2017 Jeep Wrangler Powertrain & Transmission Problems

The contact owns a 2017 Jeep Wrangler. The contact stated that while driving approximately 30-45 MPH, the vehicle lost power. On another occasion, while driving at 20 MPH, the vehicle lost motive power. While shifting into gear, the vehicle failed to respond as intended. The check engine warning light illuminated after the failure. The driver was able to pull over safely. The vehicle was running, and the heat was functioning. The vehicle was towed to a AAA Service Center, where the filter and oil were changed; however, the failure reoccurred. The vehicle was towed to AAA again, but no assistance was provided. The vehicle was taken to the local dealer, where it was diagnosed, and it was determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 100,000.

I bought my 2017 jeep with 29,000 miles on it. I had an issue with the rear driverside brake locking up around 40,000 miles. I feel this is a safety issue due to how hot the brakes got and at times would be smoking. It being the weekend and my only vehicle, repaired myself for approximately $280. I have had to replace several coil packs around $50,000 miles. My main complaint today, at 66,000 miles it seems to be leaking oil. I took to mechanic this morning and was told this is a common problem with jeeps. The oil cooler housing is cracked and leaking. This part is made out of plastic. The repair for this is going to cost $1200 to $1500. I have read complaints regarding this issue and do not understand why this hasn't been recalled. This is a major safety concern and could possibly cause a fire. I have owned jeeps my whole life and as of today, I will never purchase another. The jeep brand has declined in reliability and has proved to be a huge financial mistake.

Parts of the manual transmission are failing and appear in the bottom of the transmission when changing the fluid. It appears to be part of the synchro. This is apparently not uncommon for these manual transmissions. There were no warning lamps or messages indicating a failure or problem with the transmission. A transmission failure can startle a driver and cause an accident. It did not in this case.

Transmission clunking when changing gears, while my abs light is on. The break pedals rumble and the car is scary to drive. These issues are with a faulty abs control module.

Have the rear axle gears chipping/breaking off. Have mentioned this several times to dealer and they said the noise is normal for Jeeps. Took to independent repair shop and he found the gear issue, and asked me if anyone has worked on this rear end before, which would be no. He stated it looks as if someone has broke the original seal on it. I bought it at Performance CJDR in Delaware Ohio, and I'm wondering if something happened to it before I took ownership of vehicle. In process of repair at Bobbitt's Automotive repair in Lancaster Ohio... On my oil changes, the Rear Differential has always been checked OK... Now that vehicle is out of Power train Warranty this happens... My feeling is that this was always an issue with this vehicle, and was being covered up

Transmission failure.

Recurrent transmission pan gasket leaking. Repaired and replaced pan and gasket in March 2024 and reoccurred December 2024. Uploaded March Report, currently at dealer for repair 2nd incident now. Vehicles manufactured Nov 2016 had a recall for this same issue but this vehicle wasn’t included due to it being a couple months manufactured. Likely should have been included.

We were driving home from about a location an hour away. We were almost to our home when the transmission started to slip. The hot oil light came on as we were trying to ascend our hill where we live. We all of the sudden saw flames coming out the side of the vehicle. We were able to exit the vehicle and get to safety but the jeep burned completely to the ground. There was only 60k miles on it and it had been well maintained.

Oil filter housing is made of plastic and over time the plastic, exposed to heat cycle and elements from being under the plenum, becomes brittle and cracks. The cracks in the oil filter housing create a susbtantial oil leak that drips engine oil onto the exhaust and is a potential for a fire. If the oil level is not properly maintained it could also create a lack of lubrication on the engine for a potential engine lock up while being driven.

When driving at highway speed of appx. 60mph, driver heard a loud pop followed by grinding from under the vehicle. Driver pulled over, and assessed for visible damage, none was seen. A tow truck was called, as the severe grinding sound continued if the vehicle moved at all. It was taken back to the dealership where they discovered that the front driveshaft was completely destroyed. No one was injured, however had this happened during busy traffic it could have caused an incident. The front driveshaft, along with all applicable seals were replaced, at the owners expense as were the towing costs. No cause was found. See also NHTSA ID number: 11156532. My incident was not as severe, however very similar.

Faulty torque converter causes vehicle to stall.

Vehicle stalls when going into reverse mainly during first start of the day, but has happened throughout the day as well. Many people in online wrangler forums are attributing this to a faulty torque converter. No symptoms prior to this failure but it’s affecting many jeeps with low mileage like mine.

In November 2019, 47,000 miles I began experiencing issues with the vehicle popping out of reverse and grinding gears. A shift fork was replaced under warranty. Now, at 68,000 miles I am experiencing the exact same issue. The part is now out of 2 year warranty.

The plastic oil filter housing cracked leading to large oil leaks. This had been leaking for awhile and was not immediately noticed due to its placement in the valley between cylinder banks atop the engine. While investigating separate U-joint noise and driveshaft vibration that came on suddenly at 58,000 miles I found oil all over the driveshaft and traced it to the cracked housing. The repair was ~$650. Mechanics stated this is a common issue when oil change technicians over tighten the filter in the plastic housing.

BOUGHT THE VEHICLE NEW IN 2017, AND IN MID-2018, HAD A SYNCHRONIZING ARM REPAIRED, AS THE TRANSMISSION WAS SLIPPING OUT OF REVERSE. IN 2019, HAD IT LOOKED AT AGAIN BECAUSE IT WAS SLIPPING OUT OF 4TH GEAR, AND NOTHING WAS FOUND. IN LATE 2020, HAD IT IN TO CHECK A CREAKING NOISE WHEN DEPRESSING THE CLUTCH (LOCAL TRANSMISSION REPAIR SHOP), AND IT WAS FULL OF RUST, THEY SAID IT NEEDED REPLACED SOMETIME SOON. SO WE TOOK IT IN NOW (FEB. 2021) AND THEY SUGGESTED THAT THE TRANSMISSION NEEDED REPLACED AS WELL BECAUSE IT SLIPPED OUT OF 4TH FOR THEM WHEN THEY DROVE IT. CALLED THE DEALERSHIP, THEY RECOMMENDED CALLING CHRYSLER, WHO OPENED A CASE, AND NOW I'M TAKING IT IN TO HAVE IT DIAGNOSED AT THE DEALERSHIP AND FOLLOWED UP THROUGH THE CASE AT CHRYSLER. THIS SEEMS TO BE AN ISSUE, AS I'VE READ SEVERAL COMPLAINTS ABOUT THE SAME PROBLEMS AND FIXES.
