What owners say about the engine

Verbatim from NHTSA complaints, newest first
“I have had my transmission in my jeep Wrangler fixed five times it is still barely working. As well as I am having an extremely bad death wobble when I drive, which is very unsafe for me and my son when we are in the vehicle. We have been trying to keep getting it fixed, but it seems like nothing is working. As well as my lights have been going in and out on my dashboard, which is again unsafe during the night. I am afraid for me and my sons safety and we are not wanting to keep driving this vehicle as well it barely passed emissions so I can get my tag for my plates. We are wanting to get something safer for me and my family.”

“All of my wires on the drivers side is unhooked and hanging. All of my emergency light have came on. The car is running hot and not catching up on proper speed. The car wobbles left and right when going over 40mph. My reverse camera is hanging covering my license plate causing m to consistently get pulled over. There are a lot of safety concerns. The dealer used profanity towards me and told me he was not fixing anything, I better use my warranty. I got what I got!”
