This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The brake pedal drops during braking with a clunk. The brakes are weak at that point but recover. I replaced the brake pads and rotors and master cylinder, still the same problem. It happens a lot. My wife won't drive the car anymore.
The contact owns a 2003 Hyundai Sonata. The contact stated that the brake warning light illuminated and the vehicle was leaking brake fluid. The contact also stated that the air conditioner failed. The vehicle was taken to an independent mechanic where it was diagnosed that the air conditioner compressor failed and the brake sensors were replaced; however, the air conditioning system was not repaired. The failure recurred. The manufacturer was not made aware of the failure. The VIN was invalid. The approximate failure mileage was 144,967.
My neighbors informed me that my brake lights were stuck on. One of them researched and read that it may be the M48 stop lamp switch. We found the plastic backing portion from the contact plate that pushes the switch in. It was broken in pieces and laying on the floor mat below the brake pedal. He replaced it with something that is temporarily doing the job. I will be taking my car into the Hyundai dealer next week to have this fixed. They will also be replacing my gas tank that got punctured while they were replacing the valve-canister cl, canister assy., and valve-purge contr. Back in Feb. 2014 when I could not easily get fuel into the vehicle. I believe the fuel issue should be a recall as well from all of the people I have seen on the internet searching for resolutions to the same problem with their Hyundai's.
Over the past year, while traveling at various speeds, in various weather conditions my brake pedal very sporadically will not depress. The pedal is solid and will not move/respond for between 1 and recently up to about 6 seconds, which is a lifetime when you are trying to stop a car at 55 mph. Two auto shops have driven the car and can not recreate or diagnose the issue. Based on my own research, I finally resigned to have the master cylinder replaced. However, while the mechanic was replacing the mc he noticed that the vacuum hose had a metal clamp near the mc end and the clamp had shifted down the hose. Inside the hose, where the clamp had been, there appeared to be a spring loaded valve, possibly an internal check valve, which was now "loose" in the hose. It seems that if the clamp is in fact keeping the valve in place and it slowly drifts overtime this problem is something that would only appear with older cars. Also, I've seen reports on internet forums where others have described the same brake problem, however there is no recall listed for this issue. I don't know how many incidents need to be reported before action is taken, but as this is a life-threatening problem I would hope you treat it with urgency and investigate it fully.
