NHTSA Complaint #11567587 — 2022 JEEP CHEROKEE

Your website has some trouble & won't accept my jpg files. First time to see this. I use cruise control all the time on 3 vehicles I own. But, this JEEP has a strange problem that is not safe. Almost all vehicles I have driven with cruise controls will exceed set speed by 1~3mph while going down a steep hill. But my JEEP will exceed by 5~7mph on steep hills. I have turned off cruise control when it didn't control speed and drove manually for a while, then used cruise control again. If I set at 70mph, often speed will increase to 75~77mph going downhill; then brakes will engage strongly (hard braking) and JEEP will quickly go below 70 mph. JEEP will brake hard, go to or below 70mph then speed up some then brake hard again! Two-three times I had 18 wheelers behind me going down steep hill when I was using cruise control, JEEP quickly reached 75~77mph, then suddenly brakes clamped down with a lot of force and big trucks had to hit their brakes hard and were not far from my rear bumper. I do watch in rear view mirror often when driving. There are a lot of hills in my area of East Texas. I also watch out for smaller vehicles also when I use cruise control, especially going downhill. I took JEEP to a dealer Jan. 24, 2024 in Palestine, TX 75801 to check excessive carbon SOOT in tailpipes, coming out of muffler. And, I told service Mgr. about bad cruise control braking. They did nothing. Now, see Elliott JEEP dealer Service Invoice [XXX]. Dealer wasn't interested in looking a cruise control problem. He checked only excessive soot problem and maybe did a multipoint inspection. Also, this JEEP couldn't possible pass an EPA emissions control. I THINK THERE ARE SOME REAL DEFECTS IN MAIN CONTROL MODULE!!!! DEFECTIVE SPEED OR CRUISE CONTROL. DEFECTIVE AIR/FUEL SENSOR CONTROL MAKING A LOT OF SOOT. DISPLAY DEFECTIVE FOR GASOLINE & TEMPERATURE GUAGES IN DISPLAY. In 2023, I told different dealer about cruise control trouble and he didn't check anything, either.
