The thought of invoking the Lemon Law sets the expectation around your issue or defect being on a new vehicle. While true that many recurring issues for a manufacturer will lead to recalls for common issues like a faulty part or a needed software update, there are other times when it will be easier to deal with the vehicles that are brought in by their owners for services. Some people refuse to buy a new model car until it has been available for purchase for a couple of years, allowing others to work out the bugs and issues, and for the manufacturer and dealers to figure out how to handle the repairs needed. The reality when it comes to Lemon Law claims is that issues will occur at any point in the ownership or lease of a vehicle. Its age and release date for purchase have little to do with issues, and even less to do with design flaws or questionable manufacturing issues that feed lemon law claims.

The California Lemon Law And What You Should Know

California Lemon Law was adopted in 1971 with the express purpose of providing consumers protection when it came to dealing with manufacturers and express warranties. The law has evolved since then. Starting with the original bill, known as the Song-Beverly Consumer Warranty Act, it required the manufacturers to repair their products that weren’t meeting the express warranty offered, including automobiles. The next evolution was the Tanner Consumer Protection Act in 1983, with firm definitions on what was previously referred to as “a reasonable attempt to repair” a defect. It also added in a total time limit of 30 days in repair efforts, and included used vehicles with existing factory warranty time periods remaining.

The final evolution took place with amendments AB1755 and SB 26, which primarily addressed procedural changes to alleviate court backlogs in Lemon Law hearings and expedite claim resolution. It also updated the Statute of Limitations on filing a Lemon Law claim, which is now 1 year after the warranty expiration, or 6 years from the date of vehicle delivery, whichever comes first. Guardian Lemon Law will review your case with a Toyota Corolla lemon law attorney to ensure that the claim is eligible under the new Statute of Limitations and the vehicle is qualified under Lemon Law. If you are looking for a lemon lawyer to sue Toyota for engine misfires, eligibility is an important first step.

The 2018-2020 Toyota Corolla Engine Misfire Issues And Customer Reports

Consumers report that initial experiences center on a rough idling feel, leading to a noticeable reduction in engine performance during acceleration and, on occasion, engine shaking. That issue manifests itself in braking, as well as a very rough idle once stopped. It seems to affect acceleration with what feels like a misfire, but it could be caused by a few different things.

Ignition system causes for misfires are usually either spark plug or plug wire related, or engine coil issues causing the plugs to fire out of order, or not firing at all. The plugs may be fouled or faulty. The cable may be loose or dirty where it connects to the spark plug. Plugs firing out of order will lead to major issues with how the engine operates and how performance is affected. The plugs need to fire at specific times related to the cylinder location, and if they are early or late, the detonation of the air-fuel mixture can cause problems inside the engine. The misfires as well as the degraded performance are immediately noticeable.

For some of the same reasons, the fuel system could also be the primary culprit. The mixture of fuel and air is as important as the spark occurring at the right time. If this mix is off, the performance is affected, and you can get sputtering and inconsistent power. Issues with the injectors being dirty or clogged, the fuel being contaminated with water, or even a faulty or failing fuel pump and rail assembly could be the cause. The injector issues are the most common.

The vacuum system affects that air to fuel mixture as well, as do the air-fuel mixture sensors, where even when slightly dirty don’t sense the air as accurately, and allow more than they should. Engine compression may also be a root cause, with too little or too much compression causing performance issues as well as fuel mileage impact. Sensors at both the MAF and O2 sensors will trigger the check engine lights on the dashboard. It becomes time to see your dealer.

The repair efforts for this issue vary quite a bit. Lots of diagnostic time and some trial and error as parts get swapped and the vehicle is test driven. It can be extremely time consuming and annoying when the issue returns. If your dealer has struggled to resolve this issue with your Toyota Corolla, then it is time to talk to Guardian Lemon Law about hiring a Toyota Corolla engine misfires lemon lawyer to represent you.
