Notes: The 2012 Grand Cherokee hasn't seen the same complaint volume as the 2011, at least not yet.

It's worth noting both model years are part of a class-action lawsuit that focuses on a defective TIPM and a long wait for replacement parts.

The 2012 also received national attention after it failed a Swedish Magazine's "moose test". The test measures a vehicle's ability to swerve out of the way of an obstacle you wouldn't want to hit while driving down the road ... like a moose.

engine turns over, won't start

I do not understand why a TIPM is not a recall for my year and model when this seem to be a common problem with this line. It is so sad that the Cherokee is such a beautiful vehicle with so many problems. This is leaving a very bitter taste in my mouth. Please advise what kind of compensation can be extended to me because locally this part is costing some $1,300.00 and that does not include labor. I would greatly appreciate any help given in this matter.



Update from Dec 17, 2017: I took the jeep to the dealer on Monday Dec 11th. They replaced the fuel pump relay and all was good.

Grand Cherokee Limited 5.7L

  • Automatic transmission
  • 41,000 miles

Jeep overheated. I turned the Jeep off and waited 1/2 an hour, then tried to start it. Won't start. Had it towed to a Jeep dealer close to my residence. Dealer could not start the vehicle but diagnosed the problem with the overheating as bad water pump. This was replaced under power train warranty.

However it was determined that I needed a starter, parts and labor $700.00. I was told that after the starter is replaced and the vehicle is running, then they can diagnose whether there are further problems with the vehicle. I am really bothered by all of this. The vehicle was running fine for the most part now with only 41k on it a lot of problems.

This Jeep has the Hemi 5.7L engine, which I thought was a great engine. The day of the overheating, the oil gauge went up to 310, engine light on and a few other lights also, I managed to get off the very crowded highway. I have read of many similar problems occurring on these vehicles which should be addressed by Chrysler.

It is really shameful that a company like this would overlook all these problems which some could cause fatalities. If someone from Chrysler should read this complaint, please look into some of the problems these vehicles are having.

I was told there was a recall for the fuel pump relay and it was fixed however now the fuel pump needs to be replaced. Left me wondering if the fuel pump relay caused the fuel pump to malfunction. The person from the dealerships service department stated there were numerous instances where fuel pumps had to be replaced in Jeeps.

My 2012 grand cherokee overland with just 24000 miles refused to start one night far from home, this happened one month ago. I thought the battery was getting weak, suddenly after several attempts it started. It happened again last week after several attempts it started again. I felted a little disapointed and shameful, knowing that this is a new vehicle, and it cost quite a bit of cash. However I thought it was just a temporary malfunction until yesterday Nov, 02nd 2015 it happened again. was angry about that problem. this morning it just didn't start.

Unfortunately I leave in Dominica and there is no Chrysler dealer on the island, so it would appear that am stuck with this problem.

This vehicle is hit or miss when it comes to starting. When you push the button it cranks but will not start. Once, I pushed the button and it kept cranking over and over for 10 seconds all on its own without me touching anything! All Chrysler will do is apologize. It was diagnosed with a recall issue TIPM...but they don't even have the part built yet! I had to pay for a rental the day I had to put it in for evaluation! I bought American and this is what I get??!! I am a home care nurse and I visit several homes a day in all kinds of neighborhoods. I have a time limit to see and get to my next patient...but I never know when the car may not start. I'm so aggravated and disgusted...I don't know what to do. This is totally unacceptable !!

Grand Cherokee Limited 3.2L V6

  • Automatic transmission
  • 27,000 miles

I just purchased this vehicle used with only 26000 miles, less than a month ago. The dealership never informed me of any recalls and this particular model has SIX recalls. Today it just wouldn't turn over. I had to wait and keep trying to start it. Finally it started after waiting 10 min and 7 attempts. I am NOT happy and totally disgusted with Jeep. This is my 5th Jeep vehicle and my LAST!!

