2009 Jeep Patriot 4X4 Problems

What owners report

Owners of this model year most often describe stalling shortly after refueling, water leaking into the cabin through the roof/dome light, and front suspension or subframe rust found at inspection. Many reports come in at moderate to higher mileage, though several suspension and leak complaints appear well under 50,000 miles. Transmission overheating on long highway grades also shows up repeatedly, usually announced by a warning light before the vehicle limits speed.

   Fuel system

   Stalling or rough running after refueling

   • 16 complaints (27%)
   • median 98,000 mi at 8.5 yrs old (13 state mileage)
   • filed 2012–2019

   Owners describe the engine bucking, surging, or dying within a short distance of filling the tank, sometimes repeatedly on the same trip. Some also report that the fuel nozzle keeps clicking off, making a fill-up take many minutes, and that fuel can spit back out. Several say dealers diagnosed a problem in the fuel tank (an internal valve or sensor) and recommended replacing the whole tank; others report no diagnosis and no resolution. Most often reported between roughly 45,000 and 135,000 miles, and usually immediately after a fill-up.

   What to check: Ask whether the fuel tank or any in-tank valve has been serviced, and test a fill-up during the test drive. Note whether the nozzle clicks off repeatedly or the engine stumbles shortly after leaving the station.

   “After refueling, the vehicle acts like it wants to stall and has stalled on some occasions. This is concerning to me because, I have to put the vehicle in park and restart it. I am afraid when this happens that someone behind me in traffic may slam into my Jeep.. I put a recent date below, but it has been ongoing off and on since I bought it last year.”

   NHTSA complaint #10981671, filed 2017-05, 99,000 miles

   “Car engine dies after filling gas tank approximately 1 mile away from gas station every time. My car has died in an intersection when making a turn against oncoming traffic. Car usually dies after idling at a stop light and then upon acceleration it just dies. Car has 70,000 miles and from my research it seems to be a common problem.”

   Body and structure

   Rusted front or rear subframe and crossmember

   • 9 complaints (15%)
   • median 108,000 mi at 8.2 yrs old (9 state mileage, few)
   • filed 2015–2018

   Complaints describe heavy corrosion on the front crossmember or rear subframe discovered during service or inspection, in some cases to the point of cracking or a broken mount. Owners report being told the vehicle should not be driven until the frame section is replaced, and that the repair was not covered. One report describes a rear axle shifting out of position after the subframe cracked. Typically reported between about 70,000 and 130,000 miles on older vehicles, often in states with road salt; a few appear much earlier.

   What to check: Get the vehicle on a lift and inspect the front crossmember and rear subframe for scaling rust, especially around mounting points and sway bar brackets. Ask whether any frame section has been replaced.

   “While driving on a residential road the 2009 Jeep patriot's subframe broke. Because of this my vehicle almost lost the passenger tire. Had it been on the freeway I would have been severely injured. After being inspected by the mechanic he has never seen rust this bad and it's much more deteriorated than any other part of the underbody. This is not normal wear and tear. A 9 year old vehicle should not be experiencing this sort of deterioration. …”

   NHTSA complaint #11123180, filed 2018-08, 120,000 miles

   “2009 Jeep PATRIOT 4X4, 20,800 miles bad enough I had to replace the front left lower ball joint at this low mileage, but while in the shop my mechanic calls me to inform me that the k-frame is rotted out and needs to be replaced. A k frame or cross member on a car is the part of the car's frame bolted beneath the underside of the vehicle. The k cross member, which features engine mounts, is used to support a longitudinally mounted transmission. The k frame enables better handling and alignment with respect to suspension. …”

   Body and structure

   Water leaking through roof/dome light

   • 6 complaints (10%)
   • median 39,000 mi at 4.2 yrs old (5 state mileage, few)
   • filed 2011–2014

   Complaints describe water pouring from the front dome or map light and soaking the front floor, sometimes with water reaching the dash or behind the accelerator. Owners of vehicles with a sunroof link it to blocked or misrouted drain tubes, and some report repeat visits where the dealer cleared the drains without a lasting fix. A few mention electrical symptoms such as lights flashing or the vehicle not shutting off after the leak. Reported from under 10,000 miles up to about 75,000 miles, in rain or even heavy dew, mostly on sunroof-equipped vehicles.

