Two problems related to crankshaft position sensor have been reported for the 2011 Jeep Grand Cherokee. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2011 Jeep Grand Cherokee based on all problems reported for the 2011 Grand Cherokee.
Vehicle lost power while driving at speeds of 55mph. Check engine light and multiple system warnings were shown by evic, including abs, traction control, ignition system, 4wd system, and air suspension system. Braking power was severely diminished. Maximum speed was reduced to 5mph, before stalling out after 10 feet. The cause of the issue was a short in the crankshaft position sensor that disabled all powertrain and braking systems. All systems share the same 5 volt circuit into pcm.
Vehicle cranking long before starting, dealer diagnostic was tipm, Jeep was contacted they agreed they has issues with part mentioned and agreed in provide part w/$100 deductible, I still paid for the cranking sensor and labor, new tipm created more electrical problems. When turning signal was activated fog lights were blinking but not the turning lights, taken back to dealer they temporary fix the problem until Jeep releases the new update in at least 2 months, after they fixed the turning lights another issued resulted, now the stop tail brake lights don't turn on if ignition switch is not in on position and sometimes even with the engine running , or if engine is not running. This issue concerns me a lot, since this is very critical if driving on highway and engine stop working how I will let the vehicles behind me that I have an emergency and I'm stepping on the brakes,lights will not turn on. Are you people from NHTSA waiting until fatalities happen to force Jeep to make a recall and fix the problems. ? there are thousands of vehicles with failures related to this tipm , please prevent people die in crashes for this issue and do something about it. Now my car is in the dealer again because they can properly fix it, and all related to this new tipm. These corporation was already bailout with our tax money, now they are passing the cost of repairs to people who purchased a defective product, it is very suspicious that all of the tipm went bad, between 50,000 and 60,000 miles just after warranty has expired. . . Please do something.
