Post Catalyst Fuel Trim System Too Rich

…The vehicle was taken to the dealer, who retrieved diagnostic trouble codes: P00C6, P0137, P0171, P0299, P089, and P2097. The contact was informed that the codes were associated with the fuel system failure. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 65,000.

WE GOT A CHECK ENGINE LIGHT ON. CHECKED FOR CODES AND P2097 CAME UP. VEHICLE HAS SOME HESITATION WHEN ACCELERATING.

Exhaust bracket broke, created a hole in pipe, which then resulted in cracked catalytic converter. Dealership and GM denied repairs due to the hole being on the "wrong pipe" but the same bracket that is covered broke resulting in the consequential damage. Check engine light came on, loud exhaust noise. Threw codes P219A, P2097, P0171. Bulletin even outlines that broken bracket/hole can cause cracks in converter, still denied. This is a known issue with the welding on this pipe/bracket, why they didn't extend the coverage to BOTH pipes is beyond me.

Vehicle has had a hard shift since 15000 miles, always told at dealership it was normal. At 87493 my check engine light came on and code P2097-00- I was told it was that I had a bad battery and GM would not provide me one. Light was reset. Now at 98000 miles, shifting harder (automatic) like a jolt and vibrates going up hill- told I needed transmission fluid changed, this did nothing. This was confirmed by dealership prior to fluid change and then the dealership would not set up another appointment. Had this confirmed also by an independent service center. Occasionally a light will come on to say shift into park, despite being in park. No other messages related to this.

On [XXX], my wife was driving down the highway and vehicle started to "buck" and almost stalled out. Check engine light came. She was able to make it to the dealer. Dealer ran the diagnostics and received the P0032, P0171, P2097 and P0300 codes. The dealer found the attached document with basically no repair available. We contacted Jeep customer service and were told that it needs a software update, however, they did not know when it would be available. I was not satisfied with that answer and the case was transferred to Jeep retention. In the meantime, we picked up our Jeep and was advised by the service advisor that this is a known issue and advised us to keep the Star publication in the…

While driving 60 MPH on the highway my car started stuttering then lost all power. It threw 3 codes P0131, P2097 and P0171. I have spent over $1,000.00 and a month later they tell me it was my intake bolts that were loose. They replaced every part PCV valve, MAF sensor, O2 sensor and car still wouldn't run right. PLEASE address this issue as that is UNSAFE for a car to just stop on the highway.
