When the ABS comes into play from heavy braking you will feel a pulsating of the brake pedal under your foot. This is the brake pressure, on off on off as the wheels stop start stop etc. The ABS will not control the vehicle direction but by allowing the wheels to turn under brakes and not lock up you have control of the steering and the direction the vehicle goes.The ABS will not stop you quicker and in fact on ice or loose surface the distance to stop will be increased. As I said all the ABS does is give you steering ability under brakes.. Take the vehicle to an accredited brake shop and have the ABS tested if you feel that it is no operating properly
Thanks for choosing FixYa and welcome. Make sure you check the engine compartment. Check for burnt wires, loose wires. Check for large oil spots on the engine and under the engine. If it has a lot, there may be a major oil leak. Listen for any noises the motor makes while at idle. Check to make sure all the fuses are there. Check the oil, transmission fluid, coolant fluid, and power steering fluid. Check the front and back axle. Ask to test drive it and ride it hard for a few miles. Check out the brakes, check all gears. Feel for any stalling or vibrations. Check all things such as lights, signals, air and heat, headlights, taillights, and brake lights. Check radio and wipers.
Seems that you have some problems that may or may not be related. The one of most concern is using coolant. You need to have the system pressure tested and checked for hydrocarbons in the cooling system. If you have a 4.0 engine, they are prone to developing micro-cracks in the cylinder head. (bad castings). You need to make sure that the coolant isn't escaping into the oiling system or you will loose the engine. Before testing, you can take a really good look at all hose connections, the water pump and the radiator, especially where the end tanks join with the core. Look for dried coolant stains as well as wet residue. The burning oil smell can come from minor seepage that is getting on either the exhaust manifold or exhaust pipes. Even a tiny amount can smell really bad. The leak does not have to be coming from the engine but could come from the power steering or transmission as well. (all need to be checked). As for the steering problem, without seeing it, it could be caused by worn shocks, or any steering component that is worn and loose, causing wandering. All bushings and joints need to be checked for excessive clearance or play.
does the word security stays flashing after you crank the engine? if it does vehicle has a problem with the passlock 2 system which is a factory installed anti-theft system. when faulty which is too common on those year GM models, vehicle will start and run for 2 or 3 seconds and die out. follow this procedure: 1) locate yellow 20ga. wire running out of steering column which will run along with heavier gauge wires. correct wire will be thin compared to the main ignition wires. 2) cut wire and connect an in line toggle switch and leave in on position. 3) put key in ignition and move forward and leave it that way for approximate 15 min. or until security light goes out. 4) as soon as light goes out vehicle should start. if it does not crank engine again until it starts. 5). when engine starts flip toggle switch to the off position then security light will come on. done. passlock system is bypassed. security light will stay on constant but vehicle will no longer leave you stranded.
There has been known promblem with the 03- early 05 sorento of radiator fan staying on even after engine is turn off, it is claim to be a electrical malfuction in the engine termalstat. However you may just need to check your coolant level and fill it up as there is also a promblem to the sorento's having a leaking radiator coolant resevior too. Pretty much I own a 03 sorento, and it has been nothing but promblem, but glad I got rid of it. However like I said, check your coolant level, and fill it up with 50/50 coolant to recommended level. Should be able to solve the promblem, since it seems your engine is lacking coolant and is overheating, and the fan turn on automatic even after you have shut of your car to help cool it down.
sound like the tumbler is falling out, when you open the steering column there should be a hole where a small but solid object can go in.. this release the tumbler but only when the key it turn at a certain position you will feel the pin in the hole go inwards then you can slide it out...it could be defective or just need to place back properly..hope this help..
The mechanic located the problem: A linkage in the steering column had worn out, which disabled the electronic connection from the key to the starter. Although it was much costlier to do so, I chose to purchase a new rather than a used steering column as I intend to keep the vehicle.
You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.
