Two problems related to check engine light on have been reported for the 2011 Hyundai Tucson. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2011 Hyundai Tucson based on all problems reported for the 2011 Tucson.
My car had unintended deceleration following crank sensor error. On freeway my car suddenly decelerated and I had to exit. Upon exit while diagnosing in the parking lot engine revved suddenly and car moved even though it was on neutral. All the fault codes were caught on torqueobd. However upon restarting the car check engine light is gone and it masks a serious problem in the car that can be life threatening.
I recently reached 115000 miles on my Tucson. It started 2 weeks ago, the alternator needed to be replaced for higher output than it should. It caused the vehicle not to start since it wouldn't hold a charge. Once replaced, the engine light came on again not long after so I took it into a shop. They found that I needed to replace two of the cam shaft sensors. A couple of days ago, drivingmy husband and kids, the rmp gauge went out and the vehicle would not accelerate. Once stopped and restarted, the rpm gauge re-engaged and drive fine. No engine light came on. Driving home today, 66 miles away from home on interstate 78 in new jersey, the rmp gauge went out again. I pulled over on the shoulder, put on my flashers and shut off the vehicle. I waited about 5 minutes and was able to restart the vehicle, this time the check engine light engaged. I was a few miles from my exit, and the rmp gauge again went out, at this point, I was not able to accelerate the vehicle and there were tractor trailers all around me. While reviewing other Hyundai issues, I see other models having similar issues, yet no recall for the Tucson. I am now not only fearful of driving it, engine light or not, but do not have reliable transportation to work.
