Suspension Noise problems of the 2006 Hyundai Sonata

Front suspension "wheel control fork" bolts must constantly be tightened every few weeks or the bolts will come loose causing a "knocking" noise while driving. If left untightened the fork will come disconnected from the suspension causing loss of control and possible car crash.

Vehicle front suspension makes sound when we drive on uneven roads, bumps. Checked with couple clinics, all says design fault. I have this sound for 2+ years and I am worried. Front both tires suspension makes this sound.

While driving home from the grocery store, my esc light came on. Had trouble steering the car and there was a squealing noise coming from the back end. I was informed by my mechanic that the problem is that the rear axle housing is cracked/rusted and that the wheel is crooked. The car is currently undriveable. I had read in the paper about rust causing problems with the rear suspension control arms and believe that I am experiencing the same problem. I contacted the Hyundai dealership where the car was purchased to see if this would be covered under the 100,000 mile drivetrain warranty (car has approx. 80,000 miles on it), but was told that they weren't sure. I have an appointment scheduled for repair, but will not be able to have it done, unless it is covered.

The contact owns a 2006 Hyundai Sonata. While driving 20 mph, he heard a loud banging noise coming from the rear of the vehicle. The contact stated that the noise was louder while making a turn with a passenger seated in the rear. The dealer inspected the vehicle on two occasions; the first time they were unable to diagnose the failure and the second time the dealer adjusted the rear suspension. The suspension adjustment failed to solve the failure. As of October 9, 2007, the dealer had not repaired the vehicle. The failure mileage was 12,000 and the current mileage was 16,997. The dealer stated the front right door lock inoperable, passenger seat area makes a rattling sound, right trunk trim vibrates when vehicle in motion and hears knocking sound in the engine.

Thumping noise and vibration from rear suspension on bumpy roads. Feels similar to what you might experience if the gas tank were loose, or exhaust hit undercarriage of car, or if spare tire were loose in the trunk. Became more noticeable in warmer weather, and after 5000 miles. Seems to have no effect on handling or stability. Returned car to dealer. Dealer acknowledged several complaints, but insisted that it was a characteristic of suspension design and nothing was wrong nor could anything be done to correct the problem.

Rear suspension has annoying and loud thumping noise when going over bumps under 40 mph. Started noticing noise within 1000 miles after purchasing vehicle, which was on 10/26/05. Manufacturer has admitted the problem in a bbb arbitration hearing, case no. Hyu0641565 dated 04/27/06 and stated it as a characteristic of the vehicle. Also in a telephone conversations with a regional representative and others as a problem. Took the problem to dealership, who could not find the cause and did not put it on the work orders. Therefore, I lost the arbitration hearing, even though they told me personally that Hyundai told them not to do anything, because they do not know what to look for in terms of the thumping. What automobile manufacturer would incorporate a noise in their vehicles as a selling feature and state it's a characteristic of the vehicle? if Hyundai does not know the cause of the rear suspension noise, then they do not know if a safety factor is involved. The suspension could and probably is defective in some way.
