Software problems of the 2006 Jeep Grand Cherokee

During routine visits to my neighborhood supermarket, I've noticed while driving the rpm meter was going up and down at a stand-still. Now the vehicle was maintenance regularly and I have had issues before I've replaced the egr valve, throttle position sensor, spark plugs, pcv valve, automatic transmission oil cooler, a/c compressor even replaced the crankshaft position sensor. The truck also seems to lack power either that being an old software that it is using or the overall drivetrain is just abysmal. There also seems to be a loud thud that comes from directly under the vehicle when engaging p r n & d. Either the bushings are worn or the driveshaft is worn. The truck has been multi point checked at a local cdj dealership and it passed. Also the ignition switch was replaced on a recall. Going at low rpms, I also noticed that when going from 15-30 mph there seems to be a delay in travel as the truck will seem to be lagging or wants to slow down when my foot isn't on the accelerator. When in motion, going around 60-80 mph, the vehicle seems to have a moderate shake as in it vibrates from the undercarriage into the cabin area. It will feel like you're on a rollercoaster and the vehicle is just rumbling down the road. It feels safe at times, but when the �service 4wd� light appears it becomes almost frightening to drive the truck as it requires more attention then any other vehicle I've encountered. Also going back to the lag, you'll hear a chain-like sound as if the differential has an issue. I've gotten most of the front-end replaced: tire-rods, ball-joints, cv-shafts/axles, struts, stabilizer links and more. Now when turning the truck, there seems to be a lack of power as well. I had the battery and alternator tested and they both came back good. I find it hard to believe that internally the truck just wasn't meant to hold up.

2006 Jeep Grand Cherokee issues with the Chrysler recall n23 the consumer stated shortly after having his vehicle serviced at the dealer for the recall, when he used the 4-wheel low the driver information center displayed service 4wd system. The system would not shift into 4 wheel low range. The consumer returned to the dealer where they reprogrammed the final drive control module. Shortly thereafter, the service 4wd system displayed again. The consumer learned a revised software program was written for the final drive control module, because the program may have been installed incorrectly.

2006 Jeep Grand Cherokee consumer complains that recall was performed eight times and problem still exist the consumer stated shortly after the recall was performed, a message appeared on the dashboard that stated service 4-wheel drive. The consumer took the vehicle to the dealer. An inspection revealed the transfer case actuator was faulty, which was directly related to the recall. The dealer performed the recall again, which did not resolve the problem. Customer service, informed the consumer to go to another dealer where they would replace the transfer case actuator. However, the dealer only reprogrammed the software update, which they did three times. Three weeks later, the consumer went to another dealer, and they informed him the recall needed to be done again. Recall # 13v175000. Customer follow-up. Updated 01/28/15.

N23 recall was performed to keep transfer case from shifting into neutral caused by cracked circuit board. The "fix" to this was to flash the software to make it impossible for the Jeep to shift into neutral and 4wd low. Now every vehicle that has had this recall done is unable to tow their vehicle behind a camper because the transfer case can not shift into neutral, and 4wd low is inoperable as well. Chrysler has claimed that the n23 recall has nothing to do with all of these vehicles losing 4wd low even though everyone that has had this recall done has lost neutral and 4 lo. This cheap fix has left thousands of people who spent a lot of money on these expensive vehicles without the best feature of the vehicle, 4 lo. Most people buy these Jeeps because of their 4wd capability. Resale on a vehicle like this has gone right out the window with the loss of this feature. . Read more...

Tl- the contact owns a 2006 Jeep Grand Cherokee. The contact had received NHTSA campaign number:13v175000(electrical system , power train) and had taken the vehicle to the dealer to service the vehicle under the recall. The dealer was expected to re-flash the final drive controller which governs the transfer with new software. The vehicle was serviced,however, the contact had began to experience the four wheel drive malfunctions. The service four wheel driving unit warning light had illuminated and the gears would not shift into four wheel drive. The vehicle was taken back to the dealer for a diagnosis and the they had re flashed the system,however,the failure recurred. The contact stated on another occasion the gear had shifted into four wheel drive,however,would not shift from the gear. The vehicle was taken back to the dealer for a diagnosis and the mechanic stated that the actuator motor needed to be replaced. The vehicle had not been repaired. The contact also stated that the failures had not recurred until the vehicle as taken to the dealer under the recall. The manufacturer had not been notified of the failure and the ,the approximate failure mileage was 45,0000 the VIN was unavailable. Gb.

