2000 Hyundai Sonata Problems

What owners report

Owners of this model year most often report rust-through of the front subframe and frame rails, which in many complaints led to a control arm separating, the front end dropping, or a wheel coming loose. These reports cluster at higher mileage on older vehicles and often surface during routine service, alignment work, or state inspection rather than as a sudden event. A separate, smaller group of complaints describes stalling and loss of power, and another describes airbag warning light and non-deployment concerns.

   Body and structure

   Rusted-through front subframe and frame rails

   • 114 complaints (41%)
   • median 120,000 mi at 9.3 yrs old (98 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $1,700 (median of 12 quotes)
   • filed 2006–2019

   Complaints describe rust holes in the front subframe, crossmember, or engine cradle that are found during alignment work, oil changes, tire service, or state inspection. In many cases the rusted metal let a control arm or A-arm separate from the frame, so the front end dropped, a wheel collapsed or detached, or the vehicle could no longer be steered or driven. Owners report that dealers and mechanics described the corrosion as severe and unlike what they would expect for the vehicle's age, and several say they were told the repair would cost well over a thousand dollars or that the car should not be driven. Mostly reported between roughly 70,000 and 160,000 miles, typically on vehicles many years old and often in states that use road salt.

   Recall 09V124000

   What to check: Have the front subframe and frame rails inspected on a lift for rust holes and flaking metal, especially near the control arm mounts, and ask whether the subframe has already been replaced. Check whether the vehicle was ever registered in a road-salt state and whether recall 09V124000 applies to its VIN.

   “2000 Hyundai Sonata sub frame rusted out, this vehicle is used by my son to commute to college daily and it's a miracle that he didn't have an accident. The right front tire also needs replacing even though it is almost new due to the damage caused by the sub-frame literally falling apart . I see this has been investigated before, why was no recall issued?”

   NHTSA complaint #10260938, filed 2009-03, 98,000 miles

   “The sub frame has rusted out on my 2000 Hyundai Sonata. I have been told it is very dangerous to drive. I purchased this car 5 yrs ago from a dealer in lexington, ky. I have been told it is highly unusual that a car that is 8 yrs. Old would have such a severe problem and that I should not keep the car, or that I should replace the frame which will be very expensive to do.”

   Suspension

   Control arm, crossmember and rear axle corrosion

   • 130 complaints (47%)
   • median 116,946 mi at 9.2 yrs old (110 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $1,800 (median of 15 quotes)
   • filed 2002–2022

   Complaints describe the vehicle pulling to one side, tires squealing in turns, or a loud noise followed by the front or rear end collapsing. Inspection commonly found the subframe or rear crossmember rusted through with the lower or upper control arm separated, and in some cases a wheel sitting visibly out of position. Owners report being told the corrosion was the cause and that the vehicle was not safe to drive until repaired. Typically reported between about 100,000 and 175,000 miles on vehicles roughly eight to fifteen years old.

   Recall 09V1240001 related service bulletin

   What to check: During a test drive, listen for clunks or grinding and check whether the car tracks straight; then have the control arms, crossmember and their mounting points inspected for corrosion. Ask for records of any subframe or suspension replacement.

   “I was using the as normal, then the car began to pull to the right. My first thought was that I needed an alignment, but as I was pulling into a store I heard a pop and then the right wheel would not roll. I then contacted a tow truck to have it towed. I got the car a Hyundai Sonata lifted on jacks and jack stands an noticed rust and corrosion on the subframe and seen that the arms connecting the wheel components to the frame had broken.”

   NHTSA complaint #10287241, filed 2009-10, 141,908 miles

   “I was pulling out of a gas station into a very busy intersection during rush hour traffic in my 2000 Hyundai Sonata. I then heard a snap, a grinding noise, and I could no longer accelerate my car. I was almost hit by several cars passing by at high speeds that did not see my car because they were coming around a corner. Two men stopped behind me and pushed my car back into the parking lot of the gas station. I called a tow truck, and they looked at my car the next morning. …”

   Electrical system

   Stalling and loss of power while driving

   • 30 complaints (11%)
   • median 77,745 mi at 7.3 yrs old (18 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2000–2012

   Complaints describe the engine cutting out or losing power without warning, sometimes at highway speed and sometimes when pulling away from a stop or turning through an intersection, with the check engine light coming on. Several owners report the mass air flow sensor or its connector wiring was identified as the cause, and some say the vehicle was not covered by the related recall because of its VIN. Others describe repeated stalling after parts were replaced. Mostly reported between about 70,000 and 100,000 miles, with a few at much lower mileage.

   Recall 00V259001

   What to check: Ask whether the mass air flow sensor and its connector wiring have been replaced or the related recall performed, and have a scan tool check for stored codes. Note any hesitation or drop in power during a test drive.

   “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. …”

   Brakes

   Brake roughness and reduced stopping

   • 9 complaints (3%)
   • median 79,100 mi at 5.3 yrs old (4 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2000–2010

   Complaints describe pulsing or a shimmy through the wheel when braking, a low pedal, and in some cases grinding noises with the vehicle failing to slow as expected. Owners report rotors being resurfaced or replaced, sometimes more than once, with the problem returning, and say they were given explanations such as driving style, water, or heat rather than a covered repair. Reported from very low mileage up to around 110,000 miles, with repeat repairs noted over time.

   What to check: Check for pedal pulsation or vibration when braking from highway speed, look at rotor condition through the wheels, and ask for brake service records. Have the brake and power-assist systems inspected if the pedal feels low or firm.

   “Both power steering and power brakes failed at the same time in my teenagers Sonata. Fortunately my son was only going around 25 MPH at the time and used the parking brake to stop. The Hyundai dealer says there is no connection between the two systems. Is there a NHTSA record of this occurring previously in the Sonata?”

   NHTSA complaint #10136208, filed 2005-09, 58,200 miles

   “Brake rotors are warpped and causing a low brake pedel and a dangerous shimmy in the wheel when ever I try to stop. They resurfaced both front rotors on 4/11/01 with 12,400 miles. At 29,000 miles the problem came back and they refused to fix the problem.first they stated it was caused by my driving, then I was told it was caused by going thru puddles. Then I was told that it was caused by heat and they do not cover heat related problems. The rotors are covered for 5 years, 60,000 miles, but not for the above reasons.”

Buying note. The most important thing to establish on this model year is the condition of the front subframe and frame rails, since that is what most complaints centre on and repairs can be costly; a lift inspection before purchase is worthwhile. Confirm which recalls have actually been performed for the specific VIN, since several owners report their vehicle fell outside the covered build or registration range.
