My car was slowing down and jerked in and out of first gear ive been having this problem for motnths I looked on infiniti forum and seen itb12-027d and infiniti will not fix my car I almost hit someone car due to the car driving really weird ! And swerved and hit a curb instead this is ridiculous im also reporting this to the bbb as well because plenty of people are reporting this as an issue with this years transmission and engine and they arent doing anything to fix it but throw prices at their customers for the…
I have 38 pages of service regarding a starting problem. When the car is started with the AC on, it cranks but will not start. There have been 6 battery replacements, one 6 months after the car was purchased and 5 in the last 5 years. Within the last week and a half it has needed 4000 in repairs. A valve assembly, control and now an engine control module. The car was brought in dozens of times and the problem never fixed. Would be happy to provide all of the paperwork.
