2007 Hyundai Sonata: grinding or squealing brakes

Filed Jan 22, 2018 · Brakes, Suspension · 180,000 miles · NC

There have been various problems that were discovered recently mostly based on the rear suspension and shocks. The brake lights have gone out many times and the alignment is frequently incorrect, and so the tires go through a lot of wear. The most recent tires were placed 9 months ago and already have terrible wear from both the suspension and the alignment. Whenever the car is in motion, the car does not drive as smoothly as it should and bounces lightly. There is loud noise whenever driving over speed bumps as if the tire pressure is poor. There is also a grinding noise when the car turns somewhat sharply. Many of these problems have existed for a while but were only diagnosed today at a midas auto in wilmington, nc.

When there is moisture in the air, my car battery and seat belt warning lights come on. I lose my power steering, my wipers go very slow and a belt starts to squeal. Also, after about 30 minutes, the radio stops working and all indicator lights come on. When it is raining, I am unable to use my defrost or air conditioning as well.

The engine started making metallic clicking and knocking noises about a week ago. I took it to my mechanic and by then it started squeaking and squealing. He said it was catastrophic engine failure and asked if I had ever let it run out of oil, which I never did. When driving to my mechanic, lost a lot of power on an entrance ramp to highway and almost got in an accident. My mechanic never seen in an engine with < 200,000 miles unless an oil event, so he believes this was due to a manufacturing defect. It is interesting that the 2011 and 2012 sonata was recalled for exactly this type of issue as well. I wonder if the problems were also existing on previous year models, such as the 2007 model.

While driving down the freeway, car pulled to the left. It is still doing it to this day. Had to take the car back to the dealer after the dealer did a brake job at 77000 miles. Had to argue with the dealership to redo the rotors after paying money for a complete brake job. The dealership finally agreed to redo the job after a long argument. I am still having problems with brakes today. When making a right turn, can hear grinding noises. When backing up and coming to a complete stop, can hear grinding noises. I have had this car in for brake service many times. I hear noises from the back and front suspension that has been going on since 2009. After having the dealership change every gasket in the car because of leakage, I have been hearing tapping noises in the car, reported it to hyundai motor, but they have ignored this. When I called the dealership after they fixed the gaskets, the gaskets leaked again and they said it was not their problem. This car is junk and it needs to be taken off of the road.

I heard high pitched noise from rear while driving 2007 sonata gls. I found that the rear wheels were extremely hot. I was afraid the tires will catch fire due to the heat. I took it to the dealer in southfield michigan. The manager said that it would cost me $300 to replace rear pads and they were not covered under warranty. Rear brake pads essentially were 95% worn out. Front brake pads were minimally worn during this time period and were ok. I got them replaced at "napa complete car care center" for $176 in oct 19, 2009 when it had 17,513 miles on it. At 40,042 miles while driving from detroit to milwaukee, I heard dreadful grinding noise. At "car-x auto service" in milwaukee they found the same problem with rear pads while front pads were ok. One rear pad was almost bare and others were more than 95% gone. I spent another $350 and this time the rotors also have to be replaced. There is definitely a design flaw and it is a safety issue due to heat which can cause tire fire. It seems the rear pads stop moving freely after certain pad wear. It could be too much hydraulic oil pressure in the rear brake lines or there is some defects due to ABS system. Hyundai must own this problem and fix this issue for good. Environment al (salt, water etc) effect is the same for both front and rear brakes. Front brakes do not need any adjustment or lubrication and they are ok. Why would only rear brakes need cleaning and lubrication at every 5000 miles as suggested by the dealer? In my driving for 40 years I have never seen this issue in any of the other vehicles I drove. On checking internet discussion boards I found that this issue is common and hyundai is not doing anything. This is not fair at all while consumers are holding the bag with perpetual expensive repairs and fear of being stranded and tire catching fire.

Right rear outer brake pad seized in the pad holder, grinding the rotor. Dealer repaired the brakes and charged me $ 400.00 even though the vehicle was still under warranty and should have been repaired free of charge. The front pads were only 50% worn and they do most of the stopping. Now hyundai dealer says that the hyundai sonata vehicle should have rear brakes cleaned and lubricated every 15,000 to 20,000 miles at my expense, to prevent "lock up". Hyundai does not mention this type of maintenance anywhere in it's maintenance schedule. After checking on the web, I find that this is a common safety problem among hyundai owners who are being ripped off by hyundai who refuses to repair this defect under warranty or recall the faulty brake calipers. I live in a rural area and mileage is 90% highway, so there is minimal usage of the brake compared to city dwellers, yet the brakes failed prematurely.

My 2007 hyundai sonata gls has defective rear brakes. I purchased the car in march 2008 and at 15,000 miles the brakes started squealing. I took the car in to the dealer in september 2009 and was told the rear pads were frozen which was causing the squealing. The dealer cleaned and adjusted the rear breaks. In june 2011, when stopping at a red light, the rear brakes suddenly started to stick and make noise as if metal was rubbing on metal. This really concerned me since I had my family with two children in the car. This happened with the car having 36,000 miles on it. I went on-line and googled to see if anyone else had this type of experience. I noted hundreds of similar complaints. Car experts mentioned this is an engineering design fault, which hyundai has failed to responsibility for. I called the dealership to schedule an inspection and asked the service representative if they had encountered similar issues with other customers. He said he was not aware of this brake issue. I had a hard time believing him since this issue appears to be a common occurrence with many hyundai sonata gls owners. Could this be a hyundai money earning scam? Hyundai needs to recall these cars due to the serious safety issues due to the faulty rear brake design! Safety! Safety! Safety! I hope something gets done!

Failure of visor on 2007 hyundai sonata. This first failed while under warranty and was repaired by the dealer. Now it has failed again. The visor drops down obscuring the driver's vision.

My 2007 sonata had only 18,000 miles on it when the rear brakes kept squeaking & locking up. This wore the pads down and they had to be replaced.I was told this happened because the sliders were rustin up and stopped working. I argued with hyundai that this was not normal and they said it depended on the driver. I am 65 years old had many vehicles, and have never rode the brakes, nor changed my driving habits. Now I have the problem again at 28,000 miles and my brakes are actually burning at times. The smell is terrible. I feel that this is a defect and also a safety hazard. My car bucks at times and I think that I may have to replace the rear brakes again. I am afraid to drive the car right now. I can't afford to fix the brakes again at this time. Please advise.

We own a 2007 hyundai sonata with 16,000 miles on it, barely 2 years old. The brakes had a squeal at about 15,000 miles and we couldn't put our finger on the problem. At 16,000 miles the rear wheels began grinding and I called cochran to have it fixed. They set me up with an appointment the next day. They told me my back brakes were worn and the rotors needed cut. This has to be some defect in the braking system, I've never had to replace brakes on any of my cars under 50,000 miles. They said it was not a warranty problem and charged me $225 for the repair. I think hyndai should put out a recall on these calipers hanging up on the 2007 sonata, and reimbursed all of us that have had this problem.
