Probably not. GM should have notified you of the problem, but after 10 years, you are probably stuck. I had the same problem with a past Onstar upgrade offer that expired before I found out about it - it appears that unless the problem can cause injury, they are not obligated by law to issue a recall. The Alldatadiy.com website usually lists any technical notices for cars, and in future you may wish to look at what they have for this vehicle to ensure all recalls have been taken care of.

You need a new gauge panel. Very common problem with these cars. There are people that can repair them like new.

A lot depends on how and where you are diving the car, and what you can do about repairs. I have found that, on average, cars at 10+ years old start requiring replacement of parts that are subject to wear or age, such as what you are experiencing. If you want to keep driving it, you should expect to be servicing sensors and other engine parts, brakes, suspension parts, fuel system parts, etc. to keep it running properly. There are a lot of opinions out there (including mine), but I think there are two schools of thought on this. Depreciation is a major factor, and at 10 years for a car that needs repairs, it really isn't worth much. So, if you can and have the time and tools to do most of the work yourself, this is the way to go as the total cost over life (including original purchase price) is a lot less than the cost of a much newer replacement vehicle. However, if you cannot do any work yourself, repair labor costs will eat your lunch, and you are better off getting it to an acceptable working condition and then unloading it, going for a much newer low mileage vehicle. I would suggest if you go this route, be sure to get a decent power train warranty and that the new one is no older than three years.

These bulbs are replaceable, however, the cluster must be removed to do so. It is usually held in place with four screws and the trim/bezel may have to be removed to access these screws. Once removed, the cluster will pull out and the bulb can be changed

Check that there is not a blown fuse to the wiper motors, and check the cabling further to see why there is no wiper activity. The circuit for the wind shield washer pump is separate.

Impalas have three panels. One under the hood, one the drivers side and one on the passenger side, (open the doors and pull the panels at each side of the dash). All the panels are marked for the fuses and relays.

Jack up 1 tire at a time and see if a wheel is stuck. Make sure you do this on a level surface and you block the back wheels when you lift either of the front tires. I am guessing but a calliper is prob jammed but could be a bad wheel bearing collapsed or something else binding in the front drive train.

Your line runs from the reservoir in the fender well, up through the hose around the strut plate on top, through the bezel to the wipers. If you have no leaks, Replace the washer motor. If you fill it and it leaks, fix the leaks. To access the reservoir. Remove the tire and inner fender well on the passenger side.

Code 300 is a generic code for a random miss, no specific cylinder. Code 301 would be for cylinder one, 302 is cylinder two, and so on. Four digit codes are brand specific, and I don't find anything for GM but that's not to say the code is not used for GM cars. If it is a fuel trim problem, it could be caused by the miss. There is a good chance the main problem is one of the injectors rather than ignition.
