Filed Jan 25, 2020 · Driver assistance, Electrical · FL

Right after I bought the jeep I started having problems but when I called the owner he said its a buy as is, no warranty, he didn't offer to help with anything and being disabled I had no other choice but to get engine fixed, transmission, clutch, the entire electric system, no AC, no heat or defrost either all these things I fixed but now again in 2020 I still have no heat, no defrost, jeep is in yard not running and I still owe right at 900 on the jeep, the owner has been very rude, made threats, and now not taking my final 3 pymts on jeep, never been late, ever!!!! He runs a shady buy here pay here lot and I have a top mechanic that left his business to vouch for the odometer tampering as well as having the mechanic to fix all the lights on panel that showed engine running hot, he told the mechanic to fix it or he was not getting his pay check, I have the mechanics statement and he will testify in person. I have several employees that have since quite to vouch he sold lemons, and salvaged cars. He lost his dmv license but still continues to fraud people.

When cold, jeep starts and runs fine. After engine warms up, oil pressure would drop and jeep would almost die. If I shut it off and try to restart while still warm, jeep would have a hard time starting and if it did start, it would idle extremely rough and barely accelerate. Once I got speed up, it ran fine until I stopped at a red light and it would act like it was going to die and the oil pressure gauge would bottom out. Dealer put manual gauges on it and determined it was the oil sending unit. Oil pressure now holds at 20 when at idle. The issue with the rough idle and loss of power still persists after the engine warms up. After reading all of the complaints, this seems to be a recurring issue with this model. Really don't want to waste money trying to guess at what is the issue. As many people that there are having similar issues, jeep should stand behind their product and issue a recall. Very disappointed.

1997 jeep wrangler exhaust manifold. Consistent decrease in power, stumbling, and poor gas mileage. After a wreck I noticed the manifold was cracked. Both the insurance company and the authorized jeep dealership told me it was not due to the wreck but due to fact it was a common wrangler problem, and it probably had started prior to the wreck I just hadn't noticed it. But since there is not a recall they would not fix the problem. I have fixed it.

Jeep suddenly lost power on highways while going 55 MPH +., causing a near accident while trying to coast through lanes of traffic to the median. After 10-15 minutes, I restarted the jeep and it ran fine, but usually about 20-50 miles, it will occur again.. Very hazardous.

Catalytic converter failure causing poor performance, excessive fuel consumption and noxious odors. Replacement of converter remedied all the problems.

Same as everyone else....cracked exhaust manifold on 4.0 l 6 cyl. Jeep has redesigned part. I formerly worked with a 4x4 repair shop, and almost everyone that came in with a 1997-2000 (or so) jeep had same cracks. Leading 4x4 magazines state "it's not if it cracks, it's when". Given this many complaints, jeep should be paying to fix their flaw, not consumers. Will replace with aftermarket component, not jeep's.

I am in the process of replacing the exhaust manifold on my 1997 jeep wrangler for the second time. The first one failed at approx 55k miles (out of warranty) and chrysler jeep customer service denied existence of a problem with the exhaust system, in spite of numerous reports of manifold failure on many internet automotive sites. The replacement part was supposedly redesigned to prevent recurrence of the problem, but it has now failed (mileage is now 110k, so these are 55k parts!) and must also be replaced. The mechanic stated that the replacement parts just crack in a "new spot". Chrysler jeep has been totally unresponsive to what is obviously an engineering flaw in their product, and sticking their customers with the bill and any resulting safety issues! Not a great way to build your customer base!

My vehicle has run rough, idling rough, "bucking", losing coolant and dripping from the tailpipe about a week after the extended warranty expired. I have had major valve train problems and had to have the camshaft replaced along with the gasket, cylinder head, core return, radiator and now the latest is oil pressure gauge sending unit. Oil pressure still showing zero even after replacing sending unit!
