First it started out in July 2007,ac wasn't blowing like it should be replaced control heads. Then my trac control light came on and park brake light was on checked and advised replaced speed sensor. Then check engine light came on found upstream bank 2 02 sensor reading out of spec. Replaced 02 sensor and clear codes. That cost me$1285. 51. Which I replaced sensor,spark plugs,coil then in Jan 2008 my transmission shift hard into reverse checked and advised found faults in solenoid,valve body,trans filter,repaired clear codes,ok. Replaced drive belt and pulley. That bill was 1318. 72. Well then in 08/2008 same thing transmission shifts rough concern cylinder misfire. Check engine light back on. Thank god had a recall from Ford on that. Found contamination in both sides replaced affected coils,plugs,and cover which they only replaced 4 of the 8 coils. That would have been 593. 18. Then on 08/2008 coolant leak just 3 days after getting it out of the shop had to replace leaking thermostat connector. Haven't had any problems running hot until they worked on it 08/11/2008. The power window was inoperative. The dealer replaced the regulator/motor. Updated 10/22/08.

The car was running out of coolant very fast. Then the check engine light kept coming on. You can smell fumes coming through the heating vents. Took it to the dealer & oil is mixing with the spark plugs & with a water midst. Bought the car in 09/2005 with 39,000 miles. Engine needs replaced at 67,000 miles. Haven't been able to drive the car in 5 months. Estimate cost to replace with a used engine is $3,794. 60. The dealer sold this car in this condition. They need to recall all the Lincoln Ls.
