2020 JEEP WRANGLER Complaints

An internal defect in the 2014-2020 Jeep Wranglers with the 3.6L Pentastar V6 engine affects its rocker arms, lifters, and related valvetrain components, including the engine control module (ECM) software that controls the precise timing and function of the lifters. Specifically, the rollers of a Pentastar engine’s rocker arms prematurely wear down, become loose, and then drop, which shifts the rocker arm out of alignment. The rocker arms then come into contact with the cam, scraping both components and creating metal debris. This Pentastar V6 engine defect creates an audible ticking sound that stems from metal particles and debris from the failed rocker arms and other components, contaminating the engine oil and circulating throughout the engine. This defect also causes engine misfires, resulting in bucking and surging, decreased engine performance, hesitation, loss of power, premature wear on internal components, and eventually catastrophic engine failure. The check engine light came on in my 2020 Jeep Wrangler with 69,000 miles. After having it read by a dealer, it showed the P219A code, Bank 1 air/fuel imbalance. The dealership told me that if the Jeep was running fine, I did not have to worry about it, as it was likely an O2 sensor. The code was cleared, and the P219A code returned the following day. It was driven approximately 500 miles before noticing that it began idling roughly and had an engine tick, which the dealership confirmed to be a valvetrain issue. The rocker arms, lifters, valves, and camshaft components of the Pentastar V6 engine in my 2020 Jeep Wrangler with 70,000 miles have failed. Three Jeep dealerships in my area and MANY online forums stated that this is a common occurrence with this engine, which has escalated my concern about this problem.

This particular jeep has been in 2 accidents where partial front and complete front impact occurred with zero airbag deployment. 1st wreck was 33k in damages with a bent frame and second was 10k . Both accidents bumpers needed replaced. Aug 28 2023 wreck was Jeep struck power pole [broke in two] at around 45mph and Feb 11 2024 centered a tree after striking a deer 15mph

STEERING WANDERS AS IF SOMETHING IS LOOSE IN THE STEERING MECHANISM. IT FEELS LIKE IT WOULD LIKE TO GET INTO A WOBBLE IF I HIT A BUMP OR RUT IN THE ROAD. I HAD IT LOOKED AT AND MECHANIC FOUND NOTHING WRONG. HE RE-BALANCED THE FRONT TIRES BUT IT STILL WANTS TO WANDER AS IF THERE IS TOO MUCH PLAY IN THE STEERING....

Power steering failed and lost engine power. Very dangerous and potentially life threatening event. Unit would not start again for at least 15 minutes. This is the second time this has happened since the dealership was supposed to have fixed by changing out the battery. I reiterate THESE ARE VERY DANGEROUS EVENTS AND COULD CAUSE A FATAL TRAFFIC ACCIDENT.

The contact owns a 2020 Jeep Wrangler. The contact stated while driving at 53 MPH, the vehicle was uncontrollably shaking for about a minute. The contact stated that after the shaking ceased, the contact was able to drive to the destination. The contact also stated that the failure had occurred three times. The vehicle was taken to the dealer where it was diagnosed with a failed steering damper and the steering damper needed to be replaced. The contact was informed that the part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 32,533.

While driving around 44 mph the vehicle started with a death wobble, steering wheel started shaking very hard at the point I almost lost control of the vehicle and crossed the other lane. It’s very scary and dangerous that if another driver is close,we could have an accident.

In September of this year, I would get a random code thrown by the computer, usually telling me that the sway bar disconnected required service, but sometimes it was also the 4wd system. These codes would reset themselves within a few minutes, but I still took it to a dealership for a checkup. The dealership told me that since it currently was not throwing any codes there wasn't really anything they could do. The problem continued to worsen over the next few months. The codes thrown become more varied. I took the vehicle to the dealership two more times and again, no solution was found. Sometimes in the morning when I would go to start the vehicle, it would start, but would not allow the shifter to move, saying that service was required. I took it to the dealerhip again, and no solution could be found. Then the worse started happening. The computer would start throwing several codes at the same time, and then enter a reboot cycle, as I was driving down the freeway. During the reboot cycle, power to the accelerator and power steering would flap on and off, and my ability to steer the vehicle would alternate between powered and unpowered within seconds, leading to a very dangerous situation. The accelerator was the same, disabling my ability to respond to the conditions on the road. I escalated to Jeep's corporate system and left my Jeep at the dealership for two weeks. They were eventually able to identify the CAN BUS as the problem and replace it. I was informed that this was a common problem in Jeep Chrysler vehicles. SInce the replacement of the CAN BUS, I have not experienced any further incidents.

Rear Defroster failed and not covered under warranty even though the problem started while the car was under warranty. Their "fix" was to glue it back on but that didn't fix it. Now my car is out of warranty they won't fix it even though I have extended warranty from them that state that it covers electric window defoggers.

I was on [XXX] when my jeep started shaking violently I pulled over in a rest area. Checked my tires and lug nuts everything seemed fine. Got back on [XXX] and about 5 miles later it happened again. On Friday [XXX] going to holly hill I hit a rough spot and my jeep wrangler shook violently again!! I caller a dodge dealer service department explained what happened and the young man called it a (DEATH WOBBLE) VERY SCARY!!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving, my Jeep's infotainment screen kept flashing an advertisement for SiriusXM Service. I found this obnoxious and distracting because it would display it on my screen every time I came to a stop. And then go away as I started moving again.
