On march 8, 2016, while driving northbound on interstate 49 in harrisonville, mo, the engine speed raced when taken off cruise control. The jeep stayed at highway speed -- above 60mph -- and even pressing the brakes did not slow down the jeep. The only way I was able to get the jeep under control was to turn off the entire engine ignition. Only by exerting effort to overcome and compensate for the loss of power steering and power brakes was I able to coast to a safe stop off the highway. The tow operator who responded attempted to start the engine but found the same result ' runaway engine revs. The jeep was towed to dealer service department that evening. The next morning, service advisor investigated and determined that the throttle pedal was stuck down to the floor. He loosened it by manipulation. The throttle butterfly valve was found to be stuck in the open position by a shredded piece of rubber that flaked off the resonator body intake connector. Service department performed: 'rubber from intake seal stuck throttle body. Removed debris'. The technician showed me the piece of shredded rubber and gave it to me. I kept it, and the entire defective resonator body, in my possession. There may be other reports of runaway engine revs but this instance seems to be related to the design of the resonator intake pathway. Although my jeep has 246,289 miles on it, the defect was not a result of wear but seems to be result of defective design. The intake air pathway is subject to shredding rubber parts which can come loose, enter the intake air pathway and block the throttle butterfly. This seems to be an unnecessarily hazardous design.

Power steering pump has failed for the 4th time in last year. Have now learned this is a known problem by chrysler and is due to poor design that has the power steering pump driving an auxiliary cooling fan. Results in loss of power steering and extremely reduced drivable.

The cooling fan blade just broke while stopped at a light. It made the car thump I thought someone hit us but the fan blades broke the fan shrode and put dents all in the radiator and broke the fan guard. This vechile has had many of the same problems due to the electrical system. We lease the jeep and have put $$$ in it because they would not take it back as a lemon with in the 2 years. I still hear a beep coming from under the dash that jeep never found the problem or fixed it. I just had the fan relay changed because it went out. With in the first 2 years I had it in the shop for a variety of electrical problems I have all the paper work. I am afraid the jeep will catch on fire or cause an accident. I've also checked many other things that were issues with the jeep. Leaking shocks and transmission pan and emissions is now leaking. The check engine light stays on and every time I get it checked it's a different problem. I'm out of my warranty now but there have been so many different things wrong. The dealer replaced 2 of 4 leaking shocks they left the transmission pan loose when they replaced a part in the transmission. This jeep is unsafe for the road it has lost power in the past while traveling so they replaced the battery twice with in a month.

I have a 2002 jeep grand cherokee laredo, manufactured 8-2001. In november 2004, the car began to have a hard start to it. The longer the car sat, the longer it took to start it. Sometimes the cranking went on for about 10 seconds. It would do this for 2-3 weeks and then stop for 2-3 weeks and then repeat the cycle. The check engine light came on and the mesage was 341: meaning camshaft sensor malfunction. It is involved in relaying power to the engine and, if it failed, could result in loss of power while in motion. I spent $220 to have it fixed. However, the hard start still continued. I went to a jeep dealership where they told me, without a doubt, that it was the fuel pump. I asked them how in 3 minutes they could know that. They told me that there has been a really high failure rate of the fuel pump model which was installed in my car. They told me that it has been a persistent problem in grand cherokees in years 1999-2003. I asked why they had not issued a recall or investigatioin and the service assistant told me that the cost to replace these fuel pumps would be exhorbitant if done across a mass scale. However, he was more than happy to give me a $550 bill to have the fuel pump replaced. I had no choice but to pay it because, at some point, it would fail altogether resulting in an inoperable vehicle. My complaint is this: if they are aware of a serious fuel system failure that is widespread and they refuse to publicly acknowledge this fuel system failure, is there something that the federal safety agency can do? I also want to report this fuel system failure in this complaint.
