I was pulling into my work parking lot when the transmission suddenly stopped engaging. I had to push the vehicle into a space. Mechanic confirms I need a knew transmission. I discovered that there is a known issue with the transmission of this vehicle, I called Mercury/Ford and had to reference the case # myself for them to find it. The customer service representative confirmed that my vehicle met the specific requirements for the customer satisfaction program (csp: 09b10) - all the way down to a specific manufacturing plant up to a specific month and date but because they stopped honoring those in 2011 I am not eligible. I am the 2nd owner of this vehicle and had no way to know this was a hazard, not was the dealer aware as Ford/Mercury had apparently removed the csp number from the files once it expired. This is proven by the fact that Ford/Mercury's own representative didnt' see it linked to my vehicle, I had to mention it specifically and then she confirmed that it did apply to my vehicle and was unassociated with it at expiration. As such, there is no way to know whether this was addressed or even an issue. My concern is had it been 20 minutes earlier that the transmission went out, my 3 1/2 year old daughter and I would have been going highway speeds on a 6 lane highway!! very dangerous! Ford/Mercury should have to recall this item, which is clearly a known manufacturing issue. I should not have to pay $2000 to fix something that they did incorrectly from the first and poses a great safety risk!.

My 2008 Mariner automatic transmission will not shift properly when cold (winter) or too hot. This also affects the idle when stopped. When vehicle tries to shift up, it will only shift if I let off the gas, then the transmission slams into the higher gear. The vehicle will hesitate when trying to use passing gear to pass other vehicles. This has led to some close calls/near misses when trying to over-take vehicles. Ford says they know there is a problem with this make/model but have not issued a recall. Ford says they can fix it with my money.
Hybrid version of 2008 Mercury Mariner SUV intermittent illumination of (2) dashboard warning lamps: multiple appearances of "yellow wrench" symbol @ l/edge instrument panel - manual vague, Ford svc writer says lamp indicates fault detected in electronically-controlled cvt (continuously variable transmission); clears with shut-down/restart. Dealership unable to schedule prompt diagnostic, claiming only one tech/tool. Has not recurred in ~ 45 days. Today (12-24-08), the red triangle warning @ right edge of inst panel came on after cold-start & driving <100 feet - accompanied by info text warning to `make immediate safe stop'.
