Is this 2008 Altima Hybrid worth repairing?

What is your question?

My well-maintained 2008 Nissan Altima Hybrid has 113K on it and never had any issue until three weeks ago when it started shaking - running on hybrid mode was fine but idling was rough. It was towed to an AAA-approved local shop which got codes from car at no cost to me (P1195, P0AC4, P0204, P0203, P0202, P0201,P2135,P0451, and P0300) but declined to service car due to lack of information to diagnose properly. The car at this point could not even start. It was towed a Nissan dealer from whom the car was purchased. The dealer replaced brake switch to get car started and recommended a hybrid specialist to review car - their hybrid mechanic was on leave and thus not available. The car was towed to another dealer about 20 miles away, who has the hybrid computer replaced and found multiples codes: C1259, C1310, and P0A0F, P1195, P0201, 202, 203, 204. By this time the car could start but with shake so much that idling was not possible. The dealer has performed power testing to each injectors and all tested good, but coils and fuel pressure have not been tested. Hybrid battery dropped voltage during testing - a confirmed failure that I could have it replaced under warranty. At this point I have spent close to $2000 with little progress in fixing this car. With the dealer unable to provide any assurance that a fix is imminent, I have finally decided to tow the car back home to decide what to do with it.
