2012 NISSAN VERSA with 115800. miles

The transmission has had ongoing issues since manufactured. Nissan has known of the issue but has made patch work of the issue instead of replacing the transmission. Since the recall deadline was may 9,2020 they are recommending the transmission to be replaced but unwilling to repair it under the recall at my cost. In good faith of the company, they knew of the issue and should cover the majority of the cost and i was willingly to pay a portion however they are not willing to help. I was unable to take the car to their shop before the deadline due to the government lockdown. The code that the always comes up on when the check engine light comes on is P0486. The have replace the valve body and reprogrammed several times but the check engine light come on and the reprogram it and did not want to replace the transmission until after their recall was expired. I have barely put 4300 miles on it since the patch job they did. They said that this patch would correct the issue and the same issue should not happen again.This is my daily driver and the light would stay on but went off prior to my first visit in june but on three days later. The dealership couldn?T get me in until june 10.

2007 JEEP WRANGLER with 85000.0 miles

Strong smell of gas in the garage after shutting Jeep off for past 3-4 years. Fuel spit issue resolved with warranty 12/2013. Gas smell after shutting Jeep off continued. 09/2014 dealership pulled code P0456, "vent tube at tank broken." paid to have dealership order and install a new tank only to find the "new tank has crack at rollover valve," had to order a second replacement fuel tank, installed with no problems noted. Heavy smell of residual fuel in the garage continued to persist to the point where we have to leave the garage open to vent the fumes for fear of ignition. Could not visually identify any fuel leak. All the while have had intermittent check engine lights coming off and on pointing to emissions and fuel system. Another trip to the dealership 07/2015, pulled code P0406, stated "couldn't find anything at this time." heavy gas smell continues to get worse. 07/2016 took Jeep to mechanic, pulled codes P0456 and P0486, found the fuel tank vent tube was cracked again, needed a new fuel tank and egr valve. Back to the dealership. Tank is out of warranty, have to replace the 22 month old fuel tank again. The fuel system has had consistent problems from inception. The heavy gas odor and cracked fuel tanks pose a serious life safety and environmental concern. It is only a matter of time before a vehicle and/or a residence catches fire. The continuous exposure to gas vapors alone is serious concern due to the carcinogenic nature of fuel and its vapors. After researching this issue in various Jeep forums online, this does not seem to be a singular event and is actually quite common. Many Jeep enthusiasts are diy'ers and are modifying/jury rigging the vent tube themselves instead of paying for a replacement tank, which means there are a lot of Jeeps causing heightened emissions and pose further safety concerns that are going unreported and that you are unaware of.
