general problems of the 2006 Kia Motor Sportage

I purchased this vehicle from a private seller in August 2021 and attempted to obtain records of the vehicle kia America case id #14353653 which kia America has yet to provide me any information. I had a full diagnostic done by a certified mechanic at borst automotive in the state of arizona on 09/18/21 where several concerns were reported to me that kia failed to report. There is a new and concerning grinding with the engine on my 2006 kia Sportage lx that sounds like it might be an exhaust leak. I hear loud grinding sounds now when turning on the car that immediately sound when it is fired up, and when accelerating is the worst, but the sound starts loud and is immediate when I turn on the vehicle and fire up the engine. Two days ago on 10-01-21 which was the last night I drove it as it feels unsafe to drive now, I did not get far before the front driver's tire closest to the engine completely blew out/ and exploded coming off of it's wheel and cap hinting at a potential engine problem or recalled defect. I had to immediately pull over and call aaa to come put the spare donut on my car to get it back home to park. The engine appears to have something wrong with the exhaust system and it sounds bad. I reported this today to kia America case id #14407655. I always make it a point to to check fluids and something is not right here. The car is overheated but radiator is fine and coolant, and all other engine fluids are full but could be an engine issue that is dangerous. This engine sounds like it will burst at any minute its grinding and stalling so bad. Made an appointment with royal kia in my hometown tucson, az for October 12, 2021 to have the fuel tank straps replaced as apparently they are faulty and this was the soonest this dealership could perform this. I know the 2010-2021 Sportage models were recalled under safety recall 20v-750 but since this recall is somewhat new and yet to discover other kia Sportage’s that might also be affected.

Previously reported engine surges / erratic idle at 177800 miles, and throttle body cleaned at 177900 miles. At 178345 the idle air control valve was cleaned as a precaution, due to the previous symptoms. At 178377 while driving on the highway I found the throttle stuck in the full open position. After safely stopping the vehicle, I had to manually return the throttle to the normal position. Upon restarting the vehicle I began experiencing erratic idling 3000 to 4000 rpm. Once parked at 178382 the idle air control valve was rechecked, and engine idle rpm returned to normal. I checked the obdii and found no previous or pending codes. I will replace the idle air control valve.

I previously reported at 177,800 miles that I was experiencing engine surges. While driving if I depressed the clutch engine would rise to 2000 rpms. If I pulled the accelerator pedal up with tip of my foot, the engine rpms would return normal. At 177, 900 miles the throttle body assembly was cleaned, and I am no longer experiencing engine surges.

While braking the vehicle appeared to be picking up speed. When I depressed the clutch the engine surged past 2000 rpm. While driving on a downgrade the vehicle was picking up speed, and I depressed the clutch and the engine rpm went 2000 rpm for several seconds. From my experiences with other vehicles I thought: maybe the driver's mat shifted, or some other object may have fallen and was interfering with the accelerator pedal. I felt around the pedal with my foot, but found no foreign objects. I used the tip of my foot to make the accelerator pedal was up all the way, and then engine rpm appeared to go to normal. When I reached my destination I tapped on the accelerator pedal a few times to re-create the problem. The engine went to 2000 rpm for about 3 seconds, and came back down. I checked for any codes using an obd ii scanner, however none were found.
