In the last month we've had multiple sensor failures on our 2003 Jeep LIberty. So far they have replaced or performed the following services:
Throttle Position Sensor
Cam Shaft Sensor
Crank Sensor
Multi Function Sensor
Fuel Injection Cleaning
Throttle Bottle Service
What is happening to our Jeep? Will it contiue? How many more sensors are there? Is it time to get a new car? Our 11 year old Saturn is currently more reliable than the Jeep.

SOURCE: I was just told I need crank and cam sensor ,
Hello there, Sounds a bit pricey to me. As far as the fuel injection and throttle body services these are done for maintenance reasons, I am sure it is something you can do when it fits your budget.
Now as far as the cam and crank sensor if there is a problem with one of these sensors you will have a drivablity problem such as hard starting and a lot of times shutting down after the car warms up.
If your not experiencing any driveability problems with your vehicle I would suggest having the computer resset and see if your light comes back on or if they were false codes.
Good luck and I hope this helps you, Allen
