What 181 owners told NHTSA about the 2011 Hyundai Santa Fe Hybrid Hev

My 2011 Hyundai Santa Fe (approx. 153,000 miles) developed a new stalling and engine-dying-at-idle condition immediately following a knock sensor replacement performed by a Hyundai dealership. Prior to this repair, the vehicle ran normally with no stalling or idle issues. The vehicle was originally brought in for diagnosis related to code P1326, which is covered under Hyundai Service Campaign T6G (engine rod bearing / knock sensor campaign). The dealership replaced the knock sensor but subsequently claimed my vehicle's P1326 condition did not qualify under Campaign T6G. Immediately after the knock sensor replacement, the vehicle began stalling and completely shutting off at idle — a condition that did not exist before the dealer's service. I returned the vehicle to the dealership to address this new issue. The vehicle has now been at the dealership for over three (3) weeks with no diagnosis update, no repair timeline, and no communication from the service department. I am filing this complaint for two reasons: 1. Safety concern: An engine that stalls and dies at idle presents a serious risk of loss of vehicle control, particularly in traffic or at intersections. 2. Service Campaign T6G: I believe the underlying condition and the dealer-caused stalling issue are both connected to the knock sensor system covered by this campaign. I request that NHTSA review whether this vehicle qualifies under Campaign T6G and whether dealer-caused damage following campaign-related service should be addressed under the campaign or a related recall. The dealership's failure to communicate for 3+ weeks and their claim that my vehicle is not covered under Campaign T6G warrants regulatory review.

I was driving the car on a 4 lane road when suddenly the engine shut off and the car was no longer functioning. I lost power steering and had to coast into a nearby parking lot, otherwise I would have caused a major accident in the middle of a busy intersection with another 4 lane road. Upon taking the car to Hyundai for evaluation, it was declared to be total engine failure. Given the other issues with Hyundai engines failing and the fact that I VERY NARROWLY AVOIDED A MASSIVE COLLISION, I would like NHTSA to be aware that this problem may go back farther than Hyundai has addressed so far.

I pulled up into my grandma's driveway, put the car in park. The car continued moving forward and when I depressed the brake pedal, the car accelerated for some unknown reason. So I put both feet on the brake and it still continued to accelerate. My car crashed into my grandparents garage door, then into their car, then pushed their car into their washer and dryer, causing those appliances to push against the wall, breaking the structure, busting water lines, smashing the washer and causing damage.

I read the recall on vehicles of my type and it sounds like the issues I have been experiencing. I’m thinking the car was recalled and repaired ineffectively before I got it. The brake fluid is leaking with no obvious fix, I’ve taken it to a few mechanics to check.

My 2011 Hyundai Santa Fe had 75,000 miles on it in September 2022. It was bought and serviced by the same dealership and I am the original owner. It was last serviced at the end of June 2022. While returning from Corvallis, Oregon to Forest Grove, Oregon, the car's display light all turned on and a second late the car completely stopped. I am thankful that I decided to take the back road home, if I had been on the highway, I am positive I would have been in a serious accident. It has been determined by the dealership that there was a complete engine failure. It has been at the Hyundai dealership for four months now and there is no replacement engine available for it. Not only that, they can't get a reasonably priced replacement engine anywhere. This car would have been a valuable trade in on a new car. The Diagnosis was Engine crankshaft seized. Metal particles on Dipstick, large metal fragments on oil filter, Engine replacement required. The car is now worthless, expect for parts.

The brakes on this Santa Fe have produced some unexplainable issues? A complete brake job was done approximately six months ago by a reputable brake shop because of similar issues with the brakes that occurred again last week and yesterday. Additionally, all fluids were normal during routine oil change and fluid check on Aug 13th. Last week while backing up the normal brake would not stop the vehicle and the car was stopped by using the emergency brake. On Oct 4, 2021 the brakes did not work causing the Santa Fe to "rear-end" another car at a red light. Speed was approximately 35-40 mph. Air bag deployed and no one was seriously hurt in the accident. Problem has not been reproduced or confirmed by a dealer; just a complete brake job 6 months ago by a brake shop. Vehicle is now at the tow facility awaiting the inspection by insurance company and can be inspected by anyone interested in doing so. There were no warning lamps or messages of the problem prior to failure. Additionally, this car's blinkers have randomly stopped working with no notice and just randomly started working again after a period of time. Emergency flashers worked but not the normal blinkers during this malfunction. This vehicle definitely has some Gremlins!! It's unknown why this model Santa Fe has produced a similar problems as other Santa Fe's with no recalls on this particular model or VIN # ?