   What to check: Look for water stains or discoloration around the headliner, dome light, and front carpets, and check that the sunroof drains flow freely. A test with a hose over the roof can reveal a leak.

   “Just purchased the 2009 Jeep patriot for my son, it rained and it is leaking water in the dome lights and behind the accelerator. I am scared there will be electrical damage as well as mold and mildew. I have started looking up issues online and have found many people having the same issues. Shouldn't Jeep be held responsible????”

   NHTSA complaint #10487515, filed 2012-12, 74,000 miles

   “Water keeps flowing from the ceiling dome light. I have had it to the dealer several times, they keep blowing out the roof drains, and it keeps happening. I went out to the driveway and heard a humming sound coming from under the hood, and water was pouring from the ceiling light . I started the vehicle, and all the lights began flashing, and when I turned the key off, it kept running. I could not turn the car off!!! I had to disconnect the battery!!”

   Suspension

   Front ball joints and control arms worn early

   • 5 complaints (8%)
   • median 35,100 mi at 3.7 yrs old (5 state mileage, few)
   • filed 2012–2017

   Owners describe clunking or rattling from the front end over bumps, a loose or floaty feel in the steering, and uneven tire wear. Several say the ball joints were found worn or separated during routine service, sometimes at very low mileage, and that the dealer replaced the whole control arm rather than the joint alone. Some report the repair was covered under warranty, others paid out of pocket. Many reports fall between about 12,000 and 50,000 miles, with a few higher-mileage cases; a related service bulletin concerns lower control arm bolt tightness.

   1 related service bulletin

   What to check: Have a shop check the front ball joints and control arm bolts for play, and listen for clunking at low speed over bumps during the test drive. Ask whether the control arms have already been replaced.

   “Brought my vehicle for brakes and inspection and received a call from the garage saying I needed to replace all 4 ball joints. They said the left front one was extremely loose and barely hanging on. I researched the web and found many incidents of bad ball joints on this vehicle with an explanation from local dealer shops that there was a bad batch installed initially. The repairs cost me over $700 because the 3 year warranty had run out even though the mileage is still within range. …”

   NHTSA complaint #10592371, filed 2014-05, 35,100 miles

   “At less than 370000 miles, (just out of warranty) I noticed a clunking and rattling noise from the front driver side of my 2009 Jeep patriot. After a few days it spread to the passenger side front. When taking off or braking, especially around 5-10 MPH, the clunking is really loud. I drove to chrysler in wiesbaden, germany, and informed them that I believe it was a lower ball joint making the noise on both sides. Later they called me and said I was right, and they do not do ball joint repair, they replace the control arm. …”

   Transmission and drivetrain

   Transmission overheating and limp mode

   Mentioned in 4 of 58 sampled complaints

   Owners describe a transmission overheat warning light followed by the vehicle limiting speed on its own, often on long highway grades or sustained higher-rpm driving. Some report the condition after as little as 15 minutes of normal driving and say fluid changes or an added cooler did not resolve it. Others mention harsh or delayed shifting and a stored high-temperature code. Mostly reported between about 65,000 and 125,000 miles, typically during sustained highway or uphill driving.

   2 related service bulletins

   What to check: Ask whether the transmission has shown an overheat warning or stored high-temperature codes, and take a highway test drive with a long climb to see whether the warning appears. Service bulletins describe valve body related overdrive cycling, so ask whether that has been addressed.

   “The transmission over heats and the speed slows down automatic and will cause the car to stall.this happens on all long road trips. The chain drive transmission is at fault. Jeep covered this up by putting censor on cooling part to mass the real fault. This has happen three times always on long mileage trips. Thank you”

   NHTSA complaint #10722377, filed 2015-05, 98,000 miles

   “My Jeep patriot has a very unusual problem of going into limp mode under normal operating conditions--even after as little of 15 minutes of driving. The transmission overheat light comes on, and the vehicle's on-board computer forces the vehicle down to slow, sub-highway speeds--even as slow as 35 MPH. The problem has been very dangerous for us (especially on the freeway) and occurs under normal (and even cold temperatures). …”

   NHTSA complaint #10551726, filed 2013-11, 65,000 miles

Buying note. Give this model year a careful pre-purchase inspection, with particular attention to underbody rust on the subframe and crossmember, front suspension play, and any history of post-refuel stalling or water leaks. Service records showing suspension and fuel tank work, plus a highway test drive, are worth asking for.
