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.

Is Check engine light for maintenance required only or is there something wrong with the engine and I should not drive the car before I can get it to the dealer?

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.

Something is wrong if the check engine light is on. If the engine is running great then there is no great hurry to get it fixed but there is something wrong with the emissions system or the light would not be on. It is your choice to fix it or not. It may never cause any problems and it could damage the O2 sensors or the converter depending on what is wrong.
