause my vehicle already has 13 recalls on it previously and I strongly feel this vehicle is one of the defective ones. Hynduai keeps turning their back on me and tells me I need to fix this then this then that. I also have a fuel smell and a evap code that keeps coming on which this recall was supposed to be fixed and if it happend again its guarantee to be fixed again. Hynduai told me no. They keep turning their back on me. I fear that my vehicle will cause harm to me and others due to the lack of hyundai not taking my vehicle safety seriously.

In motion car surges and jerks forward randomly. There is a gas smell when driving and car begins to shake when engine is engaged. Backup camera will not engage at random times or car will not turn on with push to start system. Diagnoses engine and electrical issue but hyundai won't include in their recall campaign.
