1999 Jeep Grand Cherokee: engine knocking or ticking

Filed Aug 11, 2016 · Engine, Visibility · 156,000 miles · CA

I have owned 8 jeeps and now have a beautiful dealershipl maintained grand cherokee limited 4.7l in my driveway with a bad engine. At 100k a rod bearing went bad and after that was fixed by me with great expense it now sits in the driveway with low compression and will not start. I have searched and found hundreds of ads with blown engines just in my area of southern california. There seems to be some common design flaws in the 4.7l that chrysler corporation has been hiding and we the people have been paying for it. Dealers deny any problems but yet on any given day the classifies are full of them. I love the vehicle in general that's why I have owned so many but feel taken advantage of and can't afford to drive a chrysler piece of crap anymore. I was stranded on the highway like many of us were and put in a perilous situations because of it with family in the car plus I was on crutches . Chrysler should being offering assistance because of their faults. I also just got done repairing the faulty blend door because of the lack of visibility.

Excessive engine knocking with power loss and abnormal driving capabilites. Sounds like bad internals. Suspension causes "death wobble" at cruising speeds. Engine happens anytime engine is running producing large quantities of smoke from tailpipe.

Out of know where the engine just started knocking, and the smell of gas and the steering wheel started acting out of control. I had to park it and get another car. But I still have it because I really like my jeep!

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).

I went into jim brown auto sales on friday 1/29/2011 to purchase a vehicle. The sale representative [xxx] advised me that of the list of cars I brought in the 1999 jeep grand cherokee was the best one. While processing paper work. I asked [xxx] for a copy of the vehicle report. He acknowledge but never provided the documentation. I drove the vehicle to an near by auto shop (m-l) to have the vehicle looked at. On the way to m-l I heard the car knocking. I was advised that there are numerous issues with the vehicle. Being the front drive shaft, transmission, and transfer case. I advised the seller once I found out. I was told by the person who picked up the phone that I will be called back regarding this matter. No one called. On wednesday, february 1, I drove to brakeway to have the brakes looked at because the lights came on. Brakeway advised the same issues as m-l. I took the vehicle back to jim brown auto and requested the truck be looked at. They accepted the truck but refused to look at the issues that were pointed out. I just need some justice regarding this vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Crankshaft counter balance weights scraping against internal engine block due to main crankshaft thrust bearing wearing out at 115,000 miles due to bad oem part. All other engine parts are excellent! This wear causes an internal ticking sound that steadily gets louder as wear continues. Replacement of the thrust bearing requires engine removal, engine disassembly and is not practical. After $900 for diagnostic work, mechanic says put it back together and drive it until it stops, then replace the entire engine.............or replace it now........the part will fail and be terminal to the engine.

I have taken my jeep cherokee numerous times to have an engine knock...a whining noise and a banging noise checked out. Everyone except the service people can hear these noises. I was told by a mechanic that used to work for chrysler that they know there is a problem with the engine and the transmission and that they are not acknowledging it. I watched the today show on august 4th and heard about the problems that exist with the transmission on the jeep cherokee and became concerned. I have repeatedly voiced these concerns to the service department and also spoke to a chrysler rep directly in a 3 way conversation. I was told that they would have my complaint on file. The whining and banging noise has now turned into a grinding noise that I am afraid is effecting the power train to the point that it will fail. The service dept. Has replaced (unnecessarily) the shocks,the battery, and the drive shaft,saying that this will remedy the problem. It has not>

The motor has a metallic type knocking or tapping noise that increases in rapidity as the RPM increases until it becomes a high pitched screaming type sound. The dealer refuses to accept this as a problem since other 1999 6 cylinder jeeps do it also. However my 1996 jeep with the same engine didnot make these noises.
