2018 Lincoln MKZ

Powertrain

Powertrain and transmission defects directly impair the vehicle’s core function and are generally considered substantial defects under California lemon law. Owners of the 2018 Lincoln MKZ have reported harsh shifting, shuddering, slipping, and transmission warning lights. 10 NHTSA complaints have been submitted for this defect category. Owner reports include: “The car had an internal transmission failure and caused most of the transmission fluid to leak out between inspections. Upon removing the cv axle on driver’s side, the seal was fine and replaced along with cv axle. The fluid drained and was only about half a liter (needs about 4.5L normally). After servicing the transmission fluid, the dealership did their assessment and came to the following conclusion. “ Good Afternoon Sir We found the transmission system requires replacement due to an internal fault, including damage to the transfer shaft and bearings, with potential additional internal damage. Replacing the transmission can help restore smooth gear shifting and overall drivetrain functionality. To replace the transmission, you are looking at $9000.00 out the door. My apology on taking much longer to diagnose this properly. If you have any other questions please let me know. ” The drastic transmission failure which makes noises and engages and disengages while on cruise control shows the failure internally. Many metal pieces were found among the fluid when drained. This could and still can easily leave someone on the middle of the road with no time to drive to the shoulder. Car still has less than 100k miles with the severe transmission failure and the fluid leak which occurred prior to the transmission making noise. Essentially, the internal components caused the leak which the caused even more damage. I’m quoted $9,000 for the repair which occurred really early in the car’s life. I do a lot of longer trips away from home and can easily be left stranded in the middle of nowhere or even cause huge accidents when in heavy fast moving traffic if I lose drivability or if metal components fly off. The cv axle moves in and out of the transaxle side meaning the shaft can pop off as well.” (NHTSA Complaint #11710990)

Engine

Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act. Owners of the 2018 Lincoln MKZ have reported issues including stalling, overheating, loss of power, rough idling, excessive oil consumption, and check engine lights that return after dealer repairs.

Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act. Owners of the 2018 Lincoln MKZ have reported issues including stalling, overheating, loss of power, rough idling, excessive oil consumption, and check engine lights that return after dealer repairs. With 6 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “My 2018 Lincoln MKZ with the 2.0 Ecoboost Engine incurred premature engine failure at ONLY 40k miles. My safety as well as other drivers’ safety at risk due to EcoBoost Engine in certain model year 2013-2019 Ford and Lincoln vehicles have an inherent design defect which makes them predisposed to leak coolant, including allowing the coolant to seep into the engine cylinder, which causes overheating and cylinder head cracking, and can cause the engine to misfire, suddenly stall, or even catch fire while driving. In April the car began to “shake” at start up. The shaking was intermittent. After a few days of this, the check engine light came on. I took it to the mechanic (T&H) to have it looked at. They said the “shaking” is the car misfiring at start up. They were not able to locate any leaks or identify the cause of the misfire. They code on the check engine light was Code P0301-Cylinder #1. During April and May the misfires have continued and got worse. I was going back and forth to T&H trying to diagnose the issue. On May 12th, while taking the kids to school, I went to pull out into traffic and the car would not accelerate. The dashboard lights said the engine was overheating. The car would not go above 10mph. Luckily my mechanic is down the street. They were concerned about excessive use of coolant and not seeing a leak anywhere. They filled the coolant, and I made a follow up appt in one week to do a borescope inspection. On May 19th, T&H did a Borescope inspection and visually confirmed coolant in cylinder #1. They provided me a copy of a TSB 22-2229 that states the engine block needs to be replaced. The cost of the engine block replacement was estimated at $8k. Engine failure at 40k miles is unacceptable. An engine block replacement due to a manufacturing/design flaw should be covered by Lincoln Motor Co as a goodwill repair regardless of warranty status.” (NHTSA Complaint #11663894)

If your vehicle has experienced recurring issues in this area that the dealer has been unable to repair after multiple attempts, you may have a qualifying lemon law claim under California’s Song-Beverly Consumer Warranty Act. Owner reports include: “Upon driving north on rt. 95 in GA our pan Aramaic moonroof unexpectedly exploded. There was no apparent reason. No debris was present and environmental conditions were not extreme. ( sunny day about 72 degrees F) . The explosion was very loud and alarming creating a risk of losing control of the vehicle. Bodily injury could have resulted if the moon roof cover was open and chards of glass were shot into the vehicle. We have not contact the manufacturer yet , but plan to. There was absolutely no warning of this. It was sudden, unexpected and explosive. The tempered glass was shattered and glass was missing from all along all 4 sides of the moon roof. Very scary. I assume this is due to a manufacturing defect.” (NHTSA Complaint #11574587)

California Lemon Law — Song-Beverly Act

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.

Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2018 Lincoln MKZ:

• 4+ repair attempts for the same non-safety defect without resolution
• 2+ repair attempts for a defect likely to cause death or serious bodily injury
• 30+ calendar days out of service for warranty repairs (cumulative, not consecutive)

Once the presumption is triggered, the burden shifts to Lincoln to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Lincoln must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.

What You Can Recover

If your 2018 Lincoln MKZ qualifies as a lemon under California law, Lincoln may be legally required to:

• Repurchase your vehicle — Full refund of your down payment, all monthly payments, registration fees, and incidental costs (towing, rentals), minus a mileage offset for miles driven before the first repair attempt
• Replace your vehicle — Provide a new, comparable vehicle at no cost to you
• Pay your attorney’s fees — Under § 1794(d), Lincoln pays all legal fees if you prevail
• Civil penalty up to 2x damages — If Lincoln willfully violated the Act, courts may award double the actual damages

Steps to Protect Your 2018 Lincoln MKZ Claim

Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.

Step 2: Keep returning for repairs. You must give Lincoln a reasonable opportunity to fix the defect. Visit different authorized Lincoln dealers if needed and ask for written documentation of each visit.

Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Lincoln pays your fees if you win.

Step 4: Send a demand letter. Your attorney will send Lincoln a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.

2018 Lincoln MKZ Lemon Law Questions

How many repair attempts qualify my 2018 Lincoln MKZ as a lemon?

Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.

Does Lincoln pay my attorney fees?

Yes. Under Cal. Civ. Code § 1794(d), Lincoln is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.

Can I file a lemon law claim without an active recall?

Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.

What is the time limit to file a lemon law claim for my 2018 Lincoln MKZ?

California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
