2012 Nissan Sentra started malfunctioning with battery replacement on March 25, 2015 at hanlees Nissan in davis, CA, where I had purchased the vehicle in sept 2013 and where I had most service performed while I owned the vehicle. I commuted 1. 5 hours each way for a new job in rohnert park and I was becoming ill. Unable to locate housing in the area I was unable to keep the job for more than 2 weeks. I suspect foul play with the davis service department. Car started having a loud clicking sound at just less than 30mph. Davis serviced car for two more years. They cannot provide a duplicate sales contract saying it is lost. Davis referred me to kim at fairfield Nissan and she told me it is missing. This difficulty should not exist. I asked lienholder crb auto/mechanics bank to provide a copy and I have yet to receive. I made multiple attempts to have my car assessed at Nissan davis, vacaville, north bay Nissan in petaluma (replaced catalytic converter 7-31-17 60, 000 miles) problem not corrected. Vehicle now developed extremely poor gas mileage. I continued to get sicker. I had been illegally evicted from my rental home at 7172 yolano road, dixon, CA 95620 June 3, 2017 with harsh bullying against law in concert with the solano county sheriff's (ongoing investigation) I had had the vehicle towed to davis prior to leaving that address. I told them I got really ill when driving the car. They refused diagnostic work and recommended cleaning detail of car at my expense. Did poor job and had to repeat. Once homeless, I was in the car, relocated to marin county and continued to deteriorate in health. (er visits to document). Mileage had been 35-40 mpg decreased to15-20 mpg. Had vehicle towed to sf Nissan on 10-3-17 and they reset all codes, could find nothing wrong. Car impounded in dt sf on 10-6-17; robbed of impound $500 cash and belongings on 10-10-17. Please help.
Upon accelerating the car makes a awful clunking noise that is not only heard but felt on the floor under your feet this happens often. The dealer stated this was normal. I pressed the gas pedal while switching lanes and the engine revved up, but the car did not move. It took the transmission several seconds to catch up to the engine.
