I had 4 new tires put on my 2013 Hyundai Sonata (previous Hertz Rental Car) about 1 1/2 weeks ago. Yesterday & today I had all 4 TPM'S replaced. Why won't the TPM light stay "cleared?" I bought this car in early 2015 w/58K miles on it. I am at about 107K miles. Have not had any problems with it till now....but, it's ANNOYING. Most importantly, if there is a problem....I won't know it? Also, I have put a full size tire/rim in the trunk....could that make a difference? Should I put the temporary tire back in there?? 2 Answers

I have also changed out the stock rims on it, however, didn't have any problems with those rims prior to having the tires put on last week. Not sure how to proceed from here.

2011 Hyundai Sonata--I changed my battery on Saturday morning and the ck engine light came on. I followed the instructions in the forum and disc the cables for 1/2 hour then connected the negative cable first then the positive. Light went out than came back on. Went to Autozone and had them run a scan that showed P0106 MAP sensor fault so I replaced the sensor with a brand new one $81.00 and the light was still on. Again I disc the cables and the ck engine light turned off but again turned on. Drove close to 75 miles and still on. I went back to Autozone this morning and when they attached the code reader the light turned off. I drove less than 1/4 mile and it is on again. PLEASE HELP! 2 Answers
