2016 Jeep Patriot: won't start

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.

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.

The vehicle stalled sitting still. When I cranked the jeep it would not turn over. As I turned the ignition key it just kept on cranking with out me holding the key.

We have a jeep patriot 2016 and were told that there was a recall on it for the crankshaft sensor which effects the starter. We have been having issues with the jeep starting and told by a mechanic that it was under recall. We took it to the jeep dealer and they scheduled it to be fixed. We were then called and told that this vehicle missed the recall date by 2 months so it would not be covered by the recall and it would cost to have this fixed. It is the same issue that has been reported on other 2016 jeeps and this should be a recall on this vehicle as well. We are now having to pay to have this repair done when vehicles of the same year were recalled for the same issue! The vehicle was stationary when the issue started and it would not start. We actually had it hooked up to read what the issue was also. It identified an issue with the crankshaft sensor. The same reported recall issue!

I was going uphill on a rural road when my car powered down and the rpms dropped down to 0. It kicked right back in, it happened one more time on my way home through the city. When I got into my driveway, before I could come to a complete stop it dropped rpms and powered down. After a half an hour I went out to head to a dr. Appt and my jeep wouldn't start.

My car was parked at home in parking lot. I used car earlier during the morning and had no problems with it. During the afternoon I went outside to crank car and it started with no problems. I then realized I forgot something in my home and turned car off took key out the ignition and went to retrieve what I had forgotten. I came back out not even 30 seconds, attempted to crank car and the dash board lights, AC came on, but car would not crank. It made no noise to indicate it was trying to turn over nothing. After trying a few times I called geico to have someone come out to possibly jump start the car, but that person tested the battery, oil, alternator, and started and said none of them were a problem. I then ordered a tow truck thru geico, he arrived about an hour later and he immediately sat in vehicle and car cranked with no problems. The engine light on dash also disappeared. The next day I took the vehicle to have it checked again and I have a print out that shows that neither the battery, starter, alternator or engine oil were a factor. I haven't had any other issues with the car cranking since that day. No one seems to know why it would not start.
