2002 Jeep Grand Cherokee: check engine light

Filed May 21, 2024 · Electrical · GA

I currently own 3 of the same vehicles myself, my husband and my son. Each of the vehicles have been experiencing electrical issues. I have taken all of the vehicles at some point back to the mechanic for repairs for this issue. It was only a temporary fix. Here are examples of some of the electrical issues. The blinkers and break lights may go out and not work while we are driving and some days they work just fine. But it has now become a safety hazard because we never know when they will work and are afraid to be hit by another car from the rear. Another example is when I am driving down the street all of the sudden the windows will automatically roll down by themselves. These issues have put all of our safety at risk, especially while we are driving in high traffic areas such as Atlanta, Georgia. The problem was acessed by our auto mechanic on all three (3) vehicles. They are are 1999-2000, 2001 & 2002 Grand Cherokee one of the vehicles is a limited edition. There are no warning signs or symptoms and the check engine light is not on any of the vehicles.

Vehicle was in motion and kept stalling on highway and city streets. Another computer was installed but didn't solve the problem. The throttle position, idle air control, and map sensors were replaced. Vehicle had hard start problem and the fuel injectors and fuel filter were replaced. Started vehicle in driveway and heard popping noises and it automatically shut down. The coli pack had to be replaced. Numerous vacuum hoses have popped off during driving and had to be replaced. No error codes or check engine light would come on even though these things were happening. A year ago the oil pressure sending unit had to be replaced and has currently gone bad again. I have to put the truck in neutral and let it idle before I drive it or the transmission will jerk. I also have to let the truck stay cranked for 10-15 minutes before I can drive it because it takes that long for it to idle down. My driver seat controls will not work, and the passenger window will not stay up and the controls will not work. If you do research on the 2000-2004 jeep grand cherokee models, you will find the exact same issues from everyone who has owned these specific years and models. Chrysler knows about the constant issues, yet the 2000-2004 models are not on the buy back list. The dealerships even have a problem trying to figure out what the problem is which is why it costs so much and the problems continue to exist. Owners have had to consult with other jeep owners to work together to try to solve the problems ourselves. 2002 with only 115,000 miles on it. There would be more miles on it if problems would stop occurring with these vehicles and preventing people from driving. I put the date when it started in 2012, but constant problems are still continuing to this date and year of 2015.

I am paying for a 2002 jeep grand cherokee that I purchased used in 12-06. I have had a problem with the heater 6 months after I purchased it used, which the dealer would not repair. I called chrysler and no one returned my call until this month. I received a recall about the fan blades and took it into the shop. Prior to the shop appointment the check engine light came on, I asked the service tech to check why the heater was not working and why the check engine light was on. He called me to tell me that the recall part was on back order and that the blend motor and doors on the heater were broken and that the leak detection pump had gone out, which would prevent me from getting it inspected. He also told me that the heater plugs were melted and it needed a wiring harness replacement. The dash gets very hot which has melted the plugs but no heat is blowing into the vehicle. This could cause a fire inside the vehicle. Also the leak detection pump is an emissions problem and per federallaw has to be operating in order to pass inspection. I spoke with chrysler and asked them to repair the vehicle and they laughed at me, telling me this vehicle had been out of warranty for 4.5 years. (it was out when I purchased it.)and if it were still under warranty then they would fix it. I also asked why if the recall had been out since 2006 then why was I just now getting it, and the part was on back order which tells me that I have been driving an unsafe vehicle.he also told me that the heater being broken was not a safety issue, it is due to not having heat to defrost windows and plugs melting could cause a fire. I have checked the web and there are so many web sites that talk about these problems with the jeeps that go back to 1998- 2005. Please help me I am out of work due the medical problems and I have a very tight budget. I have contacted the n.c. Attorney generals office, consumer affairs, chrysler, nat. Assoc. Consumer affairs. At this point nothing has been done.-sharon

My 2002 jeep cherokee limited has 64,000 miles on it. The "check engine" light came on while driving. Took it to jeep dealership. Computer hook up indicated a transmission problem. I was told it needed a new "torque converter." had the torque converter replaced. When replacing the "torque converter", I was told the trans. Plate was bad and needed to be replaced. Replaced plate. Computer now says the 02 sensor is bad. Replaced 02 sensor. While getting to the 02 sensor, was told a bolt was rusted to trans. Coolant line and broke a hole in it. Had the coolant line replaced. Now the jeep stalls! Had to drive it back to the dealership with one foot on the gas, one on the brake to keep jeep running and not to cause and accident! Now I'm told my spark plugs need replacing and fuel system cleaned. Replaced spark plugs, fuel system was cleaned and replaced the idle air control motor!!! Jeep stalls when putting into reverse or drive! Why is the jeep stalling????? I've already dumped a pile of money into it and it's worse off than when I took it in the first place!

Engine light keeps coming on. Dealer, car max, stated it was a chip which cost $350 to repair. They stated it was not life threatening and will not repair it at their cost. I need to know when the light came on if the engine was in trouble or not, and I felt it should be repaired at their expense.
