My code check at a Goodyear dealer showed code P0087, a problem associated with the fuel delivery system in my Sonata. The car loses power when driving by not accepting gas to increase the speed. The Goodyear dealer told me he has seen this problem on numerous Hyundai.

Driving and vehicle lost power. Could push accelerator to the floor and there was no response. Happened while driving straight at highway speed and the car remained running but no accelerator response. Pulled to the shoulder and the car sputtered and acceleration control returned but car was running very poorly and acceleration control came and went. Obd2 code P0087 was read when check engine light came on the next day when trying to start the vehicle. All starts since the incident have been hard starts. The wastegate actuator sensor rod retainer clip was found to be missing, it was replaced and the sensor was tested to ensure correct voltage (between 3.9 and 4.1). Obd2 code was cleared and car ran ok for a test drive but the following day, all symptoms had returned and we again experienced no accelerator response. Retest of the wastegate actuator indicated the the voltage was still in range. This is a dangerous condition because it results in complete loss of accelerator control.

I have the hyundia 2012 2.0T. On 2 desperate occasions the car has filled up with gas fumes. I filled up the gas tank and started driving from las vegas to laughlin. It was over 105 degrees, which it is often in the desert areas. About 20 mins into the drive my wife asked me do you smell that it smells like gas again. We already had the car serviced for to other recalls. I said yes so we turned the air conditioner up. It got worse as we drove. Our eyesvstarted tearing up it was starting to get hard to breath so I pulled over and told my wife to get out and stand away from the car. I opened the his slowly to see if there was a leak or fire. There was none so we staed driving again and it proceeded to get worse we opened the sun roof and all the windows. Then we stopped in the city of searchlight to walk it off. Honest to god there was another newer Sonata 2014T parked next to us when we came out. He asked us how we like our car. I told him I love it but we were having gas fumes in the car. He said that he just left laughlin about 30 mins ago and that is the reason he pulled over. It happen to him a few times but it was to hard to breathe and his eyes started hurting. I said exactly. In was about 105 outside now. I called dealer, abc Hyundai. They know about the problem, it a gas exhaust ventilation problem. There is not a recall yet so I have to pay for it. I said what it's $135 to start. So I called both centennial Hyundai and las vegas Hyundai. They both know about the problem. First is it toxic "??? next when someone passes out or dies is that when a recall starts" one more thing that may be a recall due to safety if I lock my car doors with the remote then the rear passenger doesn't lock all the way. So I have to open the passenger behind the driver and manually lock it. This now triggers the passenger front to unlock.

Last year (2016) 2 months after I purchased my 2012 Hyundai Sonata my engine failed. I realized it was due to a recall on my car. I was not notified at time of purchase and car facts did not mention open recall. The dealer refused to pay or be involved in the fixing of the car or the rental. Even though I paid 2000 dollars out of pocket for an extended warranty. The Hyundai company completed the recall fix on my engine and my insurance company (state farm ) got the dealership to cover half the cost of the rental. This year (2017) almost exactly 1 year later I am driving 60 mph down the freeway and my engine fails once again. I had my car towed to the same merced Hyundai dealership hat "fixed" the problem last year. The problem is the fuel tank has metal debri in it from the time hey built the car and over time as it passed through your engine it breaks it down. The "fixed" the problem by replacing my engine block but not replacing he fuel tank so won't the problem just happen again? I am hoping they don't try to make me pay for it this time around. I would like to know my options for this situation and who needs to be held accountable.

The car suddenly turned 'off', lost propulsion and came to a stop in the middle of the road. The dashboard gas gauge showed approximately one quarter of a tank of gas but it turns out the tank was empty. The likely cause is a defective gauge in the gas tank.

The has to be something wrong with lighting or electrical system on my car. I have had to replace every headlight, taillight, brake light and license plate light, not once but several times for each one. Must have replaced 16 to 20 lights. Now the horn keeps blowing. I have had to disconnect the battery cable so it doesn't wake up the whole neighborhood.. I am taking it in to the dealer tomorrow. I would appreciate any feedback or if anyone else is having these problems.. this is not normal. Also, it loses power as I am driving. Feels like it is going to stall out, but then takes off again.

Boyfriend's vehicle. Check engine light came on and the code P0087 was noted by the obdii (fuel rail pressure low) mechanic originally stated that this was an "intermittent" problem and the whole system would have to be replaced at + $1200. This didn't make sense to him so he asked to be shown exactly where the problem was located, and what part was causing the problem. The mechanic could not give him an answer. "it's around this area" he replied as he waved across the center of car. He went to another mechanic and another after that. Only consistency has been the lack of know how to fix this problem. In the meantime, his oil is thickening and darkening, and his fuel is not giving him the mileage it should. It seems the only assistance anyone wants to give revolves around replacing the whole system, yet the servicemen themselves admit that they are uncertain that this avenue for repair is necessary. None of them can offer us a repair or replacement of the sensor itself. Finally, one mechanic advised us that under the P0087 error code the following could be causing the engine light to come on: 1. weak fuel pump, clogged filter or screen, restricted fuel supply line 2.faulty fuel pump driver module 3.faulty fuel pressure sensor. Unfortunately, this mechanic is a student and not certified to perform repairs. I verified his opinion thru obdcodes.com but was quickly disillusioned because again, no one is willing to check these causes individually. Finally my boyfriend was told to just buy a can of air spray to blow out any surrounding dust and then just let him 'reset' the check engine light and see how long it stays off. I know that this is wrong and have found a repair guide finally. But, I also now find service bulletin no.: tsb-15-01-010 component(s): Engine NHTSA id number: 10058132 that seems to be about this issue. How do we resolve this problem already?

  • 8,000 miles
On more than a dozen occasions since purchase, the vehicle has neglected to accelerate when the gas pedal is depressed nearly causing me to be hit by oncoming traffic. Additionally, the vehicle has slammed on the brakes at high rates of speed when the driver was barely applying pressure to the pedal; almost causing the vehicle to be rear ended. The vehicle has been inspected by two Hyundai dealerships for the issues; of which they claimed to have replicated. Both dealerships stated that it was normal behavior for the vehicle and there was nothing they could do to make the issues go away.
