Fuel/propulsion: the vehicle will run after starting for 5-8 minutes then the RPM's drop to 300 and acts like its going to stall; then.the car begins bucking, jerking, and revving up. There are loud clunks from the engine compartments. I have replaced the cam & crankshaft sensors, throttle position sensor and no change yet. Next I am going to replace the fuel pump, filter, the fuel line between them. Air bags: the airbag light goes on and off. The only fix I have read about is the clock spring...talk about money pit!! Brakes: yes. Front brakes have locked up and caused issues. Discs and calipers have been replaced. Also, driver's side break light is not functional. The tail lights work, but once the brake is depressed, the right and top lights work, but the driver's light is off. And just for fun...I've had to replace both side mirrors due to internal springs failing as well as both front window regulators and motors. When I went to autozone to get parts, they correct window regulator was under the 2000 model year; 1999 did not fit. We are gonna get rid of this jeep...chrysler needs a lesson in taking responsibility. We'll buy a toyota.

Auto had 40000+ miles when I bought it from my brother. I had it only a few months when it stalled on the interstate. It would not start until I sat for a little while. I am capable of overcoming auto trouble so I didn't think much about this incident due to the fact that I have been a mechanic for many years now. Then it began to stall in heavy traffic and sometimes would start again and other times after waiting several minutes. I replaced the crank sensor, in-tank fuel pump and filter. It ran okay for a while but began to hard start and stall again about 2 mos. Ago. Then 2 days ago it stalled something like 25 times coming home from the hospital. Since then I have been on the internet reading the blogs about this problem and if everyone that has this issue would email you, your computers would shut down. It is unbelievable that the manufacturer is just replacing the expensive parts at random, taking the money and not fixing the problem. These people, myself included, are begging for a solution to a problem with a very nice automobile made in america by skilled top dollar union labor. It is getting close to scam epidemic. My car is sitting in my garage not fixed because there are about ten different things in the electrical and fuel system that can cause these symptoms. I am a disabled veteran and cannot afford to go down that eliminating process. My doctor doesn't do me that way and I won't allow the manufacturer to do it either.

I own a 1999 jeep grand cherokee laredo and the fuel pump went bad and I could smell smoke, like and electrical problem. The mechanic said it was the fuel pump and I authorized him to repair. I then looked online to find that the fuel pump which my jeep had was a recalled aftermarket fuel pump from airtex. I called airtex and they gave me the run around asked me all sorts of questions , are you sure this is the right one and did I have the part to ship back to them. I called the mechanic and he already replaced it with a new airtex fuel pump and threw the other away. I have the receipt but cannot send the old fuel pump back. They refuse to reimburse me for this recalled product even when my mechanic wrote down the old make and model number of the old recalled fuel pump. This is wrong and unfair. $500 I am out .

Just finished repairing daughter in laws vehicle. A 1999 jeep grand cherokee. She complained of extreme gas fumes inside her vehicle. With a 1 year old and a 3 year old being transported in vehicle immediate attention was required. This is what I found. The ordinary steel fuel pressure connecter (disconnect) at top of fuel pump was completely rusted through and squirting a stream of gas, via rusted out pinhole,under pressure, all over top of fuel tank and surrounding area. Thank god no ignition resulted,would have been catastrophic. Connecter should have been either stainless steel or at least plastic at such an important location. Plain steel should never be used at such an important location. As there are many many thousands of this year vehicles out there this is a ticking time bomb. Even my vintage 1991 ford pickup used stainless steel at gas tank fittings. Vehicle is second car and was purchased a few years ago. Body is remarkable rust free for a salty n.y. S, vehicle. And is in good condition other than dangerous gas tank issue. It is only a question of time before a dangerous fire will occur in someone's vehicle and hopefully no one will die.this issue needs ,and must,be addressed . Have attached photo of rusted disconnect and have retained the rusted connector. Hope I did not waste my time with this important information and will expect a timely reply[xxx] p.s. Connecter was so severely rusted and frozen to fuel pump outlet it had to slotted with a cutoff wheel to remove- a very hazardous procedure.(can not attach photo on this site) information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

99 jeep grand cherokee with engine problems customer states that the RPM's would immediately go up to the 200 or sometimes higher as soon as he starts up the car and also accelerate when the brakes are applied**cc the consumer stated various parts were replaced, however the problem returned. The consumers wife was driving, when all of a sudden the vehicle started to accelerate on its own, she applied the brakes as hard as she could, however the vehicle continued to proceed in a forward motion. The only solution was to place the vehicle into park. After placing the vehicle in park, the consumers wife placed it in drive again and immediately it started to accelerate uncontrollably. Applying the brakes with full force did not solve the problem. When aaa arrived and started the vehicle, nothing happened.

Engine dies at any speed without warning and without illuminating the check engine light. No error codes are stored. It acts as if someone just turned the ignition key to off and all of the gauges on the instrument panel are zeroed to the left but everything else electrical still works, starter, power windows, radio, horn, lights, power-seats, etc. Etc.. This tends to happen more often on warm days, over 88 degrees f and seems to be a shutdown of the PCM which controls the fuel pump, fuel injectors and the ignition system. When the PCM shuts down, it drops output to PCM's computer bus called the ccd. I changed the parts that the dealer wanted to change like the fuel pump, crank and cam sensors and cleaned a host of other sensors but the problem remains. The problem is with the PCM. The dealer denies coverage because the mileage has just crept over 80,000 miles although I began discussing it with them and buying parts from them back on march 5, 2005. This is an extremely dangerous condition that warrants the PCM, p/n rl044427ac through aj, on the 1999 jeep grand cherokee be recalled.
