Problems with 2010 Nissan Versa ENGINE AND ENGINE COOLING

When i was driving back home from class approx 11:45 am, i turned on the air conditioned and the car slowed down and started shaking. i pressed the emergency light and pulled off the road to a shoulder. i wait a few minutes turned the car and it started shaking and making the loud noise. i turned off the air conditioning system and i drove home. *tr

Muffler assembly gasket/weld failed. required replacement of muffler, gasket and tailpipe. nissan dealer stated that this is a known problem with nissan versa however they do not warranty this. *tr

Loud noise when driving. took to local mechanic next day and was told the flange broke from the muffler. *tr

Check engine light came on and turns out the evaporator had a crack in it so paid nissan $1,500 to replace it with a non-genuine evaporator part. then about six months later the check engine light came on with had ac at speed 4 when driving at any speed. told the blower motor was bad and needed replacing at the cost of $1,500 to do it. refused the work and ran blower motor on a/c at speed 3 for about a month then after that seemed to work at speed 4 as well with no check engine light coming on. i thought it was probably the speed rheostat like happened to me on a ford i had cost of item $25 and did it myself. the rheostat must have been stuck and become unstuck and i would have paid for a repair that was not needed and been scammed. *tr

While driving home from work my 2010 nissan versa began to make a rumbling sound. it has sense grown to a roar while stopped with the car in drive. i took it to the dealer where i got it and they said the rear muffler assembly had broken loose and was rubbing on the frame causing the noise and vibrations in the driver compartment. upon a brief internet search i have found that many other nissan owners have experienced the same problem. nissan claims it is due to road salt, but the only part that is rusting out is the flange leading to the rear muffler assembly. *tr

I purchased this car used from a dealership 11/3/2011, no problems whatsoever, had remainder of regular vehicle warranty left on it, no problems until the other day i thought it sounded louder than normal, so when i drove it yesterday it was still louder and i looked underneath and the muffler is loose and the exhaust sounds terrible. this is terrible for a not even three year old car with less than 30,000 miles on it!!! i called the garage where i bought it and they say it should be covered under warranty but i have to take it over for them to look at first to be sure so it better be or i will be quite upset if i have to fork out money on a car that is less than three years old on something with the exhaust! my previous car was a dodge and i had it for 7 years and never had any problems with muffler or exhaust needing replaced in 7 years!! *tr

2010 nissan versa. consumer states unintended acceleration *tgw the consumer stated he experienced engine acceleration while his foot was on the brake. the consumer stated he shifted the gear to neutral and the engine ran at an unusually high rpm for about 10 seconds before returning to its normal 1000 rpm. the second time the incident happened, the consumer was attempting to merge with the traffic from a parallel parking spot and while holding the foot brake, he felt the engine straining until he shifted the gear to neutral which allowed the engine to accelerate briefly and then it returned to normal. finally, two weeks ago, when the consumer shifted from park to drive, the engine revved up and when he shifted back to neutral the rpm's rose to over 3,000 before settling back to normal. *jb
