Not only did it have a well-finished interior, but\u00a0it also happily served up a remarkably entertaining driving experience. Naturally, then, the Stinger is held in high regard by a section of gearheads, and the fact that it\u00a0<a href=\"https:\/\/www.jalopnik.com\/2221872\/how-much-2021-kia-stinger-gt-has-depreciated-in-five-years\/\" target=\"_blank\">has taken a substantial depreciation hit<\/a> and can be snatched up relatively affordably now makes it a pretty tempting value proposition. However, this also naturally raises some\u00a0questions, such as whether the Kia Stinger is reliable and what problems you are likely to deal with if you buy it. Well, as far as the 2021 model year goes, the\u00a0Kia Stinger&#8217;s reliability is average overall, with <a href=\"https:\/\/www.jdpower.com\/cars\/2021\/kia\/stinger\" target=\"_blank\">J.D. Power<\/a> giving it a quality and reliability score of 74 out of 100. However, this sports sedan isn&#8217;t without its issues.<\/p>\n<p dir=\"ltr\">Owners have reported a handful of common problems with the 2021 Kia Stinger to look out for, including hydraulic electronic control unit short circuits, <a href=\"https:\/\/www.jalopnik.com\/2237106\/what-oil-starvation-means\/\" target=\"_blank\">oil starvation<\/a>, high-pressure fuel pump failures, and\u00a0oil leaks. The 2021 Kia Stinger was also recalled five times over issues ranging from engine fire risk to loss of drive power, inaccurate fuel gauge readings, and\u00a0failing oil feed line, which can\u00a0manifest in ways like a burning oil smell and\u00a0smoke coming from the engine compartment.<\/p>\n<\/p><\/div>\n<div class=\"columns-holder \">\n<p dir=\"ltr\">While the 2021 Kia Stinger&#8217;s reliability isn&#8217;t exactly poor, the car can experience problems, one of which relates to an issue with the high-pressure fuel pump found in the 255-hp 2.0-liter turbocharged inline-four powering the base-spec Stinger GT Line. It\u00a0is known to fail due to a misalignment of the fuel control valve plunger inside it, and that inevitably leads to uneven internal wear, which can in turn cause the plunger to stick inside and over-pressurize the pump. If this happens, the engine will often lose power, making it enough of a safety risk to warrant a recall.<\/p>\n<p dir=\"ltr\">Another frequently encountered Stinger fault that has been reported by owners relates to the car shaking or shuddering during braking, with some owners seeing this problem as early as the first 10,000 miles. Bad brake rotors and bad brake pads are often to blame, according to <a href=\"https:\/\/repairpal.com\/symptom\/kia\/stinger\/shaking-when-braking\" target=\"_blank\">RepairPal<\/a>, and replacing them should be the first thing to consider, with\u00a0<a href=\"https:\/\/www.reddit.com\/r\/StingerGT\/comments\/165ax9r\/legal_action_against_kia_for_faulty_stinger_brakes\/?logging_in=true\" target=\"_blank\">comments from drivers on Reddit<\/a>\u00a0confirming them as a common culprit.<\/p>\n<p dir=\"ltr\">Another known issue that affects the 2021 Kia Stinger is\u00a0a tendency to make a rattling noise while driving.\u00a0This usually comes from sources such as the\u00a0exhaust heat shield and the license plate, but the most common one seems to be the trunk hatch. Problems can occur with the Stinger&#8217;s electronics too, and certain 2021 models were previously included in a recall due to the risk of an electrical short in the Anti-lock Brake Hydraulic Electronic Control Unit (HECU)\u00a0in Stinger models equipped with 3.3-liter twin-turbocharged V6 engines. In the worst-case scenario, the HECU could overheat, resulting in a potential risk of fire in the engine compartment.<\/p>\n<\/p><\/div>\n<div class=\"columns-holder \">\n<p dir=\"ltr\">Indeed, the 2021 Kia Stinger may have problems that collectively may seem like a lot, but that doesn&#8217;t diminish its merits as a used car option, especially when you consider the fact that it benefits from Kia&#8217;s generous warranty. Besides, most of the issues that affect the sports sedan are known, and are mostly repairable (if they haven&#8217;t already been fixed via a recall). Speaking of which, analysis by <a href=\"https:\/\/www.edmunds.com\/kia\/stinger\/2021\/cost-to-own\/\" target=\"_blank\">Edmunds<\/a>\u00a0indicates that the 2021 Stinger&#8217;s maintenance cost totals out at $8,223 after five years of ownership, with repairs alone estimated to cost $2,663 (about $532 per year).\u00a0The Edmunds-quoted maintenance cost alone is $902 more than the combined maintenance and repair costs of all\u00a0Kia models, the average of which comes out to\u00a0$7,321 over ten years (via\u00a0<a href=\"https:\/\/caredge.com\/kia\/maintenance\" target=\"_blank\">CarEdge<\/a>). However, despite its performance credentials, it is still substantially cheaper to repair than something like a BMW 3 Series ($8,006 in repairs) or an Audi A4 ($6,619 in repairs), according to Edmunds.<\/p>\n<p dir=\"ltr\">Either way, the Stinger obviously isn&#8217;t the most cost-effective choice for those\u00a0prioritizing affordable repairs. But while owners themselves recognize that the Kia Stinger&#8217;s\u00a0maintenance is not exactly cheap,\u00a0reviews on the vehicle\u00a0suggest it isn&#8217;t too substantial either, with one owner on <a href=\"https:\/\/www.reddit.com\/r\/kiastinger\/comments\/15twanf\/comment\/jwmcb9z\/?utm_source=share&amp;utm_medium=web3x&amp;utm_name=web3xcss&amp;utm_term=1&amp;utm_content=share_button\" target=\"_blank\">Reddit<\/a>\u00a0describing the maintenance costs as\u00a0&#8220;nothing crazy.&#8221;<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Add Jalopnik on Google: Preferred Source Google Discover Although it was stung by a less-than-stellar reception during its six-year life, the Kia Stinger was a magnet for positive reviews.
