I purchased a 2005 chrysler pacifica in michigan in 2006 and imported into canada. The vehicle has 31,000 miles on it and the engine is burning oil rapidly. I noticed a noise coming from the engine and found the oil level to virtually not appear on the dipstick. The check oil light never came on. This could have LED to the failure of my motor while I was driving. I have also had a cylinder misfire and spark plugs replaced due to this.

The engine light on the dashboard lit up one day. Shortly thereafter, I experienced a very rough idle. It did not stall however, but continued to idle and run very roughly. Upon examination, the dealers service department determined that the tsb #09-010-06 had described the issue and it's recommended fix was applied. That being to replace the valve spring retainer locks, combustion clean, and replace and test the map sensor. This tsb fix had the adverse effect of causing the engine to surge rather abruptly when starting cold, and applying light pressure on the accelerator. It's more noticeable when backing out of a parking space and having the wheel turned at the same time. It seems that having the steering wheel turned presents an additional load on the engine that the computer senses as a need for additional engine speed. This surging also happens when pulling forward into a parking space with the wheels sharply turned as well. Three subsequent visits to the dealer yielded different answers without being able to fix it. On one visit, the service director, called to tell me that he had been in contact with chrysler engineers in michigan about the issue and would like to try a couple of things. Namely to check the fuel pressure, adaptive memory, and map sensor. After a test drive he conceded that the problem remained, but not to the degree that I was complaining about. He offered no other alternative fixes, but said that he would remain in contact with the chrysler engineering website that issues tsb's etc. I guess that is supposed to satisfy me as he states that he has done everything he could. As this is unacceptable to me, I felt prompted to file a complaint on the website as I feel that the surging problem is a definite safety issue that needs to be addressed. My next step is the write chrysler directly per their warranty information booklet.

Check engine light at approximately 40,000 miles. The check light has come on the vehicle indicating cylinder three misfired. I have taken vehicle to the shop the first time and had the coil replaced. The same light came on with the same warning. This time the spark plugs were replaced, the injections cleaned out, the throttle body cleaned out. I just got it back yesterday and I feel confident that I will have the same thing over the next few days. When this happens, the vehicle idles rough and the car has no power. This vehicle has been maintained higher than the standards call for in the manual. Looks like chrysler is good for about 40,000 miles, then be prepared to spend some money. I plan to trade the vehicle for a toyota, though I had supported american made vehicles in the past, with a product like this, you can't afford to. The total cost thus far has been $600.00. It appears that chrsyler knows the problem exists because of the bulletins, yet they will not recall the car ,and do what is right for the consumers. People can't afford to pay for a vehicle and repair it at the same time with so few miles. The pacifica is a great riding car ,and I otherwise thoroughly enjoyed it.

Since of october of 2005 my chrysler pacifica 2005 touring has stalled numerous times. One particular incident I remember is when I was make a permissible u-turn and the vehicle stalled. Fortunately for me there was not on-coming traffic and I placed the vehicle in park and restarted the ignition. The stall issues complete power failure in the vehicle. The engine is very loud at low speeds and idles. Currently the fuel gauge is reading incorrectly. According to epa estimates miles on a tank is 393 miles, the gauge reads 301-312. Also, the vehicle around november started to experience difficult cold starts. Initially I attributed that to cold weather, however the problem has become persistent. The was an accident in january 2006 with my wife at the wheel but I has yet to be determined if it was due to vehicular or driver error. While I am not a professional auto mechanic or ase certified, my opinion is that this is an issue with the vehicles intake and possibly a misfire of the pistons. I have submitted the vehicle to a chrysler facility for

Purchased an 2005 pacifica june 10th. Was back in the service department 3 days after purchase with check engine light on. Service supposedly repaired problem but after 1 week noticed vehicle misfiring and check engine light back on. Took it back service replaced a part (not sure what) and reset light. As of today this makes my 4th trip to service department with same problem. Check engine light. The mechanic said today it failed the emissions test and he can't figure out why. I left it there and took a rental, but now it kind of feels like I have bought a problem. (check engine light).
