. On 9/16/05 after coming home from work in the evening, my Hyundai 2000 Sonata had a electrical fire. Luckily I was getting out of the car when everything under the hood exploded into flames. I was able to move the car away from the house. The fire department came quickly and put the fire out. The car was totaled. Before this I didn't have any electrical or engine problems.
Saturday ,07/19/03 I parked my huynday Sonata 4doors, 4 cylinders at best buy plantation (fl) parking lot @ 1:00 pm to visit my at&t wireless staffer at this store. When coming back @ 2:30 pm the car had got on fire. The hood was opened by plantation fire deparment to put the fire out. Everything was burned. Total loss of vehicle.
While driving at about 35 MPH the engine stalled then restarted while in motion. Then the vehicle started hesitating form a stand still and felt like it did not want to accelerate. I contacted the dealer and the following day they found a faulty cam sensor which they replaced. Two days later the vehicle started hesitating from a standstill and then started stalling when at a stop I.e.red lights. I contacted the dealer on 6/28 and they checked the car the next day. They agreed with the hesitation problem and said the history code for the cam sensor failure had not been cleared. Seemed a little fishy to me. I asked if this would remedy the problem. The response was if it didn't give them another call. I said what if I am on the highway and it fails. …
Engine stalled as I was turning in an intersection, I avoided a crash. Reported to dealer as it happened 3 more times. They replaced my battery and gave me a carfax report and denied any recalls, even though I showed them a printout of one on this website. Check engine light on several times ,taken to auto store and put on diagnostic machine, maf sensor defective as stated on printout x2 separate occasions .still stalls at lights, and also stalls when either changing to reverse or vise versa. My kids are scared to ride with me. This stalling is happening on approx an every other day basis.dealer has been made aware and denies anything is wrong according to "their" diagnostic computer, yet will not allow me visual confirmation of such. I think I am unfortunately the victim of a lemon, and if I could afford to I would just drop it off at their doorstep and let the finance company know. …
I pulled out into the road from a stop sign and my car loss power as there was oncoming traffic almost coming to a complete stop. I had to come completely off the gas pedal and stop, as I resumed the car began jerking and slowing resuming speed. I was almost rear ended with my kids sitting in the back seat. The also did the same thing again as I begin to drive up a incline/hill, it loss power. I experience this problem at least 3-4 times a week. I have researched that there was an electrical problem in 2000 Hyundai Sonata, v-6 cars and contacted the dealership and that stated that my car was not included in the recall. I was also told that I had several repairs done from previous recalls. I informed the customer service personnel that I had not received any notifications in the mail regarding recalls. …
I have a 2000 Hyundai Sonata. I have had several sensors replaced in this car already. It is something electrical or another sensor, go figure. My wipers stopped working, and my wiper fluid pump also went out. Had local auto shop replace wiper fluid pump, they tried whatever they could, then the wipers would not stop working,so they took out the relay switch.then my wipers start working and I can turn them off/on with out the relay switch in. My car power locks are not working either, which they did before. Then my car would not start for next three/four days, had to have it jumped each day. So I thought it was my battery or alternator, had those tested, it is not either of them. Then my car the next couple of day starts a little better, but still barely starting, and sometimes when I start my car, the power locks lock automatically. …
My Hyundai dealer has refused to honor their 100,000miles, 10 years warranty" many times that I bring the car to be fixed under the warranty since the car was only 8years old and 76,000 miles since 2008. They refuse to fix the problems that I experienced by saying my car is not listed in any recall campaign. Unfortunately this year, on 10/11/12, I took my car for an annual state inspection for 2000 Hyundai Sonata and it fails the safety inspection. Here is what it says: ***vehicle memo*** vehicle is unsafe to drive...rear sub-frame has hole rotted through... Due to the current financial situation, I don't know how I will get this car fixed because the car is now 115,000miles and 12 years old and I don't know if they will fix it. …
Tl contact owns a 2000 Hyundai Sonata.

Two big problems, first the current the entire frame on the ride side has completely rusted out and the bottom fell out of the car - before this happened the car was pulling to the right the car was unable to be driven and a frame is hard to locate because I was told this is a common problem with these cars - a 2000 Hyundai shouldn't completely rust from the inside - there is no rust on the car and it was kept in a garage I am in communication with the company to see what will be done, judging from pas experiences - nothing second issue: we had many problems involving the electric system the car would go dead for no apparent reason the car alarm would get stuck and you couldn't get in the car or start it the dashboard lights go in and out (mostly out now).