Update from Mar 22, 2016: TIPM recalled brought Jeep in for recall. One month later, engine lights-fuel light came on. $400 later, lights off, but 3 weeks after that she wouldn't start again. Keeps trying to turn on and gets stuck on.

Don't know what causes this but occasionally the push button start just doesn't work. Sometimes nothing happens, other times the car just cranks. Either way I need to cycle through by pushing the button several time and then try again to start the car. I've read many posts this could be the TIPM or something else but just don't know. It's a huge problem and needs to be addressed.

The engine sporadically will not start. This leaves the vehicle undependable and difficult to use when you can get stuck at any time.

Grand Cherokee V6

  • Automatic transmission

This is a known problem for Jeep -- the infamous intermittent no start. The first time I took it in, they applied three flash fixes (software). It was unsuccessful.

A week later I took it in and they installed a new wiring harness for the fuel pump. It was unsuccessful.

The third time I took it in -- a week later -- they couldn't get it to intermittent no start (hello? That's why they call it intermittent!). So they did nothing. Explained to me it wasn't prudent for them to just replace parts at random.

I explained no need to replace them at random -- they know the problem -- the TIPM, or at least that's one fix. The Service Manager was pretty nasty, essentially blaming me for the problem, or at least blaming me for expecting him to be able to fix something he can't get to do again (intermittent no start).

I tried to point him to a Chrysler website that showed the possible fixes, but he wasn't interested.

A REAL black eye for Chrysler, and I will never purchase another Chrysler product again. Now I just need to figure out what to do with a vehicle that I can't trust to take anyplace where AAA isn't immediately available. Piece of junk, but looks nice going down the road -- behind a tow truck!

Grand Cherokee 3.2V6

  • Automatic transmission
  • 43,000 miles

So,let me start by saying how upset I am with Jeep! My 2012 Jeep Grand Cherokee Laredo has left me stranded at all hours with my children in the car .I have arrived late to work several times because the car has stalled or not turned on at all. It makes a long clanking sound then dies. Sometimes I get it working after fifteen minutes. I was driving when it just died and I was almost hit by a bus!

The car has a mind of its own it accelerates on its own. Lights, airbags and symbols turn on tells me my key has left the car when it hasn't . I had to buy a new alternator and battery. Then I did some research and found out that many people had the same problem as I did and JEEP knows all about theses problems they have put faulty TIMP in these cars and do not want to put a recall.

Even though this is a safety hazard which can kill people due to their faulty equipment. I just recently found out about this after several months. The Jeep dealer told me that the problem was the TIMP, but a recall was just issued for 2010-July 2011models. My vehicle was a 2012 but it has the same problem and my car was manufactured in 2011in August. They won't cover it and I think that's crazy!

Many cars with my model have had the same complaints and jeep refuses to take responsibility for the faulty parts!!! What is it going to take many more lives at stake for Jeep to do what is right! So the faulty TIMP has the fuel pump running constantly which drains the battery it runs when the car is off this is so dangerous in many levels and JEEP DOESN'T EVEN HAVE THE PARTS TO FIX THIS. They offer a temporary solution to install a fuel pump harness bypass so that the fuel pump turns off this is a band-aid and an expensive one that costs approx.$1200 after parts and labor, that has come out my pocket not to mention the $1400 I have already spent on a new alternator and battery which drained cause of this TIMP.

Let me then tell you that after I installed a new alternator now there's a recall on it that comes out on November 26 besides two others how many other faulty equipment has Jeep used and the cost comes out of my pocket. I am so sick of Jeep! They are horrible to their customers and something must be done! Don't buy any Jeep! Your life depends on it!

Dealer says they have no idea what the problem is. After 10 minutes of research, I find it could be the TIPM and Chrysler knows about it. Very disappointing.

Grand Cherokee Laredo 3.6L

  • Automatic transmission
  • 37,000 miles

Well, well, well, where to start? How about I start by saying how much I LOVE my car of two years!! Until today that is, she decided to completely die in my garage and also do a total lock down with my daughter and I in the car.