I recieved a recall letter in June 2013 from Chrysler recall n23/NHTSA 13v-175 transfer case actuator. Stating software was not available just yet to fix. Then in August 2013 recieved a second recall notice explaining that the software is now available for the recall to be resolved. All I have to do is go to a Chrysler/Dodge/Jeep dealership and have the software reprogram the final drive controller module. On August 13/2013 I had the recall serviced at johnson Dodge dealership in budd lake NJ ( 481 rt 46 budd lake NJ 07828). They did service my vehicle for said recall. The next day and everyday since I have a warning light on my dash stating""service 4wd system". I read the car manual and did some trouble shooting, but light still on. I tried to put vehicle into 4wd lo, as instructed by the car manual. Result, is doesn't go into 4wd lo, warning message still coming on. I made an appointment (August 22/2013) for the same dealer to inspect this issue because I do believe possibly something was either done incorrectly, or wrong software. End result from second visit to dealer is , my transfer case actuator needs replacing !! ($600 plus tax) . They will replace it, but I feel the two issues are related, and I should not have to pay the bill. The dealer reinspected all above components and stated the software is not working properly with the actuator? so end result is they want to replace the actuator. My original recall letter said I may have a fault in the actuator, but the second letter stated for the new software to fix all. The dealer said thats all they can do! call Chrysler and see what they say. Tried to call a second dealer, ( dover Dodge in randolph & rockaway NJ) and still waiting for a call back. I then called a 800# for Chrysler a customer hot line (800-992-1997) given to me by dealer, those too, I'm waiting on a resolution. Thank you dan strelec.

The Grand Cherokee stalled at a light on a hill. Restarted it and but it back in drive but vehicle continued to roll back almost rolling into car behind. Stalled 4 more times but in parking lots and non busy roads. Took it back to dealer where they updated software on computer and said it was fixed. Then stalled on a busy highway and was almost rear ended because vehicle stalled and wouldn't go into gear. Then parked it in parking lot and it stalled in park.

2006 Jeep Grand Cherokee. Consumer requests reimbursement for recall repairs. The consumer stated the costly repair of the shifter assembly did not successfully address the real defective part, the final drive controller module software, which was finally made public in 2013. In early 2010, the vehicle unintentionally shifted from drive into neutral, while the consumer was driving. Luckily, she was able to coast out of the roadway into a parking lot. The dealer mistakenly diagnosed the condition as a defective shifter and replaced it. At the end of may 2011, the vehicle once again shifted from drive into neutral on its own. The consumer no longer owns the vehicle.

Dealer carl burger Dodge and Chrysler is aware of a defective 4wd warning light (Chrysler service bulletin no. 21-014-06 rev a dated Nov. 2, 2006), that when I brought my vehicle in to service on December 12, 2007, they demanded to charge me $75. 00 (which I actually paid). I objected and raised the issue with both the service advisor and the service manager. They claimed because my mileage was slightly beyond 36,000 miles (37,912 miles to be exact), they had no obligation to diagnose and correct a known manufacturer's defect. This is wrong as a matter of law.

I bought my 2006 Jeep Grand Cherokee laredo 4x4 used at 40,000 a year ago this month. Shortly after owning it it started stalling while in motion or stopped in gear such as a traffic light. When sitting still, coasting and slowing down, the vehicle would die. The instrument panel did not light up and everything seemed normal until I took my foot off the brake to accelerate or just accelerated from a coast (such as a school zone slowly moving traffic), then I would realize the car had stalled. If I was on a hill going up the car would take off backwards. Dies turning into parking lots, etc. I loose power steering. The brakes stopped me if I applied them. However, if I was in the forward moving position, I would just throw it in neutral and re-start the engine without problem. This concerned me, because I buy my vehicles used, I did not know if dirty injectors and throttle body was causing carbon residue to clog the injectors so I had it all cleaned. That did not fix the problem. I started researching on this site and spoke to the guys that do my service. The researched and found a notice about safety. I went to Jeep website and found that there was such a notice about the brake system failure but no recall. Several weeks later I received a recall notice and 2 computer flash updates were needed. This fixed my problem, at least since late November 2007.
