Drain system has been cleared of debris (leaves, etc.) however, same problem still happens. Problem: when it rains, water appears in the floor of the back passenger side - has been as much as 3/4 inch after a prolonged rain. was told that a connecting part in the assembly was deteriorating. can this problem be repaired?

It has over 100,000 on it. Minimal maintenance.
Sears just checked it out, ran an engine cleaner and replaced some fluids. Battery is old but it's not due to battery. Sometimes it restarts, but now it will not restart.

not registering nor is my tachometer. What could cause this ?

I turn on the heat/AC and the AC light flickers, but immediately goes away. Heat does not work and AC switch will not even light up if I hit it. In the past few months, the heat/AC would cut off randomly while I was driving, but come back on after a while. I talked to my regular dealer about it and they said that it may be a short in the switch. It appears that whatever the problem is has gotten worse and that my AC/heat has stopped working completely. I would like to know the problem and a ballpark estimate on how much it would be to fi it, if possible. It really is going to be hard to defrost my windows without either of those working. Thank you in advance.

Replaced my radiator, which was cracked. I think the crack was because the fans are not working.

Then the RPM SHOOTS TO 4000. replaced timing belt.

says they are causing the tires to cup

gas gage levels are erratic
falsely reported alternator problem
falsely reports low tire pressure

can't find any holes that might contribute to the problem and no one seems to be able to come up with a solution

The noise first started out that I noticed like my tire rubbing the wheel well.

check engine light went on after getting battery changed code#p0106 what would make thiscode come on how do I fix

checked under carriage and also column to see if "worm" is a problem. mechanic said it is not. what should i check next. noise occurs at startup when wheel is turned in an idle position.

new regulator and motor works

this started happening after i took a jump start because of a low battery.....and also the fuel level was low....since replaced the battery and fueled up...but problem persists

Why is my car falling apart ? Steering coupler, cv axles, shift pad, fan modual runs hot , loud noises when you hit bumps and going 65 m ph , loud clicking and vibrating in steering wheel ,car shakes, and the tires wear out , need new tires every year when others have their for much longer ! I am a stay at home mom and the car is only used for short distants.Husband has work truck ! But I bought this car used and the warranty ran out and now the night mares begin, I would not suggest noone to buy a Sonata of any make or model , cause they seem to fall to pieces ...then it becomes your problem that you can't afford to fix, broke down car with babies and a high car note and insurance, recalls don't come out fast enough but it's funny to read that others are having the same trouble ! What to do ?

Just bought this Sonata a week ago. Found that passenger side power locks do not work on front nor rear doors. Tried locking/unlocking from all doors with same results. Driver side locks working fine. Suggestions as to what the problem is? I'm thinking this will not be covered in the used car warranty. Thanks.

It stops under 45 mph. Feels like rear end is swaying more then front.

Replace upper arm control

Whenever you try to put gas in the car, the gas pump nozzle doesn't keep the seal unless you put your whole weight on it to keep it in, and if you let the suction go the gas spurts out. The check engine light stays on.

Where is the fuel relay switch located I looked under the dash but did not see it there, is it on the fuel delivery assembly in the tank?

sometimes it starts but it only idols

At stops it idles a little rough.takes off slow..what could it be...every time I drive it but this just started...use to run good no problems before

I'm second owner; service warranty thankfully covered engine replacement. Certified dealership wants to discuss offering "good deal" on another vehicle. I wanted a break from car payments, but don't want unexpected major mechanical problems to develop (that probably won't be covered under service warranty.) NOTE: Recently had transmission flush to coincide with engine replacement.

Replaced water pump and timing belt. Set timing as instructed. Now I have "high" idle -6000 RPM. What do I need to do?
