2018 Hyundai Tucson: won't start

Filed Jan 28, 2026 · Engine · MI

My 2018 Hyundai Tucson experienced repeated no-start conditions. The vehicle was initially diagnosed by Randy Wise Hyundai in Flint, Michigan, and I paid approximately $776 for tune-up services that did not resolve the issue. Shortly afterward, the vehicle continued to fail to start. The dealership later determined the starter had failed and provided an estimate of approximately $985 for replacement. Hyundai Motor America denied goodwill assistance and reimbursement for the prior misdiagnosed repair and stated the starter replacement is customer-pay. The vehicle’s inability to start caused loss of reliable transportation and safety concerns due to being stranded. I am submitting this complaint to document starter failure and potential diagnostic issues affecting vehicle safety.

The oil plug fell out of my Tuscon while I driving on the highway and it burned out my entire engine on January 2, 2023, at approximately 5:40 pm EST. The tech at the dealership found the plug in the tray under the spot where the plug goes. It was inspected by a technician at a Hyundai dealership. The car is a 2018 Tuscon--had less than 55,000 miles on it and is now basically worthless and undrivable, quoted $13,000 to fix it. My entire engine now needs to be replaced. I was within the lifespan of my last oil change when the plug fell out. A red oil light flickered on and then a battery subsequently came on. Within approximately three minutes of the light first flickering on, the car was dead on the side of the highway. The car would not turn over once it was stopped on the side of the highway. The car is still at the dealership and available for inspection as of today, but I am not sure how long it will be there because I am not sure what is the best path forward in terms of repair because of the financial cost. I'm lucky that I was able to navigate my car onto the shoulder of the highway and secure a tow without injury. It was a very foggy day and it was already dark when this occurred and I was afraid I would be struck if I exited my car. My car drifted to a stop at the start of an exit ramp with a highway barrier that prevented me from going farther right onto the shoulder.

I bought my 2018 tuscon one year ago in June 2020. 70,000 miles on it now, regular maintenance. No warning lights, everything was running OK. I started experiencing hesitation taking off then lunging when stopped in the last few months. Now I'm sitting in the driveway because it won't start. Realized oil was low which is odd because I've noticed it's been burning more than previous but no more than a quart so it's not like it was dry. I'm supposed to be able to get 5k on an oil change now adays but starts running poorly if it's not changed by 3k. Needless to say iadded qt of oil I was going to get oil changed yesterday but wouldn't start. I changed the battery, still won't start, starter was tested good, fuses all in tack, changed camshaft sensors at 90 dollars a piece still nothing. Check alternator that's fine. It clicks one time but have all lights power everywhere it should. In 2 days I've spent 215 on a battery, 200 with tax on sensors, 50 code reader no code by the way. Did have p0014 which indicated need for either oil change or camshaft sensor. Nothing. I'm a sitting duck and all the things I've experience are what they experienced in the theta engines like hesitated, burning oil, ticking sounds, lunging etc. GDI isn't any better. I hate this car. After this one is paid off and I guess put a new engine in I'll be getting rid of it. Going back to a solid Buick. I'll never buy another hyundai. This is the second vehicle with engine problems we bought. Not to mention the risk of for but hyundai near me hasn't been able to get the parts for over a year. I'm currently in a wait list.

I have a 2018 hyundai tucson and it cut off on me while returning home from out of town on 4/5/2020 on 495 capital beltway. White smoke started coming out the tailpipe so I pulled over and cut the truck off, I tried to restart and it wouldn't turn over, all of the dash lights lit up, I had to call aaa to tow me home, the tow driver noticed oil under the truck and even after he towed me and put my truck on the street there was oil on his flatbed. This truck has a default with the oil plug or something, I keep up on my oil changes every 3 months, there was no warning on the dash about low oil or anything before it started smoking. Something is wrong with how this truck burns oil and it needs to be investigated. Now I have a truck sitting that I can;t drive and still have to pay a car note on.
