Hello. I can provide you with some information for this vehicle. Let me start with the pixels, it is a common problem for the cluster to fail in the display and some of the pixels do not light up. Some people will dissassemble the cluster and spray contact cleaner inside but at the dealer the only thing we can do is replace the cluster (not cheap). But this would not effect driveability.

Some common problems:

1. The valve cover gaskets leak due to age from brittleness. Oil will leak into the spark plug holes and contaminate the boots (coil over plug) and cause a misfire. Usually this is solved by cleaning out the plug holes, replace plugs, replace v/c gaskets. Parts about 150 and labor about 5 hours.
2. PCV plate failure. On the back of the intake manifold you have a pcv plate that fails and causes oil to enter the intake manifold and can cause misfires. Fix, remove intake manifold and replace rear cover and front seal and intake gaskets along with fouled plugs. Not sure on total cost of parts (around 200-300) labor would be about 5 hours.
3. Valley pan leak. Coolant can leak from a failed valley pan gasket. This is under the intake manifold and usually is checked during an intake reseal, as this is under the intake manifold. With the intake already off it should be another 2-3 hours for this repair since the cross over pipes for coolant must be removed.

These items are likely needed to be done anywhere from 60,000 and above. If this vehicle has a cpo warrenty then it would be covered up to 100,000 miles but only a certain number of year (this would have to be checked.)

Let me know if you can think of any questions and I will try to help.Thank you.
