While driving at high speeds car jerks and removes itself from cruise control and RPM gauge drops to zero and stays there (has occurred without cruise control being on as well). When the car slows down to 30 mph or less, or while sitting at a red light, it shakes violently. Has occurred multiple times w/O personal mechanic being able to diagnose problem. One time, the check engine light came on and error code P0605 was identified. Battery was changed and check engine light went away, however, the violent jerking occurred later that same day exhibiting all the same issues as previous occurrences.

5 year old Tucson with only 75,000 miles experiencing rod knock and requiring an entire engine replacement. I have not had a single issue with this car and have kept up on regular maintenance. The dealership says that I do not qualify for the power train warranty becuse I am the second owner. After much research I see this is a recurrent problem with Hyundai Tucson's as well other models in their line up. No recall or solution to the problem has been brought forward. My car started knocking while on a major highway with cars going 75mph. I luckily got it off an exit and did not cause an accident involving the cars behind me.

I religiously maintained maintenance on my SUV, but out the blue, last weekend 7/29-30 I was at a light and the check engine light appeared and something broke in the engine area, I heard a snap, it sounded like a belt. Well, I flat bed towed the vehicle to the dealership and to my amazement, I received a call from the service advisor that I needed a new engine" the cost would be around $8,000. I religiously had every warranty service done and they came back with my crank shank pins and pistons were worn out and rod knocking was taken place, plus no more rod bearings. I asked what could of caused this and he stated, "lack of oil?". I never missed an oil change on the SUV, so how could this be?" also, metal shavings were found in the oil pain and cylinder 2 and 3 gone. There was a recall on the Santa Fe SUV 2011-2013, Kia 2011-2014 whereby the same thing crankpins, metal shavings found, the exact wording from the class action lawsuit (found online) is "during machining of the entire engine, crankshaft and crankpins, metal shavings may have been left within the crankshaft oil passages, oil may be blocked and cause the connecting rods to wear, which would then cause hem to fail and seize the engine. Now, they didn't list my vehicle, but it's the exact and should be investigated since my vehicle has the same engine! also, this occurred at exactly 100,000 miles when the warranty expired. Now, the service advisors are being horrid and heated exchanges are going on with the car dealership team on my car repair. It's still sitting at the dealership and I'm in an expensive rental. I had just made my last payment....

Since purchasing the vehicle in 2013, the serpentine belt has shredded on multiple occasions while driving at speeds of 50-70 mph. The serpentine belt has been replaced 5 times due to a continuous oil leak saturating the belt over each period of 6-9 months, water pump pulley defect and the alternator seizing after it was replaced 90 days prior. The car was in motion on city streets. Each time the belt shredded, the vehicle required a tow truck (twice)

When entering an attended automatic car wash, I placed the car in neutral, foot off the brake, as instructed by attendant. The car continued to move forward, slowly and tapped the car in front. They stopped the car wash and said the car had been in gear. However, it was in neutral. When they restarted the car wash, my car continued to creep forward, with my having to tap the brake repeatedly to maintain a safe distance from vehicle in front. Later that day I checked this on a level surface in a parking lot. When the car was placed in neutral with the engine running, and foot off the brake, it would creep forward at a slow walk speed. When it was in neutral with the engine turned off, and foot off brake, the car would not move. It appears that the transmission is engaging to some degree even when in neutral. This constitutes a hazard since the car may move in situation like a car wash or other circumstance where it is placed in neutral with brake off and engine running. On the day after this incident, I recorded a video documenting this issue.

Car has been in shop about 8 time for pulling to right 1st they said it was bad tires switched out but still continued to pull went it shop again said it was the tires so switched out again took another dealer said that it was the crowning in road I drove other Tucson's and they did not pull then they said it was because of all the mileage that was on my car next they said it was pulling bc of electronic steering id really like to know what is wrong with the car. I have a regional person coming down on the 28th of Aug to look into car pulling to right. Also have took my car to firestones and they say that there is something definitely wrong with the tow and alignment yet the dealer insists that is not the problem.
