Filed May 15, 2018 · Engine · 190,000 miles · VA

After driving approximately 30 miles on the interstate I stopped and went into a store. When I came back out in 5-10 minutes and attempted to started it, the engine felt as though it were "jumping". Had it towed to the dealer. They said it had dropped a valve seat. Chrysler determined that it happened because it had been overheated. However there were absolutely no overheat codes in the computer. The gauges have never read hot. It was not low on coolant. They stated that there were no leaks. It was never hot.

A week ago before incident, power steering pump fluid level showed normal. About 63 miles later, the vehicle got steering wheel become stiff and near impossible to turn either direction. Then engine overheated very quickly and then engine stalled without warning. There was no "engine check" warning on instrument. A/c stopped working just before overheated. Found antifreeze solution leaked out into street surface. Next day, the vehicle had to tow and delivered to jeep dealer sane date as incident. They informed me about problem was failed power steering pump assembly because of fluid leaked. That same pump also drive twin cooling fans instead of electric motor. I learned chrysler knew about this incident and then redesigned later model quietly. I also found many incident from online forum as so many owners have same kind of experience. There was no recall from chrysler because it related to near lock-up steering wheel. If I drive over 65 MPH on I-95 would lead lost control with steering wheel. No computer system detect this situation because there was no sensor to watch for fluid level in the steering pump. No warning at all until incident. Paid 100 dollars for lifetime service contract through chrysler. This situation, chrysler should recall to prevent lost steering control and avoid engine overheating and possible engine damage. They avoid to use electric cooling fans to save money. Use hydraulic from power steering pump was not smart way included lack of sensor(s) for computer for early warning. This kind of incident, must recall to correct the situation as I asked them if new power steering pump had been updated. No answer this question and learned the pump made by toyota and there are many owners as mentioned above that face unexpectedly failures. This incident consider as dangerous and harmful to owner/passenger(s) safety.

Originally having issues slowing down going around corners and up a steep incline. Felt like vehicle was staying in higher gear, you could down shift it manually. At that time there were no codes present in the system. Then last year in august 2011 we did a cross county trip (7000 miles) vehicle would stall at both low speed and high speeds, not every day. Sometimes vehicle would restart itself and others the key had to be removed and reinserted, but most times not. The weather did not seem to be a factor. Upon return vehicle had approx 45,000 miles, codes retreived from vehicle were multiple. Active codes: b2105, c121c pending code: p0524 stored codes p0129, p0688, p0884. At 35,000 miles new oem spark plugs and water pump (due to coolant leak) with new antifreeze. Vehicle is serviced regularly every 3,000 miles since new. Since 45,000 miles all related circuits and components have been inspected and checked for proper operation. New crank sensor and electrical ignition switch. Code b2105 keeps recurring even without stall. All wiring connections and grounds have been cleaned and checked, new battery at 36,000. Had vehicle to dealer and they said they may not be able to find problem. We have stopped driving this vehicle even though we are still paying for it because we feel that it is not safe. My husband has 40 years as certified automotive mechanic and is very frustrated with this vehicle.

2007 jeep grand cherokee laredo - randomly the vehicle will not start, when turning the key to in the ignition you can hear the relay clicking, engine does not crank or start. When the key is returned to the off position the data display below the tachometer momentarily states that the transmission is overheated. The battery is fully charged and everything else, lights, horn, etc still work. There are no error codes dumped. The first attempt to fix this by the dealership was to replace the starter, now 4 months later the vehicle is doing the same exact thing. This has become a reliability issue in that there is no telling when this will occur, each time family members have been stranded with this vehicle, jeep dealership seems to be "stumped". I have read of many jeep vehicles that demonstrate this very same problem, without resolution. This can be an intermittent issue, usually have to wait until it becomes a "hard" fail before the dealership will look at it. This is extremely frustrating owning this vehicle not knowing when it will or will not start and whether the dealership can or cannot fix it!

I write this only because I just experience my fourth mechanical breakdown in three years. In december 2009, I experienced the first breakdown in what has become a string of malfunctions. The transmission on my 2007 grand cherokee laredo gave out at about 40,000 miles. When trying to start the vehicle, I got a 'transmission overheat' message on the dash display along with the engine malfunction indicator. I took it to the dealership where I purchased it and it took nearly a month for the repair shop to locate, receive and install the necessary parts. Apparently supply and demand had something to do with it, indicating to me that this was an issue nationwide. A month later, another malfunction, this time, the electronic shift module (esm) had died. Just over a year later, the same component (esm) died again (of course just out of warranty), this time while I was driving along rt. 50 outside of dc. Now, less than six months later, with less than 40,000 on the already replaced transmission, my transmission has blown again - same 'transmission overheat' message, same engine malfunction light, same undrivability. Clearly from seeing the comments on this forum as well as other reputable sites such as edmunds and consumer reports, the 2007 grand cherokee laredo has a long, long history of mechanical and electronic problems. I have a phone call scheduled with a case worker scheduled for tomorrow, 7/13/2012. They'll either make it right or I'll be taking my story to small claims court. I encourage everyone who's had issues with this model to do the same.
