Alternator/generator/regulator problems of the 2013 Nissan Altima

Instrumental gauges flickers and sometimes staying off for a second or two causing the vehicle to jerk with power lose while driving on the highway. Radio will also lunimate and die when this happens. Current vehicle has around 50k and I have replace battery, +\-battery terminal and alternator to see if this correct the problem, but this still happens!!! also all the instrumental gauge will reset its self when this happens!!!.

I purchased the car new year 2013 in 2014 I noticed a roaring noise while driving on the street at slow and high speeds. Around christmas eve I was driving when the car died out on me on the street. I had the car towed to the dealer where they did their diagnosis. They had the car for 5 days, they said they had to replace the alternator which they said had internal problems and also reprogram the system of the computer of the car at 29,326 miles which is odd to me because it was a newer car. So now its 2016 and I brought the car back in to the dealer today because it seemed as the windows would roll down slow, the car wouldnt accelerate right away when pushing down on the gas (stalling) and it would shake while driving or at a stop, and when coming to a stop it would jerk as if someone hit my rear end. They did the diagnosis and said they had to reprogram the transmission. So I now believe there is internal problems with the car which is probably going to lead to the engine or transmission to go on me. And it is a manufacturers problem because I shouldnt of had any problems like these for a 2013 now at 46,000 miles.

This is a combination of problems. Approximately around Nov. 7, 2015 the check engine light came on while at the dealer (almost one year after the last time). I have not owned my vehicle 2 years yet. I thought they had taken care of it when they told me the light shouldn't come back on. They said the code was for reprogramming the mass air system. About 2 weeks later the same light came on but this time I lost acceleration again while getting on the freeway. I had a couple of close calls on being rear-ended while having my son in the car. I had to get off immediately and drive down to the dealer which took me it seemed forever because it would barely move. I had to leave the vehicle as it was closing. The following day I was called and told that it required reprogramming of the mass air system. I had them do it but it took them 1 day to return the vehicle to me. About 2 days later the check engine light came back on again and I took it back to the same dealer. This time finding the problem wasn't as easy. They kept my vehicle for 3 days before letting me know that I needed to have the throttle chamber replaced. Really now. . . Check engine light on a total of 2 times in 1 year + 2 more time in another year, 1 alternator replaced in 1 year , 1 throttle chamber replaced in almost 2 years, leaking rear shocks in 1 year and Nissan does nothing to replace my vehicle which is a constant safety hazard for me and my family.
