new Jeep Cherokee shifted into low while on expressway Sign In

My 2016 Jeep Cherokee, 6 cylinder, shifted down into a low gear while I was entering the expressway. I was shuck in traffic for 30 minutes. When the traffic began to move again, I began to accelerate. All of a sudden, the engine got loud and the rpms went up to 7 and 8 on the gauge. I pulled over to the side of the freeway and stopped. I never touched the gear shift, it's an automatic. I put it in park and then put it in Drive again. It went into the regular drive and I took off. My jeep has 854 miles only! The rpm gauge still has a bright orange warning covering the 7 and 8 rpms. I will call the dealership in the morning, but has anyone ever heard of this? I don't know anything about cars really.

Just 854 miles on this! Make a note that this happened in writing on a service check NOW. This should be 100% warranty covered unless something is damaged somehow.


Make sure it's noted that it revved up to 8,000 as that's beyond what engines are designed to do which is why there's a warning area on a gauge for that. Brand new or not that alone can cause real engine damage! Again note that in writing now. Surprised it went that high without a control preventing that? Too new to know,

Hello,

This should be the Zf 8 speed transmission in this jeep, not much info is out there about this transmission, when this happened did the check engine light come on? Gary

I made an appointment this Monday at 7:00 am because I have to be at work at 8 am. They said over the phone it might need a software update. I will make sure they write about the rpms on the ticket. Thank you

No, the check engine light did not come on. It just wouldn't change gears and I knew right away I shouldn't be driving it with it going up to 7 and 8 rpms, so I pulled over right away, being on the expressway with a lot of cars behind me. I have read the Cherokees have transmission problems. I can't believe I am having car problems before the first car payment is due.

Again - my take on this and suggestion is that for any reason was able to rev that high - you shouldn't have to have even been confused by bizarre behavior or later blamed that it was abused if that did do harm is what I would worry about.


It's not even really about cars at all. You paid for new and should expect it to behave as new. Can't be just me but I don't want something brand new all fixed up, or major issues. Being a vehicle they aren't likely to just give you another new one so just make sure it's perfect when settled,
