| Our 2011 jeep grand cherokee has exhibited multiple instances of sudden unintended acceleration (sua). it has occurred to my wife, one of our sons who is and aerospace engineer and myself on different days at different speeds and locations. i personally have experienced it on two occasions, one of which caused a minor accident as i was backing out of a parking space, with my foot on the brake put the car in drive and it lunged forward of its own accord, there were two other people in the car and a witness outside the car who reported it just lunged and the brake lights were still on. chrysler inspected the car, found nothing and has closed the case. i called chrysler and asked that we discuss the issue they said they found noting, fixed noting and thus the case is closed. so they are calling three people bold face liars and my concern is they did not find anything so the cause of the problem still exists and can happen again and my wife is at risk every time she gets in the car. there are over 1,000 complaints on various forums about sua instances on jeep cherokees, channel 7 news even did a segment on it a few years back. can you please help at all on this issue? thank you. *tr | |||

| 2011, 2012 chrysler vehicles with the pentastar v6 3.6 liter engine are rated to tow 5000 lbs unrestricted with the tow package installed. there is a design defect in the cooling system in that it cannot cool the engine when towing about 3500 lbs uphill. the tow vehicle starts uphill at the highway speeds of 65mph in the passing lanes with enough power to continue and suddenly without any warning, lights, etc., the tow vehicle looses power and abruptly slows to a maximum speed of about 27mph. with all other vehicles on the road trying to get by and not slow down, this creates an extreemly dangerous situation of attempting to cross 3 lanes or more to get off the road while tractor trailures have to slam on the brakes and hopefully screech to an almost stopped position to avoid killing the families in the tow vehicles. chrysler has confirmed the problem but has refused to do anything about it and has insisted that the vehicles are working the way they were designed but are obviously not working within the advertized specifications. chrysler does not want to change the advertized specs due to the fact that it might cost them money, even though many peoples lives are at risk. chrysler could easily perform a recall and fix the problem, saving lives, but there would be a small monetary cost to chrysler. | |||

| Transmission shifted into 4 wheel drive (4wd) low, suddenly, accompanied by a clunk and change in vehicle speed from downshifting. lights came one in the dash indicating loss of traction control and 4wd service needed. this event continued to happen sporadically while driving until we made it back to the dealership. since downshifting into 4wd low occurred while driving at normal roadway operating speeds (approximately 20-40 mph) it certainly felt like a safety issue, compounded by the fact that traction control was lost as a result. once back at the dealership, the service department found that the transfer case had an internal failure. the vehicle was in the shop for about 3 weeks and while the transfer case was replaced under warranty. due to this negative experience with the vehicle we no longer felt safe driving it, and ended up trading it in for another vehicle just a few weeks after getting it back from the shop. | |||

| Driving down the street when white steam like smoke comes from under the hood. the smoke becomes dense and there is a smell of hot transmission fluid. the vehicle begins to power off and upon exiting the vehicle there is a strong smell of transmission fluid and a large pool of fluid discharged under the vehicle. the car was towed and returned to the dealership. the dealers technician reported, technician performed visual inspections and clean off of fluid found the transmission cooler lines at the radiator had disconnected due to not be improper connection issues reinstalled both transmission cooler lines and clamped lines, tested pressure on both lines. filled system and test drove and cleaned (due to massive spray from lines coming loose), pulled vehicle back into shop and rechecked fluid level and cleaned area (repeated this process several times to bring fluid level to proper level) finish cleaning engine area and verified. parts:6 fluid-atf +4. my issue is that i had just exited a high speed, 65mph, highway and if this failure had happened on something less then a slow secondary road with no traffic, there could have been a significant accident or potential injury. | |||

| When driving between 0 to 5 miles per hour i pressed on the accelerator pedal while the auto was either on level surface or at the beginning of a small incline the auto did not move forward. then i shifted the auto into reverse and stepped on the accelerator pedal and the auto did not move backwards. i then turned the auto off with the auto shifted into park. then i restarted the auto and shifted into drive and pressed on the accelerator pedal and the auto did move forward. the same day i brought the auto into the jeep dealer whom i leased the auto from just five days earlier, to identify and fix the defect causing the aforementioned problem. on monday 11/8/10 the dealer informed me the vehicle is operating as designed and they found nothing wrong with it, and they returned the vehicle to me. i am concerned that the defect which caused the aforementioned problem on 11/6/10 could cause reoccurrence(s) of the aforementioned problem (even at higher speeds) | |||