It all started a couple of days ago when it started having problems. At first the key fob batteries needed changed. Easy fix. Then it started chugging or stuttering before it would start (that only happened in the morning for a couple days), so I took to a mechanic. He said there weren't any codes leading him to believe maybe the fuel pump. So we waited for another day when I could leave the car long enough to get a better diagnosis. Then today I packed the car with all our usual stuff before heading to drop my daughter off at daycare and I to work, but low and behold my car didn't start.

I'm talking dead... No sputter no nothing. It wouldn't even let me have my key fob back (I didn't use the push start because I figured out that it would start better with it versus the push button) as well as no lights, no door locking ability. So you guessed it, I tried to lock/unlock the car just checking to see if anything worked. Me being a genius decided to push the lock down and try again. Why? I have no clue but it locked my door and I had no way to open!!! Do you have any idea how scary this was for me? It was 92 today and I was in the garage with my 1 year old daughter. Luckily it didn't auto lock any other doors so I was able to get out but my battery was dead.

Praying to the car gods that this has been the problem the whole time. What a cheap fix! My husband changed the old battery for a new one ($200 later) and BAM Lights, camera... But no action. Back to square one, stutter but no start or start and die. It's hopeless! After researching this problem I found the issue to be a TIMP problem and now an aware that I am not alone. There is no recall on this?! Ridiculous!!! This is my 2nd Jeep and we wanted a 3rd but after zero response to this could-be life threatening issue from Chrysler, I'm physically sick and scared of Jeep.

My Jeep Grand Cherokee Overland 2012 was having issues for a week where the engine would crank but it would sound like it was not getting gas. This problem made me late to work on more than one occasion. Sometimes it would take as many as 20 attempts and 30-40 minutes for the vehicle to start.

After doing some research and taking it to the dealer I Found out to TIPM module had an internal failure. This cost me nearly $1800 with the parts and labor. Not to mention the TIPM was on back order and I was without a vehicle for 10 days. This was such an expensive inconvenience that conveniently went wrong just months after the 36000 mile warranty. This is clearly a problem that needs to be addressed.

Car will not start on the first or second crank. The problem started at around 37000 miles. Took to dealer twice before replacing the TIPM. Still doesn't work and at the shop again.

Also 6 months ago one of the headlights will go off and come back on. It took two visits to have it replaced, due to a faulty fuse.

  • Automatic transmission

On 6/24, I filled a nearly empty tank with gas. The next morning, truck won't start. Tow it to the dealer, they say there's water in the gas tank. $410 later on a non-warranty repair (dry gas + some Wynn's pure-profit cleaning solution), I pick it up. I complained to the gas station, who gave me the "I've owned this station for 8 years and NO ONE has ever had a problem with my gas". Yeah and no one has ever gotten food poisoning at McDonalds either and they sell lots of hamburgers. Truck works for a few days and then it won't start again. Towed it back to the dealer (after waiting 2 1/2 hours for them to get it - thankfully it was in front of my house). Now it's the left fuel filter. They replace it under warranty within 2 days (after telling me it would take 7-10 days to get, and oh by the way, Chrysler's policy is no loaner cars). I asked if this could be related to the water in the tank? Maybe, not sure. Picked it up, and a few days later, same problem. It doesn't start. Waited a few hours, it started up like nothing ever happened. Called back, now they say to check the battery. I said goodbye Jeep. Two things I expect a vehicle to do. Start. Stop. Everything else is superfluous. Even if Start or Stop doesn't Start or Stop, as long as you can correctly diagnose and fix it, I'm ok with it. Too bad too, because other than the OEM all season Michelin car tires which wore out after <20K miles, it was an enjoyable truck to putz around in. After I sold my 1988 Cherokee I promised myself never again. Ask me again in 2026.
