 I bought a 2007 Nissan Sentra 2.0 with a automatic CVT transmisson back in 2008... I have always keep up on my repairs, oil changes etc. The other day the service engine soon light came on so of course I took it in to be looked at. I was told by the mechanic that the engine needs to be replaced because the second cylinder has low compression which would run $3,000, What a joke! I have only had the car for a little over two years now... I was told by the mechanic that for the year the car was and how many miles it has on it (>82,000) that it should not have happened. Sentra's for the year 2007 are nothing but Lemons. I will never ever do business with Nissan again!
