Dealer completed update 9C2 Theta 2 emissions update. After update, the car sputters slightly and increased noise is heard from the tailpipe. Customer returned to dealer after driving the car in different temps and noted the above complaint. Dealer verified the complaint but continues to take no responsibility for the fault on the repair receipt by writing condition is “normal” and recommending “customer to allow vehicle to properly warm up for one to three minutes prior to driving.” The last line of the service record indicates “no problem found at this time.” A template letter from Hyundai was attached to the repair record. Hyundai may be instructing dealers to not document problems in the service records assumably so they will not be liable for future litigation. It should be noted that owner was previously denied payment on their 2017 Hyundai Tucson due to lack of documentation by the dealer to prove the case with prior class action lawsuit despite years of verbal complaints to the service staff. Dealer may be intentionally not documenting or taking responsibility for systematic failures in the Tucson in service records. This may be on the direction of Hyundai corporate. 2020 Hyundai Tucson continues to sputter periodically during normal driving conditions. Car is parked in an attached garage making a 1 to 3 minute warm-up time-consuming and possibly unsafe. This required warm up should not be considered normal as indicated on the repair record. Hyundai should take responsibility for their shortcomings and allow proper documentation on service records rather than pushing the fault on the owners. As with previous Tucson complaints, the dealer continues to indicate the problems are the result of owner actions not internal failures.

The engine lost power while driving, and the vehicle entered a reduced-power mode. The check engine light began flashing, and the engine made a loud knocking noise during acceleration. A diagnostic scan showed code P1326 (Knock Sensor Signal Range/Performance). The knock sensor was replaced, and the engine oil was refilled after discovering an oil leak. The vehicle operated normally for a short time, but the same symptoms returned. The vehicle is available for inspection. The vehicle suddenly lost power while traveling approximately 70 mph on the highway, making it difficult to maintain speed and safely keep up with traffic. This created a risk of being struck by other vehicles or causing an accident. The problem has since recurred during normal driving. The problem has been reproduced multiple times. A diagnostic scanner consistently identified code P1326. The knock sensor was replaced and the engine oil was replenished, but the same symptoms returned after several trips. The vehicle has not yet been inspected by a Hyundai dealership. The vehicle has been inspected by the owner and a family mechanic who replaced the knock sensor and identified an engine oil leak. It has not yet been inspected by Hyundai, law enforcement, or an insurance representative. There were no warning lights or messages indicating low engine oil or an oil leak before the failure occurred. I had the engine oil changed approximately one month before the incident. While driving on the highway at approximately 70 mph, the vehicle suddenly lost power, the check engine light began flashing, and the engine started making a loud knocking noise. After inspecting the vehicle, we discovered it had an engine oil leak and the oil level was low. Before the loss of power, there were no warning signs that the engine was losing oil or that there was an oil leak.

Tried passing someone on the thruway, as I was about to the car jerked a bit then started decelerating. The check engine light started flashing and so did the oil light. Read the code as cylinder 3 misfire and a knock sensor. Changed the spark plugs and coil packs then checked the oil and saw there was no oil in the engine. Was told by my mechanic it’s a common problem with these Hyundai engines, it seems the rings are getting fried in the engine and that’s why it consumes oil so quickly.

Was in a side impact car accident last year. And have been speaking with Hyundai off and on since the accident and have basically been brushed off in my concerns about the fact my airbags never deployed when my rear passenger door was essentially ripped off during the car accident. Progressive moved quickly with my claim and Hyundai pretty much told me not their problem since progressive moved the vehicle so fast and they said they can’t locate it even though I gave them exactly who to get in contact with and they never bothered and basically told me my issue was unfounded due to the fact they couldn’t locate said vehicle

Vehicle is a 2020 Hyundai Tucson with a 2.4 liter engine: Theta II GDI. Vehicle was purchased new and maintained properly. Excessive oil consumption began at about 50,000 miles. Vehicle was purchased in early 2020 and therefore has an engine manufactured in 2019. Tucson vehicles with this engine from 2011 through 2019 were recalled for engine problems including excessive oil consumption and rod bearing failure possibly resulting in engine fires. If engines were not replaced an extended warranty was given for 150,000 miles or 15 years. Hyundai will not remedy our excess oil consumption problem locally or nationally. An oil consumption test was done at the Hyundai dealer. Conclusion: by dealer and national level office: it's not bad enough to remedy. There were no engine warning lights activated because we check the oil regularly and add as needed. This post-2019 2.4 liter engine continues to be a hazard as some owners from previous year's models had engine seizures in traffic which is dangerous. Some owners reported engine fires. We have not experienced those tragedies but possibly post-2019 Tucson owners should be alerted to potential dangers.

While driving on the expressway my car hit a bump and all the power from the vehicle was lost. I’ve been having issues with my car and have taking it to Hyundai dealership. Everytime I take it they are saying my car is fixed. But it’s not. Now they are saying they didn’t fix it because I didn’t explain the problem to them. I lost control driving high speeds. Thankfully the power returned. When I tell hyuandai in Naperville what happened they said it’s not their responsibility because I didn’t say it was electrical. I told them I didn’t know I had a an electrical problem. I thought that if I take my car in they would tell me the problem.
