Radio/tape Cd Player problems of the 2002 Dodge Intrepid

Ignition switch failure. After turning off car, switch slips into accessory position and drains battery. Car does not start when I return to the car to go somewhere. I need to pay for a jump or new battery, or tow to my mechanic. Then I have to keep replacing the ignition switch. The original ignition switch lasted until 2011. The after market ignition switches fail within about a year. Sometimes within a few months. Since Jan. 2011, I have had to replace the ignition switch on 1/10/11 cost $147. 50, 2/16/2012, cost $220. 39, alternator assembly, cost $588. 28 (mechanic thought it couldn't be the switch again), starter assembly again 2/21/14, cost $384. 23; recommended I replace the radio since the electrical system shorted out 3/14/2014, cost $45:ignition switch again on 8/01/14, cost $110. 56. Also this car keeps having the left rear taillights fail. They tell me this is all part of the electrical system short which they guess is causing all of the above problems. But all these problems didn't exist until I made the first replacement of the original ignition switch. I believe that the aftermarket was full of faulty gm ignition switches and there was no way for my mechanic to tell if we were getting bad gm designed switches. Luckily for me and my passengers my car didn't fail while I was driving. It always happened when the car was parked. But having 95 year old passengers, on hot florida days, get into a car that won't start, cannot be cooled down, cannot even roll down the windows since they are electric , these conditions could have killed my elderly fragile passengers. There should be some way of insuring that all those bad switches are removed from the aftermarket.

Consumer noticed that vehicle lost radio power, power locks, and interior lights. Dealership serviced vehicle, and technician determined that headlight switch needed to be replaced.

There is a strange unknown beep sound that comes from the inside drivers side of vehicle. This is not the door a jar chime. I am not sure if it has to do with the cd player or stereo being on. Several passengers have noticed this intermittent beeping that seems to occur for no specific given reason or time. The beep is always the same volume, tone and sounds like some type of BMW or Honda anti-theft device that beeps instead of chirping a siren or horn. This just occurs sometimes for no specific reason and I have not been able to invoke it. Several passengers thought it was an anti-theft device. The Intrepid has keyless entry but no anti-theft device and has stock base cd player. I have tried everything to try and invoke it, locking, unlocking, opening and closing the doors. Also a seperate issue, when driving with cruise control and accelerating with the cruise button an interference type, light clicking noise can be heard in the drivers side speaker during transmission kickdown and acceleration using the cruise control accel button. The speed of the noise increases with the speed of the vehicle and begins to fade until you cannot hear it. This is intermittent and does not always occur. Passengers have also heard and questioned this as well. These issues are a distraction and I would like to know why they occur. Selling dealer cannot duplicate.
