This Lincoln Mkt has given continual problems with fuel issues, engine problems, check engine light constantly coming on and taking it back and forth to the dealer and they cant even figure out the issue as to why the check engine light keeps coming on. The vehicle has fumes coming from the pipes, it jerks and threatens to cut off and with all the repairs done and complaints sent to the Lincoln Corp, there is still no resolve. This is our family car, but we never know when it is going to shut off or start smoking or when the check engine light will come on. This makes the vehicle unsafe to drive and it seems to be unrepairable. Especially since each time we get it back from the dealership, the light comes back on. These problems occur with the vehicle in motion. I don't know when it is going to function properly or not and most times, I have my children with me. It is really scary.

Very strong exhaust fumes in cabin under heavy acceleration. Smells like sulfur or rotten eggs. Dealership has stated there is no solution. This appears to be the same issue that has affected other Lincoln & Ford models (such as the Ford Explorer).

This vehicle was modified by small volume manufacturer baf technologies (now westport) with an epa-approved CNG conversion package. The fuel filler receptacle, however, was not securely mounted to the frame. It was merely mounted on a plastic disc and glued to a plastic interior body panel. That glued mounting has now failed within the 'bumper to bumper' warranty period, but westport/baf has refused to repair it under warranty. Their los angeles warranty service provider has also refused to perform this repair even if I pay for it. The original mounting method is extremely weak and would result in serious or catastrophic damage (e.g. gas leak, fire, explosion) if the user were to 'drive off' with the dispenser hose attached. All of these vehicles need to be retrofitted to meet nfpa requirements for mobile CNG systems, including the ability to survive a 'drive-off' without serious or catastrophic damage. See nfpa section 52 6.9.2 "the fueling connection receptacle shall be mounted to withstand the breakaway force specified in 7.11.6.2. (150 pounds in any direction the vehicle can move)" in addition, I believe this mounting violates nfpa 6.9.3 (receptacle not installed in accordance with manufacturer's recommendations) and 6.9.4 (insufficient clearance to prevent interference with operation of the fueling nozzle). This failure occurred when the vehicle was being refueled. The only damage in this case was to the receptacle mounting. The mounting was apparently not even strong enough to withstand the forces of connecting and disconnecting the fueling hose and nozzle during normal fueling operations.

The panoramic roofs on the Lincoln Mkt blow out for no reason. We have 14 of these Mkt's in our fleet we have had close to 10 of the glass roofs shatter. We are very concerned that glass could fall into a drivers eyes as well as our passengers. Also when they do blow out a good size chunk of the roof blows out and anyone behind us could be in grave danger especially someone on a motorcycle. The design of these roofs is flawed and either these roofs should not be allowed or they should be design with a type of glass or plastic product that wont shatter. Lincoln has helped in some of the incidences with the cost but are now telling us a definitive no! cost to replace a glass roof runs about $1500
