2005 Hyundai Tucson: check engine light

Filed May 8, 2021 · Engine, Transmission · 218,900 miles · AZ

Initial issues on vehicle presented in january 2021 with various check engine light codes including p0133. Although vehicle passed emissions in 2020, various check engine codes for mass air flow sensor, oxygen sensors, misfire for various cylinders. After replacing indicated mass air flow sensor, oxygen sensors indicated via obd ii tool, battery, alternator (more than once), both front cv boots, head gasket seals for both cylinder banks, more check engine light issues appear according to the vehicle. Currently another cylinder misfire check engine code has appeared after all spark plugs have been replaced with oem recommended brand replacements (nkg pre-gapped spark plugs). The misfire code has cleared at this time. The current check engine code from the obd ii tool is error code for drive train driveability p0420 regarding catalyst system operating below threshold at bank 1. I have utilized local store catalytic cleaner liquids to clean the system, which has not resolved this issue. Additionally, beginning in january 2021, the vehicle was taken to the closest local dealship for a large majority of these repairs including a $150 dealership fee just to have these codes reviewed and additional fees for the labor to address for each issue for each repair.

I was out of my town picking up a toddler I was going to babysit that night, I also had my own 1.5 year old in the vehicle, on my way back home the vehicles check engine light came on, and the car would not accelerate. We were in heavy traffic going roughly 50 MPH at the time this occurred. I pulled into the nearest gas station turned the vehicle off then started it back up again and the check engine light was off. I pulled out of the gas station and no more than 5 minutes later as I was making a lane change again around 50 MPH the same thing happened and the vehicle quickly decelerated and the car behind me almost hit us! I had to babies in the car under 2 years old! I limped my way to the nearest autozone and the computer read out a misfire in cylinder 5. I lived approximately 15 miles away and had to drive home on the interstate going maybe 40 MPH with my caution lights on while heavy traffic flew by at 70 MPH! I have had my spouse look at it and we have tried several things and the check engine light will come on intermittently reading the misfire in cylinder 5 every time. We are going to try replacing the spark plugs wires and coil pack, but after a ton of research I have little to no faith this will work. I have only owned the car for 4 days and it has 118900 miles on it. I am now nervous to take this vehicle anywhere outside of town let alone on the interstate that run directly through my town!

Misfire cylinder #5. This has been an ongoing problem shortly after my mother gave me the vehicle at apx. 24,000 miles. The car was transported from the east coast here to arizona. It has been in and out of hyundai dealerships and still no fix, with my father paying the bills, which is hard for him being on a fixed income, but my safety as well as his grand children are paramount. The vehicle will quickly slow down from a 70 MPH speed to 35mph without warning and sometimes the engine light will come on (code p0305). I made a complaint once before (case #389816). This continuing problem with no fix has me have several near misses of a rear end collision, which so far I have been lucky not to have. The most recent repair was on june 14th thru 15th, 2013 and the problem was back on the monday after picking the vehicle on sunday, the 16th. When the problem first happened the vehicle was still under the extended service agreement and of course it's now expired will the same problem that wasn't researched during that time. I have seen many comments with owners having the same issues on hyundai's forums, so it's not my imagination. Can someone please investigate these claims so that the problem can be solved? If I could afford a new vehicle it would solve my problem and pass it to someone else, but I don't have the money to do that. Please help, thank you.

Problem with stalling at low speeds I.e - coasting to a stop/pulling into parking spaces. Mechanics do not know what it is since there is no check engine light and does not register any codes. Nervous driving for fear that the engine will stall at higher rates of speed and will lose all power.

Tl*the contact owns a 2005 hyundai tucson. While driving approximately 25 MPH and applying pressure to the brakes, the vehicle stalled without warning and then restarted itself immediately. Three months later, the vehicle stalled again. The dealer stated that they would not inspect the vehicle unless the engine light illuminated on the instrument panel. The failure occurred intermittently. The dealer was unable to duplicate the failure, but stated that the air intake hose was possibly causing the failure. They replaced the band clamps. Soon after the repair, the failure recurred. The contact filed a formal complaint with the manufacturer. The failure mileage was 7,500 and current mileage was 45,000. Updated 06/09/08

Purchased this vehicle in 10/05 and have been very pleased with until recently. Got a card in the mail for a free 34 point inspection from the dealership, and decided on april 5, 2007 to use it. During inspection nothing was brought to my attention. Then this week on may 8, 2007 the check engine"light came on. Took vehicle back to dealer for check. I was advised that some valve was bad and they replaced it, but by the way, you need 4 new tires and an alignment right away. Recently while driving in the rain I had noticed that the vehicle was all over the place, hydroplaning. I felt very unsafe and glanced at my tires. Strange enough, all 4 tires were evenly worn out and near completely bald. Did I mention that I only had 27,000 miles on them ,and I have not been anywhere but regular streets. But not being the tire expert I took the dealership at their word and assumed all was well. So, a bit annoyed on may 8,2007 I decided to look up my warranty paperwork. How ironic! There were two pamphlets for tires in my little handy little hyundai owner's pack. One for these great 60,000 mile good year tires,, and then the other for the hankook, kumho tires that just happened to have only a 24,000 mile warranty, and happened to be the ones that had apparently been put on my car. So, not only losing a customer to a sneaky bait and switch tactic during the sale of the lx model tucson, the dealership and the tire maker put my safety at risk and tried to blame it on a poor alignment. I may be a woman, and one that didn't know a lot about cars, but I did know that if a vehicle was out of alignment all fours tires weren't worn evenly and completely bald after an inspection that took place just a month prior, yet wasn't mentioned . I was still pleased with tuscon, but very angry with dealership tactics.
