2002 Hyundai Sonata: check engine light

Filed Aug 24, 2012 · Driver assistance, Electrical · 135,000 miles · TX

My car started getting erratic idling and then the engine light started to turn on. I got the spark plugs and spark plug wires replaced and then it mild down after around 1wk after, then the erratic idling while on drive or on reverse started again. Left it like that thinking it was maybe the fuel pump or something like that. Had my brother that is a mechanic check it and said he found the spark plug wires out of sequence, but after he made sure all were the correct order the same problem started again, same erratic idling and this time it really did feel like sometimes loosing power. It has gotten worse since then that I was driving, don't recall the MPH, but it must of been around 50 - 60 MPH cause I was on the freeway. The whole engine sporadically, in less than a split second, turns off then on. All the electric panel and the front dashboard and the whole car's electrical system turns off/on in a "blink of an eye". It made the car make an erratic and sudden stop, like if I had put the brakes completely or the engine just stopped that split second. Then it went back on and still driving. After that it did it about 2 more times like around those mins I was driving, about mins apart. After this happened, it's been getting worse and now the power shuts off completely and I have to drive to the side with no power on car. Then suddenly gets power again and I just start it again. I've checked the cables of batteries and they keep telling me I can't get the car checked for codes cause the engine light keeps getting reset since it looses power completely and they can't get any codes unless the engine light is lit up. Sometimes turning signal or putting the brakes or lights on make it stop or loose power completely.

Tl* the contact owns a 2002 hyundai sonata. When fueling the vehicle, gasoline regurgitates from the fuel tank. Also the check engine warning light was illuminated on the instrument control panel. Sometimes the vehicle will hesitate when attempting to accelerate, as if there was no fuel available. The dealer was notified, and a technician concluded that she would have to pay $900.00 to repair the vehicle. No repairs were made.. The failure mileage was unknown and the current mileage was 82878.

Engine light keeps coming on. Took for repair and the code states there is a problem with the air/fuel mixture. Auto repair shop asked if we turned the gas cap atleast 3 turns after last fill--yes we did. We previously were not able to pump gas the pump would shut off everytime we tried to pump. Auto repair replaced charcoal filters in the neck of the fuel tank has run fine since this engine light started.

Went to dealer for check engine light. I was told my subframe was rotting out. The dealer states they would replace the subframe under a " goodwill warranty" when asked if there was a recall or problems with the subframe of these cars I was told no.

Electrical system. I have already filed one complaint on the check engine light and the sensors. It has been in the dealership 9 times prior to this one. Now it is a cam sensor and I believe a speed sensor. Not only that but both wheel bearings are bad. It has roughly 78,000 miles. You can only get parts at a dealership. The parts are not only overpriced, but the dealership charges outrageous prices to do anything. You can unhook the battery and the light will stay off for a couple of months and then it comes back on. I take it to the dealership and they supposedly fix it and the light comes back on in a shorter amount of time than unhooking the battery. I have spoke with hyundai when the problems started and all you get is we'll fix it until the warranty is up then you are out of luck. I can't keep the check engine light off long enough to even sell it.

Consumer stated that she was having too many problems with her vehicle and does not want it anymore. The engine light kept coming on and she took the vehicle to the dealer, who stated the fuel injection system was going bad. The vehicle had only 300 miles on it at the time. Then after that was repaired. She drove it a while and the engine light started to come on again. This time when she took it in to the dealer, she was told the o2 sensor was bad. This also was repaired.

I purchased a 2002 hyundai sonata and have had nothing but trouble with it. To date we have had the o2 sensors replaced due to numerous check engine indicators. We have had the clutch replaced, the transmission replaced, the clutch depression switch after having the clutch and transmission replaced the switch failed to work consistently preventing the car from starting. After having the switch replaced, the very next day I smelled an electrical burning smell which then caused my headlights to dim the heater fan/motor to drop in speed and the windshield wipers to move very slowly. I brought the car to the dealership, houser hyundai of springfield, ma. And while waiting for the service bay doors to open the car was enveloped in a cloud of smoke the instant I turned the heater on (january 10, 2004) temp outside was -9 degrees. At any rate the service manager was notified the instant I smelled something burning but he did not see the smoke when I was waiting at the dealership the next day. He did admit to smelling the burning ??? But could not duplicate the problem when we left it to be checked and I was told there was nothing they could do. The old saying goes where there is smoke this "fire" so I am checking it off as such in this complaint. The car is and has been a saftey concern to me and my family. I have a co-worker and my wife as witnesses to both the burning smell and electrical "load" malfunctions due to what ever has short circuited and my wife in particular observed the "smoke" billowing from beneath the car on the day we brought it to the dealership. I fully intend to file a complaint as well with the massachusetts state government of which I am employed under the "lemon law." respectfully; dale wyman.

I have a 2002 hyundai sonata that I bought new in april of 2002. As of march of this year at 27,700 miles, it has been in the shop for the check engine light 5 separate times. The first time it showed an oxygen sensor. Within the next 100 miles it was on again, this time it was an evap code and they said it was the fuel pump seal so they tightened it. Within another 100 miles it came on again and was another oxygen sensor. It came on again after about 3 months (and around 9,000 miles) and this time it was the evap code again and they said that it was the fuel cap. This had to be ordered and I called back after three weeks and someone had forgot to order it so it after all took 3 months to replace it. In the meantime the car was detailed and the company unhooked the battery, the check engine light stayed off for a little over a month (the light was on when it went to the detail company). So the fuel cap was eventually replaced and the light came on again within 100 miles after. This time it was 3 different codes. One for another oxygen sensor, one for a throttle positioning sensor, and one for a fuel increment sensor. I am at 47,800 miles now and I am told that it could take a few months to get the oxygen sensor due to hyundai updating the sensor due to a defect. By the time my car is fixed, this time the warranty will more than likely be up or close to it and all I can get from hyundai is that they will fix it up to the 60,000 mile warranty and if the light comes on after that it is my problem. They say it is not a concern due to something different every time.
