Jeep Patriot won't start problems

Filed Aug 25, 2025 · Electrical, Engine · CA

While driving my 2016 Jeep Patriot on multiple occasions, the engine suddenly shuts off without warning. After shutting off the car would also have alot of issues restarting. I finally took it to multiple mechanics and they all indicated they couldn't find out exactly what was the problem, given nothing showed up on their diagnostics testing's. After the car finally wouldn't start anymore, i got it towed to the dealership and they diagnosed the car with failed crankshaft sensor (which has already been recalled on a chunk of the 2016 Jeep patriots manufactured).

Six months after we purchased our 2016 Jeep Patriot Sport 4w the check engine light illuminated on and off for a couple of weeks. After that time frame it became a permanent fixture. As well as unpredictable and frequent stalling while driving or stopping at red lights/deceleration of gas pedal of vehicle. The vehicle would not start again for hours...even days after these episodes making it difficult and unaffordable to operate safely. A diagnostic was performed when the vehicle decided to start days later and the crankshaft position sensor code was read by the trouble code. We then called a mobile mechanic who charged us $325 to replace the crankshaft position sensor/ relearn included to no avail. Although did confirm the part would need to be replaced. The vehicle hasn't started since the replacement therefor a relearn could not be performed. Researching the possible problems, I noticed many complaints on the same and similar models as well as a high rate of reoccurrence w the same parts (cam/crankshaft position sensor). We notified the dealership and they informed us it would be $199 to run a diagnostic if we could afford to have it towed to them... Witch we could not. I have included the receipt from the mobile mechanic and it is in fact available for inspection upon request.

CAMSHAFT and CRANKSHAFT position sensors keep failing. I have gotten these replaced at a local auto shop 4 times in the 3 years I've had the vehicle. Each time they're replaced the PCM is flashed but issue comes back a couple days to a week later either when coming to a stop at an intersection or when driving up to 50 miles per hour, the acceleration doesn't work properly and RPMS shoot down to zero and back up. Car has also shut off when coming to a stop under 5 MPH and sometimes starts up again. Engine light and TCS light both come on when either sensor fails, car runs rough or doesn't start resulting in a tow to a shop. This is a huge safety risk and can cause a crash at any time. VIN does not have recall, but has all the issues described in the recall.

My 2016 Jeep Patriot was taken in for intermittent stalling and my engine was stalling. This happened a few times. My car RPM went from 3 to 0 and I could not accelerate. I had to put the car in park and turn the car off and start it back up. The first time my car would not start back up right away. Luckily there was no one close enough behind me nor were I was going fast enough to be in an accident. I go it to a repair shop and was told my crankshaft and sensor would need to be replaced. My car is currently being serviced at Gandrud Chrysler Dodge Jeep Ram in Green Bay, Wisconsin. The phone number is (920) 468-1212. I previously looked up a recall for Jeep Patriots and there was a recall for crankshaft "Recall # [XXX]. Unfortunately my car was manufactured just after the date of [XXX] which is the cutoff of the recall. This recall is exactly what is currently being replaced on my car. I think this recall needs to be extended as this could have been a more serious accident and to help prevent more future accidents. My car should have been included in this recall.

Vehicle stalls and doesn't start. Would also occasionally shake and the check engine light comes on. Throttle body was replaced less than 1 year ago and it is currently not starting due to the same issue. Needs another throttle body. It's the position sensor that seems to go bad due to all the heat generating around it. Both times it really acted up once the weather warned. Unfortunately you can't just replace the sensor, the whole throttle body needs replaced. At $350 each from the factory. Online it seems like a lot of people are having the same problem.

I have a 2014 2.4L JEEP PATRIOT. I first noticed the problem when I was driving at 75 MPH between Mertzon Texas and Barnhart Texas, where there is no cell service unless you are on top of a hill. Then suddenly the check engine and the oil light came on and the vehicle began to lose speed no matter how much I pushed the gas peddle. The engine felt like it was running out of power and i was unable to accelerate, the engine began to stall and would not allow me to go over 15mph. The problem continued to get worse, while I pulled over and stopped, the engine would idle very heavily and sound rough. When I tried to proceed, the engine would stall, and my foot would be presing down on the gas pedalbut the car would not accelerate. Then after about a minute or the with the gas pedal down to the floor, the vehicle's rpms would jump and the it would go. But it continued the same pattern for about 15 miles, then it just died and would not start again for a few hours, but the issue was still the same, it would start but not move. Another issue is when the vehicle would be in park position and I would try to go in reverse, the engine would sound like it went into reverse, but it would not move, it would stall out and die. I have taken it to so many shops and they can not give an answer, they just say that the motor is blown. The problem is consistent with the NHS Recal-13V552000, so why does it still say that my vin in not affected when actually it is, but nothing is being done.

For the past several months we are having trouble with the computer issue with this vehicle. We took it to a repair shop and they confirmed, in fact one of the mechanics had the very same problem, that the computer is malfunctioning. Here is what is happening...the car won't start and as you turn the key it just hesitates and you pray it will start. The A/C won't come on...the clock on the dash does not show the correct time...the "bell" dings when you exit the vehicle even though there is no key in the ignition, the lights have been turned off, etc. It won't stop dinging until you shut the door. Also, the rear window defogger indicator light is flashing like warning you to turn it off. Also, the CD player won't eject a CD. Then come a few days later and none of this happens. It is always a gamble when you get in the Jeep wondering if it will start. I feel, since this has happened to other Jeeps, there should be a recall on this particular situation.

The unsealed main relay box is positioned directly below the lead-acid battery which leaks directly onto the cover, enters the relay box and destroys the leg and wiring connected to the automatic shutdown relay. This can occur both as the vehicle is operating or cause a no-crank/no-start situation, immobilizing the vehicle. In our case, the first time it occurred was in a parking lot but the issue is well documented on the internet and there are myriad youtube videos on the issue for many jeep and fca vehicles. This is enough of a known issue that fca has not addressed for many years now and we just paid $460.00 for the dealer to move the affected relay from the box to a less vulnerable location. It occurred a few times before the wiring failed completely, and in our case was in a stationary condition each time fortunately.
