I am assuming you are talking about the 'check engine' or 'service engine' light, right? Well, they can cut the light out by clearing your car's computer memory, but it came on for a reason in the first place. So, if they didn't fix the problem, guess what? You will get the light on again. I think they know this too. I would say the dealer would have to be pretty brave to NOT fix whatever the problem was. By retrieiving the trouble code on your vehicle's on board computer, they can easily go right to the system on your vehicle that is experiencing a problem. It's not like it is that hard to trouble shoot a vehicle with an on board computer since they have specially trained mechanics for your particular vehicle make. I would say you could trust their work if the light didn't come on after driving away and they could give you a detailed description of what the problem was. But as a consumer, remember you do have the right to ask and if they say they are going to or did replace a part, make sure you let them know you are going to want to see the old part or have them point out the new part to you when you pick up your vehicle.
Yes
dealer has them for 800 and something. Lighting control module
You check engine light is signaling to you that there is something wrong with you car. You should have your car looked at by a professional.
The check engine light means that there is something not going right with the engine, but it may not be serious. Take it to Auto Zone or a small shop with the capability to read out the ODBII codes rather than go to the dealer. They'll plug it in and be able to tell you what error triggered the check engine light. I've had my light come on twice, neither time was it a serious problem. The first time was due to bad fuel, the second a minor electrical short in the air intake temperature sensor.
Drive it to the mechanic. You have something wrong and that is what the car is telling you. Oil, water, something is not right.
it resets every time you turn your car on. i have a 01 eclipse and the dealer told me that.
It depends...Some faults turn on the Check engine light and some dont. You will need to get the car scanned to be certain that there are no fault codes.
the engine light stays on. Hyundai dealer wants 241 plus to install and fix. Does using car with engine light on do damage?
Yeah, it can. If something is wrong with your emmision control system, your car can still fail emmisons, but the check engine light doesn't have to be on.
engine has defaulted to limp home mode... (engine fail safe mode) get to a dealer or mechanic as soon as possible
The best thing to do is go to your dealer or ask a mechanic. I ride a motorcycle and do not own a car so I can't help you much with this.
meaning something's wrong with your engine, go to your car shop and have it diagnosed.
