“The car evap purge valve stays open. The car idles and dies everytime I put gas in. The purge valve was replaced less than a year of purchasing the car and it's gone bad again. The check engine light and engine malfunction warning came on then two days later the car died after I added gas and took 2 hours to start. I bought a new battery and drove it another week. It still idles after adding fuel even with the new battery. …”

“The A/C vent actuating solenoids under the dash have all failed. They don't allow the cool air to be routed properly. We have had the dealers service center check each time as they would fail, and they found replacement is needed at each visit. The actuators began failing at 6,000 miles, and continued dropping off one by one at various mileage until all three are now not functioning. My car has 11,500 miles now. The solenoids just click now constantly while driving as all three try to activate the vent doors.”

A week later it came back and stalled out on the road but was not given help. A week later error code came back took to service a few days after they said they reprogrammed the TCM and it was ready to be picked up. Drove it off the lot and it stalled on the highway less than 5 minutes after being picked up.”
