Engine & cooling

I was driving down the road and the car turns off. Everything turns off, no lights, no nothing and it won't crank again. And then I had to call a wrecker truck and the oil was on top of the motor and back of the tailpipe. I couldn't even get it out of the road. I am so thankful my granddaughter was not in there And I'm glad I wasn't on the interstate cuz if I was that would have been bad

The automatic engine stop/start feature failed and engine would not stop running. Had to remove fuse to the electric fuel pump, after about 1 minute engine shutdown. My concern is what if while driving and system fails and engine does shut down , that is a dangerous situation. I know I am reporting that engine would not shut down but if a failure occurs and engine shuts down. System should be anylized. For possible failures.

I started having a problem with my air conditioner. I had to get my car serviced for an oil change and had an AC check. I was told that the reservoir was totally dry and it shouldn't be because it is a sealed system. It should be like the oil & just get dirty. The mechanic said I have to get a ridiculous procedure before they can even tell what the problem is where they add freeone to see what is going on and then take it back out and then I will have additional charges for the actual problem. Just to check is...

almost 500.00. He told me he has been seeing this lately. I wonder if others have experienced this because I understand Chrysler is making jeeps now and I haven't heard anything good. What does it take to constitute a recall?

Service air bag light has been on about 2 weeks. Tried to unlock car with key fob today. 8/6/2024. Wouldn't work so I replaced the fob battery. Nothing will work on car now. Won't start, can't manually unlock back doors.Couldn't get it in neutral to get on flatbed tow truck. Dealership said it'll be at least 2days before they can look at it. Said there's a recall but no remedy/ parts to be able to fix. Now I have no transportation. And they have no loner car to give me. Worked fine yesterday . Been parked in my driveway.

We experienced an electrical failure while driving the Jeep Renegade. We had no power or brakes and multiple warning lights were flashing on the dashboard. Fortunately, we were able to pull into a business parking lot and stopped by running into a snow berm. We could not stop the engine and tried many times to turn the engine off during the 3 hours we waited for a tow truck. We were finally able to turn off the engine and drove it to the local Ford dealership with the tow truck following us. We went to the dealer...

the following morning and the customer service rep started the engine and experienced the same problem. He was unable to stop the engine. He said it could take up to a month for repairs since they only have one Jeep mechanic. I drove it the previous day on a 120 mile trip and traveled on I-75. It could have been deadly if the car failed on that busy Interstate.

Got back to Texas (560 mi.) and contacted 4 dealers in the DFW area. All said there were issues with 9 sp. trans. One said put 2500 mi. on and see if it is a computer break in issue. Took to local dealer with 3300 mi and they did a Star Case. Subsequently, I also went with Manager and confirmed issue. Was contacted by Ralph at Jeep (CASE...

#82736087). Was told car was submitted for buyback. Two days later, buyback was off the table, and I was stuck with it. Jeep said that no problem found per dealership. Called dealership and was told flat out that was not the case. They drove one off the lot and it did just fine (2022 model). Meanwhile, I posted on a Renegade forum and other people are having same issue. We refer to this as "Paid for a 9-speed transmission, but only got 7. This is a safety issue. I drive mostly 75 mph highway roads in Northern Texas using my adaptive cruise and am causing harm by the rpm being much higher than it should be.

1. Checked my oil level at 2,000 miles and it was down by 1/2 quart. I added oil and took to dealer and they checked this out and told me these high compression engine will use oil. No warning signs. 2. Transmission from 1st to 2nd makes noise. Dealer told me this trans is a adaptive trans and if no one else drives this vehicle it will get better. In mornings it is still clunking but after it warms up it gets better. Feel like I'm driving a time bomb.
