2008 Jeep Patriot 4x4: sudden loss of power

Filed Jul 26, 2018 · Fuel system · 68,000 miles · MN

Engine stalls after fueling tank. During acceleration out of gas station, car jerks as it seems the air/fuel ratio is messed up. Car stalls when sitting at light or within a couple miles from the station at idle speed. I've resorted to shifting neutral and revving engine higher to counteract the stall. One instance was knocking/attempting to stall shortly after pulling from gas station, then operated fine on highway, but when exiting the jeep stalled and lost all power to the system (power steering and brake booster). Waited a minute at light, then restarted and ran fine. Dealer informed me that there likely is a problem with the valve to the vapor canister and it sounds like there is liquid fuel getting in. He had a prompt answer for me, so it seems as if he's answered the question before with other owners.

I had just filled the tank as usual and drove about 500 yards to a red light. In the past after a fill up, the jeep would stall and "buck" around 30 MPH, as if it couldn't get into gear, even though this is a CVT. I thought this might happen again, but it didn't this time, which was curious. At the light, upon attempting to accelerate there was no response from the throttle, and the car remained in drive, but refused to move. I could not shift out of gear into neutral. A red light in the upper left corner of the dash came on and began to beep, and the entire dashboard lit up, with every light coming on and making noise. Eventually, I lost all power and waited more than an hour for a tow truck in the middle of a three lane avenue. The mechanic told me a relay was entirely blown and blackened, and this had killed the battery. This was replaced at no cost to me, but he said they could not find what had caused the relay to blow. Essentially, what occurred was a symptom, not the cause, and would happen again. The car is currently sitting, deemed unsafe to drive. I also had lower ball joints replaced at 55,000 miles, which is far too early. I love jeep, but I hate the 2007-2010 patriots. Bad buy.

Over the past year my jeep has been very sluggish, accelerates at higher RPM's than normal, "shifts" rough ( even though it is a CVT and doesn't have gears). For example, when I slow down to make a turn and then proceed to accelerate after the turn, my jeep hesitates to accelerate, the RPM's plummet and then reach to over 3000 RPM's before it slams/jerks into gear to return to around 2000 RPM's. Twice my jeep has shuttered and stalled while at red lights. Last week after backing out of my driveway, as soon as I put it in drive the electronic throttle control light started flashing and dinging at me. My jeep went into "limp mode" and I was not able to travel 8 feet from my driveway. I pulled to the side of the road and attempted to restart my jeep 3 times, and every time I had the same "limp mode"/electronic throttle control issue. The check engine light did not come on at all. The manual states that "if the light is flashing when the engine is running you may experience power loss, an elevated/rough idle, and increased brake pedal effort, and your vehicle may require towing. Immediate service is required.". This does not sound safe. I had it taken to a certified auto mechanic who said it was a throttle body issue and that I would need to have it replaced. However, chrysler/jeep has 1,500-2,000 throttle bodies on back order and I was told it would take several months to even receive the part. I'm glad that my jeep did not stall or go into "limp mode" while traveling on the highway as this could cause a fatal accident. I consider myself lucky, even though I am now making car payments on a vehicle that will not run. This is also my only vehicle. There must be a major issue with the throttle body to have 1,500-2,000 on back order and should be looked into.

Dash lights -- 4wd, ABS, esp and bas lights, skidding car icon -- all come on at same time accompanied by warning chime while braking and turning a corner at low speed, approximately 15 MPH. Engine stalls, loss of power brakes, power steering etc., car stalls in middle of road near intersection ' safety hazard. Will not restart on first try (nothing happens when I turn the key). Starts on second try, then dies. Finally starts and remains running on third try. I have previously had vehicle to authorized jeep dealer and an independent garage. Neither were able to diagnose or repair the defect. This is beginning to happen once or twice a day now and is becoming a real safety problem.
