No company is immune to mistakes – even global auto manufacturers. New vehicles can be produced with defects that result in serious safety problems for the driver and those around them. Vehicles are subjected to recalls and lemon claims every year for a range of issues.

If you have one of these vehicles – and it’s covered under the original warranty – the manufacturer should fix it at no cost. If they are not able to fix the defect after a reasonable number of repair attempts, you might be eligible for lemon law benefits.

Without further ado, let’s discuss the most defective car models in 2021, as reported by other sources.
