Two problems related to wiring have been reported for the 2017 Hyundai Tucson. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2017 Hyundai Tucson based on all problems reported for the 2017 Tucson.
I purchased 2017 Tucson brand new at roughly 22k my engine seized and the 3rd connecting rod failed. After engine replacement I continued to have problems with rear driver side brake light continuously going out, bulb is not out but wiring scorched and bulb somehow continuously becomes loose. I have replaced front headlights repeatedly with the driver front shattering in housing. I have also replaced calipers and have gone through 7 sets of rotors. At roughly 60000 I noticed I was running out of oil in between every 3000 mile oil change. Continued to bring back to dealer for repair s . I have complained multiple times about hesitation when pulling out from stop and engine knocking. Multiple oil pan reseal gaskets replaced fuel pump replaced, oil always all over engine. At 110k my engine failed a second time with Hyundai denying all claims. Originally said they would reimburse me for rental but when they emailed me letter for �goodwill � reimbursement it was a release from liability waiver if I took their �goodwill � . I have informed them of electric issues and how I feel unsafe with new recall and fire possibility and they informed me as long as no warning light is on it should not be an issue. I tried to trade vehicle in and no one would take my trade, it's 3 years old and worth nothing. Hyundai response was vehicles don't hold their value like they used to. I am disgusted with their dismissive customer care, 2 engines in a vehicle 3 years old and they insist there is nothing wrong with their product.
My car was parked in my driveway. I only had it less than a month (new). I tried to remote start it & it wouldnt work. I went outside to start it & it wouldn't turn over, all lights on dash were lit up. I lifted my hood- a squirrel nest was built under hood. Wiring harness chewed up, insulation under my hood ripped off, numerous areas of hard plastic covering my headlight under hood and along inside frame of car all chewed up. All things chewed were made of soy based materials. I had my car towed to my mechanic, not Hyundai due to the fact that they don't accept responsibility. I had similar problems (3x) w/my Honda 2014 crv that's why I got rid of it. I was told by both Honda & Hyundai "its not covered, it's not a manufacturing defect, it's caused by outside circumstances/ rodents. Use your auto insurance". This is a manufacturing defect because they use soy which attracts these rodents. Soy wiring harnesses should be banned and recalls instituted to remedy the problem by either replacing the harnesses with standard synthetic non-edible polymers as appropriate to the specific application, or providing coatings that provably prevent rodents from consuming the insulation over the lifespan of the vehicle. I can't even park in my own driveway for fear of more damage that I have to pay for due to the use of soy. This problem is all over the internet caused by soy used by various car makers. Please do something about this ASAP.
