Cruise Control problems of the 2002 Volkswagen Beetle

Bought this vw Beetle used. Had terrible smell, like burnt crayons. Cleaned it intensely, inside and outside. Thorough detail job. Still smells, causing headache. Air bag light and buzzer stayed on even after latching seat belt. Cruise control works erratically, lunging forward suddenly, then chugs, then lunges forward quickly again. Speed works consistently when cruise control is not engaged. Very unsafe with cruise control in use. Lighting issues. Interior lights would not work, unable to see interior gauges in the dark. Turn signals blinking erratically, and not in sync. Took vehicle in for repairs at an authorized vw dealer, paid $1,300. 00. Still not working properly. Took it back in 4 days later because drivers side window almost fell out while driving, and interior lighting issues still did not work. Was charged another $600. 00. Vehicle will not engage into drive position easily, and sometimes not at all unless the steering wheel is jerked on. Dealer said sensors were the problem, and that I will need to bring it back again to have the cruise control fixed at a cost of $250. 00. I am scared to drive this vehicle now. There should be some recalls on the smell issue, and the air bag/seat belt issue. Also cruise control issue, because I have been told it is associated with the electrical problems.

The epc light comes on the dash. I was told this is due to a brake light switch that will go out. This causes cruise control to go out, brake lights to not work, and difficulty getting your gearshift out of park or neutral.
