2020 Jeep Gladiator purchased new experienced violent shaking of the steering wheel and partial loss of control at highway speed on March 10, 2024 with the odometer at 27,500 miles. The shaking is commonly referred to as a "death wobble" incident. While driving at approximately 60mph on the interstate the vehicle became unstable on uneven pavement and began to shake so violently it nearly resulted in an accident and we had to immediately pull off the highway into the median. After a quick inspection no damage was found, the death wobble incident happened again the same day to a lesser degree and vehicle seems to be more unstable each use. Vehicle is available for inspection. The death wobble is so severe enough to cause an accident due to loss of steering control and suspension instability as well as injure the drivers hands and arms due to violent movement of the steering wheel. …
Multiple issues occuring starting (documented) at 22,719 miles (09/27/2022) - stop/start and remote start had not been functioning properly - vehicle died. Required towing to dealer. Both batteries were dead. Upon leaving dealer they had not reconnected stop/start. Fast forward to 05/04/2024 and vehicle once again unchargeable to start. Took warrantied battery back to dealer and they wanted us to tow it there to check. We spent 350.91 to replace ourselves due to a lack of confidence with Jeep. Then on 05/20/2024 took it to a 4x4 center and discovered multiple issues with vehicle from manufacturing and dealer work. To start -- 1) the rear differential pinion seal is leaking 2) the power stearing box is aluminum and showed signs of flex and contact 3) dealer installed lift was incomplete leaving the front axle off center (visually observed about a 3" offset).
While driving the 2020 Jeep Gladiator on highway I experienced extreme vibrations and shaking of the steering wheel (Commonly referred to as the "Death Wobble" in other online complaints/videos). This occurred on at least 8 occasions when traveling at highway speed (65mph to 70mph) after hitting a bump (ex. overpass bridge joint) or rough patch of road (ex. pothole). The steering wheel and whole front end of the vehicle wobble violently and it can only be corrected by reducing speed rapidly. This creates a safety issue as rapidly decelerating to get the vehicle under control on a highway puts my vehicle and the vehicles following me in danger. After reading other complaints, this appears to be an issue with Jeep Wrangler and Jeep Gladiator models going back several years.
my wife and I were driving on a freeway each time this happened. After driving over a bump in the road, the front end vibrated violently to the point we had to slow down drastically and pull over. It controlled okay after slowing down to a very slow speed. This has happened approximately 5 times. We are scared to drive this vehicle. It causes the steering wheel to vibrate. We called the dealership today (Sat.) noone called back but we will call them Mon. This vehicle is too dangerous to drive.It has between 27 and 28 thousand miles. It has never been off road.We bought it new off the lot and will pursue this with the dealer. We wanted to report it before someone is in an accident. It is available for inspection.
Driving down the road the steering gear box will randomly quit, could be doing 70 mph down the expressway and not be able to swerve, turn or avoid an accident. Has happened to me three times. Also the steering free play on these vehicles is absolutely insane and very difficult to keep the vehicle in its lane going down the road. I have been pulled over by police three times for "swerving" and it's all due to the steering wheel having too much free play. This needs to be recalled because it's unsafe to drive
