2021 Jeep Cherokee

The service department where I bought the SUV said the power transfer unit was bad and the vehicle was unsafe to drive. So its been parked there in the back parking lot for three weeks. I had told them every time that I took it in for a oil change that there was a problem. They said it needed a software update, but it didn't help. Then after more than year and the forth time complaining about the noise and feel of the car, it's all of a sudden unsafe to drive and need to be parked until fixed.

The contact owns a 2021 Jeep Cherokee. The contact stated that while his wife was driving approximately 25 MPH, there was a clunking sound coming from the rear of the vehicle, and the vehicle would not properly accelerate. The vehicle was immediately driven to a nearby mechanic who diagnosed that the rear driveshaft had detached from the vehicle and was striking the ground. The rear driveshaft was replaced, and the vehicle was repaired. The local dealer had examined the vehicle and was unable to determine how the rear driveshaft had detached from the vehicle. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 27,364.

PTU in 2021 Jeep Cherokee with 50k miles went out causing a loss in power to the wheels while crossing a highway. Dealership put a new PTU and drive shaft in but said it was defective but they could turn off the Jeeps ability to transfer power from front to back until they got a new part. This caused my safety features such as front collision to be turned off. I assume they pulled a fuse for the transfer between front and rear meaning the new PTU was more than just not communicating with the electronics like the dealership said but was an actual defective unit. The last time it went out it also tore up a drive shaft. The replacement unit in the Jeep has always had a grinding sound and began to have what felt like transmission slip. I also started losing power and when the engine is turned off sometimes it won’t start even though it has power in the battery and the start turns. It is broke down again and going into the shop because the Jeep is still having drive issues along with new electrical ones and I am in danger of it losing power or transmission when crossing a highway. The dealer did tell me that many of the new PTUs are defective. I am surprised a dealership when send a customer back out in a vehicle they knew wouldn’t be safe and had a failed part.

While at a complete stop vehicle’s rpms went up and launched forward on its own. It continued to do so several times despite pressing the break pedal fully. Vehicle did the same thing only a couple of weeks after being purchased but I was unsure if it had been the vehicle or I eased up on the break a little too much. This latest time however it did it so many times that I was able to record it and share it with my dealership.

In May 2021 I leases a brand new car. In Jan 2021 I was driving my car and at a busy intersection, my car stalled. I just got a full tank of gas but the low fuel tank light came on. The car would not turn off, the clutch was stuck and I could not shift out of any gear. I brought my car in to the service center where I bought my car and let them know that I think electrical issues were causing problems with my fuel gauge and my clutch. They held on to my car from Jan 20-Mar 28th they could not say what electrical problems caused my car to stall or my fuel tank to register as low but they gave me a whole new transmission. At this time I had only about 2,700 miles on the car. Less than a month later I stalled again on a busy road but I was able to pull the car over and waited for a family member to arrive to help. After letting the car sit for a little I was able to start the car again however the low fuel light came back on and the engine light came on. Additionally this time I was not able to shut off the car, radio, blinkers did not work, as well as break lights did not work. I brought the car back in and expressed my concerns about the electrical problems causing saftey issues on April 20 2021. I drove to the dealership with my hazards in which it stalled 3 times on my way there. They had my car til April 26 and said a cluster of alerts came up and the reset them but they couldn't guarantee it wouldn't happen again. Only one day later I started my car to find the fuel tank alert on again and the car not being able to turn off and brake lights, signal lights were not working and the windshield wipers going crazy. I then called a tow truck to tow my car as it was unsafe to drive. Now my car has been in the shop since April 27 almost 50 days and counting and they still can't find what is causing the issues. They want to release my car again but cannot guarantee it will not happen again. I am terrified to drive the car as nothing was fixed and very unsafe.

The drivetrain failed while driving at 65 mph on a straight highway. Weather was sunny and warm at 11am. Suddenly there was no power going to the wheels. There were no vehicle warning lights or sounds. Stepping on the gas pedal resulted in a whinning noise. Because the engine was still running I had control over the steering and brakes. After stopping the vehicle on the shoulder of the road I put the vehicle in park. I then attempted to travel forward. Moving the shifter from park to drive the parking brake was automatically set on. I released the parking brake and applied slight pressure on the gas. There was a clicking noise and no attempt to move. I had the car towed to Tate Jeep of Frederick MD. I bought the car used from a Mazda dealership in Baltimore with 14,100 miles one month earlier.

While I was trying to get onto the interstate my vehicle would not accelerate. I tried to merge in with traffic but I was only going 35 and I almost hit someone. They stayed the same speed hoping I would speed up in front of them but I couldn’t. This put everyone around me at risk. I took my vh to the dealership. They called me today and told me they sold the rental I was in and that I needed to bring the car back. Also they ran some codes and my car is coming back fine. So they did not find a problem. I honestly feel they didn’t look they just wanted to sell the rental car. I’ve had no warning lamps at all come on but the transmission is slipping.
