“Around june 2008 my Mini cooper s 2005 began exhibiting what appeared to be a failure to maintain consistent speed while driving at a constant RPM. I experienced slow, or sluggish acceleration while driving and the engine light would come on sporadically. I took my Mini, which was still under warranty in for service to bmw/Mini of san antonio and was reassured that I was experiencing normal shifting mechanics. They were also unable to detect why the engine light was coming on. …”
NHTSA complaint #10563887, filed 2014-02, 48,022 miles“When my Mini Cooper S Convertible only had around 85,000 mile on speedometer my transmission would suddenly have difficulty going from 3rd to 4th gear and stall while going down the road and I have almost been rear ended by cars behind me not expecting me to stall.

I think this should be addressed as a recall before some one is killed.”
